    Objective. Speech sound errors are the most common speech disorders in children that, without proper treatment, can have far-reaching effects on an individual’s quality of life. Due to limited speech therapy resources, speech sound disorders are often left without adequate treatment. In Finland, efforts have been made to reduce the geographical inequality in the availability of rehabilitation services through various time-independent teletherapy solutions. For example, the mission of Äännekoulu is to help Finnish municipalities prioritize their limited resources and enable every child to have access to speech therapy services, regardless of their place of residence. There are only few studies focusing on the use of teletherapy practicies in the treatment of speech sound disorders in Finnish-speaking children. The aim of this study was to examine whether Äännekoulu’s online therapy is an effective way to rehabilitate children's /r/-errors and to describe possible factors influencing rehabilitation results. Methods. The data used in the study consisted of demographic information and speech therapist’s notes and records on children under 10 years of age (n = 109) who participated in a three-month training period at Äännekoulu’s online therapy aiming to rehabilitate existing /r/-errors in their speech during March 2019 - April 2020. The notes and records were collected from the patient database Diarium. Participation in the study was voluntary. The collected data were categorized and analyzed using the Mann-Whitney U test and the chi-square test. Results and conclusions. More than half of the children learned to produce alveolar trill /r/ at least in isolation during a training period at Äännekoulu’s online therapy. On average children learned to produce the tongue trill on the sixth contact with the speech therapist. Most of the children learned to produce tongue trill through the dn dn dn -exercise. There was no significant difference between sexes in learning to produce the alveolar trill. The quality and the type of the speech sound error, age, sex or the children’s skill level in the beginning of the training period did not affect the rehabilitation of /r/-error. The number of contacts with the speech therapist strongly correlated with the results achieved in teletherapy. Äännekoulu’s online therapy seems to be an effective way to treat children’s /r/-errors. Learning to produce the alveolar trill correctly is significantly affected by active collaboration with the speech therapist. Further research is needed to identify the factors influencing the rehabilitation of the /r/-errors. Future research should also concentrate on the at home practice needed to treat speech sound errors in teletherapy.

    There is a little research of early pre-reading skills, such as rapid naming and letter knowledge. Also the associations between early lexicon and early pre-reading skills have been studied only a little. Earlier studies have shown that lexical development is associated with later language skills, such as development of morphology. Children with typical and small lexicon size at age 2;0 have also differed in other, later language skills. The associations between the composition of the lexicon and other language skills, and pre-reading skills as well, have been studied only a little. The aim of this study was to investigate the associations between the size and the composition of the lexicon at age 2;0 and pre-reading skills at age 3;6. The aim of this study was also to investigate whether children with typical and small lexicon size at age 2;0 differ in their early pre-reading skills. The sample included 50 Finnish-speaking children, which were part of sample in Sanaseula Study. In this study, Finnish version of the Communicative Development Inventories, Toddler version was used to study the size and the composition of the lexicon at age 2;0. LUKIVA-method was used to study pre-reading skills at age 3;6. Associations between the size and the composition of the lexicon and pre-reading skills were studied by using Spearmann’s correlation coefficients. Mann-Whitney U-test was used to study whether children with typical and small vocabulary size differ in pre-reading skills. The size and the composition of the lexicon at age 2;0 were not associated with rapid naming and letter knowledge at age 3;6. Children with typical or small vocabulary size at age 2;0 did not differ in pre-reading skills at age 3;6. Thus, small size of the lexicon at age 2;0 does not seem to be a risk factor for very early pre-reading skills in this study. Pre-reading skills are only developing at age 3;6 so that age might be too early to show the associations between lexicon and pre-reading skills. In future studies it would be interesting to study associations between the size and the composition of the lexicon at age 2;0 and later pre-reading skills, such as pre reading skills at age 5;0 and at age 6;0.

    Varhaisen sanaston koostumus kehittyy sanaston määrällisen kehityksen myötä. Sanaston koostumuksen on havaittu kehittyvän omaksuttavasta kielestä riippumatta pääpiirteittäin samantyyppisesti. Aiemmissa tutkimuksissa on löydetty yhteyksiä varhaisen sanaston kehityksen ja muiden kielellisten taitojen kehityksen välillä. Sanaston koostumuksen kehityksen yhteyttä muihin kielellisiin taitoihin on kuitenkin tutkittu vain vähän. Tämän tutkimuksen tarkoituksena oli tarkastella ilmaistun sanaston koostumuksen kehitystä toisen ikävuoden lopulla sekä sen yhteyksiä ymmärretyn ja ilmaistun kielen kokonaistasoon kaksivuotiaana. Tämän tutkimuksen otos (n = 50) koostui Sanaseula-tutkimushankkeen tutkittavista. Tutkittavat olivat terveitä suomenkielisten perheiden lapsia. Ilmaistun sanaston koostumusta mitattiin 18 ja 24 kuukauden iässä Varhaisen kommunikaation ja kielen kehityksen arviointimenetelmällä. Menetelmästä käytettiin Lapsen kommunikaation kehitys: Sanat, taivutukset ja lauseet -versiota. Ilmaistun sanaston koostumusta tarkasteltiin sanakategorioiden raakapisteiden, word opportunity -pisteiden sekä kokosanamäärästä laskettujen prosentuaalisten osuuksien avulla. Ymmärretyn ja ilmaistun kielen kokonaistasoa mitattiin 24 kuukauden iässä Reynellin kielellisen kehityksen testillä sekä Bayley III -testin kielellisen kehityksen asteikolla. Ilmaistun sanaston koostumuksen sekä ymmärretyn ja ilmaistun kielen kokonaistason välisiä yhteyksiä tutkittiin Spearmanin korrelaatiokertoimien ja lineaaristen regressiomallien avulla. Ilmaistut sanastot koostuivat 18 kuukauden iässä enimmäkseen sosiaalis-pragmaattisista sanoista sekä substantiiveista. Toisen ikävuoden lopulla tutkittavat omaksuivat ilmaistuihin sanastoihinsa erityisesti substantiiveja sekä verbejä. Sosiaalis-pragmaattisten sanojen prosentuaalinen osuus pieneni, kun taas muiden sanakategorioiden prosentuaaliset osuudet kasvoivat toisen ikävuoden lopulla. Ilmaistun sanaston koostumuksen yhteydet ilmaistun kielen kokonaistasoon olivat pääosin vahvempia kuin vastaavat yhteydet ymmärretyn kielen kokonaistasoon. 24 kuukauden iässä mitattu ilmaistun sanaston koostumus korreloi pääosin 18 kuukauden iässä mitattua vahvemmin kahden vuoden iässä mitatun ymmärretyn ja ilmaistun kielen kokonaistason kanssa. Ilmaistun sanaston sanakategorioiden raakapisteet 18 ja 24 kuukauden iässä selittivät yhdessä sukupuolen kanssa ymmärretyn sekä ilmaistun kielen kokonaistasoa kahden vuoden iässä tilastollisesti merkitsevästi. Ilmaistun sanaston koostumus selitti selvästi paremmin ilmaistun kielen kokonaistasoa kuin ymmärretyn kielen kokonaistasoa. Tutkimuksen tulokset tukevat näkemystä, että tyttöjen varhaiset kielelliset taidot ovat keskimäärin poikia paremmat, ja että varhaisessa kielenkehityksessä ilmenee huomattavaa yksilöllistä vaihtelua. Tulokset osoittavat, että varhaisen sanaston koon arvioimisen lisäksi on aiheellista tarkastella myös sanaston koostumusta, sillä näin saadaan tarkempaa tietoa lapsen varhaisista kielellisistä taidoista.

    Aims. In face-to-face communication, information contained in speech is also transmitted visually via observing articulation movements on the speaker’s lips and face. Silent lipreading is difficult since many of the phonemes of spoken language look visually similar and thus fall within the same viseme categories. Lipreading at single word level requires at least some of the phonemes to be recognized with sufficient accuracy in order for lexical activation to reach the correct target word in the observer’s mental lexicon. Word-level lipreading is also guided by language specific phonotactics, but its’ contribution to lipreading is not well understood. Lipreading ability shows great individual variation in both normal hearing and hearing-impaired populations. There is currently a lack of lipreading assessment tools in logopedic clinical practice in Finland. The aim of this study was to develop a Finnish single word lipreading test that can be delivered via a web application. I examined whether word videos produced in the Huulioluku research project can be used to measure lipreading ability in normal hearing adults and which test procedure appears to be functional. In addition, viseme analysis was used to examine features that contributed to the lipreadability of individual test words. Methods. The lipreading task used in this study consisted of word videos (43 Finnish words containing 2-3 syllables) developed in the Huulioluku research project. The participants (N=60) were normal hearing adults aged from 18 to 50. The data was collected remotely in March 2021 via a web application. Participants viewed silent word videos spoken by a female speaker and indicated which word had been said via a free text response. A point was given to each response that matched the target entirely. Deviation in participants’ scores (max 43 points) and the proportion correct for individual words were analysed. In a qualitative part of the study, the most frequent erroneous responses for each individual word were collected and a viseme comparison between the target and error response was carried out. Results and conclusions. The lipreading test showed great individual variation in the participants’ lipreading ability (score range between 1 and 34). The percentage correct for individual words ranged from 0 to 78 %. A short test of 20 best recognised words also showed great individual variation, with scores ranging from 20 to 1, suggesting that it could be used as such in future test developments. As seen in previous research, words with the least amount of visual competitors in the lexicon were recognized with the most accuracy. Consonants /v/ /p/ and /s/ were highly recognizable, whereas /r/ and /n/ were poorly recognized. The ability to perceive phoneme duration accurately as short/long proved important in recognition of Finnish words. Vowel discrimination was facilitated by a feature in the Finnish language phonotactics – vowel harmony. The words used in the test assessed the ability to lipread Finnish language specific phonological, morphological and prosodic features, which suggests that the 20-word test may be a valid tool.
  • Kettunen, Ursula (2024)
    Tavoitteet. Tässä maisterintutkielmassa tarkastellaan, millaisia sanoihin liittyviä ongelmia 5-vuotiaiden lasten ja heidän aikuisten vuorovaikutuskumppaniensa välisissä keskustelutilanteissa ilmenee ja miten niitä käsitellään. Tutkimuksen kohteena ovat sekä lapsen että aikuisen tekemät itsekorjaukset ja toisen vuoroon kohdistuvat korjausaloitteet yksittäisiin sanoihin liittyen. Erilaisten korjauskäytänteiden avulla pyritään säilyttämään keskustelijoiden välistä yhteistä ymmärrystä. Itsekorjauksilla tarkoitetaan puhujan omaan puheeseen kohdistuvia korjauksia, kun taas toisen puheeseen kohdistuvilla korjausaloitteilla nostetaan esille jotain toisen puhujan puheessa ongelmalliseksi tulkittua. Ilmiötä tarkastellaan kahdessa erilaisessa vuorovaikutustilanteessa, joista toinen on puheterapeuttinen arviotilanne ja toinen äidin ja lapsen välinen leikkitilanne. Lisäksi verrataan, onko sanoihin liittyvien ongelmien esiintymisessä tai käsittelyssä eroa eri vuorovaikutustilanteiden välillä. Menetelmät. Tässä tutkielmassa aineistona oli videoituja vuorovaikutustilanteita neljältä eri lapselta, jokaiselta sekä leikkivuorovaikutustilanteesta että puheterapeuttisesta arviosta. Aineisto on kerätty osana Lapsen kehittyvä kieli ja vuorovaikutus -tutkimushanketta (nyk. COMPAIR). Aineiston analyysi perustuu keskustelunanalyysiin, jonka perusteella aineistosta poimittiin sanoihin liittyvät korjausjaksot. Tulokset ja johtopäätökset. Yksittäisiin sanoihin liittyviä ongelmakohtia nostettiin käsiteltäviksi monista eri syistä. Ongelmia koettiin ja nostettiin käsiteltäviksi enemmän leikkitilanteissa kuin puheterapiatilanteissa. Näitä kohtia käsiteltiin keskustelutilanteissa aikuisen tai lapsen aloittamilla itsekorjauksilla, lapsen tai aikuisen tekemillä toisen vuoron korjausaloitteilla sekä aikuisen tekemillä suorilla korjauksilla. Sanoihin liittyvien korjauskäytänteiden määrässä oli suurta vaihtelua eri lasten vuorovaikutustilanteissa, mikä voi johtua esimerkiksi lapsikohtaisesta vaihtelusta kielellisissä taidoissa tai eri vuorovaikutuskumppaneiden välisistä erilaisista kommunikointityyleistä. Lasten tekemät itsekorjaukset olivat enimmäkseen sanahakuja, joiden lisäksi ilmeni sanan äännerakenteen tuoton haasteisiin liittyviä itsekorjauksia sekä sanan korvaamista toisella sanalla. Aikuiset puolestaan tekivät itsekorjauksia tyypillisimmin korvaamalla sanomansa tai aloittamansa sanan toisella lapselle mahdollisesti helpommin ymmärrettävällä sanalla. Lapset nostivat muutaman kerran aikuisen käyttämän sanan merkityksen ongelmalliseksi keskustelussa. Sen sijaan aikuiset tekivät sanoihin liittyviä toisen puheeseen kohdistuvia korjausaloitteita useimmin liittyen lapsen käyttämän sanan oikeellisuuteen. Vuorovaikutustilanteen yleinen luonne saattoi vaikuttaa sanoihin liittyvien ongelmien ilmaantumiseen sekä niiden käsittelyyn. Tutkimuksen tuloksista saadaan alustavaa tietoa viisivuotiaiden lasten ja heidän aikuisten vuorovaikutuskumppaneidensa tavoista käsitellä erilaisia esiin nousevia sanoihin liittyviä ongelmakohtia erilaisissa vuorovaikutustilanteissa. Sanoihin liittyvien ongelmakohtien selvittely osaavamman vuorovaikutuskumppanin kanssa auttaa lasta uuden sanaston oppimisessa, ja siksi aiheesta on tärkeää saada tutkimustuloksia tyypillisesti kehittyneiden lasten osalta. Ilmiötä on kuitenkin tärkeää tutkia lisää isommilla aineistoilla, jotta tuloksia voidaan yleistää ja myöhemmin hyödyntää puheterapeuttisessa arvioinnissa ja kuntoutuksessa.

    Tavoitteet. Moniammatillinen yhteistyö on sosiaali- ja terveysalalla merkitykseltään kasvava työskentelytapa. Tässä maisterintutkielmassa tarkastellaan ammattilaisten kokemusta työskentelystä moniammatillisessa yhteistyössä lastenneurologisessa kuntoutuksessa. Tarkoituksena on selvittää minkälaisia arvoja moniammatillisen työryhmän jäsenet liittävät omaan työhönsä. Tutkielma myös selvittää miten moniammatillinen yhteistyö toteutuu lastenneurologisessa kuntoutustyöryhmässä ja mitä moniammatillinen yhteistyö vaatii onnistuakseen. Menetelmät. Tutkimuksen aineisto on nauhoitus ryhmähaastattelusta, jossa kahdeksan moniammatillisen tiimin jäsentä keskustelivat kokemuksestaan moniammatillisessa työryhmässä työskentelystä. Moniammatillisen tiimin jäsenistä haastateltiin puheterapeuttia, fysioterapeuttia, toimintaterapeuttia, AAC-ohjaajaa, ohjaavaa opettajaa, tiimiohjaajaa ja kahta erityisluokanopettajaa. Aineisto analysoitiin aineistolähtöisen temaattisen analyysin keinoin. Tulokset ja johtopäätökset. Temaattisen analyysin pohjalta aineistosta havaittiin neljä yläteemaa ja niitä tukevia alateemoja, joita löydettiin yhteensä kolmetoista. Moniammatillisen työryhmän kuvaamana moniammatillisuus toteutuu arjen työskentelyssä, työntekijöiden jakaessa osaamistaan ja tarjotessaan toisilleen vertaistukea. Myös kuntoutus toteutetaan osana arjen toimintaa. Työryhmän vuorovaikutuksessa korostuu moniammatillisen keskustelun merkitys osana moniammatillista yhteistyötä. Moniammatilliseen yhteistyöhön liittyvään vuorovaikutukseen liitetään myös sääntöjen ja rajanvedon sekä ohjeistamisen merkitys. Ammattilaisilla on eroavia kokemuksia omasta roolista työryhmässä. Työryhmän kokemuksen mukaan moniammatillinen yhteistyö kehittyy ja muuttuu sujuvammaksi ajan kanssa, kun työryhmän jäsenet tutustuvat toisiinsa. Työryhmä kehittyy myös oppimalla toisiltaan jatkuvasti. Moniammatillisen yhteistyön onnistumiseen liittyy sekä yksilön että tiimin kehittyminen. Moniammatillisten työntekijöiden yhdessä työskentely asettaa vaateita sekä yksilölle että organisaatiolle. Tutkimuksen perusteella voidaan havaita, että moniammatillisuus koetaan työryhmässä mieluisana työskentelytapana ja työntekijät liittävät siihen lukuisia hyötyjä. Moniammatillisen työskentelytavan onnistuminen vaatii aikaa ja sopivia ihmisiä sekä oikeita organisaation tarjoamia olosuhteita.

    Aims. Speech processing has traditionally been studied with simple paradigms that do not take the variety of natural speech perception situations into consideration. Speech processing in everyday situations becomes more difficult if, for example, the auditory quality of speech is poor, there are other distracting voices in the listening environment or if the semantic context of the conversation is not clear. Nevertheless, humans possess an exceptional capability to selectively attend to a specific speech stream even in suboptimal listening conditions. In a recent functional magnetic resonance imaging (fMRI) study, participants followed audiovisual dialogues amongst distracting speech. The dialogues were presented in various experimental conditions including two different levels of semantic predictability. The results gave support to the novel notion that high-level semantic information has an impact already at lower levels of auditory processing. The aim of the present study was to examine whether support for this notion would be demonstrated using a method that has a better temporal resolution than fMRI. I examined the effects and interaction of semantic context and selective attention in the processing of naturalistic speech using the same stimuli as the recent fMRI study but collected neurophysiological data with electroencephalography (EEG) as it has a temporal resolution of milliseconds. Methods. Thirty adults selectively attended to audiovisual two-person dialogues with distracting speech in the background during EEG recordings. Half of the dialogues had a coherent narrative and the other half consisted of mixed lines from unrelated dialogues. The participants answered questions on dialogue content. In addition, the participants carried out a visual control task during which they were instructed to ignore all speech. I analyzed behavioral performance and event-related potentials (ERPs) timed to the beginning of dialogue lines in the two tasks. Results and conclusions. Based on the behavioral results, a coherent semantic context enhanced speech intelligibility. The ERP results suggested that semantic contextual coherence modulated the processes of auditory selective attention at around 180 ms after dialogue line onset. This attentional effect was significant only when the dialogues were attended to, and the semantic context was coherent. Furthermore, the beginnings of lines in incoherent dialogues elicited a P300 effect which could be linked to memory-related operations of contextual updating. Alternative interpretations are discussed. In conclusion, the present study provides both behavioral and neural evidence that semantic contextual information enhances the processes of auditory selective attention in compromised listening conditions. A coherent semantic context seems to facilitate the processing of contextually relevant information through semantic priming already at early stages of auditory attentional processing.

    Aim. The purpose of this study was to examine cross-language relationships between receptive and expressive vocabulary in first and second language. Previous studies have reported various cross-linguistic relationships ranging from positive correlations to non-significant and negative correlations. In addition, this study investigates how various factors are related to receptive and expressive vocabulary in L1 and L2. Also, the correlations were studied between children’s vocabularies and the questionnaire filled by parents and kindergarten teachers. Method. The receptive and expressive vocabularies were measured in first and second languages. The children who participated (N=21) were between 4 and 6 years old. The participants spoke Arabic or Russian as their first language and had attended Finnish kindergarten. The assessment of first language was performed in co-operation with an interpreter. Parents also assessed children’s linguistic proficiency in L1 and kindergarten teachers in L2 by filling questionnaires. The sample was analysed by using statistical methods including correlation analysis and linear regression. Results and conclusions. While examining the whole group there were no significant correlations between languages. In the Russian speaking group, there was found a significant positive correlation between L1 and L2 in receptive vocabulary. In the Arabic speaking group, the cross-language relationships were negative both in receptive and expressive vocabulary. The expressive vocabulary in L2 was associated to L2-language exposure, length of participation in Finnish kindergarten and father’s education. However, the only statistically significant predicting variable was the amount of L2 exposure. Parental ratings correlated with children’s receptive and expressive vocabulary in L1. In L2, the ratings scored by kindergarten teachers correlated with expressive vocabulary but not with receptive vocabulary. The findings of conflicting associations were similar in previous studies about cross-language relationships in vocabularies. Further research is needed to draw more reliable conclusions

    Objectives. The aim of this thesis was to obtain information about the development of pointing gesture use among typically developing Finnish speaking children, at the age of 1–3 years. Pointing gesture use was analysed every six months at 1;0, 1;6, 2;0, 2;6 and 3;0 years. The relation between children’s pointing gesture use and vocabulary development at the age 3 and 5 was explored. Relation between the use of pointing gestures and language development has been found in many international studies, but with regard to Finnish, there is only little research on pointing or use of gestural communication in play situations between children and parents. Methods. The data consisted of video recordings of five children and the results of language tests evaluating children’s vocabulary development. The video material was annotated with computer software ELAN. ELAN was used to mark the pointing gestures used by the children and the types of these pointing gestures (declarative/ imperative pointing). Childrens vocabulary development was assessed with Bo Ege test at the age of 3, and with the Boston Naming Test and Type/Token Ratios at the age of 5. Tables, graphs and calculation of percentages and means were used as statistical description of the phenomena. Non-parametric statistical tests were also used: The Friedman test to determine the distribution of pointing gestures used by children in different age points 1;0, 1;6, 2;0, 2;6 and 3;0, and Spearman’s Rank correlation coefficient to explore the re-lation of pointing gestures and vocabulary development. Results and conclusions. All children used pointing gestures, althought there were notable individual differences in the amount of pointings. The greatest increase in the quantity of pointings used was found between the age range 1;0–1;6 years. Children used most pointing gestures at the age of 1;6. All children used considerably more declarative than imperative pointings. The proportion of declarative pointings of the pointing gestures used, increased between the ages 1;0–1;6 and then remained constant until the age of 3;0. No significant correlations were found between pointing gesture use and vocabulary development. However, from this thesis, it appears that children with typical vocabulary development tend to use pointing gestures to a large extent, and of the pointings they use, the proportion of declarative pointing gestures is considerably higher than the imperative ones.

    Speechreading is a technique of understanding speech by interpreting visual information from the speaker’s face. Speechreading is a skill that can be trained and to determine the need for rehabilitation and monitor the progress a reliable assessment tool is needed. In Finland, there does not exist any online assessment tool that can be used to assess sentence-level speechreading skills in adults. This study aimed to find out how well the 100 CID Everyday Speech sentences used in the assessment of speechreading skills are suitable for the assessment of speechreading skills when translated into Finnish. This thesis examined how Finnish-speaking normal-hearing adults aged 18–65 perform sentence-level speechreading tasks, whether sentence length affects performance, and whether CID sentences differentiate speechreading skills when translated into Finnish. Study participants (n = 38) were normal-hearing adults aged 18–65 with no reported learning disabilities. The data was collected from an online speechreading test responses and analyzed by statistical methods with the R programming language. The translated CID sentences were divided into ten collections of ten sentences and comparisons were then made between those collections. Participants’ performance was examined using the Friedman test and post-hoc testing was done with the Durbin-Conover test. The consistency in the responses between collections was assessed using Spearman’s correlation coefficient. Sentences were also divided into groups by word count and both the Friedman test and the Durbin-Conover test were used to examine these groups. The translated CID Everyday Speech sentences differentiate speechreading skills well. Statistically significant, moderate, or strong positive correlations were found in the responses between the sentence collections. The word count of the sentences was found to be connected to the percentage of words recognized correctly. Based on the results the translated CID sentences are suitable for assessing the speechreading skills in normal-hearing adults. Based on the results it could also be possible to divide the collection of 100 sentences into shorter collections, which could for example be utilized in monitoring speechreading rehabilitation.

    Background. Aphasia is a deficit of language and cognition caused by brain damage. Rehabilitation is based on reactivating and reorganizing the nervous system – or learning things anew. Learning is based on many factors, that would require more thorough examination to best allocate and plan rehabilitation. The impact of reaction speed on the ability to learn novel words has not yet been studied in aphasic patients, although inter- and intraindividual variability in their reaction times clearly exists. Some aphasic patients have also been associated with a behavioral pattern called speed-accuracy trade-off, a pattern where a person balances between acting fast or accurately. This has led to overly cautious or overly hasty responding in some aphasic patients, which potentially could influence the learning ability. Objectives. The purpose of this study is to examine reaction times and response accuracy and their possible relationship in a novel word learning task in aphasic patients and healthy controls. Special interest is placed on the occurrence of speed-accuracy trade-offs, or overly cautious or fast responding related to response accuracy outcome. Additionally, it is being examined if intrapersonal variability in reaction times predicts novel word learning ability. Methods. The participants of this study consist of 10 aphasic patients in subacute stage and 21 healthy age-matched controls. This study was executed as a part of “Opi sanoja” research project, in which novel word learning ability was studied through a computer-based word learning task. The purpose of the task was to learn six pseudo-words associated with a picture. The pictures were shown in pairs, of which the examinee was told to choose the right one according to seen and heard pseudo-word and earlier received feedback. Reaction speed was measured by reaction times recorded by the word learning task. Reaction times were compared with response accuracy in and between the study groups. Results and conclusions. Aligned with previous studies, aphasic patients learned novel words worse than the controls, although great interindividual variability was noted. The reaction times of aphasic patients were significantly slower, but again interindividual variability was large in the group. Reaction speed correlated with novel word learning in the control group, but not significantly in the aphasic group. Intraindividual reaction time variability was notable in both groups, being twice as large in the aphasic group. Broader intraindividual variability correlated with weaker novel word learning ability in the control group. The speed-accuracy trade-off pattern occurred in two aphasic patients: one with overly cautious and one with overly hasty response behavior. According to this study, examining reaction times and possibly speed-accuracy trade-offs with, for example, a specific learning test would help to recognize the patients with maladaptive timing patterns. This would benefit the patient, as optimizing the speed-accuracy trade-offs has been studied to improve item naming, the effect even being transferred to connected speech. The relationship of speed-accuracy trade-offs with novel word learning requires further studying, taking into consideration factors behind reaction times and word learning ability.

    Understanding early language development is crucial for identifying atypical developmental features. Syntactic development stages and typical characteristics in Finnish-speaking children at the end of their second year are not yet fully understood. Research data has been gathered, for instance, regarding the emergence of word combinations at the end of the second year and the mean lengths of utterances. The aim of this master's thesis is to examine the syntactic structures in the utterances of Finnish children at 18 and 24 months of age and to determine whether the utterances can be classified based on their syntactic characteristics. Additionally, the objective is to investigate the relationship between the development of morphology and the development of verbs and closed-class words in relation to a child's syntactic development stage. The participants in this study are 49 typically developing Finnish-speaking children learning Finnish as their first language. The sample for this thesis consists of participants from the Sanaseula research project. In this thesis, data collected through the Finnish version of the MacArthur Communicative Development Inventories (MCDI, 16–30-month version) is analyzed. Information was gathered from parents when the children were 18 and 24 months old. At both measurement points, the verbs and closed-class words acquired by the children, inflectional forms, and the three longest utterances produced by the children were collected. The utterances were classified using a syntactic development scale created for this thesis. Spearman's rank correlation coefficients and linear regression analyses were used to investigate relationships between variables. At both measurement points, there was significant variation in children's syntactic abilities, with the highest variation occurring at 24 months of age. At eighteen months, the combined number of verbs and closed-class words acquired significantly explained the variation in syntactic development stage determined at 18 months of age. The number of inflectional forms acquired at two years of age significantly accounted for the syntactic development stage at 24-months. The study generated new and detailed information on the variability of syntactic development. The observed wide variation in syntactic skills enhances our understanding of the dispersion of language skills at the end of the second year. The findings of the study also tentatively suggest a high explanatory value of inflectional form mastery, verb acquisition, and closed-class vocabulary in syntactic skill variation.

    Aims. Long-term rehabilitation of post-traumatic brain injury can be stressful for rehabilitators and is often costly for society. There is a great need for new rehabilitation practices, that are both multimodal and motivating. Dance rehabilitation can be a considerable form of rehabilitation for those with severe brain injury because it can potentially rehabilitate several dimensions simultaneously. There are a variety of changes in the communication skills of people with severe brain injuries that affect an individual’s inner circle and everyday functioning. Identifying these changes is paramount in planning and targeting rehabilitation. Because post-traumatic brain injury is typically associated with incomplete symptom awareness, the assessment of the rehabilitative close others plays an important role. The purpose of this study was to investigate the effect of dance rehabilitation on the communication of adults with severe brain injury. Although dance has been researched and utilized in neurological rehabilitation to some extent, no research has been conducted on the effect of dance rehabilitation on the communication skills of a person with traumatic brain injury. Methods. The study included 10 adults aged 19 to 45 years with severe brain injuries. Rehabilitators participated in a dance rehabilitation intervention for 2 hours per week for 3 months. In addition, 10 well-known people close to the rehabilitator participated in the study. Subjects (N = 20) assessed the rehabilitator’s communication skills using the La Trobe Communication Questionnaire at the beginning and end of the dance rehabilitation intervention. Responses from rehabilitators and their close others were examined in five different content areas of communication. Analyzes of the research data were performed by statement groups by calculating the mean variables at the beginning and end of the intervention using statistical methods. In addition, the evaluations of the rehabilitator and the close other were compared. Results and conclusions. In this study, there was no statistically significant change in the estimates of rehabilitators and their close others at the beginning and end of the intervention. There was also no statistically significant difference in the assessments of the rehabilitators and their close others. Communication skills of people with brain injuries have not been previously studied in the context of a dance rehabilitation intervention. Further research is needed on both the rehabilitation of communication skills for severe brain injury and the effectiveness of dance rehabilitation.

    Background and Objectives. An individual with complex communication needs mainly communicates otherwise than by means of speech, for example by sign language, writing or a communication device. However, the purpose of the messages may remain unclear to the communication partners. A person may be at risk of being left out in interaction situations. In order to set rehabilitation goals, it is advisable to evaluate communication skills using a variety of methods, and it is therefore justified to look for new kinds of assessment methods. The purpose of this study was to try out two assessment methods from the EMC3 communication assessment and rehabilitation model: sensory assessment and communication assessment. It is known that the EMC3 method has not been widely used in Finland, and there are no international publications available on it. The EMC3 method is based on mapping out interesting sensations and individual responses and, based on them, creating meaningful rehabilitation goals for communication. Method. In this qualitative case study, the EMC3 method was tested on one five-year-old child with autism spectrum disorder. The research material consisted of interviews and comments by two speech therapists, one occupational therapist, and the child's father, as well as the author's observations regarding the method. The interviews were transcribed and the material was analyzed using qualitative content analysis. Results. Based on sensory assessment some new sensations of interest to the child were found, as well as surprising things about how the child acted. On the other hand, some of the issues that emerged in the assessment contradicted previous knowledge. The child participating in the study may have been more skilled than the intended target group of the method. On the basis of the assessment, the people involved in the study suggested some goals for communication rehabilitation, but setting goals was also perceived challenging. The assessment gave the child's father new ideas for diversifying communication with his child. The goal to determine the meaning of a particular sense did not seem valid. Instead, information about attractiveness of individual stimuli was provided. The Communication Assessment questionnaire proved useful in collecting basic information about a child's communication skills in different situations. Conclusions. Sensory assessment in combination with the Communication assessment questionnaire may be a useful part of creating the goals of communication rehabilitation for a person who communicates at a prelinguistic level. Individual interests that have emerged in the sensory assessment could be used to create successful interaction situations, and thus to increase the motivation and opportunities for communication in people who communicate in a pre-linguistic way.

    Aims. There are many individual, hereditary and environmental factors affecting children’s language development. However, there are relatively few studies studying background factors related to preschool-aged Finnish children’s language development. The aim of this study is to study the possible effect of background factors to language development of preschool-aged children. Background factors included to this study are gender, familial risk of dyslexia and education of parents. Methods. The data is part of the LEINIKKI study data. The participants (n = 50) were healthy, Finnish-speaking children aged 3;2–4;0. Participants were evaluated with LEINIKKI method, Reynell Developmental Language Scales and LUKIVA method’s subtest for familial dyslexia. Group differences were analyzed for each of the background factors by descriptive statics and Mann-Whitney test. Finally, all the variables were analyzed together with a linear regression model. Results and conclusions. Gender was statistically significantly correlating with language skills. Preschool-aged boys had weaker overall language skills and receptive language skills. In this study, risk for familiar dyslexia or parents’ education wasn’t affecting the language skills of the child. The explanatory power of the linear regression model was weak suggesting that there are also many other additional variables affecting the language development of the children in this age. The results of this study suggest that boys’ language development should be paid attention to. In this study, familial risk for dyslexia didn’t affect to chldren’s language skills. It seems that in Finland, education of parents isn’t as strongly correlated to preschool-aged healthy children’s language development as reported in international research. In addition to the background factors studied in this study, there seems to be also many other background factors that affect children’s language development in preschool age. Further studies on these background factors are needed to gain deeper understanding of children’s language development in preschool age.

    Objectives. As the diagnosis of autism spectrum disorders increases, the number of people with ASD who may benefit from speech therapy methods will also increase. People in the autism spec trum have been found to be interested in technology in many studies, so it could be beneficial and smart to utilize it in the context of rehabilitation. In particular, the utilization of 3D and virtual real ity, as well as the usability of HMD-technology are at the center of many research regarding the potential use of technology in ASD rehabilitation. The aim of this literature review is to determine what kind of technological devices, softwares and the types of tasks performed with them are used in the context of ASD. The aim is also to determine what kind of user experiences with these meth ods and technologies have been reported by people with ASD. Methods. The research method of this dissertation is a literature review. The data was collected from five international databases (ACM digital library, Ovid Medline, Pubmed, Scopus, Web of science) using the search phrase (autism* OR autism spectrum disorder* OR high functioning au tism* OR HFA* OR Asperger* OR pervasive disorder*) AND (intervention* OR rehab* OR reha bilitation* OR therap* OR training) AND (virtual* OR augmented* OR “mixed* vr” OR HMD OR headset OR “head mounted” OR head-mounted* OR helmet OR glasses OR goggles OR ve OR im mersive OR immersion OR 3D OR head-worn OR “head worn”) AND (“computer assisted” OR computer-assisted OR “computer aided” OR computer-aided). In accordance with the selection criteria, 17 original studies were selected for the dissertation, regarding technologies and methods used in ASD rehabilitation. Findings and conclusions. Rehabilitation for ASD utilizes technology assistance from traditional computer and video game -technologies to wearable HMD-devices and virtual reality. The technol ogies used in the studies were mainly computer-implemented virtual software and virtual environ ments. About half of them utilized wearable HMD technology. The methods were mainly focused on various problems of social interaction, such as attention, emotion recognition and cooperation skills. People with ASD reported mostly positive reviews of technology-assisted methods, includ ing the use of wearable devices.

    Objectives The present study is a Finnish survey of literacy skills and literacy teaching of children and young pupils studying by the activity areas. Teaching by the activity areas is part of special support. Severely disabled pupils and pupils with severe chronic illnesses usually attend area-of-activity teaching as they are unable to follow the subject-specific curriculum. Literacy is an essential skill in everyday life which is why learning of literacy is also justified for students studying by the activity areas. Reading is a complex process that requires mastery of various skills. Previous studies show that the development of literacy in people with disabilities broadly resembles the development of literacy in typically developed peers. However, poor cognitive skills of people with disabilities usually make the process of learning to read more difficult and time consuming. Hence development of literacy skills in people with disabilities requires time, multiple repetitions as well as regular and systematic practice of reading. The aim of the study was to survey whether literacy is taught to pupils studying by the activity areas, what level of literacy skills are usually achieved by these pupils and what teaching methods and materials are used to teach literacy for pupils studying by the activity areas. Methods The study was conducted as part of the INTO project (inclusion and area-specific curriculum) carried out by the universities of Helsinki and Jyväskylä. INTO project studies teaching by the activity areas in Finland. The present study was an interview study. Research material collected and analyzed in the study consisted of interviews of 85 teachers teaching pupils studying by the activity areas. Alltogether 406 pupils were taught by the teachers interviewed in the study. One interview question focused on teaching pupils studying by the activity areas to read. From the conducted interviews, I collected and analyzed all the mentions of and references to reading. Results and Conclusions About half of the pupils studying by the activity areas got reading lessons. Wether pupil had reading lessons depended largely on the pupil's general abilities. For most pupils literacy skills remained on the pre-reading level. A small proportion of pupils had learned to read on word- or sentence-level. Ability to learn to read on sentence-level may suggest that it might be possible, at least in part, to organize the teaching of these pupils according to the subject-specific curriculum. The teachers interviewed in the study mentioned various different methods and materials that they use to teach pupils to read and emphasized experimental approach to teach reading. Analytical and synthetic methods were both commonly used when teaching pupils to read. Further research in litteracy skills and litteracy teaching of children and young pupils studying by activity areas is needed.

    Background and goals. This thesis explores the number, quality and context of initiations and corrections to another's speech in an everyday aphasia conversation where one party has fluent aphasia. The initiation refers to the turn by which the interlocutor makes it clear that a previous turn is partially or completely problematic, or wants it to be refined. In this study, initiations are categorized into open requests, restricted requests, restricted offers and class other. Classification has been further extended to these subcategories. In the previous research literature, aphasia has been found to cause an emphasized role of the interlocutor in managing communication problems. The aphasia class and severity of the aphasic person have also been shown to influence the aphasic person's ability to make other-initiations and the interlocutors' preference to use candidate understandings in aphasia conversations where one party has fluent aphasia. Methods. The study's everyday aphasia conversation data have been collected as part of Managing the problems of speaking and understanding in conversations of speakers with aphasia -research project. The data for this thesis is constituted by the dyadic or three-party conversations of seven aphasic individual with their close persons. The data was annotated using ELAN according to the finished classification created in the COMPAIR project. For this study, it was important to find all other-initiations as well as other-corrections and to classify them. Results and reflection. Aphasic individuals used many of the same other-initiations as their interlocutors. However, aphasic persons did not use all the other-initiations that the interlocutors did, and they did not produce any other-corrections at all. On the other hand, the interlocutors used other-corrections relatively often. Aphasic individuals and interlocutors prefer different other-initiations. Neither the aphasia class nor the severity of aphasia was found to be related to the number of other-initiations by the aphasic person nor the preference for use of the categories, but they were found to be related to the other-initiations made by the interlocutor. Aphasic persons and interlocutors also used other-initiations with different types of problems. Fluent aphasia seems to weaken the aphasic person's ability to correct the interlocutor's speech, but on the other hand, it also increases the need for other-initiations and other-corrections made by the interlocutor to achieve mutual understanding. However, the results were unreliable due to low inter-annotator reliability.

    Tavoitteet. Tutkimuksen tavoite on selvittää, millaisia toisen puheeseen kohdistuvia korjausaloitteita 4-vuotiaat suomenkieliset lapset tyypillisesti tekevät. Huomion kohteena ovat vuorovaikutuksen ongelmat, joita korjausaloitteilla pyritään ratkomaan sekä lasten käyttämät korjausaloitetyypit. Menetelmät. Tutkittavana on 10 normaalisti kehittyvää suomenkielistä 3;11–4;1 lasta. Jokaista lasta on kuvattu leikkimässä noin tunnin verran oman vanhempansa kanssa. Korjausaloitteita analysoidaan keskustelunanalyysin keinoin videonauhalta. Analyysin pohjana on suomenkielisessä tutkimuksessa vakiintunut tapa jaotella korjausaloitetyyppejä. Tulokset ja pohdinta. Aineistossa esiintyy korjausaloite-esiintymiä melko vähän. Lasten käyttämät korjausaloitetyypit ovat vahvasti sidoksissa ratkottaviin vuorovaikutuksen ongelmiin. Lapset käyttävät korjausaloitetyypeistä useimmin ymmärrysehdokkaita, joiden avulla ratkotaan kolmea neljästä eri ongelmatyypistä. Ratkottavat ongelmatyypit ovat kuulemisen tai epätarkan kuulemisen ongelmat, viittaussuhteisiin liittyvät ongelmat sekä muut ongelmat. Korjausaloitteiden huomattavan pieni määrä poikkeaa aiemmista tutkimuksista. Osin samoja lapsia on tutkittu 3;6 vuoden iässä, jolloin lapset tekivät enemmän korjausaloitteita.

    Existing research has yet to explore the production of Finnish children's /r/ sounds and their phonetic variants, despite /r/ sound errors being among the most common speech sound disorders in children. In addition, existing research mainly relies on perceptual observation, which presents challenges when it comes to accurately identifying the quality of the sound error. The use of more objective methods of analysis is essential for the comparability of the research data. The aim of this study was to determine how acoustic analysis and ultrasound analysis can provide new insights and information about the typical and atypical /r/ productions produced by children. This study was conducted as part of the Enhancing visual feedback with ultrasound project, and the results will be used to design an acoustic analysis protocol to measure the effectiveness of controlled ultrasound intervention. The subjects in this study were four boys aged 10–11 years, all of whom produced the Finnish /r/ sound atypically, as well as two control subjects who had already acquired the typical Finnish /r/ sound. The subjects’ different /r/ productions were examined in the study by acoustic analysis and ultrasound analysis. In the Praat program, it was possible to visually observe the manner of articulation, the number of closing and opening phases (vibrations) characteristic of trills, the qualitative variation in the closing phases and the frequency structure of the /r/ sound from the spectrogram and oscillogram. In addition, it was possible to determine the duration of the /r/ sound and, in some cases, formant values. These results reveal variation in the production of the Finnish /r/ even among the control subjects. The word/sound position of the speech sound and the length of the sound appeared to have an effect on the realization and duration of the trill, and more vibrations occurred in longer-lasting trills. When the /r/ sound was produced as an apico-alveolar trill, the main acoustic characteristics of the speech sound were the alternating closing and opening phases (vibrations) and the lower F3 relative to the surrounding vowel environment, as already noted in a previous study. Due to the wide range of phonetic variants that might replace the /r/ sound the differences between typical and atypical /r/ productions were observed depending on the speaker in the manner of articulation, sound duration and/or the number of closing phases. In this study, it was not possible to determine the place of articulation by acoustic analysis, which is partly explained by the failure of formant analysis due to the poor quality of the test subjects' data. Thus, ultrasound data was also included in the analysis, from which it was possible to visually confirm the atypical place of articulation. These results therefore demonstrate how acoustic analysis and ultrasound analysis can supplement auditory perception and provide more qualitative and quantitative information on /r/ productions produced by children. However, it is important for the researcher to consider the typical variation in the realization of /r/ productions and the certain limitations associated with the use of both methods of analysis already at the data collection stage of the study, such as the selection of test words and number of repetitions.
