    The pressing challenge of climate change and its uncertainties require effective communication to engage mitigation efforts. Data visualizations enable presenting complex data to layperson and professionals. People’s perception, however, seems to be affected by their motivations, and uncertainty in data. This study investigates the influence of prior beliefs and uncertainty representation on climate-aware people’s interpretation of climate data visualizations. In an online experiment, participants estimated the correlation of variables displayed in scatterplots. The plots were labelled either with meaningful or abstracted variables, and either included uncertainty representation or not. Participants also indicated how much they believed the meaningful variables to be correlated. When a correlation triggered their beliefs, participants estimated higher correlations than when they did not have beliefs about the displayed data. The representation of uncertainty alone did not influence the estimation performance. When participants had beliefs about a correlation and uncertainty was represented in the plot, participants’ estimation was higher than in the other conditions and the least accurate. The findings suggest that people’s interpretation was biased by their prior beliefs, especially in combination with uncertainty representation. This might be explained by prior beliefs guiding participant’s attention to features of the visualization supporting their views. This biased perception seems to affect their interpretation. Uncertainty representation might increase the bias by expanding the range of possible interpretations, potentially prompting people to rely on their prior beliefs more strongly.

    Research on the interaction of the Amuric languages (referred to as “Nivkh” or “Ghilyak” when regarded as a single language) with the Tungusic languages was initiated by Grube (1892). His focus on loanwords has been the object of study until the present day. Recently, Janhunen (2010: 292, 296; 2016: 23) has suggested that contact between the two families already started between their ultimate ancestors: Pre-Proto-Amuric and Proto-Tungusic. This thesis investigates whether some of the lexical parallels proposed by earlier research belong to this period. As the thesis is written from the perspective of language contact, the parallels are regarded as the result of borrowing instead of inheritance. The distinction between these two modes of transmission formed the theoretical basis for the methodology that was employed. To prove ancient contact, it had to be shown that the Amuric and Tungusic languages inherited their shared lexemes from their respective ancestors and that these ancestors may have borrowed from each other. As the methodology relied on the literature on Amuric and Tungusic historical phonology, an overview of this topic is also included. First, fifty parallels were drawn from those listed in previous research. These could be reconstructed to Proto-Amuric and Proto-Tungusic using the Comparative Method and thus could have been inherited from them or an earlier ancestor in the case of Proto-Amuric. Additionally, they exhibited phonological similarities that could reasonably be expected from borrowing between Pre-Proto-Amuric and Proto-Tungusic. Afterwards, a direction of borrowing had to be established, the principal evidence of borrowing. For that purpose, nine criteria were developed. These criteria considered morphology, diachronic and synchronic phonology, extent of attestation, semantics and extra-linguistic factors. Finally, the data was separated into older and younger strata, since in the selection phase only the Proto-Amuric stage was considered, while the target was Pre-Proto-Amuric. These layers were classified on the basis of phonological developments. For most of the fifty parallels the direction of borrowing could be determined. In this stage of analysis, fifteen of them were ultimately dismissed as recent or doubtful. The remaining thirty-five were examined for properties that could have resulted from the sound changes that followed Pre-Proto-Amuric that were proposed in earlier research. Ultimately, it could only be proven that the absence of vowels in non-initial syllables was a property characteristic of ancient lexemes in the Amuric lineage. Consequently, although a substantially old stratum of Amuric-Tungusic parallels was found, further research is needed to show that any of them date to Pre-Proto-Amuric and Proto-Tungusic times.

    Statistical learning (SL) is a set of cognitive mechanisms which allow an organism to subconsciously pick up recurring patterns from its environment. While research in this field has flourished over the past decades, its relationship with multilingualism remains unclear. Our goal is to estimate the extent of this relationship by comparing individual language skills with the performance in a statistical language learning (SLL) task. For this purpose, we conducted an online experiment to collect information about the participants' linguistic background and to test their SL ability via a Statistically Induced Chunking Recall (SICR) task. Additionally, visual linguistic stimuli were generated to examine how the phonotactic rules of the participants' native tongue would impact SL. In particular, we tested how violating vowel harmony in Finnish affected the performance of participants with different degrees of multilingualism. To measure multilingualism, we created the Multilingualism Score (MS), a multifactorial index designed to gauge one's multilingualism level and to analyse its relationship with the performance in the SICR task. Our results exhibit positive correlation between these two factors, suggesting that multilingualism and SLL are significantly correlated. We also observed overall lower performance associated with the violation of vowel harmony. However, we were not able to establish a clear connection between multilingualism and the performance gap.

    This thesis investigates the realisation of tone in dialects of Southern Angami, a language of Tibeto-Burman family spoken in the state of Nagaland, North-East India. The audio recordings of native speakers are analysed to determine how the tones differ in pitch movement patterns, accounting for context and dialect variation. The research questions concern the significance of pitch contours and duration in a level tone system, as well as tone unit interaction. It was concluded that the fundamental frequency is the main determining factor, and neither pitch contour nor duration have a more prominent effect than pitch value; however, it is possible that duration plays a role in discerning tones 2 and 3, and a pitch curve is a consistent feature of tones 1 and 4. No significant difference was found in tone systems of Jotsoma and Kigwema.

    This thesis examines the typology and stability of evidentiality in contact settings. The goal is to estimate the stability of evidentiality in different contact scenarios, and to find whether evidential structures are more likely to change in language contact situations than to remain stable. Furthermore, this study aims to develop methodology to approach the typology of evidentiality to examine its contact effects in the first place. Earlier research has described evidentiality as an unstable feature that diffuses easily in contact situations, but systematic research examining evidentiality in multiple contact settings and its stability in contact is yet lacking. Moreover, evidentiality has been studied widely, but there is no previous typological approach on evidentiality or on its contact effects that would be suitable for the purposes of this thesis. This study takes a typological approach to the study of evidentiality and language contact. The examination of contact effects is based on six sampling units of three-language sets across the globe, wherein contact effects are estimated on an external benchmark. The collected linguistic data from the sampling units was analyzed into logical outcomes of contact and turned into probability distributions. This finally resulted in the aggregated probability of convergence. The probability of convergence is contrasted to the stability of evidentiality and in that continuum this study estimates how likely it is that evidentiality has been affected due to contact. Furthermore, this thesis focuses on finding a suitable way to approach the first research goal and therefore presents a typological approach on evidentiality and defines grammatical evidentiality. The primary results of this study suggest high probability of convergence and evidentiality seems to be an unstable linguistic domain that diffuses easily. These findings were further contrasted to some other linguistic domains indicating that evidentiality is among the most unstable domains. This study also suggests that the semantic properties of evidentiality are more unstable than the morphological ones. The findings also highlight the sensitivity of the methodology, and these limitations are demonstrated and reflected upon.
