Aims The goal of this paper is to examine the peripheral factors of stimuli in Samuel Tuhkanen's pro gradu thesis experiment and evaluate the possibility of improving the experiment by manipulating the peripheral factors. Methods The peripheral factors of stimuli in Tuhkanen's experiment have been explored in light of earlier literature on peripheral vision. The different factors have been evaluated on how they affect the results of the experiment as well as how the experiment could be changed depending on these factors. Results and conclusions Motion, salience, color, shape, brightness, crowding and placement factors were identified as irrelevant because they are constant in the experiment. Size, complexity, contrast and orientation were identified as being useful for manipulating the results of the experiment. Of these factors size and contrast were found the best ways of manipulating the difficulty of the experiment.
