A thesis is an aptitude test for students. The approval of the thesis is proof that the student has sufficient research and reporting skills to graduate but does not guarantee the quality of the research and the results of the research as such, and the thesis is therefore not necessarily suitable to be used as an academic source to refer to. If you would like to know more about the research discussed in this thesis and any publications based on it, to which you could refer, please contact the supervisor mentioned.
Abstract
Our interaction with the world depends on our ability to process temporal information, which is a key component of human cognition that directly impacts decision-making, planning, and prediction of events. Visual information plays a crucial role in shaping our subjective perception of time, and even brief interruptions such as those caused by eye blinks, can disrupt the continuity of our perception and alter how we estimate durations. The purpose of this study was to investigate the relationship between spontaneous eye blinks and time perception by using a temporal bisection task. Particularly, we focus on how blinks preceding stimulus presentation impact the perceived duration of that stimulus. The results from fitting a generalized linear mixed-effects model revealed that blinking can influence duration estimation. Specifically, the presence of a single blink before the stimulus presentation had a significant effect on subjective time perception, participants were more likely to categorize the duration as shorter compared to when they did not blink. In contrast, two or more blinks before stimulus presentation did not have a significant effect compared to not blinking. This study emphasizes the subtle and complex interaction between the suppression of visual input and the perception of stimulus duration. Keywords. time perception, spontaneous eye blinks, temporal bisection task
