Μελέτη χρονικής αντίληψης μέσω αναπαραγωγής οπτικών και ακουστικών διαστημάτων
Translated title:
Study of time perception through the reproduction of visual and auditory intervals
Summary:
Time perception is a significant brain function which helps the individual to
navigate into time and space. Until now, it hasn’t been found which brain mechanism
is responsible for time perception, which we will investigate in this study. For this
purpose, 12 participants were chosen, 6 men and 6 women (to examine the impact of
the factor of sex), which performed the temporal reproduction task. The aim of this
study is to investigate how much participants have different perception in lengths, short
(200-1000ms) and long (1200-2000ms), which come from visual modality in
comparison to auditory modality and when the delay time (between presentation and
reproduction phase) is short (3s.) in relation to when its long (6s.). The results showed
that participants had better performance in short lengths of visual and auditory
modalities. It was found also, higher performance in short delay time, only in auditory
modality. Participants seem to overestimate short lengths and underestimate long
lengths of auditory stimulations while they underestimate all the lengths of visual
stimulations, except from the shortest length of 200ms, which is constantly
overestimated in both modalities. Men and women showed same performance in the
tasks. Further investigation, by increasing the amount of sample, by extending the upper
time limits and by importing brain electrophysiology would strengthen the study to
understand this complicated mechanism of time perception.
