Abstract:

Time perception is a complex process which constitutes a base of our functioning. This process operates on different temporal levels, hierarchically ordered i.a., on milliseconds and seconds levels. The literature data indicate that the milliseconds level, may be crucial for the effectiveness of our functioning at higher temporal levels and corresponds with efficiency of our cognitive functioning. The aim of this study was to verify above-mentioned assumptions and to examine the neural correlates of time perception. In this study 109 young adults were tested. In the first part of the project (behavioural one) two groups of participants were selected, i.e., characterised by either high (WEpc) or low (NEpc) efficiency of time perception on the milliseconds level. Then, the between-groups comparisons in the efficiency of time perception on the seconds level and cognitive ability such as planning, working memory and attention were performed. In the second part of the study (neuroimaging one), the pattern of the brains structures engaged in time perception on different levels of difficulty (condition: hard, medium, easy), activated independently (the crucial areas) and dependently on individual differences in efficiency of time perception (additional areas) on the milliseconds level, were determined. The obtained results evidenced that group characterised by a high or low efficiency of time perception on the milliseconds level, showed a high or low efficiency of time perception on the seconds level, respectively. Moreover, WEpc group showed better planning, working memory and attention compared to NEpc group. Next, the frontal cortex, as well as insula were revealed as crucial areas for time perception. No additional areas related to efficiency of time perception on the milliseconds level, were determined. As the difficulty of the task was modified, the pattern of the crucial areas also was changing, i.e., in the hard and medium conditions activations in frontal areas appeared, whereas during the easy condition, we observed activations in frontal and parietal cortices as well as in cingulate cortex and insula. To sum up, the efficiency of the time perception on the milliseconds level seems to be crucial for both efficient functioning on the higher temporal levels and for our cognitive functioning. The crucial areas of the brain associated with time perception were identified; however, the activation patterns of these areas did not differ in terms of individual efficiency of time perception at the milliseconds level.
