    Description

    Inhibitory control was used to investigate independently from time processing. However, growing evidence suggested that high collinearity between these two functions. Especially, two paradoxical but co-existed phenomena in major depression (MDD) patients revealed this possibility. Slow flow of time perception is one main symptom and leads slow reaction times because of abnormal time perception. In contrast, MDD also have low inhibitory control. Responses to stimulus were too fast to withdraw their responses. A hypothesis accounted for slow reaction times cannot explain the existence of low inhibitory control and vice versa. An altered temporal process was emerged and has high potential to account for these paradoxical phenomena. To address this question, I proposed this study to uncover the neural correlates of temporal process with an oculomotor version of foreperiod task to examine implicit temporal process and impulsive responses. Temporal process and inhibitory control could be probed within the same task. Meanwhile, EEG will be measured while performing this task to delineate the neural mechanism underlying temporal process and inhibitory control.
