Time Perception in Patients with Multiple Sclerosis
Journal Title: The 2nd Annual Meeting of International Center for Neuroscience Research - Year 2021, Vol 2, Issue 1
Abstract
Time perception is how someone perceives time, which is not necessarily the same as what clocks show. It can be either how someone perceives time intervals between two consecutive events, recognizing a stimulus duration, or even learning a rhythmic movement. It plays a crucial role in our daily activities, like moving, word spelling, natural body rhythms, and sensory information processing. Time perception alteration is frequently reported in different neurological conditions. Multiple sclerosis (MS) causes various cognitive problems for individuals but the information about how this neurodegenerative disease may affect time perception domains is rare. In this study, we aimed to investigate the domains of time perception involvement in MS. Two groups of participants (MS: n=27(8 men, 19 women), mean age=32.87; control: n=30 (10 men, 20 women), mean age=27.57) were asked to perform quadruplet time perception tasks designed in Inquisit 6 (30 days free trial version) software which consist of time estimation, duration discrimination, temporal reproduction, and paced motor timing. The time estimation (p< 0.01) and duration discrimination scores (p<0.001, in 100 milliseconds interval; p<0.05, in 1000 milliseconds interval) tasks in MS group were significantly higher than control group. Although there were no significant differences in the temporal reproduction task between the 2 groups, men showed higher scores than women in MS group (p<0.05, in 2000 and 3000 milliseconds interval; p<0.001, in 4000 milliseconds interval). Tempo matching in sensory-motor synchronization in paced motor timing test was significantly different between MS and control groups in 2000 milliseconds (p<0.0001) and 4000 milliseconds (p=0.0002). A remarkable relation between education and time estimation task score (p<0.05 and R= -0.2747) was revealed. The results can support the direct effect of level of education on the time estimation ability in both control and MS group.
