TEMPORAL IMPAIRMENT IN DEAFNESS
In this study we compared the performance of deaf and control participants under three temporal tasks: time reproduction, time production and time discrimination tasks with the same short duration (500, 1000 and 1500 ms). Moreover, participants performed the reproduction and production tasks also with longer duration (3, 4 and 5 s). Testing time perception with different methodologies allows investigating the different cognitive functions that are involved in time perception. Furthermore, we employed millisecond and second range duration to investigate a possible relationship between time perception and language dysfunction that is often presented in deaf patients. Nine deaf adults (mean age 54.98 yrs) and 9 controls (mean age 54.38 yrs) participated in the study. Significant differences were found between groups with the discrimination, reproduction and production tasks when participants judged longer durations.
