초록

Purpose: This study was designed to determine the correlation between faster response time and functional activities of brain regions during cognitive time management.
Methods: Twelve healthy subjects participated in this experiment. Subjects performed the serial reaction time task (SRTT), which was designed by the Superlab program, during fMRI scanning. When the ‘asterisk’ appeared in the 4 partition spaces on the monitor, the subject had to press the correct response button as soon as possible.
Results: fMRI results showed activation of the left primary sensorimotor cortex, both premotor areas, the supplementary motor area, posterior parietal cortex and cerebellum. There were significant correlations, from moderate to strong, between faster reaction time and BOLD signal intensity in activated areas.
Conclusion: These results suggest that motor skill learning to be needed cognitive time management is associated with greater activation of large scale sensorimotor networks.
