| Outline of Final Research Achievements |
Directing attention to movement outcome (external focus, EF) had the advantages compared to directing attention to body movement (internal focus, IF) in motor learning tasks. In this study, to explore the neural basis associated with individual optimal attentional strategy, we recorded the neural activity in prefrontal area by using functional near-infrared spectroscopy. Fifty-six participants performed motor learning task with arm-reaching movements under IF and EF conditions. Although 29 participants showed better motor learning effect under IF condition, the others showed opposite trend. Subsequently, we measured the neural activities in prefrontal area during visuomotor task. We found that the left dorsolateral prefrontal cortex and left frontopolar cortex had individual differences associated with the optimal attentional strategy. These results suggest that the left prefrontal area reflect individual cognitive abilities to enhance motor learning.
