Abstract

The purpose of this study was to investigate the correlation between differences in hand functions and brain preference in young adults. The participants were 52 right-handed, healthy adults in their 20s. Brain preference was classified as having a left-brain preference, right-brain preference, or whole-brain preference by the Brain Preference Indicator. Hand dexterity was measured by the Purdue Pegboard Test.


The difference between right- and left-hand functions was statistically significant for subjects in all brain preference types. Right-hand dexterity in those with left- and right-brain preference was significantly faster than in those with whole-brain preference, while left-hand dexterity among the three groups was not significantly different. The difference in hand dexterity between the right and left hand was not significant in all groups. This study examined the correlation between hand dexterity and brain preference type. Those in the unilateral brain preference groups showed better dexterity than those in the both brain preference group.
