Abstract
Left-right confusion commonly occurs in neurologically intact individuals. This study aimed to investigate the real-life individual differences in left-right confusion among healthy Japanese young adults. The effects of gender and handedness were also examined in a balanced sample with similar numbers of left- and right-handed and female and male participants. Half of the 128 participants (32 of 64 males; 32 of 64 females) were left-handed. Participants were administered a self-rated confusability questionnaire and the Money Road-Map Test (MRMT). In the self-rated questionnaire, females reported a stronger degree of confusability. Although the main effects of handedness, the main effect of gender, and their interaction were non-significant in terms of the accuracy performance of the MRMT, there was a male-dominated gender difference in completion time. The results of this study confirm that there are individuals who are neurologically intact, but who show extreme left-right confusion—both subjectively and objectively. This issue must be understood in terms of promoting diversity, equity, and inclusion in the broader community.
