The 20-item prosopagnosia index (PI20) was developed for assessing congenital prosopagnosia, which is characterized by severe facial recognition deficits in the absence of any obvious neurological deficit. We aimed to develop a Japanese version of the PI20 (PI20-J) scale and evaluate its validity and reliability. In study 1, we confirmed the internal consistency, test-retest reliability, and concurrent validity of the scale. In study 2, we examined the relationships between PI20-J score and facial recognition performance and found a moderate correlation between them. In study 3, we examined whether the PI20-J score is related specifically with facial recognition performance, or with general object recognition performance. We found that participants with a high PI20-J score showed weaker facial recognition performance than those with a low PI20-J score. In contrast, the object recognition performance did not depend on the score. Our results suggest that the PI20-J score is related specifically with facial recognition performance. We conclude that PI20-J is highly reliable and valid as a self-reported measure for congenital prosopagnosic traits.

The quantitative assessment of footedness is required in various fields, such as psychology, neuroscience, sports science, medicine, and medical practice. While the Waterloo Footedness Questionnaire-Revised (WFQ-R) is the most accepted measurement of footedness, a Japanese translation of the WFQ-R is still not available. In the present study, we developed a Japanese translation of the WFQ-R and tested its validity and reliability. Five hundred and forty-seven university students (153 women) were administered the questionnaire online. Seventy-six of the 547 participants were tested twice to assess the test-retest reliability. We found that the Japanese translation of WFQ-R had a two-factor structure (manipulation and balance), as its developer proposed, and high internal consistency and test-retest reliability. These results suggest that the Japanese translation of the WFQ-R is a valid and reliable measure of footedness.
