Abstract: We translated and validated the Traditional Chinese version of the 20-item Prosopagnosia Index in five studies (total n = 401) involving Mandarin-speaking adults in Taiwan. The results demonstrate strong internal consistency and construct validity, as shown by significant correlations with tasks in face memory, within-person identification, and facial realness judgment.
