Self-awareness of face recognition abilities, measured by the Prosopagnosia Items (PI-20), is strong in individuals with very poor or excellent face recognition skills. However, this insight is lacking in those with typical face recognition performance.
Area of Science:
- Cognitive Psychology
- Neuroscience
- Human Perception
Background:
- The 20-Item Prosopagnosia Items (PI-20) is a self-report tool for assessing face recognition and aiding prosopagnosia diagnosis.
- Previous studies indicate users generally possess moderate to strong insight into their face recognition capabilities.
- It is unclear if this self-insight is consistent across the entire spectrum of face recognition abilities.
Purpose of the Study:
- To investigate the consistency of self-reported face recognition insight across different performance levels.
- To examine the relationship between self-assessment (PI-20) and objective testing (Cambridge Face Memory Test Chinese - CFMT-Chinese).
Main Methods:
- Utilized the Mandarin version of the PI-20 questionnaire.
- Administered the Cambridge Face Memory Test Chinese (CFMT-Chinese) for objective face recognition assessment.
- Analyzed the correlation between PI-20 scores and CFMT-Chinese performance.
Main Results:
- A moderate negative association was observed between the PI-20 and CFMT-Chinese scores.
- This correlation was significant for individuals with exceptionally low or high face recognition abilities.
- The association between self-reported insight and objective performance was absent in the typical performance range.
Conclusions:
- Self-awareness of face recognition ability is not uniform across all performance levels.
- The PI-20 may be a useful diagnostic aid, particularly for identifying individuals at the extremes of face recognition ability.
- Further research is needed to understand the nuances of self-perception in face recognition deficits and typical performance.
