The other-race effect does not rely on memory: Evidence from a matching task.

Area of Science:

• Cognitive Psychology
• Social Psychology
• Neuroscience

Background:

• The other-race effect (ORE) describes better recognition of own-race faces compared to other-race faces.
• The underlying mechanisms of ORE, whether perceptual or memorial, remain debated.

Purpose of the Study:

• To investigate whether perceptual or memorial processes primarily contribute to the other-race effect.
• To examine the role of face perception and memory in cross-racial face recognition.

Main Methods:

• A simultaneous face-matching task was employed with UK and Egyptian participants.
• Target faces were presented in upright and inverted orientations to assess perceptual processing.
• Performance was measured for own-race and other-race face matching.

Main Results:

• Participants exhibited the other-race effect, performing worse on other-race faces.
• A stronger face inversion effect was observed for own-race faces.
• Performance on own- and other-race faces was highly correlated, suggesting shared processing mechanisms.

Conclusions:

• Difficulty in perceptual encoding of unfamiliar faces significantly contributes to the other-race effect.
• Explanations for the other-race effect solely based on memory are insufficient.
• Findings have implications for forensic science and eyewitness identification.
