Deficits in other-race face recognition: no evidence for encoding-based effects.

Area of Science:

• Cognitive Psychology
• Social Psychology
• Neuroscience

Background:

• The other-race effect (ORE) is a phenomenon where individuals are less accurate at recognizing faces of a different race compared to their own.
• While typically observed in long-term memory tasks, some research suggests ORE emerges early in face encoding.

Purpose of the Study:

• To investigate whether the other-race effect in face recognition is due to deficits in immediate encoding or later memory processes.
• To differentiate between perceptual encoding and retention/retrieval as sources of the ORE.

Main Methods:

• Six experiments involving over 300 participants were conducted.
• Tasks included immediate recognition, match-to-sample, and recognition with distractor tasks (trivia) during the retention interval.
• Computer-generated faces were used and validated for their efficacy.

Main Results:

• No evidence was found that the ORE reflects deficits in immediate face encoding across multiple experiments.
• Recognition performance for Asian and White faces was similar in immediate recognition tasks.
• The ORE re-emerged when target-foil similarity was decreased and the retention interval was disrupted with trivia.
• Memory for Asian faces was particularly susceptible to distraction, while White faces were recognized consistently.

Conclusions:

• The recognition deficit in the other-race effect appears to originate from deficits in memory retention or retrieval.
• Immediate perceptual processing differences do not account for the other-race effect.
• Distraction during the retention interval significantly impacts the ORE, particularly for same-race face memory.
