The other-race effect in perception and recognition: insights from the complete composite task

Area of Science:

• Cognitive Psychology
• Social Psychology
• Neuroscience

Background:

• The other-race effect (ORE) describes reduced accuracy in recognizing faces of different races compared to one's own race.
• ORE has been observed in various perceptual tasks, prompting investigation into its underlying cognitive mechanisms.

Purpose of the Study:

• To investigate whether deficits in holistic face processing contribute to the ORE in face recognition.
• To differentiate the cognitive processes involved in face recognition versus holistic face perception.

Main Methods:

• Employed recognition tests and the composite task paradigm with White and Chinese participants.
• Assessed performance on both own-race and other-race faces across experimental conditions.
• Measured participants' ability to selectively attend to facial features while ignoring irrelevant information.

Main Results:

• Significant own-race effects were observed at the group level for face recognition tasks.
• No significant own-race effects were found in the composite task, indicating ORE is not universally present across all face perception measures.
• Individual difference analyses did not support the hypothesis that impaired holistic processing underlies the ORE in recognition.

Conclusions:

• The other-race effect in face recognition is not driven by the same holistic processing mechanisms measured by the composite task.
• Findings suggest distinct cognitive processes underlie face recognition accuracy and holistic face perception, particularly concerning own- versus other-race faces.
