The effect of context on responses to racially ambiguous faces: changes in perception and evaluation

Area of Science:

• Social Psychology
• Cognitive Neuroscience
• Racial Perception

Background:

• Individuals with features of multiple racial groups are susceptible to contextual influences on racial perception.
• External cues can shape how we perceive and judge individuals of ambiguous racial background.

Purpose of the Study:

• To investigate how extrinsic race-label cues influence racial perceptions and evaluative associations.
• To examine the impact of race labels on neural responses related to racial perception.

Main Methods:

• Used behavioral measures to assess implicit associations with prototypical and racially ambiguous faces.
• Employed electroencephalography (EEG) to record neural responses (P200, N200) to faces with different race labels.
• Manipulated extrinsic race-label cues presented with racially ambiguous faces.

Main Results:

• Race labels changed implicit associations, with Black-labeled faces eliciting more negative associations than White-labeled faces.
• Neural responses were similar for prototypical and ambiguously-raced faces when assigned the same race label.
• Specifically, Black-labeled faces showed larger P200 and smaller N200 amplitudes compared to White-labeled faces.

Conclusions:

• Racial perception is not fixed and can be significantly altered by external contextual cues.
• External race labels influence both implicit evaluative associations and early neural processing of faces.
• These findings highlight the dynamic nature of racial categorization and its impact on social cognition.
