Effects of Baby Schema and Mere Exposure on Explicit and Implicit Face Processing

Area of Science:

• Social Psychology
• Cognitive Neuroscience
• Multicultural Studies

Background:

• Perceptions of ethnic in-groups versus out-groups significantly impact societal well-being.
• The Mere-Exposure Effect (familiarity breeds preference) and Baby Schema (infant features evoke caregiving) influence face perception.
• Understanding implicit physiological responses to diverse faces is crucial in multicultural contexts.

Purpose of the Study:

• To investigate the role of the Mere-Exposure Effect and Baby Schema in implicit physiological responses to in-group versus out-group infant and adult faces.
• To examine gender differences in these responses.
• To compare implicit physiological measures with explicit attitude reports.

Main Methods:

• Study 1: Measured pupillary diameter in 62 Caucasian participants viewing Caucasian and Chinese infant and adult faces.
• Study 2: Recorded electroencephalography (EEG) brain waves in 38 Caucasian participants viewing the same faces.
• Both studies included explicit attitude questionnaires.

Main Results:

• Females showed universal attention to infant faces (Baby Schema effect); males showed this for out-group infants only.
• Males exhibited greater left posterior-parietal alpha activation to out-group than in-group adult faces (Mere-Exposure Effect).
• Lower Baby Schema sensitivity to in-group infants correlated with greater attention to out-group infant faces (Mere-Exposure Effect).

Conclusions:

• Sensitivity to in-group infants can moderate perceptions of both in-group and out-group infant faces.
• Gender and Baby Schema effects modulate implicit face processing, often diverging from explicit reports.
• Differential face processing may occur at a non-conscious level, highlighting the complexity of intergroup relations.
