The Moderation Effect of Self-Enhancement on the Group-Reference Effect

Area of Science:

• Social Psychology
• Cross-cultural Psychology
• Cognitive Neuroscience

Background:

• Previous research indicates faster responses and better memory for in-group traits, especially among ethnic minorities.
• The influence of trait valence on this in-group preference effect remains under-explored.

Purpose of the Study:

• To investigate how ethnic identity salience and trait valence impact the group-preference effect.
• To examine processing advantages for positive versus negative traits within and between ethnic groups.

Main Methods:

• The study involved Han Chinese in a Tibetan-dominant area and Tibetan participants in a Han-dominant area.
• Ethnic identity salience was measured two weeks prior to the experiment.
• A group-reference effect (GRE) paradigm with three encoding tasks was employed.

Main Results:

• Both groups exhibited faster processing of positive traits than negative traits when evaluating their own group.
• No significant difference in processing positive versus negative traits was found for out-group evaluation or font judgment tasks.
• A pervasive processing advantage for in-group positive characteristics was observed.

Conclusions:

• Self-enhancement motivation appears to moderate the group-preference effect.
• Ethnic identity salience may not be a necessary condition for the group-preference effect.
