Is the Other-Race Effect in Working Memory Due to Attentional Refreshing?

Area of Science:

• Cognitive Psychology
• Social Psychology
• Neuroscience

Background:

• The other-race effect (ORE) describes poorer recognition of faces from different ethnic groups compared to one's own.
• This effect is often attributed to familiarity, suggesting better memory for own-race faces.
• Attentional refreshing, a working memory mechanism, has been proposed as a potential mediator of the ORE.

Purpose of the Study:

• To investigate whether attentional refreshing underlies the other-race effect in working memory.
• To test if own-race faces are refreshed more efficiently than other-race faces within working memory.

Main Methods:

• Two experiments utilized complex-span and Brown-Peterson paradigms to assess working memory performance.
• Face ethnicity (Caucasian vs. East-Asian) was manipulated alongside cognitive and memory load.
• Participants were Caucasian young adults, and performance was measured by recall accuracy.

Main Results:

• Results from both experiments were inconsistent with the hypothesis that attentional refreshing mediates the other-race effect.
• No evidence was found to support the idea that own-race faces are refreshed more efficiently than other-race faces.
• The findings suggest attentional refreshing does not explain the other-race effect in working memory.

Conclusions:

• Attentional refreshing does not appear to be the mechanism driving the other-race effect in working memory.
• The study challenges the notion that faces are maintained in working memory as a whole through attentional refreshing.
• Further research is needed to explore alternative mechanisms underlying the other-race effect.
