Implicit race attitudes modulate visual information extraction for trustworthiness judgments.

Area of Science:

• Social Psychology
• Cognitive Neuroscience
• Perception

Background:

• Racial prejudice impacts social cognition and face processing.
• Implicit racial bias can influence perceptions of trustworthiness and criminality in other-race faces.
• The effect of implicit racial bias on low-level perceptual mechanisms like spatial frequency (SF) extraction remains unclear.

Purpose of the Study:

• To investigate whether implicit racial bias modulates spatial frequency (SF) extraction during the trustworthiness judgment of other-race faces.
• To determine if distinct SF processing patterns exist for own-race versus other-race faces.
• To examine the relationship between the level of implicit racial bias and SF reliance in face perception.

Main Methods:

• Participants judged the trustworthiness of White and Black faces.
• Spatial frequency (SF) content of faces was manipulated.
• Implicit Association Test (IAT) was used to measure implicit racial bias.

Main Results:

• Own-race faces were processed using lower spatial frequencies (SF) compared to other-race faces.
• Higher implicit racial bias was associated with a greater reliance on low SF for White faces.
• This pattern of increased low SF reliance for own-race faces was less pronounced or absent for Black faces.

Conclusions:

• Implicit racial bias influences fundamental perceptual processes in face evaluation.
• Racial bias can alter the reliance on coarse visual information (low SF) when judging trustworthiness, particularly for own-race faces.
• These findings highlight the pervasive impact of implicit bias on visual perception and social judgment.
