Neural signals for the detection of unintentional race bias

Article Abstract:

We examined the hypothesis that unintentional race-biased responses may occur despite the activation of neural systems that detect the need for control. Participants completed a sequential priming task that induced race-biased responses on certain trials while electroencephalography was recorded. The error-related negativity (ERN) wave, a component of the event-related potential with an anterior cingulate generator, was assessed to index neural signals detecting the need for control. Responses attributed to race bias produced larger ERNs than responses not attributed to race bias. Although race-biased responses were prevalent across participants, those with larger ERNs to race-biased responses showed higher levels of control throughout the task (e.g., greater accuracy and slowed responding following errors). The results indicate that race-biased responses may be made despite the activation of neural systems designed to detect bias and to recruit controlled processing.

Stereotype susceptibility: identity salience and shifts in quantitative performance

Article Abstract:

Two experiments were conducted to examine the positive and negative stereotypes associated with different identities that can coexist in an individual. The objective was to determine whether subtly activating different self-stereotypes would affect the quantitative performance of Asian-American women. Results indicate that the performance of Asian-American women in a mathematics test was worse when their gender identity was activated and better when their ethnic identity was activated. Findings suggest that stereotype influences performance.

Stereotypes as source-monitoring cues: on the interaction between episodic and semantic memory

Article Abstract:

A study was conducted to analyze the application of stereotypic expectancies as source cues for biographical memories. The function of stereotypes in source attributions for specific biographical events was examined. Results indicated the efficiency of stereotype use during the encoding and retrieval of social information. Findings also showed costs related to using stereotypes as source cues.
