Stereotypes, Prejudice, and Discrimination

Stereotypes, Prejudice, and Discrimination

Humans are very diverse and although we share many similarities, we also have many differences. The social groups we belong to help form our identities (Tajfel, 1974). These differences may be difficult for some people to reconcile, which may lead to prejudice toward people who are different. Prejudice is a negative attitude and feeling toward an individual based solely on one’s membership in a particular social group (Allport, 1954; Brown, 2010). Prejudice is common against people who are...

Surveys

Surveys

Often, psychologists develop surveys as a means of gathering data. Surveys are lists of questions to be answered by research participants, and can be delivered as paper-and-pencil questionnaires, administered electronically, or conducted verbally. Generally, the survey itself can be completed in a short time, and the ease of administering a survey makes it easy to collect data from a large number of people.

Summary

Racial identification influences brain activity in social perception. Stronger identification with one's race correlates with distinct neural responses to ingroup versus outgroup members.

Area of Science:

Neuroscience
Social Psychology
Cognitive Science

Background:

Racial identification impacts self-concept and empathy.
Neuroimaging studies link the default network to self-referential and empathic processing.
The effect of racial identification on neural processing of social information is not well understood.

Purpose of the Study:

To investigate how racial identification influences neural responses during social perception.
To examine differences in brain activity between African American and Caucasian American individuals based on their racial identification.

Main Methods:

Functional magnetic resonance imaging (fMRI) was used to measure brain activity.
Participants included African American and Caucasian American individuals.
Neural responses to viewing ingroup versus outgroup members were analyzed.

Main Results:

Degree of racial identification predicted activity in cortical midline structures of the default network when viewing racial ingroup members.
Racial identification also predicted activity in the medial temporal lobe subsystem of the default network when viewing racial outgroup members.
Findings indicate differential neural processing based on the strength of racial identification.

Conclusions:

The strength of racial identification is associated with differential neural processing of social information.
These findings suggest that racial identification modulates how individuals understand and respond to others within and outside their racial group.
This research highlights the neural underpinnings of social perception influenced by racial identity.
