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.

Actor-Observer Effect

Actor-Observer Effect

The actor-observer effect, a cognitive bias closely linked to the fundamental attribution error, refers to the tendency for individuals to attribute their behavior to external, situational factors while explaining others’ behavior in terms of internal, dispositional traits. This asymmetry in attribution significantly influences social perception and judgment.Cognitive Mechanisms Behind the EffectTwo primary psychological mechanisms contribute to the actor-observer effect: differences in visual...

Social Proof

Social proof is a form of persuasion based on comparison and conformity. People compare their behavior and actions to what others are doing and will change to conform to do what their peers do.

Stereotype Content Model

Stereotype Content Model

The Stereotype Content Model (SCM) was first proposed by Susan Fiske and her colleagues (Fiske, Cuddy, Glick & Xu, 2002; see also Fiske, 2012 and Fiske, 2017). The SCM specifies that when someone encounters a new group, they will stereotype them based on two metrics: warmth—or that group’s perceived intent, and how likely they are to provide help or inflict harm—and competence—or their ability to carry out that objective. Depending on the warmth-competence categorization, a person will feel...

Longitudinal Studies

Longitudinal Studies

Longitudinal studies are also widely used in other medical and social science fields. For instance, in cardiovascular research, they can monitor patients' health over decades to identify risk factors for heart disease, such as high cholesterol or smoking, and evaluate the long-term effectiveness of preventive measures. Similarly, in mental health studies, researchers might follow individuals from adolescence into adulthood to understand the development and progression of conditions like...

Area of Science:

Social Psychology
Sociology

Background:

Prejudice reduction is a key goal in social psychology.
Understanding the longitudinal relationship between intergroup contact and prejudice is crucial.

Purpose of the Study:

To investigate the longitudinal effects of intergroup contact on prejudice.
To validate self-report measures of intergroup contact using observer ratings.
To examine individual changes in intergroup contact and prejudice over time.

Main Methods:

Cross-lagged panel design with two samples (young adults and their friends).
Validation of self-report intergroup contact measures with observer ratings.
Latent change modeling to analyze changes in contact and prejudice.

Main Results:

Self-reports and observer ratings of intergroup contact were highly correlated, validating the measures.
Significant cross-lagged effects showed intergroup contact predicting lower prejudice.
Higher initial intergroup contact predicted greater subsequent prejudice reduction.

Conclusions:

Intergroup contact is a significant predictor of prejudice reduction over time.
Individual trajectories of change in contact and prejudice exist.
The findings support the use of self-report measures for intergroup contact in longitudinal studies.
