The Psychology of Stereotypes: Formation and Impact

Formation of Stereotypes

1. Social Identity Theory: Categorization of individuals into groups.
2. Conformity: Adopting beliefs to fit into a social group.
3. Illusory Correlation: Perceiving a relationship between events or behaviors where none exists.

Effects on Behavior and Cognition

• Stereotype Threat: The risk of conforming to negative stereotypes about one's social group.
• Diagnosis: Stereotyping may negatively influence clinical diagnosis and treatment outcomes.
• Memory: Stereotypes function as schemas, which can lead to memory distortion.

Case Study: Hamilton & Gifford (1976)

Aim

To investigate the illusory correlation between group size and negative behavior.

Method

• Participants read descriptions of two groups (A and B) containing positive and negative behaviors.
• Group A (Majority): Twice as many members as B; performed 18 positive and 8 negative behaviors.
• Group B (Minority): Performed 9 positive and 4 negative behaviors.
• Participants were asked to attribute behaviors to each group.

Results

• Despite the proportion of negative behaviors being identical for both groups, participants formed an illusory correlation.
• Undesirable behaviors were disproportionately attributed to the minority Group B.

Conclusion

• Distinctive information draws more attention.
• Because minority group members and negative behaviors are numerically rarer, their combination stands out, creating a false correlation.

Case Study: Steele & Aronson (1995)

Aim

To investigate the effect of stereotype threat on test performance.

Method

• African American and European American participants took a 30-minute verbal test.
• One group was told it was an articulation test; the other was told it was a laboratory task.

Results

• African Americans scored lower than European Americans when told it was an articulation test.
• When framed as a laboratory task, African Americans scored higher than European Americans.

Conclusion

• Stereotype threat significantly impacts individual performance.
• Believing in stereotypes can cause groups to underperform, effectively fulfilling the stereotype.
