Module 41: Group Differences and Intelligence

Learning Targets

• Analyze gender, racial, and ethnic differences in mental ability scores.

• Evaluate test bias and stereotype threat.

Group Differences in Intelligence

• Gender Differences

  • Females: Better spelling, verbal fluency, and emotional detection.

  • Males: Better spatial ability and complex mathematics; exhibit greater score variability.

  • Variations often reflect societal expectations.

• Racial and Ethnic Differences

  • Score variations linked to environmental factors (e.g., socioeconomic status, education) rather than heredity.

Intelligence Test Bias

• Cultural Influence: Tests may reflect environmental/cultural experiences rather than statistical predictive bias.

• Stereotype Threat: Anxiety about confirming negative group stereotypes can impair test performance.

  • Mitigation: Self-affirmation and diverse teaching strategies help reduce effects.

Conclusion

• Tests are objective tools but must be interpreted alongside cultural contexts and individual potential beyond numerical scores.
