Extending the Concept of Stereotype Threat to Social Class: The Intellectual Underperformance of Students from Low Socioeconomic Backgrounds

Students from poorer families perform worse on intellectual tasks than do other students. The authors tested the stereotype threat hypothesis as a possible explanation for this difference. Students from relatively poor backgrounds, such as members of other stereotyped groups, risk confirming a negative reputation of low intellectual ability. The authors predicted that, on a stereotype-relevant test, members of this group would experience apprehension about confirming their negative reputation and that this susceptibility to the stereotype would impair their performance. The study varied stereotype threat by manipulating the instructions accompanying the test that each participant completed. When described as a measure of intellectual ability, low socioeconomic status (SES) participants performed worse than high SES participants. However, when the test was presented as nondiagnostic of intellectual ability, low SES participants' performances did not suffer, contesting claims of SES differences in intellectual ability.
