The Choke Factor

Every sports fan has vivid memories of key occasions on which a favorite team or player has 'choked' under pressure. And every student who has ever taken a standardized test knows what that kind of pressure feels like. What makes for high-pressure situations, and how do they influence performance? In the last decade such issues have been explored by social psychologists researching the phenomenon of stereotype threat. Their work shows not only that pressure can compromise performance, but that this dynamic is more common among members of negatively stereotyped social groups. Why?

The classic demonstration of stereotype threat, in a 1995 paper by Claude Steele and Joshua Aronson, emerged from a series of studies in which high-achieving African American students at Stanford completed the Graduate Record Exam (GRE) under conditions where they thought either that the test was measuring intelligence or that it was not a test of ability at all. Intriguingly, these bright students did much worse when they considered it an intelligence test.. This, the researchers argued, was because "in situations where [a negative] stereotype is applicable, one is at risk of confirming it as a self-characterization, both to one's self and to others who know the stereotype." This tendency to perform worse when conscious of being in a group stereotyped as performing poorly is what is meant by stereotype threat.

This pattern of findings has been replicated with many different groups on many different dimensions of stereotype content. The work of the University of Chicago's Sian Beilock and colleagues, reported in the latest issue of the Journal of Experimental Psychology (abstract or pdf download), follows that of many previous researchers in showing that if female students are made aware of a stereotype that men have greater mathematical ability than women, they tend to do worse on complex mathematical tasks than they do if they are not alerted to this stereotype.
