This paper examines whether stereotype threat might
reduce performance by imposing demands on the
phonological component of the working memory system. If stereotype threat produces worries and concerns about
the task at hand, then these worries might interfere
with the part of working memory that is responsible for
storing task-relevant verbal information. In
Experiment 1, male and female math-identified
participants completed easy and difficult tasks
involving modular arithmetic under stereotype threat
(with the study described as assessing "why men are
generally better than women at math") or no stereotype
threat (with the study assessing "why some people are
better at math than are others"). Performance was
poor only in the stereotype threat condition and only on
problems that were difficult (i.e.,
horizontally-presented items that place high demands on
working memory). In Experiment 2, participants completed
math items that were high and low in the demands they
place on working memory, and items were solved either as
a single task or concurrently with a second task
designed to reduce available phonological resources. Only completing demanding math problems reduced
performance on the secondary task. Experiments 3A
& 3B took advantage of this finding to assess the
consequences of inducing stereotype threat. Highly-demanding math problems were less likely to be
correctly answered under stereotype threat, and poor
performance was accompanied by more self-reported
task-related thoughts and worries. Experiment 4
showed that practice on demanding math items can
attenuate stereotype threat effects, suggesting that
practice reduces the demands of task performance on
working memory capacity. Experiment 5 provided
further evidence that stereotype threat affects the
phonological component of working memory by
demonstrating that performance on later unrelated
verbal, but not on spatial, tasks were negatively
affected following stereotype threat in math. These results show that stereotype threat undermines
performance on tasks that are especially reliant on
phonological resources and affects performance on
subsequently encountered tasks that rely on those same
resources. Moreover, practice and proceduralization can reduce the negative consequences
of stereotype threat by reducing the need of
phonological resources in problem solution.
