Understanding the role of executive control in the implicit association test: why flexible people have small IAT effects.
The goal of the present research was to investigate the role of three central-executive functions-switching of mental sets, inhibition of prepotent responses, and simultaneous storage and processing (i.e., working-memory capacity)-in accounting for method variance in the Implicit Association Test (IAT). In two studies, several IATs with unrelated contents were administered along with a battery of central-executive tasks, with multiple tasks tapping each of the above executive functions. Method variance was found to be related to the switching factor, but not to the inhibition factor. There was also evidence for a small independent contribution of the working-memory capacity factor. The findings constrain process accounts of the IAT, lending support to an account in terms of task-set switching, and they have consequences for applications.
