Abstract

Preparing for a task switch reduces but does not eliminate behavioral switching cost. Converging evidence from cognitive, functional neuroimaging, neuropathology, and aging research indicates that (a) cost is reduced by preparation and (b) remaining (residual) cost represents distinct processes, with residual cost uniquely related to prefrontal functioning. De Jong (2000) claimed that residual cost reflects a failure to engage in advance task preparation in some trials. We found that strongly encouraging advanced preparation by withdrawing the cues indicating which task to execute did not affect residual cost. The results support the claim that residual cost is associated with updating response-related information in working memory (Meiran et al., 2000), taking place in the prefrontal cortex.
