More-errup ts is r nd of tions, ticipants respond faster on congruent trials, as compared following trial. Likewise, increased connections improve task performance when a task is repeated but hinder task performance when the task changes, causing the modula-tion of the switch cost. Although the hypothesis that conflict enhances associa-tions is fairly recent, it has been long known that rewar
