Resum
Switching from one task to another usually produces a cost in performance. This switch has been shown to interact with repetition priming. In the present study we use this interaction to investigate the response representation involved in task switch. We find an interaction between switch cost and repetition priming even when the responses required in the two tasks are not the same but are made with corresponding fingers of different hands. We conclude that an abstract response representation, based on RIGHT-LEFT action codes, is responsible for the effect. Besides, response representation changes, as preparation time increases, from more physical, effector-related action codes to more abstract ones.
