Abstract
Withholding an action plan in memory for later execution can delay execution of another action if the actions share a similar (compatible) action feature (i.e., response hand). Wiediger and Fournier (2008) found this phenomenon, termed compatibility interference, for reaching responses based on stimulus detection to a stimulus location at 17 with the left hand, but not the right hand. The current study investigated whether this result was due to hemispheric differences in the cognitive control of visually-guided responses or whether differences in the cognitive control of action based on hand preference. A sample of left and right hand preferring participants planned and withheld a sequence of keypress responses (with their right or left hand), according to the identity of a stimulus (Stimulus A), and then immediately executed a visually guided action (touch response) to a second stimulus (Stimulus B) at 15 , 35 , and 54 to the left and right of the body midline based on its location. In contrast to Wiediger and Fournier, CI was not found for responses at 15 and instead a facilitation of compatible responses was found for responses at 35 and 54 for left hand preferring participants and at 54 for right hand preferring participants. These results suggest that the reach response in the current study did not rely on short-term memory to select the appropriate response and was facilitated by compatible response plans held in memory when the reaching response was directed to more lateral stimulus locations.
