Response Coding and Visuomotor Transformation in the Simon Task: The Role of Action Goals
Buhlmann, Ivonne; Umilta, Carlo; Wascher, Edmund
Journal of Experimental Psychology: Human Perception and Performance, v33 n6 p1269-1282 Dec 2007
Manual responses can be defined by differing response parameters. Any of them may generate a Simon effect. For all those response parameters, the same implementation of the Simon effect (in terms of subserving mechanism) is assumed. In 3 experiments, subjects had to respond with either fingers or sticks. Temporal properties of the Simon effect changed with response parameters relevant in a task. The Simon effect for manual responses decayed. For stick responses, in which the action goal differed from the anatomical mapping of the acting hand, a sustained Simon effect was observed. However, if the action goal for stick responses was not instrumental for selecting the correct response, the Simon effect decayed. The findings are consistent with the notion of different mechanisms involved in generating a Simon effect.
