[Simon effect and relative position of the stimuli].
The so-called Simon effect can be determined (a) by a natural tendency to respond towards the source of stimulation, or (b) by a comparison between the encoding of the position of the stimulus and the encoding of the position of the effectors producing the response. Twelve subjects performed a manual choice between two visual stimuli in the same visual hemifield. The results of the experiment supported hypothesis (b).
