Abstract
Psychophysiological measures were used to compare the response preparation and response execution processes of modified versions of F. C. Donders's (1868/1969) classic simple, go/no-go, and choice reaction time tasks. On all measures, differences between tasks were minimal prior to test stimulus onset. supporting the idea of equivalent motor preparation for the 3 tasks. In addition, the psychophysiological measures indicated that the time from the onset of motor processing to the keypress response was also approximately constant across tasks. These results support the assumption that the mean duration of motor processes can be invariant across simple, go/no-go, and choice tasks, at least for the present modified versions of these tasks. The findings emphasize the utility of psychophysiological measures for both examining preparatory processes preceding stimulus onset and for localizing effects on reaction time.Keywords
