The availability versus the use of partial information: multiple levels of selective processing between perception and action.
Temporal overlap of cognitive processes occurs when partial information about a stimulus activates associated responses before the stimulus has been fully identified. Recent evidence obtained with psychophysiological measures suggests that such overlap sometimes does, and sometimes does not occur. In this contribution, we argue that in order to understand why, we have to distinguish between selection of partial information for perception and selection of partial information for control over activation of responses. We discuss several mechanisms and factors that may modulate the temporal overlap of mental processes because they selectively influence the perceptual availability or the use of partial information.
