Temporal order judgment and simple reaction times: evidence for a common processing system.

摘要: We present a simple reaction time (RT) versus temporal order judgment (TOJ) experiment as test of the perception-action relationship. The improves on previous ones in that it assesses for first RT and TOJ trial-by-trial basis, hence allowing study two behaviors within same task context and, most importantly, association to "correct" "incorrect" TOJs. RTs pairs stimuli are significantly different depending associated TOJs, an indication perceptual motor decisions based internal response. Simulations with simplest one-system model (J. Gibbon & R. Rutschmann, 1969) using means standard deviations presented isolation yield excellent fits mean these increments when sequence moderately good classified according categories. observation point subjective simultaneity stimulus is systematically smaller than difference each pleads, however, favor distinct decision criteria perception action former below latter. For such case, race models require noise be less one pair. data show reverse state affairs. In short, simulations comply "one-system-two-decision" behaviors, while prompting further testing modeling account apparent discrepancy between ordering decisions.
