Abstract:
Exogenous and endogenous response priming
were investigated by comparing performance on
stimulus-response compatibility (SRC) and re-
sponse-effect compatibility (REC) tasks using a
repeated measures design. In the SRC task, par-
ticipants made finger taps at high or low locations
in response to centrally presented visual stimuli
paired with high- or low-pitched tones. In the
REC task, the tones were triggered by responses
instead of being presented with the visual stim-
uli, and hence effects of REC on response times
reflect the anticipation of forthcoming tones. Re-
sults indicated that response times were shorter
with compatible mappings between tones and
responses than with incompatible mappings in
both tasks. Although these SRC and REC effects
did not differ reliably in magnitude, they were
uncorrelated across participants. Thus, although
exogenous and endogenous response priming
may be functionally equivalent at the level of the
group, it is unclear whether this is the case at
the level of the individual.
