采用重复测量设计，通过比较刺激-反应相容性（SRC）和反应-效果相容性（REC）任务的表现，研究外源性和内源性反应启动。在SRC任务中，参与者在中央呈现的视觉刺激与高音调或低音调配对时，手指在高或低位置轻敲。在REC任务中，音调是由反应触发的，而不是由视觉刺激呈现的，因此REC对反应时间的影响反映了对即将到来的音调的预期。结果表明，声调和反应之间的相容映射比不相容映射的反应时间短。尽管这些SRC和REC效应在大小上没有可靠的差异，但它们在参与者之间不相关。因此，尽管外源性和内源性反应启动在群体层面上可能在功能上是等同的，但在个体层面上是否如此尚不清楚。
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.
