Proactive response preparation contributes to contingency learning: novel evidence from force-sensitive keyboards.
Contingency learning can involve learning that the identity of one stimulus in a sequence predicts the identity of the next stimulus. It remains unclear, however, whether such learning speeds responses to the next stimulus only by reducing the threshold for triggering the expected response after stimulus onset or also by preparing the expected response before stimulus onset. To distinguish between these competing accounts, we manipulated the probabilities with which each of two prime arrows (Left and Right) were followed by each of two probe arrows (Up and Down) in a prime-probe task while using force-sensitive keyboards to monitor sub-threshold finger force. Consistent with the response preparation account, two experiments revealed greater force just before probe onset on the response key corresponding to the direction in which the probe was more (versus less) likely to point (e.g., Up vs. Down). Furthermore, mirroring sequential contingency effects in behavior, this pre-probe force effect vanished after a single low-probability trial. These findings favor the response preparation account over the threshold only account. They also suggest the possibility that contingency learning in our tasks indexes trial-by-trial expectations regarding the utility of the prime for predicting the upcoming probe.
期刊介绍:
Psychological Research/Psychologische Forschung publishes articles that contribute to a basic understanding of human perception, attention, memory, and action. The Journal is devoted to the dissemination of knowledge based on firm experimental ground, but not to particular approaches or schools of thought. Theoretical and historical papers are welcome to the extent that they serve this general purpose; papers of an applied nature are acceptable if they contribute to basic understanding or serve to bridge the often felt gap between basic and applied research in the field covered by the Journal.
