Underlying Sources of Genuine Response-Response Contingency Learning
SymposiumTalk-02
Presented by: Anna Martini
Research on habit formation is focused on demonstrating that implicit learning of regularities contributes to automatized behavior. Contingency learning paradigms provide an ideal test-bed to investigate this hypothesis. Recent studies on stimulus-response contingency learning (SR-CL) have shown that a large part of the SR-CL effect is explained by retrieval of a single most recent episode and thus should not be considered learning proper. Furthermore, the small residual SR-CL effect can be explained entirely by contingency awareness, suggesting that SR-CL reflects the functioning of propositional knowledge rather than the formation of associations. In the present study, we investigated response-response contingency learning (RR-CL), which is a more promising candidate for capturing implicit learning of action sequences. In a pre-registered study (n = 40), we obtained robust RR-CL effects, even after controlling for episodic retrieval of the most recent RR sequence. This residual RR-CL effect partially depended on contingency awareness; however, a residual RR-CL effect was also obtained in the absence of contingency awareness. These results suggest that the principles underlying learning of action sequences differ from those that characterize the learning of SR contingencies. The findings suggest that a large part of response sequence learning occurs automatically and outside of awareness, possible reflecting the formation of RR associations.
