Successful learning hinges on the evaluation of positive and negative feedback. We assessed differential learning from reward and punishment in a monetary reinforcement learning paradigm, together with cardiac concomitants of positive and negative feedback processing. On the behavioral level, learning from reward resulted in more advantageous behavior than learning from punishment, suggesting a differential impact of reward and punishment on successful feedback-based learning. On the autonomic level, learning and feedback processing were closely mirrored by phasic cardiac responses on a trial-by-trial basis: (1) Negative feedback was accompanied by faster and prolonged heart rate deceleration compared to positive feedback. (2) Cardiac responses shifted from feedback presentation at the beginning of learning to stimulus presentation later on. (3) Most importantly, the strength of phasic cardiac responses to the presentation of feedback correlated with the strength of prediction error signals that alert the learner to the necessity for behavioral adaptation. Considering participants' weight status and gender revealed obesity-related deficits in learning to avoid negative consequences and less consistent behavioral adaptation in women compared to men. In sum, our results provide strong new evidence for the notion that during learning phasic cardiac responses reflect an internal value and feedback monitoring system that is sensitive to the violation of performance-based expectations. Moreover, inter-individual differences in weight status and gender may affect both behavioral and autonomic responses in reinforcement-based learning.

This article examines the role of non-financial interest groups in EU financial regulatory decision-making. While regulatory capture theories clearly helped identify the causes for the incrementality in spite of the major shock the 2008 crisis had caused, this article will consider a range of regulatory policy initiatives that do not neatly conform with this theory. I examine the extent to which non-financial groups are able to have their preferences met in the making of three different consumer policies: the Mortgage Credit Directive (MCD), stricter regulations of retail investment products (PRIPs/KID) and the reform of EU level supervisory structures. By employing a process-tracing approach based on qualitative interviews to analyze political responses to the 2008 financial crisis, the article demonstrates that newly mobilized groups could translate key advocacy goals into policy by deploying counter-expertise and co-operating with policy-makers in some cases but not in others.
