However, much is still unknown about learning to expect social feedback. 68 female participants engaged in the Social Evaluative Learning through Feedback Profile task, based on which we mapped out cardiac and expectation markers of social anxiety. In this task, four peers differed in their probability of giving rejecting feedback (i.e., 85, 70, 30, and 15 %) on statements about the participant, and participants predict whether the peer will accept or reject them. To estimate learning, participants’ predictions are grouped based on the peer’s dominant response. Heart rate (HR) slowing is measured for each stimulus using interbeat intervals. We calculated high-frequency resting heart rate variability (HRV), and the Liebowitz social anxiety scale was used as a screener. Multilevel models predicted HR slowing, and learning to predict peer feedback. Our analysis shows that HR slowing after unexpected rejection decreases over the course of the experiment. For the most accepting peer, higher social anxiety is associated with more HR slowing for unexpected rejection, and less HR slowing for expected rejection. For the most rejecting peer, there seems to be an opposite effect. Classification of all peers became more accurate over time. We found a weak negative correlation between resting HRV and social anxiety. We conclude that there are slight differences in HR slowing associated with higher social anxiety. The current findings help practitioners understand cardiac and emotional responses to social learning based on feedback and can aid researchers’ understanding of social anxiety.Show less
