Fig. 3: Electrocardiography and subjective evaluation.
From: Social threat avoidance depends on action-outcome predictability
A Grand average iHR series (difference from baseline in BPM, Beats Per Minutes) by Condition (n = 55). Shaded areas: within subjects 95% confidence intervals. Black thick dotted line: significant cluster of Condition effect in the GLM. Gray: Unpredictable condition. Red: Predictable condition. B Histogram of differences between avoid and approach values in the same dyad of avatars, for each stimulus of the subjective evaluation task and each participant (n = 46). C Proportion of avoidance, P(Avoid Angry), responses by subjective value quantile (0.2, 0.4, 0.6, 0.8, 1), by maximum instantaneous heart rate change from baseline (median split; gray: lower change, turquoise: greater change) and Condition (n = 45). Note that this plot represents only trials with slower RTs (median split) as the interaction with RT in the regression model showed that this effect is not present with fast RTs. Also note that while we illustrated the effect using median split of iHR change and quantiles of subjective value, the effect in the regression model is on continuous values.
