Correlation plots. The picture shows four plots where correlations between valence and arousal are observable. Plots (A) and (C) show the results for the posture trials; (B) and (D) the ones for the IAPS trials. A positive correlation is appreciable for positive emotional pictures (happiness; plots C and D), meaning that higher valence corresponds to higher activation; the opposite is observable for negative pictures (fear; plots A and B), even though for IAPS, stimuli significance was not reached after Bonferroni correction. Both valence and arousal are reported as values on the 0–9 Likert scale. Legend: $ = p > 0.05.
