Results were obtained using a three-way mixed-design ANOVA with within-participant factors of “emotion” (positive, neutral, and negative) and “sociality” (social and non-social), as well as the between-participants factor of “group” (High-AQ and Low-AQ). Significant (p < 0.05) comparisons are indicated in boldface.
