Overview of effect sizes on all dimensions analyzed. Effect sizes (Cohen’s d with Hedge’s correction) symbolized by arrows are shown for bipolar valence and arousal (left, light blue), unipolar pleasantness and unpleasantness (right, dark blue) and aggregated unipolar ratings (middle, gray) separately. Arrows’ appearance illustrates magnitude of effect sizes with bold = large (d>.80); 0∘ vertical = medium (d>.50). Arrows are shown only for ds with CIs not overlapping 0. Note that differences were the same for bipolar valence/arousal and aggregated unipolar ratings with the exception of the gender main effect and the comparisons involving “social-passive” pictures.
