Drug treatment did not influence the participants RTs to geometric figures. Yet, the type of target (F2,110 = 39.485; p < 0.001; np2 = 0.418) and the interaction between target and distractor (F2,110 = 25.871; p < 0.001; np2 = 0.32) influenced the participants’ RTs in the control task (see also Table S2). These results are consistent with the assumption that simple geometric forms could have emotional meanings and may even trigger an attentional bias27.
