Setup for online ratings task and longevity of first impressions formed during the transcranial magnetic stimulation (TMS) session. Three days after the TMS session in the lab, subjects were asked to complete an online rating task (a) in which they evaluated the likeability of the 144 neutral faces (first encountered during the TMS session). These faces were intermixed with 36 foils. Subjects used a continuous scale unanchored by numbers and were given unlimited time to respond. The bar graph (b) shows the neutral-face likeability ratings outside of the lab, separately for faces that had been presented in the TMS session after continuous theta-burst stimulation (cTBS) to the lateral prefrontal cortex (lPFC) or to S1, following the presentation of positively or negatively valenced emotional expressions. The error bars represent ±1 SEM of the within-subjects difference between valence conditions. The asterisk indicates a significant difference (p < .05).
