Tening faces (vs shapes) following neutral or attachment priming, in participants
Tening faces (vs shapes) following neutral or attachment priming, in participants who’ve low or higher levels of state anxiousness ( s.d. below or above the mean). (B) Graph shows mean BOLD signal transform in the proper dorsal amygdala in response to threatening faces (vs shapes) following neutral or attachment priming (coded as a dummy variable), in participants that have low or high levels of state attachment security ( s.d. under or above the imply).We examined no matter if trait anxiousness and attachment dimensions moderated the association amongst priming effects and amygdala activation and located no considerable effects. Nonetheless, state anxiousness prior to the priming moderated the effect of priming on left dorsal amygdala activity (t .2, P 0.028; two 0.66). Higher initial levels of state anxiousness had been associated with larger effects of attachmentsecurity priming on reducing amygdala threat reactivity ( .427; P 0.00) than low levels of state anxiousness ( 0.020; P 0.840) (Figure 2A). In addition, state attachment safety at time one (prescanning) substantially moderated the influence of attachment priming on amygdala reactivity to faces (t .70, P 0.00; two 0.five), with low initial levels of state attachment security connected using a bigger effect of attachment priming on minimizing correct dorsal amygdala threat reactivity ( .326; P 0.008) relative to low levels of state attachment security ( 0.two; P 0.296) (Figure 2B). Dotprobe behavioural data As anticipated, participants showed an attentional bias towards threatening stimuli; i.e. there was a principal impact for trial type [F( 38) four.77,P 0.035, two 0.2] with participants responding substantially extra p immediately towards the threatcongruent trials (M 425.32 ms, s.d. 57.67) than for the incongruent trials (M 432.4 ms, s.d. 53.92). The group by trial type interaction failed to reach significance [F( 38) 3.58, P 0.066, two 0.086) but interestingly participants inside the p attachmentsecurity priming condition (M 3.29, s.d. 25.66) tended to show a larger attentional bias than handle participants (M .95, s.d. four.6). fMRI activation results: dot probe Group variations At the whole brain level, there had been no betweengroup differences in activation to any contrast. Inside our ROIs, an independent ttest revealed significant betweengroup differences (control attachment primed group) in left dorsal amygdala ROI reactivity to both threat [t(37) two.47, P 0.08, 95 CI (0.03, 0.33), d 0.799] and neutral [t(36) two.60, P 0.03, 95 CI (0.045, 0.362), d 0.873] trials (see Figure three). There had been no considerable variations located in the right dorsal amygdala for either the threat trials [t(37) .28, P 0.207,Attachmentsecurity priming get Eupatilin attenuates amygdala reactivitySCAN (205)Fig. three The attachment priming group show considerably significantly less left dorsal amygdala activation within the dotprobe task.

Correlations with scales and moderation analysis There had been no optimistic correlations between amygdala activity throughout the dotprobe activity and scores on any of the questionnaires (all P 0.), nor did we locate any moderation effects of trait anxiety, attachment dimensions and state anxiety. Our study extended preceding study by investigating irrespective of whether the provision of secureattachment reminders can reduce t.
