On first (subject) height, half dozen knowledge models was basically outlined. This type of contained positive cued samples, negative cued products, natural low-accessory cued samples, confident uncued trials, bad uncued products, and natural non-accessory uncued examples. The fresh new beginning date are chose when the target images was indeed exhibited. On second (group) top, T-screening were used in assessment. New contrast photos (natural cued trials-feeling cued examples getting attentional engagement, emotion uncued examples-natural uncued samples to possess attentional disengagement) off several teams was in fact the brand new type in studies. To determine whether there can be tall activation corresponding to for each and every compare, a stopped p = 0.05 and you may the total amount endurance out of team proportions = 20 voxels into height (intensity) were used since the threshold.

Behavioral research

In repeated measures ANOVA of 2 (group) ? 2 (cue validity) ? 3 (emotion valence), a significant main effect of cue validity was observed (Fstep one,31 = ; p < 0.001); a significant main effect of emotion valence was observed (Fdos,62 = ; P < 0.01); the interaction of cue validity and attachment style reached significance (F2,62 = 4.25; p < 0.05) (Table 2 and Fig. 2).

Attentional engagement and disengagement were analyzed by repeated ANOVA of 2 (attachment style) ? 3 (valence). Testing attentional engagement in the cued situation, the main effect of valence reached significance (F2,62 = 8.20; p < 0.01), the attentional engagement effect of positive emotion was ms (p < 0.01) and the attentional engagement effect of negative emotion was ms (p < 0.01). The difference between the two groups did not reach significance. Testing attentional disengagement in the uncued situation, the main effect of valence reached significance (Fstep one,31 = 5.24, p < 0.05). Further data showed the RT of neutral ( ms) was slower than positive emotion ( ms) and negative emotion ( ms), which means they did not show attention disengagement to attachment emotion.

When considering different emotion themes of parent-child and romantic images in the cued situation, no attentional engagement effect was found. In the uncued situation, the repeated ANOVA of 2 (group) ? 3 (valence) ? 2 (attachment theme) showed that the main effect of valence reached significance (Fdos,62 = 4.23; p < 0.05); the main effect of theme also reached significance (F2,62 = 6 .85; p < 0.05); the interaction of attachment styles ? valence ? themes reached significance, F2,62 = 3.56, p < 0.05. Testing the simple effect of emotion valence, the attentional disengagement effect of avoidant individuals for negative parent-child images was 7.08 ms (p < 0.05) and the attentional disengagement effect of secure individuals for positive parent-child images was ms (p < 0.05). Testing the simple effect of attachment themes, attentional disengagement of secure individuals for positive parent-child images was ms (p < 0.05). Attentional disengagement of avoidant individuals for negative parent-child images was ms (p < 0.05).

While the revealed in Desk step 3 less than, extreme correlations of the two attentional portion in different thinking existed both in brand new safe and avoidant teams.

Group studies

Whenever we compared the team consequences, this new examine of avoidant class so you can safe group revealed extreme activation about entire-head analysis. Avoidant anybody demonstrated more powerful activation regarding correct premium temporary gyrus, middle occipital gyrus, and also the left medial front gyrus, middle occipital gyrus, supplementary motor urban area, and cingulate gyrus than just secure somebody (FWE = 0.05, cluster size = 20) (Fig. step 3 and you may Dining table 4).

Whenever evaluating the fresh attentional wedding out of safe people, tall activation on correct fusiform gyrus (x = 45–66, y = ?54–66, z = 3–15) together with middle occipital gyrus so you can negative feeling (top voxel complement, x = 48–54, y = ?75, z = ?3–0,) have been receive, not to self-confident feelings (FWE = 0.05, cluster proportions = 20). Their activation off disengagement are close to the response of wedding so you’re able to negative feelings (Fig. 4).
