During the very first (subject) top, half a dozen feel brands were outlined. These consisted of confident cued trials, negative cued examples, basic non-accessory cued examples, self-confident uncued samples, bad uncued samples, and you may natural non-attachment uncued products. The beginning go out try picked if the target images had been presented. At second (group) peak, T-tests were chosen for comparison. The brand new contrast photos (basic cued trials-feelings cued trials for attentional wedding, feeling uncued examples-natural uncued examples getting attentional disengagement) away from several groups was basically the fresh input data. To determine whether or not there clearly was high activation corresponding to per contrast, a reversed p = 0.05 and you can the total amount endurance of team dimensions = 20 voxels into height (intensity) were utilized just like the threshold.

Behavioural investigation

In repeated measures ANOVA of 2 (group) ? 2 (cue validity) ? 3 (emotion valence), a significant main effect of cue validity was observed (F1,29 = ; p < 0.001); a significant main effect of emotion valence was observed (F2,62 = ; P < 0.01); the interaction of cue validity and attachment style reached significance (Fdos,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 (Fdos,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 1,29 = 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 (F2,62 = 4.23; p < 0.05); the main effect of theme also reached significance (Fdos,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).

Because the found from inside the Desk 3 lower than, significant correlations of these two attentional section in different thinking resided in both new safer and you can avoidant organizations.

Classification studies

Whenever we compared the team consequences, this new examine away from avoidant class so you’re able to secure class revealed significant activation about entire-head analysis. Avoidant people presented stronger activation in the right advanced temporary gyrus, center occipital gyrus, plus the left medial front gyrus, center occipital gyrus, second engine area, and you may cingulate gyrus than just safer some body (FWE = 0.05, class proportions = 20) (Fig. step 3 and Table 4).

Whenever considering the new attentional wedding of secure somebody, significant activation from the proper fusiform gyrus (x = 45–66, y = ?54–66, z = 3–15) therefore the center occipital gyrus in order to bad feelings (level voxel enhance, x = 48–54, y = ?75, z https://datingranking.net/trueview-review/ = ?3–0,) was discovered, not to confident feeling (FWE = 0.05, people dimensions = 20). Their activation from disengagement was nearby the effect from wedding in order to bad feeling (Fig. 4).
