From the first (subject) peak, six experience brands was basically outlined. These types of contains confident cued products, bad cued examples, simple low-attachment cued examples, self-confident uncued products, negative uncued examples, and you can natural low-attachment uncued examples. The fresh beginning day is chose when the address photo was basically showed. Within 2nd (group) peak, T-evaluating were chosen for testing. The contrast photo (neutral cued trials-emotion cued samples getting attentional engagement, feelings uncued samples-neutral uncued trials getting attentional disengagement) out of a few communities was in fact the fresh input study. To determine whether or not there is extreme activation add up to for every examine, a reversed p = 0.05 and you can the quantity threshold out of cluster size = 20 voxels into level (intensity) were used since tolerance.
Behavioral investigation
In repeated measures ANOVA of 2 (group) ? 2 (cue validity) ? 3 (emotion valence), a significant main effect of cue validity was observed (F1,30 = ; 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 (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 (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 (F1,31 = 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 (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).
Since found within the Table step three below, significant correlations of the two attentional areas in different attitude lived both in the brand new safer and you can avoidant teams.
Class study
As soon as we opposed the team effects, the brand new contrast out-of avoidant classification to help you secure class shown extreme activation on entire-head investigation. Avoidant some one showed more powerful activation on the proper premium temporal gyrus, middle occipital gyrus, while the kept medial front gyrus, middle occipital swinglifestyle gyrus, supplementary system urban area, and you may cingulate gyrus than secure anyone (FWE = 0.05, party dimensions = 20) (Fig. step 3 and you may Desk cuatro).
Whenever viewing the fresh attentional engagement regarding secure individuals, extreme activation throughout the right fusiform gyrus (x = 45–66, y = ?54–66, z = 3–15) additionally the center occipital gyrus to bad emotion (top voxel enhance, x = 48–54, y = ?75, z = ?3–0,) have been located, but not to confident feeling (FWE = 0.05, party dimensions = 20). Its activation out of disengagement try around the impulse regarding engagement so you’re able to negative feelings (Fig. 4).
