A few quantities of ANOVA procedures were utilized to cope with fMRI study

On basic (subject) level, six feel versions have been laid out. This type of contains positive cued trials, negative cued samples, natural low-accessory cued samples, confident uncued products, negative uncued samples, and you may basic low-accessory uncued samples. The fresh new onset time is actually chosen when the target photographs were exhibited. On 2nd (group) top, T-tests were used in review. The fresh new contrast photo (neutral cued trials-feeling cued products to have attentional engagement, feelings uncued trials-basic uncued trials for attentional disengagement) away from a couple groups were brand new input study. To decide if there is certainly extreme activation comparable to for every compare, a stopped p = 0.05 and you may the total amount tolerance of group size = 20 voxels to the top (intensity) were utilized because threshold.

Behavioral analysis

In repeated measures ANOVA of 2 (group) ? 2 (cue validity) ? 3 (emotion valence), a significant main effect of cue validity was observed (Fstep 1,30 = ; 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 (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 (F1,30 = 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) ? qeep support 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, Fdos,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 revealed in Table 3 less than, significant correlations of the two attentional section in various feelings existed in both this new safe and you may avoidant groups.

Class investigation

Whenever we compared the team effects, new compare regarding avoidant classification to help you safe class shown extreme activation regarding the whole-brain data. Avoidant anybody showed stronger activation in the proper premium temporal gyrus, center occipital gyrus, and remaining medial front gyrus, center occipital gyrus, secondary system urban area, and cingulate gyrus than safer anybody (FWE = 0.05, party size = 20) (Fig. 3 and you can Table 4).

Whenever looking at the brand new attentional involvement out of safe some one, extreme activation on the right fusiform gyrus (x = 45–66, y = ?54–66, z = 3–15) as well as the center occipital gyrus so you can negative feeling (top voxel enhance, x = 48–54, y = ?75, z = ?3–0,) was receive, however in order to positive emotion (FWE = 0.05, party size = 20). Its activation of disengagement are close to the impulse off wedding to bad feelings (Fig. 4).
