Several quantities of ANOVA strategies were used to cope with fMRI research
At the first (subject) peak, half a dozen feel models was in fact outlined. This type of contains confident cued trials, bad cued examples, simple low-attachment cued trials, positive uncued samples, negative uncued trials, and you may basic low-connection uncued products. The brand new onset date try selected in the event the address photo was basically showed. At next (group) top, T-testing were chosen for assessment. The evaluate photo (natural cued trials-emotion cued samples to own attentional involvement, feelings uncued examples-natural uncued samples to possess attentional disengagement) out-of two teams was this new input studies. To choose if or not discover tall activation comparable to for every compare, a stopped p = 0.05 and you can extent threshold out-of how does swapfinder work party proportions = 20 voxels for the level (intensity) were used once the threshold.
Behavioral study
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 (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 1,31 = 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, 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 found in Dining table step three less than, extreme correlations of the two attentional areas in different thinking existed in both the fresh new secure and you may avoidant teams.
Classification study
Whenever we opposed the group outcomes, the fresh examine away from avoidant group in order to safer category shown significant activation about whole-notice data. Avoidant some one presented healthier activation regarding the correct advanced temporal gyrus, middle occipital gyrus, while the leftover medial frontal gyrus, middle occipital gyrus, second engine town, and you can cingulate gyrus than safer some body (FWE = 0.05, class size = 20) (Fig. step 3 and you can Table 4).
When checking out new attentional wedding away from secure individuals, extreme activation regarding best fusiform gyrus (x = 45–66, y = ?54–66, z = 3–15) in addition to middle occipital gyrus so you can bad feelings (top voxel coordinate, x = 48–54, y = ?75, z = ?3–0,) was in fact receive, not to help you self-confident feelings (FWE = 0.05, people proportions = 20). Their activation away from disengagement try nearby the impulse off wedding to help you negative emotion (Fig. 4).
