One or two degrees of ANOVA methods were utilized to deal with fMRI investigation
During the earliest (subject) top, half dozen experiences brands have been defined. These contains self-confident cued samples, negative cued examples, neutral low-connection cued examples, self-confident uncued trials, bad uncued trials, and you will natural non-attachment uncued trials. The new beginning day try selected if the target images have been presented. From the next (group) level, T-tests were used in investigations. The latest evaluate images (simple cued products-feelings cued samples to have attentional engagement, feelings uncued samples-simple uncued examples to have attentional disengagement) from a few teams was the fresh new input data. To decide whether there was significant activation comparable to per examine, a reversed p = 0.05 and you will the amount endurance from team proportions = 20 voxels for the top (intensity) were used while the 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 omegle (Fstep 1,29 = ; 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 (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 (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 one,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, 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).
Once the shown into the Desk 3 below, tall correlations of the two attentional portion in different thinking stayed in new secure and you will avoidant groups.
Category data
Whenever we opposed the team effects, this new examine out-of avoidant group to help you secure category shown high activation on the entire-notice research. Avoidant people exhibited stronger activation on proper premium temporal gyrus, middle occipital gyrus, and leftover medial frontal gyrus, middle occipital gyrus, secondary system city, and you may cingulate gyrus than just safe anyone (FWE = 0.05, class proportions = 20) (Fig. step 3 and you may Dining table cuatro).
When checking out brand new attentional wedding off safer anyone, high activation regarding best fusiform gyrus (x = 45–66, y = ?54–66, z = 3–15) additionally the center occipital gyrus to negative feelings (height voxel complement, x = 48–54, y = ?75, z = ?3–0,) were discover, yet not in order to confident feeling (FWE = 0.05, group proportions = 20). Its activation out of disengagement is actually around the response away from wedding so you can negative feeling (Fig. 4).
