| Abstract/Results: | ABSTRACT:
Attachment relationships influence the representations of the self and the others. This is thought to guide beliefs and perceptions, namely of emotional significant information as facial expressions of emotion(FEE). The goal of this work was to
understand how attachment dimensions are associated with neural responses to FEE. Twenty-seven healthy adults saw anger and happiness FEE, matched for arousal, and filled the Adult Attachment Scale, that measures the subscales of Anxiety, Close(comfort with intimacy) and Depend(sense of availability of others to one’s needs). A significant interaction between emotion and attachment showed that the 3 subscales were associated with N170 amplitude to happy, but not angry faces. Specifically, Anxiety scores predicted a reduction in N170 amplitude while Close and Depend scores predicted increased amplitudes to happy faces. An association was also found between the subscales and the LPP amplitude to both anger and happy faces in Anxiety (increased LPP) and in Depend (reduced LPP). Close scores were only negatively correlated with LPP amplitude for happy FEE. In sum, Anxiety affects the initial processing of happiness and leads to a larger later response to both FEE, possibly due to a hypervigilance to the meaning of these expressions towards the self. Contrarily, both Comfort with intimacy and Sense of Dependence increase early reactivity to happiness with reduced later processing (Depend for both FEE), illustrative of a secure pattern of emotional processing.
