  • Title: Brain activity during emotion perception: the role of attachment representation.
    Author: Fraedrich EM, Lakatos K, Spangler G.
    Journal: Attach Hum Dev; 2010 May; 12(3):231-48. PubMed ID: 20473795.
    Abstract:
    To examine emotional face processing in mothers of different attachment representations, event-related potentials were recorded from 16 mothers during presentation of infant emotion faces with positive, negative or neutral emotional expressions within a three-stimulus oddball paradigm, and frontal asymmetries were assessed. Insecure mothers, as compared to secure ones, showed a more pronounced negativity in the face-sensitive N170 component and a smaller N200 amplitude. Regarding the P300 component, secure mothers showed a stronger response to face stimuli than insecure mothers. No differences were found for frontal asymmetry scores. The results indicate that attachment differences may be related to neuropsychological functioning.
