title: Attachment style dimensions are associated with brain activity in response to gaze interaction.
abstract: Aim of the present study was to investigate the time course of brain processes involved in the visual perception of different gaze interactions in woman-child dyads and the association between attachment dimensions and brain activation during the presentation of gaze interactions. The hypothesis was that the woman avoidance will produce a greater activation of primary somatosensory and limbic areas. The attachment styles dimensions avoidant-related will be associated with fronto-limbic brain intensity during the convergence of gaze. Electroencephalogram (EEG) data were recorded using a 256-channel HydroCel Geodesic Sensor Net in 44 female subjects (age: 24 ± 2 years). Event-related potential (ERP) components and standardized low-resolution electromagnetic tomography (sLORETA) were analyzed. Participants were administered the attachment style questionnaire before EEG task. A lower P350 latency was found in the fronto-central montage in response to woman avoidance. sLORETA analysis showed a greater intensity of limbic and primary somatosensory areas in response to woman avoidance compared to the others gaze interactions. In response to convergence gaze, the confidence attachment dimension was negatively correlated with the intensities of the right temporal and limbic areas, and the relationships as secondary attachment dimension were positively correlated with the intensities of the bilateral frontal areas and of the left parietal area.
