Emotional processing in institutionalized adolescents using an affective attachment-related database: an fMRI study
| Resumo: | Institutionalization is a worldwide option for at-risk children and adolescents, despite depriving them of the expected experiences to typical development, such as creating a selective relationship with a caregiver. Having an attachment relationship is a milestone in children, and a factor to have into consideration when studying adolescent behaviour. Relative to the impact of institutionalization in the emotional processing and brain correlates some studies indicate alterations associated with reward system areas. This study aimed to understand the brain processing of positive stimulus, more specifically, attachment-related ones in a population of institutionalized adolescents. For this purpose, a group of adolescents currently living In institutional settings, and a group of adolescents in family care were recruited. The experimental task presented to the participants was a passive visualization task, using the Besançon Affective Picture Set-Adolescents (the BAPS-Ado) database. For this study, only the category of joy-complicity images was analysed, positive images showing complicity between friends or parents. The attachment-related self-report questionnaires did not reveal differences between the groups. Although, differences between groups emerged in the brain activity, with the institutional reared group having a higher activation in left cerebellum, an area recently associated with emotional processing and social stimuli. |
