Differential effects for attachment-styles during social exclusion: An ERP study
Supervisor: Dr Linda Mayes
Course: MSc in Developmental Neuroscience and Psychopathology
In a three-year follow-up 23 adolescents (11-15 years; 15 male, 8 female) previously classified secure and insecure-dismissing were administered a virtual ball-tossing game. Playing with pre-programmed “peers” involving consecutive conditions of inclusion, exclusion and re-inclusion, event-related potentials were sampled in response to exclusion and receiving balls (Favors) during inclusion versus re-inclusion.
No differences between attachment-classifications emerged during exclusion, although average amplitudes of two late components were highly correlated with self-reported ostracism distress.
Favors yielded a significant group by condition interaction with secure children remaining relatively stable, but dismissing children evidencing an exaggerated N400-like potential pre- versus post-exclusion. Findings are consistent with protracted recovery times for dismissing versus insecure children, despite activation of similar magnitude concurrent to a social stressor.
