Heightened neural sensitivity to social exclusion in boys with a history of low peer preference during primary school | Developmental and Cognitive Neuroscience | 2020“Prior work has shown that low peer preference during primary school is linked to the development of rejection sensitivity in late childhood and that during this period links between social preference and internalizing problems become more profound (Ladd, 2006; London et al., 2007; McLachlan et al., 2012). Our results suggest that prolonged experiences of low peer preference become embodied in children’s neurobiology during primary school. This embodiment of negative peer experiences may possibly explain their negative impact in development. Our findings emphasize that teachers, school psychologists and clinicians must be aware of the impact of low peer preference and exclusion on primary school children, and that schools should monitor and intervene in classroom peer rejection as early as possible”
