as the amygdala and nucleus accumbens (Spear, 2009). Oxytocin neurotransmission has been implicated in a variety of social behaviors, including facilitation of social bonding and recognition and memory for positive social stimuli (Insel & Fernald, 2004). Whether oxytocin-related changes undergird some of the changes in social cognition described by Blakemore, or the impact of peers on reward seeking that my colleagues and I have been studying, is a question that warrants more attention.
