The Cognitive Mechanisms That Drive Social Belief Updates During Adolescence

Abstract: Adolescence is a key life phase for developing well-adjusted social behaviour. Belief updates about the trustworthiness of peers are essential during adolescence as social reorientation emerges and peer relationships intensify. This study maps the age-related changes of those belief updates during adolescence (n = 157, 10-24 years). We used computational modelling and an information sampling paradigm to reveal that three cognitive mechanisms contribute to age-related changes in those belief updates: prior beli… Show more

“…Importantly, specific impairments in the ability to consider the mental state of others or to respond to social signals are central to a range of psychiatric disorders, including borderline personality disorder and autism spectrum disorder 33 - 36 . In a separate study, we used an abbreviated version of the current task and revealed developmental changes in belief updates during adolescence 37 . This can provide a particularly relevant benchmark as the onset of many psychiatric disorders takes place during adolescence 38 .…”

“…Second, prior expectations (i.e., descriptive norms, the perceptions of what most people do 27 29 ) inform decision making by generating predictions about the behaviour of others (e.g., I will cooperate if this person is likely to reciprocate). Individual differences in initial expectations about others may lead to individual differences in choices 30 , and it is conceivable that different age groups have varying prior expectations 31 . However, prior expectations have hardly been studied in developmental populations, despite being important determinants of cooperative behaviours.…”

“…Participants were primarily recruited through previous studies that targeted both clinical and typically developing samples (Dekkers et al, 2019;Ma et al, 2020) et al, 2000) conducted at their home. The DISC-IV was adjusted to reflect changes from DSM-IV to DSM-5 where necessary.…”
