abstract = {The human brain contains social areas that become active when interacting with another human. These
are located in the ventral prefrontal and mediodorsal cortices, adjacent to areas involved in reward processing
and cognitive control. Human behaviour is strongly influenced by the social context. This is particularly evident
when observing greater risk propensity in the presence of a peer, particularly during adolescence and emerging
adulthood. We explored the widely held view that enhanced risk propensity is the consequence of weak cognitive
control. We used brain activity, estimated from EEG recordings in a sample of 114 emerging adult dyads whilst
performing a risk perception task, to predict risk behaviour in a subsequent driving simulation task. Being with
a peer reduced the ability to discriminate riskiness in images of traffic scenes, biased responses towards the perception
of no-risk, and increased the rate of accidents in the driving simulation. Risk perception involved three
sets of clusters showing activity only when being with a peer, only when being alone, and in both social contexts.
Functional connectivity between the clusters accounted for the later driving simulation performance depending
on the peer’s presence. In the light of our findings, greater risk-taking, when a peer is present, seems to be triggered
by the activation of a different, less efficient brain network for risk-processing.},
