“…Although Ernst and collaborators did not originally consider dopamine as a player in the avoidance module, they do propose that this module responds differently to situations with and without the presence of rewards: during adolescence the avoidance system is supposed to be hyper-responsive to treats in negatively valenced contexts, but is hyporesponsive in positively valenced contexts, when (potential) rewards are present (Ernst et al, 2006;Ernst, 2014). For reasons unclear to us, this model has received much less attention in the literature compared with dual-systems models, even though it is more comprehensive, has recent functional imaging support (Xu et al, 2021) and, importantly, describes many different ways in which dopamine changes modulate various aspects of learning, as in the above-mentioned Spiral of Motivated Actions. Exploring this additional aversive-avoidance aspect of behavioral change in adolescence in light of updated theories of dopamine function may be an interesting direction for future research.…”

Adolescence is characterized by increased risk-taking, which is often ascribed to developmental changes in dopaminergic signaling. These behaviors are believed to result from dopamine-induced hypersensitivity to rewards which overrides cognitive self-control mechanisms that are still immature at this age. However, the link between dopaminergic changes and adolescent behavior is often based on oversimplified notions about the workings and functions of dopaminergic pathways. Here we discuss the relationship between changes in the dopaminergic system and adolescents’ impulsive and risky behaviors in light of current evidence and theories about the roles of dopamine in behavior. We show that dopamine is much more strongly linked to learning, adaptive decision-making under uncertainty and increased motivation to work for rewards than to recklessness, reward-pursuit and/or choice impulsivity. Importantly, changes in the dopaminergic system also contribute to the maturation of cognitive control abilities through a variety of mechanisms, contrary to the false dichotomy between reward processing and cognitive control. Finally, we note that the functions dopamine is implicated in also involve a number of other neuromodulator systems, which interact with dopamine and also change during adolescence. These other neuromodulator systems have largely been ignored in the field of adolescent development, but a full understanding of adolescent behavior requires these neurochemicals and their interactions with dopamine to be taken into account.

“…The triadic model proposed by Ernst, Pine, and Hardin [11] offers an integrated framework for understanding adolescent risk-taking by emphasizing the interaction among three key neural systems: the reward system, the harm avoidance system, and the supervisory system. This model indicates that risk-taking may result from an overactive reward system, an under-responsive harm avoidance system, and an inefficient supervisory system, leading to a predisposition towards risky behaviors due to the predominant allure of immediate gratification over the potentially negative consequences.…”
