Subclaims¶

q2 i? During early and mid-adolescence (11-15 years), brain systems that seek rewards and process emotions are more developed than cognitive control systems responsible for good decision-making and future planning, meaning self-regulation is developmentally out of balance at this age. → Murray 2017

q2 · i? · review · r2

The brief reports this developmental neuroscience finding as background from research, citing it to argue that interventions during adolescence are important and timely. It is reported as a research finding rather than a new analysis in this brief.

"during early and mid- adolescence (i.e., 11-15 years), brain systems that seek rewards and process emotions are more developed than cognitive control systems responsible for good decision-making and future planning"
