Human Growth and Development / Unit 9 HGD 1248 short lesson, about 20 seconds
Reward Sensitivity
Captions available
The idea
Adolescents are more sensitive to reward cues than children or adults, as changes in the brain's dopamine system raise sensation seeking and reward motivation.
In practice
The nucleus accumbens, a reward centre linked to the hippocampus and amygdala, active when a teen anticipates a prize.
Where people slip
Dopamine is a neurotransmitter, not a hormone; accounts of its role in adolescence remain hypotheses.
