The capacity to attend to task demands while viewing nontask-related emotional stimuli undergoes profound development during adolescence. However, researchers are only beginning to explore neurobiological correlates of this cognitive process. In the present investigation, 17 adolescents (9-17 years of age) and 17 adults (25-36 years of age) were scanned using event-related fMRI at 3T. Subjects viewed neutral and emotional faces (angry, fearful and happy) passively and also while attending to emotional and physical features. In the initial analysis, three main results emerged. (1) Adolescents showed greater amygdala and prefrontal cortex activation than adults during passive viewing of angry vs. neutral faces. (2) Both adults and adolescents engaged ventral lateral and dorsal prefrontal regions while attending to internal fear state during angry vs neutral face viewing. (3) Greater discriminant activation emerged in adults vs. adolescents within the contrast of internal fear rating to angry faces vs. physical feature rating to the same angry faces. These results document developmental differences in the effects of emotional stimuli on attention-related brain engagement.
