Learning on the basis of outcome feedback shows pronounced developmental changes, however, much is still unknown about its underlying processes. In the current study, we aimed at decomposing how value updating, feedback monitoring and executing behavioral control contribute to children's probabilistic feedback learning. Children (ages 8-9), young adolescents (ages 11-13) and young adults (ages 18-24), performed two probabilistic feedback tasks: one required building a value representation on the basis of feedback (noninformed task), while in the other value representations were explicitly presented (informed task). Heart-rate was recorded to augment performance measures of feedback processing. We observed substantial developmental differences in heart-rate responses toward feedback in the noninformed task. Adult's heart-rate slowed more to negative compared to positive feedback relative to the children and young adolescents. In contrast, in the informed task all age groups showed larger heart-rate slowing toward negative compared to positive feedback. These results indicate that children are not impaired in monitoring probabilistic feedback per se, but have a specific deficit in building a task-appropriate value representation on the basis of probabilistic feedback.
