Summary

ADHD is a common childhood disorder characterised by difficulties with attention and behaviour. Various cognitive characteristics are associated with ADHD, such as executive and motivational difficulties. Beyond these characteristics, our hypothesis is that children with ADHD may have specific strategies for allocating mental effort, influenced by motivational and metacognitive factors Our study assesses these dimensions using a behavioural task and a computational model in children with ADHD, both with and without treatment. It aims to identify individual cognitive profiles correlated with clinical characteristics. A better understanding of the cognitive mechanisms involved in ADHD would enable the development of personalised management of the disorder.
