Objective: The aim of this study was to compare the effect of different emotional stimuli, neutral, positive and negative, on time perception in children with attention-deficit/hyperactivity disorder (ADHD) and normal children in dual-task form. Method: Five hundred and ninety-nine students from primary schools were randomly selected. The Conner's Teacher Rating Scale (CTRS) questionnaire was completed by teachers. 100 individuals with a screening above the cut-off points in CTRS were further assessed by the Children Symptom Inventory (CSI-4). 34 children with ADHD and 31 controls were administrated a time discrimination task in two blocks of 1000 ms and 2000 ms duration. Children were asked to compare three image groups; neutral with neutral, neutral with positive, and neutral with negative images. Results: Children with ADHD had significantly better performance in the time discrimination task across all conditions when compared with controls: on average, time intervals were approximately 35 ms shorter for the children with ADHD. Conclusions: These finding suggests that children with ADHD overlook the details regarding complex stimuli (i.e. emotional stimuli) resulting in higher time discrimination sensitivity. The result is interpreted in the framework of the attentional gate model. Keywords ADHD, time perception, time discrimination, dual-task
