Children with Attention Deficit Hyperactivity Disorder (ADHD) face many academic and training problems and also impose some problems on their teachers and classmates. Motor learning can be categorized into two main types: implicit and explicit. The main goal of the present study was to investigate the possible differences between implicit and explicit motor sequence learning in children with ADHD and normal children by using serial reaction time task.

The sample consisted of 24 children with ADHD, who were equally assigned to explicit and implicit learning groups, and 24 normal children, also equally assigned to implicit and explicit learning groups. Each group, therefore, consisted of 12 participants. Repetitive Measure ANOVA was run to compare reaction time and error in different blocks, and squared t-test was used to compare regular and irregular blocks.

Comparison of implicit and explicit learning for accuracy (the number of reaction errors) and speed (response time) revealed the accuracy to be P=0.012 and speed P=0.012 in ADHD explicit group, and accuracy P=0.094 and speed P=0.954, in ADHD implicit group. Normal explicit group indicated accuracy of (P=0.008) and speed of (P=0.05) and normal implicit group indicated accuracy of (P=0.011) and speed of (P=0.442).

The results of the present study indicated that explanation and description of the task was more effective in motor sequence learning in ADHD children. It is, therefore, recommended that pre-exercise training be included in the programs provided to these children.

The aim of this study was to assess of both implicit and explicit motor sequence learning in children with attention deficit hyper activity disorder (ADHD) and typical peers, by serial reaction time task.

The sample size for each group was 12. The study sample was included 24 children with ADHD, in explicit learning group and implicit learning group. and 24 typical children was included in implicit learning group, and explicit learning group.ANOVA repetitive measured for comparing response time and errors in different blocks, and paired t-test was used for comparing regular and irregular blocks.

The comparision of implicit and explicit learning on, accuracy (error response) and speed (response time) in ADHD explicit group would indicate accuracy (P-value=0/012), speed (P-value=0/012) and in ADHD implicit groop would indicate accuracy (P-value=0/094), speed (P-value=0/954).so in typical explicit group would indicate accuracy (P-value=0/008), speed (P-value=0/05) and in typical implicit group showed that accuracy (P-value=0/011), response times (P-value=0/442).

This study showed that explain the task in motor sequence learning is more better in ADHD children. so before performing a task should be considered.
