Recent genetic studies indicate an association between Attention Deficit Hyperactivity Disorder (ADHD) and the dopamine transporter gene (DAT1) with possible preferential relation to hyperactivity and impulsivity behaviours. The present study investigated attention-related behaviours in a non-clinical sample to determine whether the modulation of these behaviours is associated with genetic variability of the DAT1 within the normal population. A secondary question explored whether gender was associated with the measured attention-related behaviours. Twenty-six children were observed in the classroom during performance of independent academic work. Motor behaviours during task performance were scored using the Restricted Academic Situation Scale. Major behavioural problems were scored using the Conners' Teacher Rating Scale-Revised: Short Form (CTRS-R:S). All participants were genotyped for the DAT1. The results yielded no significant genotype group differences, although an association was found between oppositional behaviour (CTRS-R:S) and gender. These preliminary results are discussed within the current context of genetics research in ADHD.
