The most commonly used model of nonverbal learning disabilities (NVLD) is the Rourke model. This model includes bilateral deficits in psychomotor skills as a primary neuropsychological deficit. Extant studies have identified attentional issues as one of the components seen in many children with NVLD. Forty-five children divided into three groups completed a battery of tests including psychomotor skills. Groups were defined as children with NVLD, children with attention-deficit hyperactivity disorder-Predominantly Inattentive type, and typically developing children. No significant differences were found among the groups on measures of motor speed. Furthermore, the means were not in the expected direction, as children with NVLD actually performed faster than typically developing children. This finding suggests that measures of motor speed should not be solely used to identify children with NVLD and that more research is needed to clearly identify appropriate diagnostic criteria.
