An important pedestrian skill that young people with intellectual disabilities (ID) (mental retardation) find difficult is the ability to find a safe place to cross the road. Safe pedestrian behaviour relies on cognitive skills, including the ability to focus attention on the traffic environment and ignore irrelevant stimuli. Individuals with ID consistently demonstrate selective attention deficiencies. Other factors such as individual differences in cognitive style might play a role in road safety. The aims of the present study were to test any possible significant relationship between attention, cognitive style and identification of safe and dangerous road-crossing sites in preadolescents with ID. Participants were 40 boys with mild ID. Attention and field dependence-independence were assessed using the visual attention subtest of the Developmental Neuropsychological Assessment and the Children's Embedded Figures Test (CEFT), respectively. The participants were subdivided into two groups, matched on IQ. The two groups differed significantly in mean score on the visual attention subtest and on the CEFT. Analysis of variance showed that preadolescents with higher scores on both tests performed better than those who were more filed dependent and less attentive. Attention and cognitive style should be considered in the planning of road safety training for individuals with ID. (Contains 4 tables.)
