The present study explored typically developing children's understanding of, and attitudes towards, the inclusion of children with physical disabilities (PD) in mainstream settings. The 60 children who participated in the study attended sixth grade in two mainstream primary schools (30 in contact with a child with PD and 30 without such contact). They filled in a questionnaire to measure understanding of disabilities and one to explore attitudes towards inclusion. Analyses revealed that children in contact with a child with PD had a better understanding of the emotional and social problems associated with the presence of PD than the comparison group. Moreover, children in contact with a child with PD expressed more positive attitudes towards the inclusion of children with PD in relation to children without such contact. Results are discussed in terms of the importance of contact in the formation of more positive attitudes towards the inclusion of children with PD. (Contains 4 tables.)
