A quasi-experimental study was conducted on temporal effects of intergroup contact on nondisabled (ND) children's attitudes toward disability. Children from a mainstream primary school were involved in an integration program with children from a school for children with severe learning disabilities (SLD)(3). Measures were administered 3 times over a period of 3 months to 26 integrating (experimental) and 24 nonintegrating (control) children. Social orientations in the experimental group became significantly more positive over time, while the control group showed little change. The experimental and control children initially categorized on the basis of gender and disability; subsequently the strategies of the experimental children were more idiosyncratic while the control children still used the same two dimensions.
