Low achieving regular class and educable mentally retarded (EMR) special class adolescents from a white, low-income, urban district were administered the learning potential procedure and were interviewed to determine differences in their after-school, non-academic activities. Few differences were reported in the social interests and activities of these two samples. The more able special class students reported themselves to be more isolated socially, engaged in more passive activities, or in athletics, did not belong to peer groups, disliked group activities, and said they did not desire to change their situation. The less able (nongainer) students reported more active social involvements with their peers. Data indicated that nongainers give socially desirable responses which do not reflect their actual behaviors. (For related studies, see also EC 042 064 and o42 065.) (Author/CB)
