Do attitudes towards persons with handicaps really shift over time? Comparison between 1975 and 1988

A replication of a study by Spreen (1977) was conducted to assess whether a positive shift in attitudes towards persons with mental retardation has occurred. Undergraduate students (N = 191) were tested. Results compared to those of Spreen (1977) showed a positive shift over the 13-year period. We also tested the hypothesis that exposure to a course on developmental disabilities and contact with individuals with mental retardation would improve students' attitudes. Findings support this hypothesis, although results suggest the influence of a third variable, namely, public awareness.
