Because disabled learners may profit from procedures using gradual stimulus change, this study utilized a microcomputer to investigate the effectiveness of stimulus equalization, an error reduction procedure involving an abrupt but temporary reduction of dimensional complexity. The procedure was found to be generally effective and implications for…

A correction procedure, including interruption, physical guidance, verbal instruction, and repetition, was used to train five students with severe/profound mental retardation to reject unmatching referents to their gesture mands. Trainers are urged to assess student response when items not matching the referent of a prior request are offered.…

Two experiments with a total of 17 adolescents or adults with severe mental retardation evaluated the potential of exclusion procedures (selection of an undefined object in comparison with a defined object) as a means of training basic naming skills. Reliable exclusion and naming performance were demonstrated in nearly all subjects. (DB)

Two students with moderate to severe mental retardation learned delayed matching to sample in which some of the trials involved complex sample stimuli, each consisting of a picture and a printed word. Matching to either the preceding picture or printed word sample was reinforced. Evidence for the formation of equivalence classes was observed.…

This study examined the matching and sequencing of quantities, numerals, and arbitrary forms by two individuals with mental retardation. Results showed that sequence training did not readily lead to new matching performances, unlike prior research with college students. Instead, training in matching to sample yielded emergent sequence production…
