The results of three experiments involving 6 young children suggest that the generalized imitation effect may not be entirely due to the child's inability to discriminate reinforced fron nonreinforced occasions. Instructional and social variables may strongly influence the generalized imitation effect. (WY)

Studied developmental changes in optional shift discriminations using kindergartners, second graders, sixth graders, and college students. (DR)

The effects of varying training settings and objects on the development of skill generalization were studied with 60 retarded students (5-16 years old). Research procedures were identical for all groups except for the manipulation of settings and objects. A factorial analysis of covariance supported the prediction that the visual discrimination…

Procedures were used to assess capacity to sustain adaptive responding and discrimination learning ability in 18 psychotic nonverbal children. It was concluded that the measures had good face validity with respect to assessment of discrimination, learning ability, and tolerance for intermittent reinforcement. (SB)

Following pretraining on three figures, 44 nonhandicapped preschoolers were assigned to experimental groups to investigate methods of integrating a new, similar symbol into a set of familiar symbols to approximate the difficult disciminations encountered by young children in school. (Author)
