The report presents summaries of 11 studies performed on 25-45 autistic students in a residential center to investigate processes of discrimination and response acquisition using automated reinforcement technology and exact timing procedures. The computer operated display and recording system for language and discrimination training is described and diagramed. Eleven studies using the system are then presented, with information and analysis of the following topics: (1) consistency among commonly used procedures for assessment of abnormal children; (2) classification of abnormal children: discrimination learning ability; (3) sustained responding under intermittent reinforcement in psychotic children; (4) autoshaping of abnormal children; (5) relationships among two experimental and four psychometric assessments; (6) the relationship between rate of rhythmicity and stereotypic behaviors. (7) intrinsic and extrinsic reinforcement value and sign formations as factors in the the sign language training of autistic children; (8) preattention and attention in developmentally delayed children; (9) oddity performance and the perception of relational information; (10) the effect of contingent vs. non-contingent presentation of rhythmic asynchronous stimulation on the stereotyped behavior of children with autism; (11) an automated research and training system for child-clinical populations.
