Behavioral variability as a function of noncontingent adult attention, peer availability, and situational demands in three hyperactive boys.

Recommendations about placements for children in need of special education are routinely made and carried out without empirical validation for the efficacy of particular approaches nor the appropriateness of an approach for a particular child. A study was designed to examine a methodological model which focuses on empirically deriving recommendations for the most appropriate teaching situation for any given child requiring special education. Prosocial, problem, and task-related behaviors in three hyperactive boys were assessed in eight prearranged situations: (1) group play with one adult supervising; (2) group play with three adults; (3) group teaching with one adult; (4) group teaching with three adults; (5) individual play with low density noncontingent adult attention; (6) individual play with high density noncontingent adult attention; (7) individual teaching with low density noncontingent adult attention; and (8) individual teaching with high density noncontingent adult attention. Behaviors assessed included adult, peer, and target child attention given and received; compliance; aggression; disruption; task involvement; and percent tasks correctly completed of tasks attempted. Data revealed that the most disruptions and least efficient task performance occurred in the group teaching situation with one adult. The most efficient task performance and fewest disruptions in a teaching situation occurred in the individual teaching setting with high density noncontingent adult attention. In addition, overall mean rates of disruptive behavior were higher in group situations than in individual situations. The data strongly validate the need for carefully selecting educational environments for problem children, and that the behavior of such children is, at least, partially influenced by environmental factors.

Developmental and degenerative patterns associated with cognitive, behavioural and motor difficulties in the Sanfilippo syndrome: an epidemiological study.

The results of a survey given to parents with Sanfilippo syndrome (MPS III) children (n = 30) are described with an emphasis in several areas. Developmental and degenerative patterns are outlined in detail and contrasted with developmental milestones of normal children. An essentially uniform pattern of behaviour problems was discovered and is discussed along with the efficacy of pharmacological and non-pharmacological approach to remediation. Finally, practical suggestions are offered for physicians and parents which are encountered by the daily management problems of children with this disorder.

Nonretarded and mentally retarded children's performance on a manual-control task with and without visual feedback.

Performance differences between 10 nonretarded and 10 retarded persons on a manual-control task were examined. More specifically, the focus was on possible relationships between the subjects' abilities to control their response forces and the focus of their attention. The subjects, who were closely matched for MA, were required to exert force on a transducer within a selected force bandwidth for 3 seconds to obtain a reinforcer. Results suggested that the ability to discriminate internal cues is related to IQ differences.
