Evoked potentials and performance of 19 learning disabled (LD) and 19 normally achieving children (8 to 15 years old) were studied in two versions of the Continuous Performance Test (CPT). Results suggest a deficit in behavioral and cortical indices of sustained attention among LD children. (Author)

The behavior of eight hyperactive children was compared to 16 controls (9-10 years old) in two different classroom settings: an informal setting which involved choice and variety of tasks; and a formal setting which involved teacher specification of a small number of tasks. (Author/CL)

Investigated with 18 hyperactive boys (5 to 12 years old) and 18 controls were the effects of methylphenidate on a number of objective measures of activity level and attention on three repeated occasions in four types of settings: free play, movie viewing, testing, and restricted play periods.

Following the dynamic approach, it was hypothesized that 28 enuretic children (7 to 9 years old) would differ from nonenuretics in having more difficulty in expressing overt aggression toward their mothers than toward a neutral figure. (Author/SBH)

Results suggested that LD children suffer from a verbal mediational deficiency consistent with J. Flavell's mediation deficiency hypothesis. (Author)

D. Campbell and D. Fiske's multitrait-multimethod matrix was applied to data from two independent social learning measures designed to evaluate procedures used to aid 47 aggressive children (5-15 years old). (Author/CL)

Described are three studies which examined the effect of filmed modeling on cooperative play in disadvantaged children. (Author/CL)

Twenty adolescent male offenders and 36 nonoffenders were compared on two tasks designed to assess reactions to the nonverbal emotion expressions of others. (Author)

In Experiment I, the effects of a verbal warning, such as is used in Overcorrection, delivered contingently on the stereotyped mouthing behavior of two 10-year-old autistic/retarded children were examined. (Author)

Analyses of psychological, rating scale observational, and interview data showed that hyperactive children became less symptomatic over time; that the data did not provide evidence indicating that any of the treatments studied was more effective than any other or than no treatment at all. (Author)

The results indicated that over the 10 homes there was a strong inverse correlation between mean self-reported delinquency and the average amount of time youths spent talking to and in proximity to their group home parents. (Author)

The results showed that the majority of the autistic and the youngest normal children acquired only some limited features of the observational situation and chronological age was related to the amount of learning through observation in the normal children but not in the autistics. (Author)
