One hundred twenty-eight preschool boys were subjects in a 4x2x2 factorial design to investigate the change in reinforcer efficacy as a function of prior stimulus exposure. The factors were: (1) amount of repetition, 5, 25, 45, or 65; (2) reinforcer, good or bell; and (3) satiator, good or bell. Two additional groups were run as control groups to…

A compilation of 165 references dealing with short term memory, this bibliography supplements "Short-Term Memory: An Annotated Bibliography" (August 1968). The time period covered is predominantly June 1968 to June 1969. Such aspects and topics as psychometrics, motivation, human engineering, vision, auditory perception, verbal and nonverbal…

Brain research indicates that sensory-motor experiences during childrens' preschool and early school years may be the foundation for later language development. (MLF)

Proposes that offering students activities that exercise right-brain functions (nonverbal, nonrational, spatial, and intuitive) helps students become more fully developed human beings and better writers. (RL)

The relative ease of learning with Bliss symbols or words was investigated using four moderately retarded and four severely retarded children (ages 6 to 9 and 14 to 17, respectively) as Ss. It was found that Bliss symbols were the more easily learned and this was most evident among the severely retarded Ss. (Author/PHR)

Summarizes experiments indicating that a basic key to learning is the development of concepts of pattern recognition and the appropriateness of using a particular theorem. (Author/SK)

The Baudhuin Preschool of Nova Southeastern University (Florida) provides a four-tiered program for children with autism and related disorders. Each tier represents a continuum of services, strategies, and environments from most restrictive to inclusion. Each child's program combines systematic instructional techniques based on principles of…

The performance of 20 children with educable mental retardation (ages 8 to 12) and 20 verbal mental age-matched nonretarded controls was compared on identifying emotional facial expressions and producing the equivalent word adjectives. There were no significant differences between the two groups in general, despite the fact that children with…

Two experiments examined the effects of reductions in cortical cholinergic function on performance of a novel task that allowed for the simultaneous assessment of attention to a visual stimulus and memory for that stimulus over a variable delay within the same test session. In the first experiment, infusions of the muscarinic receptor antagonist…

Recent advances in neuroimaging and genetics technologies have enhanced our understanding of neurodevelopmental disorders in adults. The authors in this volume not only discuss such advances as they apply to adults with learning disorders, but also address their translation into clinical practice. One cluster of chapters addresses developmental…

This study was designed to investigate the functional similarity of the mental processes children use to learn verbal tasks and pictorial tasks. Children in grades 3 and 6 (n=144) and in grade 9 (n=112) were given four short paired-associate tasks entitled Pictures, Concrete Words, Abstract Words, and Japanese Characters. The tasks consisted of…

The study examined whether the development of receptive language lags behind nonverbal cognitive development in school age persons with mental retardation. Results indicated that the relationship between receptive language and mental age varied across mental age levels, linguistic forms, and individuals at the same mental age for listeners with…

Adolescents with nonverbal learning disabilities are characterized by poor fine graphomotor skills, poor organization, and inaccurate perceptions of social situations. Effective remedial interventions include training students in study skills, writing skills, organizational skills, and social skills, and in ways to plan, risk, and act on their own…
