A review of research since Ayers' (1972) report on sensory integration (SI) concludes that SI is not supported as an effective treatment for academic problems of children with learning disabilities. It is not clear whether SI is more effective than perceptual-motor approaches or maturation alone. (SK)

Previous research has demonstrated that compensatory movements for changes in visuomotor coupling often are not consciously detected. But what factors affect the conscious detection of such changes? This issue was addressed in 4 experiments. Participants carried out a drawing task in which the relative velocity between the actual movement and its…

Historically, sensory systems have been largely ignored as potential loci of information storage in the neurobiology of learning and memory. They continued to be relegated to the role of "sensory analyzers" despite consistent findings of associatively induced enhancement of responses in primary sensory cortices to behaviorally important signal…

The experiments examined qualitative and quantitative changes in the dynamics of learning a novel motor skill (roller ball task) as a function of the manipulation of a control parameter (initial ball speed). The focus was on the relation between the rates of change in performance over practice time and the changing time scales of the evolving…

Olfactory discrimination (OD) learning consists of two phases: an initial N-methyl-d-aspartate (NMDA) receptor--sensitive rule-learning phase, followed by an NMDA receptor (NMDAR)--insensitive pair-learning phase. The rule-learning phase is accompanied by changes in the composition and function of NMDARs at synapses in the piriform cortex,…

Autonomously developing organisms face several challenges when learning reaching movements. First, motor control is learned unsupervised or self-supervised. Second, knowledge of sensorimotor contingencies is acquired in contexts in which action consequences unfold in time. Third, motor redundancies must be resolved. To solve all 3 of these…

This study investigated the static balance performance of 20 nonhandicapped and 20 learning disabled male children in Texas by comparing mean distances of center of pressure displacement as measured by a forceplate. Specifically, mean displacements in the medial-lateral plane during five static balance tests were measured from a neutral starting…

Conservation of weight is known to be achieved at a conceptual level at about 9 years of age. Infant behavior seems to indicate that between 6 and 18 months of age they develop a sensorimotor form of conservation. (Author/RC)

This study was designed to discover whether a student learns to imitate the skills demonstrated in a motion picture more accurately when the supportive descriptive terminology is presented in an auditory (spoken) form or in a visual (captions) form. A six-minute color 16mm film was produced--"Determining the Test Weight per Bushel of Yellow Corn".…

An experiment apparatus tested two hypotheses: a) supplementary feedback aids learning when it provides information by which to distinguish long target contacts from short ones; b) supplementary feedback, especially if immediate, facilitates performance by providing secondary reinforcement. Five groups, of 20 subjects each, were given 60 trials,…

The article presents techniques for teaching gifted children with the clumsy child syndrome. (Author/SBH)

Examined eight-month-olds' ability to remember the location of a hidden object, using a nonsearch task. Results suggested that the infants remembered the object's location, and were surprised when it had been moved. (SKC)
