The Minnesota Percepto-Diagnostic Test (MPDT) classifies remedial readers into three groups: primary, secondary, organic. This study of subjects aged 7-22 sought to determine if a significant negative relationship existed between (MPDT) scores and reading achievement and if error patterns differ significantly within and between the…

One of the most important vehicles for learning during the preschool years is the experience of physical activity. Carefully planned situations in which children experiment with the processes of moving furnish them with experiences in learning to control objects and their bodies. (JN)

Notes that copying is a common technique for training perceptual motor skills such as handwriting; describes an experiment in which stimuli to be copied were presented dynamically or statically close to or distant from children seven and 10 years old and discusses the implications of the results for teaching handwriting.

A neuropsychological assessment stressing lateralized perceptual-motor and cogntive abilities was administered in two groups of hospitalized psychiatric patients (8 to 17 years old), 25 schizophrenics, and 25 nonpsychotics. The results supported the hypothesis that there may be left hemisphere dysfunction in schizophrenia; however, no single…

Thirty-two moderately and severely retarded adults were engaged in a vocational evaluation and training program to determine the predictive value of four manual dexterity tests (subtests of the Minnesota Rate of Manipulation, the Pennsylvania Bimanual Worksample, the Crawford Small Parts Dexterity Test, and the Purdue Pegboard Test) as they relate…

The performance of 76 students (ages 10 to 15) with learning disabilities on four tasks of arithmetic computation within each of the four basic operations was examined. Tasks varied in difficulty level and number of strokes needed to complete all items. Intercorrelations between task sets and operations were examined as was the use of…

Compared coupling characteristics of clapping simultaneous with walking or galloping, consistency across trials, and phasing variability among 4-, 6-, 8-, and 10-year-olds. Found that for walk/clap tasks, children adopted adult-like coupling patterns by age 8 and with the same consistency by age 10. Across age, children became less variable in…

Notes children with movement difficulties do not receive neat diagnostic classification, as they have normal intelligence and minimal neurological signs. Details a study based on interviews of 11 parents of children with movement difficulties that revealed that parent involvement and knowledge is critical to acquiring professional attention.…

In the present study, an attempt was made to examine the nature and persistence of bilateral transfer of a throwing skill for a large sample of male and female children. One hundred sixty children ages 6, 8, 10, and 12 years were randomly assigned to either an experimental or control group with an equal number of boys and girls in each group. The…

Many studies of the neural mechanisms of learning have focused on habituation, a simple form of learning in which a response decrements with repeated stimulation. In the siphon-elicited siphon withdrawal reflex (S-SWR) of the marine mollusk "Aplysia," the prevailing view is that homosynaptic depression of primary sensory afferents underlies…

Consolidation theory proposes that through the synthesis of new proteins recently acquired memories are strengthened over time into a stable long-term memory trace. However, evidence has accumulated suggesting that retrieved memory is susceptible to disruption, seeming to consolidate again (reconsolidate) to be retained in long-term storage. Here…

A qualitative longitudinal study, first of four parts, compared developmental movement levels and academic learning levels in young children. Subjects were 28 children of various ages who were not working up to grade level but who did not qualify for learning disability services. Parents completed a detailed demographic survey and a neurological…
