Soviet investigation of the development of verbal inhibition of preseverative manual behavior are reviewed. Non-soviet investigations of verbal-manual interaction are considered in relation to the Soviet view of the development of voluntary behavior; and it is argued, on the basis of this evidence, that the Soviet position need not stand or fall…

The use of pom-pom balls made of yarn in a classroom physical education program is described. (DB)

R. Schmitd's schema theory that there are generalized motor programs for a given class of movements was examined with 24 10-year-old educable mentally retarded boys and two nonretarded groups of boys matched on either MA or CA. (Author/SW)

Four developmentally delayed babies were given semicircular canal stimulation in an effort to facilitate their motor and reflex development. All of the children showed motor and/or reflex changes that were attributable to the vestibular stimulation. In addition, some evidence was obtained linking changes in stereotypic responding to the vestibular…

Five outdoor games beneficial to the development of children's motor skills are described. (LH)

The development of the ability to extend the hand across the body midline to contact a visually presented object was examined in 48 normal, full-term, 9- to 20-week-old infants. One of the infant's arms was restrained while the behavior of the contralateral, unrestrained arm was observed. (JMB)

Studied motor competence in 4-year-old children in Norway and tested 91 children using the Movement ABC test. Most striking was that only 1 of the 91 would be classified as "clumsy" within the fifth percentile of U.S. norms, and 7 children were "borderline." Seven of these eight children were boys. (SLD)

This study examined the relationship of crossing the midline while reaching for objects to the development of bimanual reaching among infants ages 12, 18, and 26 weeks. Findings indicated that the frequency of two-hand grabbing and the number of midline reaches increased with age; most midline reaches were part of two-handed reaches and occurred…

This study of six infants (three with blindness, three sighted) identified an underlying sequence in the development of crawling, with the ability to reach for an object and to move to or from the sitting position being the two most critical precursors to the actual execution of crawling. Infants with blindness had a lower frequency of activity…

Investigates whole body stiffness as a function of developmental level in the hopping of seven children of four-eight years. Proposes that stiffness may be a key parameter that is controlled by the central nervous system when children hop. (RJC)

Studied effects of changing internal and external constraints on the development of jumping in children of three, five, seven, and nine years, and adults. Results revealed no differences in the pattern of coordination for jumping. Differences were found in the position and magnitude variables. (RJC)

Describes the perception-action approach and the dynamic systems approach to motor development. Discusses the importance of understanding the development of the brain and the importance of longitudinal studies of motor development. (RJC)

This preliminary investigation of stuttering development and maturation of speech motor processes recorded the electromyographic activity of the orofacial muscles of nine children who stuttered. Results suggest that the emergence of tremor-like instabilities in the speech motor processes of stuttering children may coincide with aspects of general…

Examined asymmetries in movement behaviors of 36 full-term, newborn infants. The majority of infants had right-biased movement behaviors. Multiple subsystems, rather than a single asymmetric system, appeared to control asymmetric action of different body regions. There were sex differences in asymmetry of distal lower body movement behaviors that…
