Results suggested that once a performance-equated age range of nonretarded Ss was isolated with parity to the mildly retarded standard, a number of nonretarded comparison groups, matched on a preestablished performance standard, may be consistently generated. (Author)

Movement-sequencing deficits and possible manual-performance asymmetries in right-handed adolescents and adults with Downs syndrome were examined. Although Ss with Down syndrome showed no hand differences in tapping performance, they evidenced the same transfer of training asymmetries as did Ss without Down syndrome, suggesting that both the Down…

Results indicated that Down's syndrome children are delayed in their language development compared to nonretarded children of the same developmental age. This language delay appears to be related to deficiencies in vocal imitation skills but is not related to general sensorimotor functioning. (Author)

As part of a longitudinal study, home observations were made of 14 Down Syndrome and 19 nonretarded infants at 6.5 months and 17 months. Findings stressed the importance of early compensatory training involving Down Syndrome infants and their parents in the home environment. (CL)

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)

The contributions of specific motor-coordination disabilities and general slowness of motor function to the choice reaction times (RTs) of 22 mildly retarded adults were examined in two experiments. (Author)

Motor skill acquisition of 12 Ss with Down syndrome on a pursuit tracking task was compared to retarded Ss without Down syndrome and nonretarded Ss matched for functional age and chronological age (CA). Ss with Down syndrome did not respond to directional probability in the same manner as retarded or nonretarded Ss. (Author/CL)

The relative effects of individualized sensory integrative therapy vs small group, gross motor programs were examined with 44 handicapped preschoolers with motor delays. No significance between group differences were observed in gross motor gains or in sensorimotor gains. (Author/CL)

The relative effectiveness of multisensory-, physical-, modeling-, and verbal-prompting assessment strategies upon the gross motor performance of 40 moderately retarded children (ages 5 to 15 years) was investigated, taking into account the impact of the Ss' levels of reflexive maturation and orthopedic functioning.

A critique is presented of a study by R. Neman, et al. (1975) in which a sensorimotor training method of treatment for retarded children was evaluated. (Author/GW)

The E. Zigler and V. Seitz (1975) critique was carefully examined with respect to the conclusions of the R. Neman et al. (1975) study on the efficacy of a sensorimotor training program for retarded children. (Author/GW)
