Visual tracking of multiple objects in a complex scene is a critical survival skill. When we attempt to safely cross a busy street, follow a ball's position during a sporting event, or monitor children in a busy playground, we rely on our brain's capacity to selectively attend to and track the position of specific objects in a dynamic scene. This…

Learning effects were assessed for the block design (BD) task, on the basis of variation in 2 stimulus parameters: perceptual cohesiveness (PC) and set size uncertainty (U). Thirty-one nonclinical undergraduate students (19 female) each completed 3 designs for each of 4 varied sets of the stimulus parameters (high-PC/high-U, high-PC/low-U,…

Results of this study suggest that Negro mentally retarded children are more proficient on sensory motor tasks than are their white counterparts. (Author/MG)

Supports the hypothesized distinction between Mongol children's visual-motor performance and their correctly perceiving visual designs. (Author/RL)

An argument centered on perceptual-motor training as an educational fad and a criticism of training approaches. Paper presented at the annual meeting of the American Orthopsychiatric Association (New York, New York, 1969). (RJ)

Assessed were the abilities of 50 normal 5-to 9-year-old children and 30 learning disabled 7-to 9-year-old children to recognize temporal patterns presented visually and auditorially (intramodal abilities) and to vocally produce the patterns whether presentation was visual or auditory (intramodal and cross-modal abilities).

THIS VOLUME PRESENTS NORMATIVE DATA AND INSTRUCTIONS FOR ADMINISTERING AND SCORING THE PURDUE PERCEPTUAL MOTOR SURVEY (PPMS). THE FINDINGS OF SEVERAL INVESTIGATORS ARE NOTED IN ESTABLISHING A RATIONALE FOR PERCEPTUAL MOTOR ACTIVITIES IN CHILDREN. MOTOR ACTIVITY IS DISCUSSED IN TERMS OF GENERALIZED MOVEMENT, REFLEX ACTIVITIES, MOVEMENT PATTERNS,…

THIS STUDY WAS CONDUCTED TO INVESTIGATE THE EFFECTS OF VARIATIONS IN THE SPEED AND DIRECTION OF A FLYING OBJECT ON VISUO-PERCEPTUAL JUDGMENTS MADE, DIFFERENCES IN THE ABILITY OF SKILLED AND UNSKILLED SUBJECTS IN MAKING SUCH JUDGMENTS, AND THE EFFECTS OF AGE OR MATURITY LEVEL ON THE SPEED AND ACCURACY OF SUCH JUDGMENTS. THE SUBJECTS WERE 54 MALE…

A study investigated the recall of terminal location and distance of both preselected and constrained movements. Systematic alteration of the magnitude and direction of the starting position for recall movements revealed that the distance moved significantly interfered with the recall of the terminal location, but that distance was usually…

This study explored the relationships among age, gender, depth of sport experience, and coincidence anticipation performance for 42 children 3- to 9-year-old from high middle and socioeconomic backgrounds. The task involved observing light illumination moving down the track of a Bassin Timer. Depth of sport experience was evaluated by the amount…

The investigation, which involved 55 learning disabled and 54 normal children (mean age seven years), was designed to test the hypothesis that differences between these groups on tests of perceptual functioning are not educationally significant. (Author/SBH)

This study investigated the subtest items included in Cratty's body perception tests for children classified as educable mentally retarded or otherwise developmentally disabled. (JD)
