The purpose of this study was to examine the effect of massed and distributed practice upon the learning by 8 autistic children of rotary pursuit tracking at 20 rpm. The massed practice group of four completed 10 30-sec. trials with 5-sec. rests for 10 consecutive days on the Photoelectric Pursuit Rotor. The distributed practice group completed 10 30-sec.(More)
To determine the influence of two forms of visual control techniques and one kinesthetic technique on putting accuracy 27 right-handed female volunteers performed a putting task under one of three testing conditions: eyes on ball, eyes on target, and no vision. Three putting distances of 5, 10, and 15 ft. were employed. The results of a 3 (conditions) x 3(More)
ICTCP is a colour difference signal representation recently standardized in Rec. ITU-R BT.2100. One design criteria of ICTCP for HDR/WCG imagery is to address issues in Non-Constant Luminance (NCL) Y'CbCr with HDR/WCG signals. In this paper, the superior performance of ICTCP in preserving constant luminance over the NCL Y'CbCr is analyzed in detail. The(More)
This study investigated the correlation among measures of perceptual-motor abilities, self-concept, and reading achievement and determined whether perceptual-motor ability and self-concept can predict reading achievement in the early elementary grades. A total of 105 boys and 108 girls from the first, and second and third grades were tested on the(More)
The purpose of the present study was to examine the potential of a multivariable approach in predicting dental motor skill performance. Variables measuring cognitive knowledge, motor abilities, educational background, and family demographics were examined. Data were obtained from 33 first-year dental students. Scaling and root planing tests were(More)
