We argue that 4 fundamental gestalt phenomena in perception apply to the control of motor action. First, a motor gestalt, like a perceptual gestalt, is holistic in the sense that it is processed as a single unit. This notion is consistent with reaction time results indicating that all gestures for a brief unit of action must be programmed prior to…

Ten normally speaking children, 10 having mild misarticulations, and 10 having severe misarticulations, aged seven-eight, were administered unisensory and bisensory processing tasks. Results showed that misarticulating children obtained lower scores than normal children on all bisensory tasks and had larger decrements from unisensory to bisensory…

Investigates developmental changes in the accuracy of aimed movements made to an illuminated target lamp by children between the ages of 1.5 and 8 years. Shows accuracy decreased with decreasing availability of visual information and improved with age under all conditions. (HOD)

Children and adults were tested on six speeded perceptual-motor and cognitive tasks, including a (1) response time task; (2) button tapping task; (3) pegboard task; (4) coding task; (5) picture matching task; and (6) mental addition task. Age-related change in processing time on most of these tasks was described by a single exponential function.…

The role of perceptual organization in motor learning is discussed, the literature is reviewed, and research findings are summarized. Measurement problems are discussed, including observations about motor skill learning. Four experiments are described which compare organized and random movement sequences. It is shown that organization (whether…

Examined perception of object unity in partial occlusion in 72 infants. Recorded how long subjects looked at a display of complete and incomplete rods. In test and control conditions, infants looked longer at broken rods than at complete rods, suggesting that infants' cognitive, visual, or attentional skills may be insufficient to support…

The purpose of this paper was to relate Jean Piaget's stages of the learning process to the developmental aspects involved in reading comprehension. The need to correlate the developmental stage of the child's mind with the right types of activities was stressed. When a child has succeeded in the task of relating knowledge and affect to language…
