Background: Learning disability is one of the most noticed subjects for behavioral specialists. Most of the learning difficulties are caused by senso-motor development and neurological organization. The main purpose of the present research is to examine the role of delayed perceptual-motor development and brain damage in origination of expressive writing disorder (EWD).   Methods: The studi...

Motor learning often involves situations in which the somatosensory targets of movement are, at least initially, poorly defined, as for example, in learning to speak or learning the feel of a proper tennis serve. Under these conditions, motor skill acquisition presumably requires perceptual as well as motor learning. That is, it engages both the progressive shaping of sensory targets and associ...

Performance on perceptual-motor (PM) tasks should not be affected by cognitive workload (CW). Subjects performed a novel task that combined a ”recall” version of the n-back task and a PM distractor task. Subjects’ performance was significantly worse on the PM task when CW was increased. As CW was manipulated, the perceptual and motor requirements of both the n-back task and the PM task remained...

Two studies were carried out in order to better understand the role of perceptual and visuo-motor skills in handwriting. Two training programs, visual-haptic (VH) and visual (V), were compared which differed in the way children explored the letters. The results revealed that improvements of VH training on letter recognition and handwriting quality were higher than improvements after V training....
