Expert and exceptional performance are shown to be mediated by cognitive and perceptual-motor skills and by domain-specific physiological and anatomical adaptations. The highest levels of human performance in different domains can only be attained after around ten years of extended, daily amounts of deliberate practice activities. Laboratory analyses of expert performance in many domains such a...

[Purpose] The purpose of the current study was to compare the effectiveness of motor sequential learning according to two different types of practice schedules, distributed practice schedule (two 12-hour inter-trial intervals) and massed practice schedule (two 10-minute inter-trial intervals) using a serial reaction time (SRT) task. [Subjects and Methods] Thirty healthy subjects were recruited ...

The effects of advanced age and cognitive resources on the course of skill acquisition are unclear, and discrepancies among studies may reflect limitations of data analytic approaches. We applied a multilevel negative exponential model to skill acquisition data from 80 trials (four 20-trial blocks) of a pursuit rotor task administered to healthy adults (19-80 years old). The analyses conducted ...

We recently defined a component of motor skill learning as "motor acuity," quantified as a shift in the speed-accuracy trade-off function for a task. These shifts are primarily driven by reductions in movement variability. To determine the neural correlates of improvement in motor acuity, we devised a motor task compatible with magnetic resonance brain imaging that required subjects to make fin...

impulsivity features of individuals affect their movement patterns when learning sports skills. therefore, this study examined the effect of different levels of motor impulsivity on learning basketball basic skills. 3 groups of boys aged between 10 and 12 who were selected according to motor impulsivity levels participated in a basketball skills training course along with a control group (the s...

the purpose of this current study was to investigate the influence of perceptual-motor trainings on motor skills of girls with trainable mental retardation. so 20 girls with trainable mental retardation in the town of marivan welfare organization with the average of 8/3 ±1/11 years and iq of 39/14±6/84 with purposive sampling method were studied. all girls were pretested. then samples based on ...

Objectives: Sensory integration training plays a crucial role on the attention span and motor skills of students with Down syndrome. The present research aimed to investigate the effect of sensory integration training on the attention span and motor skills of students with Down syndrome.  Methods: This was a quasi-experimental research with a pretest, posttest design and control group. Partici...

Objectives: The aim of this study was to determine the effect of Perceptual-motor training on motor skills of normal preschool children (aged 4-6 years) in Esfahan city. Methods: This was a quasi-experimental study with intervention and control groups. Each group included 30 normal preschool children aged 4 to 6 years. They were selected randomly children of intervention group one empowering...

objective in this article, a motor skill disorder called developmental coordination disorder (dcd), that is usually first diagnosed during childhood, is explained and discussed. in the year 1987, dcd was formally recognized as a distinct disorder in children by the american psychiatric association  (apa). dcd is a generalized term for the children who have some degrees of impairment in the deve...
