Implicit motives like the need for power (nPower) scale affective responses to need-specific rewards or punishments and thereby influence activity in motivational-brain structures. In this paper, we review evidence specifically supporting a role of the striatum in nPower. Individual differences in nPower predict (1) enhanced implicit learning accuracy, but not speed, on serial-response tasks th...

This paper presents an experiment to determine the underlying learning mechanism by which shared control with error reduction improves training effectiveness for dynamic manual control tasks in virtual environments. Specifically, the authors test the hypothesis that the learning mechanism of shared control with error reduction is through demonstration of the preferred strategy in the early phas...

The relationship between the brain and the environment is flexible, forming the foundation for our ability to learn. Here we review the current state of our understanding of the modifications in the sensorimotor pathway related to sensorimotor learning. We divide the process into three hierarchical levels with distinct goals: (1) sensory perceptual learning, (2) sensorimotor associative learnin...

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...
