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 ch...

Knowledge about aging of perceptual-motor skills is based almost exclusively on cross-sectional studies. We examined age-related changes in the retention of mirror-tracing skills in healthy adults who practiced for 3 separate days at baseline and retrained 5 years later at follow-up. Overall, the speed and accuracy of an acquired skill were partially retained after a 5-year interim, although th...

The purpose of this study was to analyze the nature of the coordination evolution during the process of learning a gross motor skill. Participants had to learn to oscillate as smoothly as possible on an experimental swing during 10 sessions of 10 trials. Using tools and methods of dynamical systems theory, two qualitatively different coordination modes were observed during learning. The change ...

abstract objective development is a complex process, completed over a specific period of time, through the maturation of the nervous system. it is affected by genetic, ethnic, nutritional, social, and economic factors; one of the environmental factors affecting the acquisition of motor skills in infants is the use of baby walkers. since this device is very commonly used for infants in our count...

[Purpose] The purpose of this study was to examine the gross motor skill development of 5-year-old Kindergarten children in Myanmar. [Subjects and Methods] Total 472 healthy Kindergarten children (237 males, 235 females) of 2016-2017 academic year from four schools in urban area and four schools in rural area of Myanmar were recruited. The gross motor skill development of all subjects was asses...

the purpose of this study was to investigate the effect of perceptual – motor experience on motor development quotient of fine and gross motor skills in infants. fifteen 5-8-month-old healthy infants participated randomly in this study and were divided homogenously into two groups (experimental and control) according to their age. experimental group had 36 training sessions, each session an hou...

the purpose of this study was to investigate the effect of a selected motor program (as a motor experience) on manipulative skills in 4-6-year-old boys. 40 subjects were selected randomly using a personal information questionnaire. after the pretest, the ulrich's test of gross motor development (2000) including fundamental motor skills, locomotors skills, manipulative skills and controllin...

This study examined motivational effects of feedback on motor learning. Specifically, we investigated the influence of social-comparative feedback on the learning of a balance task (stabilometer). In addition to veridical feedback (error scores reflecting deviation from the target horizontal platform position) about their own performance after each trial, two groups received false normative inf...

This study examined the acquisition and long-term retention of a gross motor skill, namely, tossing, in 23 moderately to severely demented Alzheimer's disease (AD) patients and 22 health older adults. To identify optimal learning strategies, subjects received 10 weeks of training under either constant or variable practice conditions. Accuracy at the tossing task was assessed immediately, one we...

OBJECTIVE This study investigated the effects of qualitative and quantitative knowledge of results (KR) on the acquisition of a motor skill. It was hypothesized that there would be differences in performance during skill acquisition and retention, depending on the type of feedback given. Qualitative KR was in the form of verbal encouragement and quantitative KR was in the form of an algebraic n...
