The ability to adjust movements in response to perturbations is key for an efficient and mature nervous system, which relies on two complementary mechanisms -- feedforward adaptation and feedback control. We examined the developmental trajectory of how children employ these two mechanisms using a previously validated visuomotor rotation task,…

Purpose: This study examined how speakers adapt to fundamental frequency (f[subscript o]) errors that affect the use of prosody to convey linguistic meaning, whether f[subscript o] adaptation in that context relates to adaptation in linguistically neutral sustained vowels, and whether cue trading is reflected in responses in the prosodic cues of…

Speech problems affect about 66% of children with classic galactosemia (CG), but limited evidence is reported on early motor and sensory motor development in this at-risk population. Research has been focused on speech and language development, leaving a paucity of data on motor and sensory differences. This paper describes preliminary data…

Objectives: The aim of this study was to examine the combined effects of perceptual-motor exercises and vitamin D[subscript 3] supplementation on the reduction of stereotypical behavior in children with autism spectrum disorder (ASD). Methods: In this study, 100 eligible children with age ranging from 6 to 9 years were randomly selected and…

Objectives: The aim of the study is to distinguish between perceptuomotor and cognitive inflexibility as the source of set-switching difficulties in children with autism spectrum disorder (ASD). Methods: Seventeen adolescents with ASD and 17 neurotypical controls were presented with a computerized sequencing game using colored shapes. The sequence…

For children with moderate or severe cerebral palsy (CP), a foundational early goal is independent sitting. Sitting offers additional opportunities for object exploration, play and social engagement. The achievement of sitting coincides with important milestones in other developmental areas, such as social engagement with others, understanding of…

In the C-not-B task, 2.5-year-old children tend to look for an object in a location to which the hiding agent moved his hand (C) after moving an object from A to B. In three experiments, the authors investigated the nature of the constraints underlying toddlers' performance in this task. In Experiment 1, 2.5-year-olds were tested in a new version…

This qualitative study examines student musicians' perceptions of their performance and development resulting from Body Mapping (BMG) technique. BMG is a somatic (mind-body) education technique designed to teach musicians skills in self-evaluation and change for performing with sensory-motor integrity. A qualitative study guided by an…

This article notes the convergence of recent thinking in neuroscience and grounded cognition regarding the way we understand mental representation and recollection: ideas are dynamic and multi-modal, actively created at the point of recall. Also, neurophysiologically, re-entrant signalling among cortical circuits allows non-conscious processing to…

Background: The innate ability for typically developing children to attain developmental motor milestones early in life has been a thoroughly researched area of inquiry. Nonetheless, as children grow and are required to perform more complex motor skills in order to experience success in physical activity and sport pursuits, the range of…

Some types of automaticity can be attributed to simple stimulus-response associations (G. D. Logan, 1988). This can be studied with paradigms in which associations to an irrelevant stimulus automatically influence responding to a relevant stimulus. In 1 example, the irrelevant and relevant stimuli were presented successively with the 1st,…

Perceptual motor programs (PMPs) are used widely in Australian schools. This study reports on an analysis of the information about the uses and the rationales for these programs drawn from the websites of Australian schools. Wide-ranging claims are made for the benefits of these programs for students with difficulties and for typically developing…

Literature examining elements influencing the production of consistent human movement is reviewed in this paper. The review is limited to theoretical papers and research studies on sport-related tasks that utilize actual representations of movement, e.g., film, electromyogram, or videotape; rather than movement only implied from goal attainment,…

This study examined consequences of the comorbidity of developmental coordination disorder (DCD) and learning disability (LD) for the severity and pattern of perceptual-motor dysfunction. Compared to children with only DCD, those with DCD and LD had poorer perceptual-motor ability, with particular difficulty performing manual dexterity and balance…

An experiment to determine the effects of perceptual organization on learning and remembering a motor task is described. Four test groups received different methods of presentation of movements to be learned--sequential-sequential, sequential-random, random-sequential, and random-random. Analysis of variance was used to examine results. Results…
