The primary motor cortex (M1) is crucial for motor skill learning. We examined its role in interleaved practice, which enhances retention (vs. repetitive practice) through M1-dependent consolidation. We hypothesized that cathodal transcranial direct current stimulation (ctDCS) to M1 would disrupt retention. We found that ctDCS reduced retention…

Background: Laparoscopic cholecystectomy (LC) is one of the most frequently performed surgical procedures worldwide with occasional serious complications, including bile duct injuries, that may reflect surgeon misperception, rather than errors of skill and knowledge. Intraoperative cholangiography (IOC) is an imaging procedure that may prevent or…

Objective: Measurement tools for children's foundational skills provide important insights towards the developmental mechanisms of these domains. This study examines the structure of sensorimotor, visuospatial processing (VP), executive function (EF) skills and their interrelationship. The NEPSY is a widely-used neuropsychological instrument, but…

Task trainer simulators are often used in medical programs for bachelor's degree students when teaching procedural skills. They provide the opportunity to practice dangerous maneuvers that students are not ready to perform on real patients yet. The rise of technology has vastly expanded the availability of these devices for use in teaching. To…

The aim of this study was to develop a badminton teaching system using the wearable technology for improving badminton teaching and learning. This system can provide the similarity scores automatically by comparing a student's movement and strength while playing badminton with a well-trained expert model. A quasi-experiment was conducted for eight…

In their seminal study of chess expertise, Simon and Chase (Chase & Simon, 1973; Simon & Chase, 1973) proposed that perceptual learning was a necessary component of skill acquisition. In their view, acquisition of skill results from the strategic use of learning at multiple levels to adaptively overcome inherent limitations. The knowledge…

South Australian, Lyndall Hendrickson AM (1917-2017) led a lifetime of achievements as a prodigy, concert violinist, polio survivor, violin instructor and teacher of language and music to non-verbal autistic students. Her career halted when she contracted poliomyelitis at the age of 34. To regain motor skill, Hendrickson researched theories of…

Examining age differences in motor learning using real-world tasks is often problematic due to task novelty and biomechanical confounds. Here, we investigated how children and adults acquire a novel motor skill in a virtual environment. Participants of three different age groups (9-year-olds, 12-year-olds, and adults) learned to use their upper…

Introduction: This article demonstrates the effectiveness of the use of routine-based instruction for teaching sensorimotor-stage object-perception skills to students who have visual impairments (i.e., blindness or low vision) and severe intellectual disabilities. Method: Classroom teachers documented progress toward achievement of object…

This study aims to reveal the problems faced by a dyslexic student in learning science and determine what can be considered an effective science teaching method for this kind of learner. The case study design was used, and the study was conducted with a 7th-grade dyslexic female student. This study used observations and a semi-structured interview…

In the learning support for repetitive motions having an operating instrument, it is necessary for learners to control not only their own body motions but also an instrument corresponding to the body. This study focuses on the repetitive motion learning using single operation instrument without the movement in space; i.e. jump-rope and hula-hoop.…

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…

Background: Under the view of dynamical system theory, expertise in sports emerges from the interaction of multiple constraints. At an individual level, important interactions amongst constraints could include the relationships that evolve between one's family, playmates/coaches, and specific training activities. Or more broadly, other…

Early research on visual imagery led investigators to suggest that mental visual images are just weak versions of visual percepts. Later research helped investigators understand that mental visual images differ in deeper and more subtle ways from visual percepts. Research on motor imagery has yet to reach this mature state, however. Many authors…

Some of the characteristics and behaviors of children with autism spectrum disorder (ASD), such as difficulty with social interactions and sensory integration, make physical education instruction difficult. Children with ASD also encounter movement difficulties, such as motor-planning and anticipatory deficits. One way to enhance the ability of…
