Motor learning plays an important role in upper-limb function and the recovery of lost functionality. This study aimed to investigate the relative impact of transcranial direct current stimulation (tDCS) on learning in relation to the left primary motor cortex (M1) and left dorsolateral prefrontal cortex (DLPFC) during bimanual isometric force-control tasks performed with both hands under different task constraints. In a single-blind cross-over design, 20 right-handed participants were randomly assigned to either the M1 group (n = 10; mean age, 22.90 ± 1.66 years, mean ± standard deviation) or the DLPFC group (n = 10; mean age, 23.20 ± 1.54 years). Each participant received 30 min of tDCS (anodal or sham, applied randomly in two experiments) while performing the bimanual force control tasks. Anodal tDCS of the M1 improved the accuracy of maintenance and rhythmic alteration of force tasks, while anodal tDCS of the DLPFC improved only the maintenance of the force control tasks compared with sham tDCS. Hence, tDCS over the left M1 and DLPFC has a beneficial effect on the learning of bimanual force control. 相似文献

This study investigated the impact of an adapted physical education training package on functional motor skill instruction of three special education teachers who instructed secondary students with low‐incidence disabilities. The training package emphasized teachers' use of systematic prompting and specific reinforcement teaching strategies plus adapted physical education consultation. We used a multiple baseline design and collected data on the three teachers' use of systematic prompting and specific reinforcement plans during videotaped teaching trials. We also collected data on how teachers documented their instructional strategies, and we analyzed personal reflections that teachers wrote in the journals. Results indicated that with each of the three teachers, correctly implemented functional motor skill instructional performance improved after they completed the training package. 相似文献

What incites infant locomotion? Recent research suggests that locomotor exploration is not primarily directed toward distant people, places, or things. However, this question has not been addressed experimentally. In the current study, we asked whether a room filled with toys designed to encourage locomotion (stroller, ball, etc.) elicits different quantities or patterns of exploration than a room with no toys. Caregivers were present but did not interact with infants. Although most walking bouts in the toy‐filled room involved toys, to our surprise, 15‐month‐olds in both rooms produced the same quantity of locomotion. This finding suggests that mere space to move is sufficient to elicit locomotion. However, infants' patterns of locomotor exploration differed: Infants in the toy‐filled room spent a smaller percent of the session within arms' reach of their caregiver and explored more locations in the room. Real‐time analyses show that infants in the toy‐filled room took an increasing number of steps per bout and covered more area as the session continued, whereas infants in the no‐toy room took fewer and fewer steps per bout and traveled repeatedly over the same ground. Although not required to elicit locomotion, moving with toys encouraged infants to travel farther from their caregivers and to explore new areas. 相似文献

We investigated the development of a recently identified white matter pathway, the frontal aslant tract (FAT) and its association with executive function and externalizing behaviors in a sample of 129 neurotypical male and female human children ranging in age from 7 months to 19 years. We found that the FAT could be tracked in 92% of those children, and that the pathway showed age‐related differences into adulthood. The change in white matter microstructure was very rapid until about 6 years, and then plateaued, only to show age‐related increases again after the age of 11 years. In a subset of those children (5–18 years; n = 70), left laterality of the microstructural properties of the FAT was associated with greater attention problems as measured by the Child Behavior Checklist (CBCL). However, this relationship was fully mediated by higher executive dysfunction as measured by the Behavior Rating Inventory of Executive Function (BRIEF). This relationship was specific to the FAT—we found no relationship between laterality of a control pathway, or of the white matter of the brain in general, and attention and executive function. These findings suggest that the degree to which the developing brain favors a right lateralized structural dominance of the FAT is directly associated with executive function and attention. This novel finding provides a new potential structural biomarker to assess attention deficit hyperactivity disorder (ADHD) and associated executive dysfunction during development. 相似文献

Previous researches have shown that there was a strong relationship between fine motor skills and arithmetical abilities in children. However, the majority of previous studies examined only the correlations between fine motor skills and arithmetical abilities, but did not attempt to determine their causal relationship. Thus, the aim of the present study was to examine the effect of motor skills training on arithmetical abilities among 80 first graders. One of the results showed that the intervention group, which received training in fine motor skills for 10 min, showed greater improvements in performance on an arithmetic task and a pegboard than did the active control group, which read their favourite book for 10 min. These findings have suggested that training in this study is an appropriate program for improving fine motor skills and further fine motor skills had a significant influence on arithmetical abilities in children, with a medium effect size. The present study has, for the first time, provided evidence that there will be a causal relationship between these factors. 相似文献

In the present study, by using a briefly masked prime display paradigm, we investigated whether the pointing relation (same or different) between two unconsciously perceived arrows in the prime could be processed. Since only motor response priming can reflect unconscious processing of two arrows’ pointing-direction relation (i.e., a relational integration), we could distinguish the motor response priming from the visual priming in this study which in other studies were not separated. We also manipulated the prime-to-target stimulus onset asynchronies (SOA) by using a 70?ms and a 180?ms SOA. In this experiment, two masked arrow signs pointing in the same or different directions (> > or > <) were simultaneously presented in the prime, followed by two arrow symbols also pointing in the same or different directions in the target. The participants were asked to decide whether the two arrows in the target were pointing in the same or different directions. The results did not show any visual priming effect, but did show that the unconsciously perceived pointing relation in the prime elicited a positive motor response priming effect in RT under the 70?ms SOA condition, and a negative motor response priming effect in accuracy under the 180?ms SOA condition. The results were discussed in terms of self-motor-inhibition (or mask-triggered inhibition) and attention mechanisms. Overall, this study indicated that the pointing relation between the two subliminal arrows in the prime could influence the subsequent responses to the target and suggested that people can integrate unconsciously perceived information. 相似文献

The gain–loss model (GaLoM) is a formal model for assessing knowledge and learning. In its original formulation, the GaLoM assumes independence among the skills. Such an assumption is not reasonable in several domains, in which some preliminary knowledge is the foundation for other knowledge. This paper presents an extension of the GaLoM to the case in which the skills are not independent, and the dependence relation among them is described by a well‐graded competence space. The probability of mastering skill s at the pretest is conditional on the presence of all skills on which s depends. The probabilities of gaining or losing skill s when moving from pretest to posttest are conditional on the mastery of s at the pretest, and on the presence at the posttest of all skills on which s depends. Two formulations of the model are presented, in which the learning path is allowed to change from pretest to posttest or not. A simulation study shows that models based on the true competence space obtain a better fit than models based on false competence spaces, and are also characterized by a higher assessment accuracy. An empirical application shows that models based on pedagogically sound assumptions about the dependencies among the skills obtain a better fit than models assuming independence among the skills. 相似文献

Phonological development is sometimes seen as a process of learning sounds, or forming phonological categories, and then combining sounds to build words, with the evidence taken largely from studies demonstrating ‘perceptual narrowing’ in infant speech perception over the first year of life. In contrast, studies of early word production have long provided evidence that holistic word learning may precede the formation of phonological categories. In that account, children begin by matching their existing vocal patterns to adult words, with knowledge of the phonological system emerging from the network of related word forms. Here I review evidence from production and then consider how the implicit and explicit learning mechanisms assumed by the complementary memory systems model might be understood as reconciling the two approaches. 相似文献

This study's purpose was to analyze the effects of aging on motor control, with a specific focus on analyzing the characteristics of motor inhibition failure. A continuous‐response task was conducted with 35 younger adults and 35 older adults, under several conditions and using two types of switches. The results indicated the following: (a) in older adults, response type and auditory stimuli strongly affected motor inhibition failure, and (b) in younger adults, motor inhibition failures rarely occurred. When they did occur, they were strongly affected by factors directing visual stimuli. These results suggest age‐related differences in variables that affect motor inhibition, and that movement and the associated nervous excitation might strongly affect motor inhibition in older adults. 相似文献

We evaluated a preliminary method for examining the antecedent and consequent contributions to noncompliance exhibited by two children with disabilities. In Phase 1, we assessed whether noncompliance was a result of a skill deficit. For one participant, we then conducted a functional analysis to determine the variables maintaining noncompliance in Phase 2. In Phase 3, we conducted a treatment evaluation to increase compliance for each participant. We identified the antecedent and consequent variables responsible for noncompliance and developed an effective intervention for both participants. 相似文献
