The use of primes, contingent attention, and training sessions to assess a child's engagement and skill in six large motor activities was examined using a combination reversal and multiple-baseline design. Assessment was based on four levels: proximity to equipment, touching equipment, unskilled participation, and skilled participation. Before training, priming (suggestion to the child) was more effective than contingent attention for increasing the subject's engagement (but not skill) in five activities and for increasing skilled participation in one activity. Training of four activities in the natural environment effectively increased the subject's skill level in five activities. Thus, training appeared to generalize to one of these five activities in this setting and also to skillfully executed stair climbing in an adjoining setting. After training, primes and contingent attention were sufficient to maintain both the subject's skill level and engagement in all activities. Postchecks in the same setting the following semester with different teachers revealed only slight increases in participation, as compared to previous baselines, but all participation was at the skilled level. Social interaction, which was not experimentally manipulated, did not systematically vary in relation to changes in experimental conditions. 相似文献

This article discusses the role developmental dyspraxia plays in developmental coordination disorder (DCD), based upon a review of literature on apraxia, developmental dyspraxia, and DCD. Apraxia and dyspraxia have often been equated with DCD. However, it is argued that apraxia and dyspraxia primarily refer to the problems of motor sequencing and selection, which not all children with DCD exhibit. The author proposes to distinguish developmental dyspraxia from DCD. Other issues discussed include the assessment, etiology, and treatment of developmental dyspraxia and DCD, and the relationship between DCD and learning disabilities. A research agenda is offered regarding future directions to overcome current limitation. 相似文献

A total of 128 male and female university students having Swedish as their mother tongue rated 439 actions on a 7-point scale in the dimensions of Familiarity, Emotionality, Motor Activity, and Memorability under instructions to imagine themselves performing each action (e.g., “to roll a ball”, “to break a match”). Overall mean ratings were higher for women than for men in all four dimensions. High reliabilities were obtained in each scale. Intercorrelations between the dimensions were low to moderate, indicating that different characteristics of the actions were assessed. It is demonstrated that the ratings of the four dimensions are in agreement with previous categorisations of actions along the same or similar dimensions and with findings related to memory performance. Furthermore, control studies performed on the Familiarity dimension show that norm values are highly correlated with ratings given by participants in standard enacting and nonenacting conditions and with ratings in a condition where objects were present. These norms offer possibilities to control for and vary item characteristics of importance in the study of actions and the memory of actions. 相似文献

This investigation was conducted to determine whether the strong seasonality effect on infant motor development that has been noted in moderate climates would be replicated with infants born in a geographic region with more extreme conditions. One hundred and forty-five full-term infants (72 males, 73 females) born in Edmonton, alberta were assessed using the Alberta Infant Motor Scale (AIMS) at 7 months of age. No seasonality effects on the AIMS total scores or the prone, supine, sitting, or standing subsection scores were detected. A weak and statistically non-significant correlation was obtained between the average monthly AIMS scores and the average monthly temperatures 7 months after birth. These results suggest that extreme climatic conditions in urban geographic regions may dampen effects of season of birth on infant motor development. 相似文献

Although many follow-up studies have been performed on preterm infants, little attention has been devoted to prediction of motor skills in the preschool or school years. We studied the relationship of performance on the Bayley Scales of Infant Development at a mean corrected age of 21 months to performance on the McCarthy Scales of Children's Abilities at a mean corrected age of 44.7 months for 43 appropriate-for-gestational-age (AGA) children born at ≤ 32 weeks gestation. Motor scores were stable over time with a significant correlation between the Bayley Psychomotor Developmental Index (PDI) and the McCarthy Motor subscale (r = 0.60; p = 0.0001). Scores of cognitive abilities also showed a significant correlation between the Bayley Mental Developmental Index (MDI) and the McCarthy General Cognitive Index (r = 0.42; p = 0.009). Small-for-gestational-age (SGA), very low-birthweight (≤ 1500 grams) children scored lower on the McCarthy General Cognitive Index (p = 0.01) and on the Motor subscale (p = 0.047) than the AGA children. We concluded that motor performance of AGA children born at ≤ 32 weeks gestation is stable from toddlerhood to preschool age. We suggest that SGA children be excluded from studies of motor performance of prematurely born children. 相似文献

This article surveys the extant literature on mental imagery as used in athletics for performance enhancement, arousal regulation, affective and cognitive modification, and rehabilitation. For each category of use, applications are discussed, an overview of the empirical and case-study research findings is presented, and the research is critiqued. A concluding section recommends directions for future research on uses of mental imagery in athletics. 相似文献

This study was designed to investigate the possibilities that subjects would visualize an auditory contour as a visual contour (visual imagery) to encode pitch information of tone sequences (Experiment 1), and that subjects would be motivated to attempt to engage in covert rehearsal with multi-code (Experiment 2). The findings from these experiments suggest that: (a) Whereas the highly musically trained subjects were able to encode pitches as accurate notes on a staff, the less well musically trained subjects encoded the pitch sequence as a contour. It is quite evident that there is an intermodal analogy between the perception of pitch relationships and that of relationships in visual space. (b) Pitch rehearsal of auditory information along with note names (dual-code) and staff notation accompanied by pitch rehearsal with note names (triple-code) were the most effective strategies for highly trained subjects with pitches of tonal sequences; melodic contour accompanied by pitch rehearsal (dual-code) was used by highly trained subjects with atonal sequences and by less well trained subjects with both types of sequences. 相似文献

中文读写能力及其相关因素研究 总被引:7,自引:0,他引:7
使用5点量表,本研究在北京地区调查了2187名小学一、三、五年级儿童的中文读写能力及其相关因素。因素分析抽取了8个因素:书面语意义理解、基本知觉能力、书写技能、家庭阅读背景、动作技能、口语能力、朗读和听写、书面表达。对上述因素进行多元逐步回归分析发现,各种读写能力内部相关显著。基本知觉能力、口语能力、家庭阅读背景和动作技能分别对中文读写能力的不同成分有显著解释作用。这个结果对于理解阅读能力发展及其与家庭阅读背景、口语、基本知觉一动作能力之间的关系,以及阅读障碍的内在机制具有重要的理论意义。 相似文献
