In contrast to previous findings, this study demonstrates that 11-month-old infants are able to learn the relationship between object material and object weight when exploring different objects that provided a systematic covariation of both object features. This guides their action in a subsequent preferential-reaching task. 相似文献

Children with impaired motor coordination (or Development Coordination Disorder – DCD) have difficulty with the predictive control of movements, evidenced by cross-sectional studies that show impaired motor imagery and action planning abilities. What remains unclear is whether this deficit in predictive control reflects immaturity of the motor system (a developmental delay) or some deviation from normal development (a disorder). To advance this discussion the present study used a longitudinal design to examine the development of motor imagery and action planning in children with DCD. Thirty children were included in the DCD group (aged 6–11 years) and age- and gender-matched to 30 controls. The DCD group had a mABC-2 score ≤ 16th percentile, the control group > 20th percentile. Motor imagery was assessed with the hand rotation task, action planning with a test for end-state comfort. Children participated in three measurements, with one year in between measurements. Results showed that children with DCD were slower and less accurate than their typically developing peers in all subsequent years but were able to improve their motor imagery ability over time. Furthermore, children with DCD showed less planning for ESC at the start of the present study, but were able to catch up with their peers during two-year follow up. These results exemplify that improvement of motor imagery and action planning ability is possible in DCD, and they lend theoretical support to the use of new training techniques that focus on training motor imagery to improve motor skills in children with DCD. 相似文献

以山东省济南市、莱州市的935名初二和高一学生为被试, 进行为期一年半的追踪研究, 考察了家庭社会经济地位与青少年的教育规划和职业规划之间的关系, 检验了外向性在其中的调节作用及其性别差异。结果表明:(1)家庭社会经济地位能够显著正向地预测青少年T1和T2时的教育规划以及T1时的职业规划;(2)外向性水平越高, 青少年教育规划和职业规划水平越高, 但是这种预测作用不存在长期性;(3)外向性能够调节家庭社会经济地位与青少年教育规划之间关系, 且这种调节作用存在显著的性别差异;但在家庭社会经济地位与青少年职业规划之间不存调节作用。这表明, 外向性不仅能够直接保护青少年的未来规划, 而且能够抵抗低家庭社会经济地位对个体未来规划的不良影响, 但是这种压力抵抗效应在不同性别、不同未来规划的领域之中存在差异。 相似文献

大学毕业生面临重要的生活转折, 其个人目标自主性对未来的无望感有显著影响。本研究以192名大四毕业生为被试, 采用特殊目标测量法考察个人目标自主性, 用问卷评价社会支持与无望感, 探讨目标自主性与无望感的关系, 并分析社会支持和性别的作用。结果发现:(1)毕业前夕去向已经确定的大学生, 无望感更低;(2)大四毕业生目标自主性越高, 对未来的无望感越低;(3)目标自主性对无望感的预测受到性别因素调节。对于男生, 高目标自主性能够显著降低无望感;对于女生, 目标自主性对无望感的预测作用不显著;(4)社会支持对于目标自主性与无望感之间的关系没有显著的调节作用, 但是社会支持越高, 其无望感越低。由此可见, 大学毕业生建立自主的个人目标和改善社会支持对降低无望感具有重要意义, 目标自主性的效应对男生尤为明显。 相似文献

Conditional goal setting is the tendency for people to see attainment of their future personal goals as necessary for their well-being. It has been argued that this represents an unhealthy way of relating to one’s goals, as well as being particularly problematic when goals are perceived as unlikely. High conditional goal setting has been found to be related to depression and to hopelessness. The present study examined conditional goal setting in deliberate self-harm, where problematic thinking about the future is very prominent. A group of individuals attending hospital for a recent episode of deliberate self-harm (N = 25) were compared with controls attending hospital for minor injuries (N = 25) as well as a psychologically disordered but non-suicidal control group (N = 25). Participants generated goals and rated goal likelihood, the extent to which those goals were seen as necessary for their future well-being (conditional goal setting), and also the extent to which the goals were seen as sufficient for their future well-being (goal sufficiency). Deliberate self-harm patients showed a higher degree of both conditional goal setting and goal sufficiency than did both of the other groups, further confirming the idea of painful engagement with personal goals, rather than disengagement, as characterising deliberate self-harm. 相似文献

The Quality Function Deployment (QFD) is an approach that facilitates designing product by analyzing and projecting the Customer's Needs (CNs) in the Engineering Characteristics (ECs) of a product. The aim of QFD planning process is to determine the target levels for ECs of a product that achieve high level of overall customers' satisfaction. However, integrating design team's preferences in this preliminary stage of product design could make the design more realistic and could also avoid unfeasibility in posterior phases of the product development processes. Moreover, this process is performed within an imprecise environment, and more than one factor must be taken into account in determining targets levels of ECs; especially, the limited resources and increased market competition. This paper presents an imprecise goal programming approach to determine the best aspiration levels of ECs in QFD planning process. Based on benchmarking data of ECs, the concept of satisfaction functions will be utilized to integrate explicitly the design team's preferences and incorporate the competitive analysis of target market into the modelling and solution processes. In addition, the relationships linking CNs and ECs and the ECs to each other are integrated by functional relationships. The proposed approach will be illustrated through an example of product development of an emulsification dynamite packing machine. Copyright © 2011 John Wiley & Sons, Ltd. 相似文献

In this paper, consumers' choice of brand constellations (eg Big Mac and Coke at McDonald's) are investigated by examining the roles of individual brands. The author proposes that marketers need to look beyond perceived fit between brands within a brand constellation. Therefore, this paper explores empirically how individual brand evaluations at product level and at brand level affect brand constellation choice. It is shown that brands do not have to be equally attractive in order to be included in brand constellations. For instance, a weak brand may complement a strong brand. Theoretical and marketing implications are discussed. Copyright © 2005 John Wiley & Sons, Ltd. 相似文献

Three studies evaluated Tier 1 early intervention for handwriting at a critical period for literacy development in first grade and one study evaluated Tier 2 early intervention in the critical period between third and fourth grades for composing on high stakes tests. The results contribute to knowledge of research-supported handwriting and composing instruction that informs practice as school psychologists are empowered to embrace the role of intervention specialist. The first study found that neurodevelopmental training (orthographic-free motor activities and motor-free orthographic activities) led to improved accuracy and legibility of letter formation, but that direct handwriting instruction with visual cues and verbal mediation led to improved automatic handwriting (rate of writing legible letters) and transfer to improved word reading. The second study found that neither motor training nor orthographic training alone added value to direct instruction in automatic letter writing and composing practice in developing handwriting skills, which transferred to improved word reading; but the added motor training did improve performance on a grapho-motor planning task for sequential finger movements that is relevant to composing. A related analysis showed that direct instruction with visual cues and memory delays may reduce reversals. A third study found that adding handwriting to reading instruction improved handwriting but did not add value to reading outcomes for at risk readers; reading instruction alone was beneficial for word reading, decoding, and comprehension. The fourth study showed that comprehensive, explicit instruction in the processes of composition led to more significant improvement, based on group and individual data, than did the regular fourth grade program, on high stakes writing assessment. 相似文献
