The development of children's rule use on the balance scale task   总被引:6,自引:0,他引:6  
Cognitive development can be characterized by a sequence of increasingly complex rules or strategies for solving problems. Our work focuses on the development of children's proportional reasoning, assessed by the balance scale task using Siegler's (1976, 1981) rule assessment methodology. We studied whether children use rules, whether children of different ages use qualitatively different rules, and whether rules are used consistently. Nonverbal balance scale problems were administered to 805 participants between 5 and 19 years of age. Latent class analyses indicate that children use rules, that children of different ages use different rules, and that both consistent and inconsistent use of rules occurs. A model for the development of reasoning about the balance scale task is proposed. The model is a restricted form of the overlapping waves model (Siegler, 1996) and predicts both discontinuous and gradual transitions between rules.  相似文献

临床决策的基本思路   总被引:3,自引:3,他引:0  
临床决策是临床工作的科学规划和策略抉择。其范畴包括管理、科研、教学和医疗。诊断决策应遵循6个步骤:资料的收集、甄别、分类、分析、判断和验证;思路方法上要正确处理现象与本质、局部与整体、共性与个性、静态与动态等4个关系。治疗决策应从性质与目的、治本与治标、中医与西医、总体与个体、病理与心理、医生与病人、效果与效价等7个方面提出科学可行的原则和措施。  相似文献

以34名五年级儿童为被试,采用出声思维法考查了阅读材料类型和难度对儿童阅读策略使用情况的影响。结果发现,被试在记叙文阅读过程中使用的阅读策略种类数和总次数均多于说明文。阅读材料难度对于阅读策略种类数和使用次数没有影响。阅读材料类型和难度都对多个阅读策略的使用次数有影响,但是阅读材料类型和难度对于各阅读策略使用次数的影响并不一致。  相似文献

How, and how well, do people switch between exploration and exploitation to search for and accumulate resources? We study the decision processes underlying such exploration/exploitation trade-offs using a novel card selection task that captures the common situation of searching among multiple resources (e.g., jobs) that can be exploited without depleting. With experience, participants learn to switch appropriately between exploration and exploitation and approach optimal performance. We model participants' behavior on this task with random, threshold, and sampling strategies, and find that a linear decreasing threshold rule best fits participants' results. Further evidence that participants use decreasing threshold-based strategies comes from reaction time differences between exploration and exploitation; however, participants themselves report non-decreasing thresholds. Decreasing threshold strategies that “front-load” exploration and switch quickly to exploitation are particularly effective in resource accumulation tasks, in contrast to optimal stopping problems like the Secretary Problem requiring longer exploration.  相似文献

This paper explores the ways in which national governments address the social inclusion of disadvantaged and disenfranchised groups in official strategy documents of the state. Data for this study come from a corpus of four key government strategy papers concerning Roma inclusion published by the Romanian Government between 2001 and 2015. This paper specifically looks at the ways in which strategy documents frame the problem of “crime” in the context of Roma inclusion. Texts were analysed using a critical frame analysis approach complemented by insights from discursive research. The findings highlight that although generally government policy on the Roma adopts and promotes a progressive/liberal agenda that aligns with EU strategic goals, pronounced ambivalence towards Roma people and subtle forms of racism are still present and persist.  相似文献

Peter Carruthers argues that the global workspace theory implies there are no facts of the matter about animal consciousness. The argument is easily extended to other cognitive theories of consciousness, posing a general problem for consciousness studies. But the argument proves too much, for it also implies that there are no facts of the matter about human consciousness. A key assumption is that scientific theories of consciousness must explain away the explanatory gap. I criticize this assumption and point to an alternative strategy for defending scientific theories of consciousness, one that better reflects the ongoing scientific practice. I argue there are introspectable inferential connections from phenomenal concepts to functional concepts that scientists can use to individuate the global workspace in terms of capacities that animals and humans share.  相似文献

The purpose of this study was to explore the level of inter- and intra-individual variability in the kinematic profiles of the back squat movement among skilled weightlifters. Ten competitive weightlifters volunteered for participation in this study. Barbell velocity (VBarbell) and angular velocity of the ankle (ωAnkle), knee (ωKnee) and hip joint (ωHip) were obtained by kinematic recording of six trials at 90% of 1RM in the back squat. Inter-individual variability was assessed by analysing inter-individual differences in the velocity curves through the statistical parametric mapping method. Intra-individual variability was assessed through a correlation analysis between the barbell velocity curves of each trial for each participant. Partial least squares regression analysis, was performed to relate changes in intra-individual variability to movement and anthropometric characteristics. Significant inter- and intra-individual differences were identified in VBarbell, ωAnkle, ωKnee, and ωHip (p ≤ 0.05). Having a short trunk and thigh, and a long shin in combination with greater anterior-posterior displacement of the barbell and slower velocities during the acceleration phase increased intra-individual movement consistency over movement variability. The results of the present study clearly demonstrate that skilled weightlifters display both significant inter- and intra-individual variability in the successful execution of the back squat.  相似文献
