“皮亚杰认知发展量表” (IPDT)中的守恒与关系领域经动态化改编后已被证实适用于小学低年级儿童的潜能评估。在此基础上, 本研究旨在构建适用于小学高年级儿童的IPDT表征、分类、规律领域的动态测验; 并运用所构建的IPDT动态测验对低社会经济地位(SES)儿童进行认知潜能评估; 而后经过对低SES儿童的推理认知干预, 进一步考查认知干预在低SES不同潜能儿童的认知能力和数学成就中的促进作用。结果发现:(1)改编的IPDT表征、分类、规律领域的动态测验包含“前测—干预—迁移—后测”4个阶段, 所构建的逐级提示干预方案合理适切, 可以有效区分不同认知潜能水平的小学高年级儿童, 特别是弱势儿童; (2)推理认知干预对由IPDT动态测验细致区分出的不同潜能水平的低SES儿童作用不同, 尽管他们在认知能力与数学成就上均有进步, 但低SES高潜能儿童比低SES低潜能儿童从干预中获益更多。 相似文献

绝大部分组织行为学研究都是从静态视角聚焦变量在一段时间内的整体平均水平, 而忽视了时间的角色, 如变量在一段时间内的动态变化特征。通过引入时间的角色, 从动态视角关注变量的动态变化特征并探讨其影响因素和结果, 可能为现有研究提供新的、突破性视角, 进而帮助拓展传统管理理论。鉴于其对理论发展的重要性, 近年来, 部分新近研究开始逐步关注时间的角色, 从动态视角探索变量的动态变化特征。然而, 整体来看, 这类研究仍相对较少, 且分散在不同的研究领域, 还未能形成结构化体系。基于此, 在将相关研究按照两个维度——变量的动态变化特征的类别(趋势 vs. 波动)与变量的动态变化特征的角色(自变量 vs. 因变量)分为四大类别后, 系统地回顾和梳理相关研究, 并厘清研究背后的理论机制。最后, 基于以上梳理分析, 未来研究可从关注变量的波动; 考察趋势、波动和整体平均水平等的交互作用等角度出发, 更加全面、系统地扩展组织行为学理论。 相似文献

Posttraumatic stress disorder (PTSD) frequently co-occurs with major depressive disorder, and empirically supported PTSD treatments consistently improve depression. However, both diagnoses are heterogeneous and specific patterns of symptom overlap may be related to worse treatment outcome. Two hundred individuals with chronic PTSD participated in a doubly randomized preference trial comparing prolonged exposure and sertraline. Latent Profile Analysis was used to identify classes based on PTSD and depression symptoms prior to starting treatment. A three-class model best fit the data, with a high depression and PTSD severity class (distressed), a moderate depression and low PTSD avoidance class (depressive), and a low depression and high PTSD avoidance class (avoidant). The avoidant class showed the lowest rates of major depressive disorder diagnosis and transdiagnostic vulnerabilities to depression. Patients in the distressed class experienced more robust PTSD treatment response, with no differences between prolonged exposure and sertraline. These findings highlight the role of avoidance in nondepressed PTSD presentations while also demonstrating that co-occurring depression is not contraindicated in evidence-based PTSD treatment. 相似文献

The first aim of this study was to identify long-term patterns of ethical organizational culture based on the perceptions of 368 Finnish managers over a period of two years. The second aim was to investigate whether there is a difference in the long-term occupational well-being (burnout and work engagement) of managers exhibiting different patterns of ethical culture. Based on latent profile analysis, five different patterns of the strength of ethical culture were identified: moderate, high, increasing, decreasing, and low. The results show that managers exhibiting either the low or decreasing pattern of ethical culture experienced significant changes in their well-being over time. Decreasing or permanently low ethical culture was related to increased cynical attitudes towards work, and to decreased work engagement. On the positive side, stably high ethical culture was associated with enduringly high levels of well-being over time. In sum, low or decreasing ethical culture poses a risk to occupational well-being, whereas an organization with a culture that is perceived as permanently strong represents a favourable work environment. 相似文献

In Europe, the use of electric bicycles is rapidly increasing. This trend raises important safety concerns: Is their use compatible with existing infrastructure and regulations? Do they present novel safety issues? How do they impact other traffic? This study sought to address these concerns, using instrumented electric bicycles to monitor e-cyclists’ behavior in a naturalistic fashion. Data was collected from 12 bicyclists, each of whom rode an instrumented bicycle for two weeks. In total, 1500 km worth of data were collected, including 88 critical events (crashes and near-crashes). Analysis of these critical events identified pedestrians, light vehicles and other bicycles as main threats to a safe ride. Other factors also contributed to crash causation, such as being in proximity to a crossing or encountering a vehicle parked in the bicycle lane. A comparison between electric and traditional bicycles was enabled by the availability of data from a previous study a year earlier, which collected naturalistic cycling data from traditional bicycles using the same instrumentation as in this study. Electric bicycles were found to be ridden faster, on average, than traditional bicycles, in addition to interacting differently with other road users. The results presented in this study also suggest that countermeasures to bicycle crashes should be different for electric and traditional bicycles. Finally, increasing electric bicycle conspicuity appears to be the easiest, most obvious way to increase their safety. 相似文献

采用问卷法,对764名青少年进行测试,首先采用潜在剖面分析模型探索了父母教养方式的潜在类别,然后通过青少年道德脱离、道德同一性的得分差异来确认潜在类别的效度。结果表明,从青少年的角度父母教养方式分为积极型、消极型和混合型三种,其中积极型人数最多、消极型人数最少。此外,青少年道德脱离、道德同一性的得分在这三种潜在类别上存在显著差异,表明本研究得到的三种潜在类别有较好的效度。积极型教养方式下青少年道德脱离的得分显著低于混合型和消极型的得分,混合型教养方式下道德脱离的得分显著高于消极型的得分;积极型教养方式下青少年道德同一性的得分显著高于混合型和消极型的得分,混合型教养方式下道德同一性的得分显著低于消极型的得分。 相似文献

In theoretical analyses of early mother–child interaction, it has been argued that interaction should be studied in its flow over time, and that the behaviour of each interactant is likely to be non‐linearly determined. The mother–child dyad can be seen as a non‐linear dynamic system, the development of which is determined by the mutual relations between its elements. The present study is based on the idea that computer simulations can be used to find out what kind of empirical implication these ideas have. Accordingly, we describe two non‐linear dynamic systems‐based models for simulating mother–child interaction, i.e. a connectionist network model and a logistic growth model. Three determinants of the nature of the interaction, i.e. the child's irritability, the mother's sensitive responsiveness, and the intensity of an external stressor bothering the child, are varied systematically. Although the results of both simulations differed considerably, they shared the fact that small changes in stressor intensity produced abrupt changes from one type of interaction to another. In addition, increasing stressor intensity sometimes had the paradoxical effect of resulting in less, rather than more, distress on the side of the child. Though irritability and responsiveness were varied in a less fine‐grained way than stressor intensity, the results suggest that similarly small differences in these dimensions at different parts of the dimension's scale range have differentially strong effects on the nature of the interaction. It is concluded that these simulations help us to specify the nature of empirically researchable phenomena that are to be expected, given the assumptions listed above. Further elaboration of the models and comparison with longitudinal empirical data is needed to answer further theoretical and practical questions. Copyright © 2000 John Wiley & Sons, Ltd. 相似文献

认知特征、场独立性与飞行空间定向关系的研究 总被引:13,自引:0,他引:13
通过认知分化测验(CLB)、团体镶嵌图形测验(GEFT)以及飞行定向水平的模糊评价技术,旨在检验认知特征、场独立性和飞行空间定向水平之间的关系。研究结果表明;(1)高水平的视觉空间认知能力及较强的场独立性特征不仅有助于获得一个良好的飞行定向水平,而且还构成了预测定向水平差异的有效指标;(2)场独立性特征与空间认知特征之间存在着一个很高的相关。具有较强场独立性特征的飞行员往往也具有较为典型的空间认知特征;(3)错觉水平较低的飞行员与中、重度错觉水平组飞行员在空间认知、认知分化和场独立性上的得分分别构成了显著的差异,表明轻度组飞行员在空间定向中表现出了良好的视觉空间信息组织、加工和某些元认知技能方面的优势。研究结果进一步证明了视觉空间认知加工和场独立性水平与飞行空间定向之间的紧密关系。 相似文献

The Dynamics of General Developmental Mechanisms: From Piaget and Vygotsky to Dynamic Systems Models
Paul van Geert 《Current directions in psychological science》2000,9(2):64-68
Dynamic systems theory conceives of development as a self-organizational process. Both complexity and order emerge as a product of elementary principles of interaction between components involved in the developmental process. This article presents a dynamic systems model based on a general dual developmental mechanism, adapted from Piaget and Vygotsky. The mechanism consists of a conservative force, further strengthening the already-consolidated level, and a progressive force, consolidating internal contents and procedures at more advanced levels. It is argued that this dual mechanism constitutes one of the few basic laws of learning and change, and is comparable to the laws of effect and of contiguity. Simulation studies suggest that this dual mechanism explains self-organization in developmental paths, including the emergence of discrete jumps from one equilibrium level to another, S-shaped growth, and the occurrence of co-existing levels. 相似文献
