This study examined the effects of parent-implemented mand training on the acquisition of framed manding in a 4-year-old boy who had undergone partial hemispherectomy. Framed manding became the predominant mand form when and only when the intervention was implemented with each preferred toy, but minimal generalization to untrained toys nevertheless occurred. A pure mand test suggested that manding was controlled by the relevant motivating operation. 相似文献

The current study examined the utility of multiple-exemplar training to teach children with autism to share. Stimuli from 3 of 4 categories were trained using a treatment package of video modeling, prompting, and reinforcement. Offers to share increased for all 3 children following the introduction of treatment, with evidence of skill maintenance. In addition, within-stimulus-category generalization of sharing was evident for all participants, although only 1 participant demonstrated across-category generalization of sharing. Offers to share occurred in a novel setting, with familiar and novel stimuli, and in the presence of novel adults and peers for all participants during posttreatment probes. 相似文献

Divergent thinking (DT) tests are among the most popular techniques for measuring creativity. However, the validity evidence for DT tests, as applied in educational settings, is inconsistent partly due to different scoring methods. This study explored the reliability and validity issues of various techniques for administering and scoring two DT tests. Results show distinct differences among several methods for scoring these DT tests and suggest that the percentage scoring method (i.e., dividing originality scores by fluency scores) may be the most appropriate scoring strategy. The potential impact on educational research and practice is discussed in detail. 相似文献

过度泛化现象是区分普通心理问题和严重心理问题的重要指标。创伤后应激障碍(posttraumatic stress disorder, PTSD)患者在创伤事件后会出现非适应性的泛化。现有研究结果表明非适应性泛化(maladaptive generalization)可能是PTSD发生发展的一个重要因素, 但也有研究支持PTSD是导致了泛化从适应性向非适应性化转变的原因。虽然泛化现象的变化与PTSD症状的发展有相同趋势, 且具有共同的生理基础:记忆相关神经结构, 但二者之间的关系尚无明确定论。阐明PTSD与非适应性泛化之间的关系对PTSD的预测、诊断和治疗均有推进作用。 相似文献

恐惧泛化是条件性恐惧反应转移到另一个相似但安全的刺激的现象。适当的恐惧泛化对人类有积极意义, 而过度的恐惧泛化则不利于个体有效地适应环境。基于知觉的恐惧泛化研究揭示了恐惧泛化的规律, 因而被广泛应用。本文首先梳理了对知觉恐惧泛化的相关研究, 介绍恐惧泛化的经典理论基础—巴普洛夫条件反射以及恐惧泛化梯度; 其次简要回顾基于多个感觉通道(即视觉、听觉、情景)的知觉恐惧泛化研究现状; 再次, 分别对海马、杏仁核、脑岛和前额叶等脑区在恐惧泛化中的作用进行回顾, 进一步总结出恐惧泛化的神经环路结构模型。最后, 简要区分了基于知觉的恐惧泛化和正在兴起的基于概念的恐惧泛化, 进而指出未来研究需要结合基于概念的恐惧泛化、区分被试对刺激的辨别力、增加恐惧刺激材料的准确性及多样化、结合激素等个体差异和多模态脑成像数据来展开。 相似文献

We consider the problems arising from using sequences of experiments to discover the causal structure among a set of variables,
none of whom are known ahead of time to be an “outcome”. In particular, we present various approaches to resolve conflicts
in the experimental results arising from sampling variability in the experiments. We provide a sufficient condition that allows
for pooling of data from experiments with different joint distributions over the variables. Satisfaction of the condition
allows for an independence test with greater sample size that may resolve some of the conflicts in the experimental results.
The pooling condition has its own problems, but should—due to its generality—be informative to techniques for meta-analysis. 相似文献

The purpose of this study was to further evaluate the outcomes of a model program that was designed to train current teachers of children with autism. Nine certified special education teachers participating in an intensive 5-day summer training program were taught a relatively large number of specific skills in two areas (preference assessment and direct teaching). The teachers met the mastery criteria for all of the skills during the summer training. Follow-up observations up to 6 months after training suggested that the skills generalized to their classrooms and were maintained for most teachers with brief feedback only. 相似文献

临床方法依然是神经内科医师最重要的诊断法宝 总被引:1,自引:1,他引:0
通过7例疑难、危重患者的诊治过程说明临床方法的重要性,在神经科疾病研究中尤为突出。忽视细致的病史采集和体查,常导致了诊疗的失误;面对种目繁多的检查,更需要以临床方法选择之;临床逻辑思维能力非常重要,正确的临床思维出新知。在实验室检查方法越来越多的今天,临床方法是神经内科医师最重要、方便、快捷、有效的诊断法宝,具有不可替代性。 相似文献

This study investigated how shallow processing (complexity rating), deep processing (pleasantness rating), and semantic generation (translating from English) of Chinese words affects conscious memory (CM) and unconscious memory (UM) of the words with three implicit tests: word association, word identification, and word-stem completion. A metacognition-based dissociation procedure was used to estimate the two forms of memory for each test. Except for the shallow condition preceding the word-association test, all three study conditions produced a positive effect on the estimate of CM. The estimate of UM did not benefit from any of the study conditions in the word-association test, it benefited from the shallow and deep conditions but did not benefit from the generation condition in the stem-completion test, and it benefited from the shallow condition but did not benefit from the deep and generation conditions in the word-identification test. Implications of these results for CM and UM operations are discussed. 相似文献

本研究介绍并引进了现代测量理论中的前沿技术—— 多维项目反应理论, 采用MCMC算法实现了其参数估计; 并将MIRT应用于瑞文高级推理测验, 以探讨MIRT在心理测验中的具体应用。研究结果表明:(1)本研究自主编制的MIRT参数估计程序基本可行, 其估计的精度与国外研究结论相当甚至更好。(2)在测验维度和样本容量两因素完全随机实验设计下(2×3), 随着被试和题目样本容量的增加, MIRT参数估计的精度越高且估计的稳定性越强; 但随着测验维度的增加, MIRT参数估计精度和稳定性均随之降低。(3)MIRT对心理测验的分析比UIRT能提供更为精确和细致的信息。它对心理测验的编制、开发及评价具有重要的指导和参考价值, 值得引进及借鉴。 相似文献
