Treatment for Youth in Short-Term Care Facilities: The Impact of a Comprehensive Behavior Management Intervention

We describe a comprehensive program to train emergency shelter staff in effective methods for dealing with youth who have behavioral and emotional problems; assess the degree to which staff implemented the treatment approach; measure the impact of the intervention on shelter-wide incidents such as out-of-control behavior, runaways, and violence against other youth; and examine pre-post changes in staff experiences at the shelter via anonymous surveys. Overall, the short-term shelter staff indicated adequate implementation of the intervention. The rate of youth incidents at the shelter significantly declined from pre to post assessment. Direct-care staff ratings of their satisfaction with their proficiency in behavior management and teaching youth skills increased significantly from pre to post implementation. These findings suggest that it is feasible to deliver an effective staff-training program to improve the behavior management and social skills of youth residing in short-term care facilities within the child welfare system.     

词汇的语义表征及其启动效应研究现状与问题

语义启动是研究语义表征的主要范式。在过去的30年里,通过对语义启动效应的研究,词汇的语义表征理论也从符号联结发展到神经联结,其影响因素也逐步重视多方面的交互作用。究其问题,已有研究还存在很多不一致的结论,对语义内在的表征机制和学习机制缺乏深入了解,对影响语义表征的个体因素考虑不多。     

儿童整体-局部加工中的负启动现象

采用2种元素疏密程度的复合数字刺激和启动范式,7岁和11岁2个年龄组的小学生分别在注意整体水平和注意局部水平的条件下对探测刺激进行选择反应。结果发现元素疏密程度可以影响知觉优先,而知觉优先与整体局部水平间的负启动之间没有一致的发展关系,说明与负启动有关的注意分配机制可能比知觉组织发展的晚。     

情绪启动研究的实验范式

情绪启动是探讨情绪和态度自动激活的有效方法,近期其研究范式有了较大的发展,相继产生了经典情绪启动实验、阈下情绪启动实验、向后情绪启动实验以及情绪启动与其他范式相结合的实验等较有影响的研究范式。文章分别梳理了这些范式及其研究结果,并在此基础上,总结研究所采用的范式并展望今后研究的发展趋势。     

类皮亚杰数量守恒任务中的负启动效应

采用负启动研究范式,考察九岁儿童在类皮亚杰数量守恒任务中的负启动效应。实验一重复了Houdé等人的实验过程,发现我国儿童在解决类皮亚杰数量守恒任务中也存在负启动效应,负启动量为310.9ms;实验二改进了Houdé等人研究的实验材料,排除实验材料形状的干扰,发现依然存在负启动效应,负启动量为200.04ms。实验结果表明,成功完成类皮亚杰数量守恒任务需要认知抑制过程的参与。     

双语跨语言的句法启动

本文介绍了跨语言句法启动的图片描述法、补句法和句子回忆法三种研究方法;总结了跨语言句法启动研究关注的主要问题,包括：词序的一致性对跨语言句法启动的影响、词汇因素在跨语言句法启动中的作用、语言内和语言间句法启动的比较以及跨语言句法启动产生的机制等。同时也指出,在双语词序一致性,第二语言的熟练程度,双语语言学特性的差异性是否或者如何影响跨语言的句法启动等方面仍需进一步的研究     

保留的跨通道启动与老化：对于近期观点的总结

通道内重复启动的研究提示老年人内隐记忆未受损, 这不只体现在视觉通道上还包括其他感觉通道(例如触觉、听觉和嗅觉)。然而很少有研究考察启动任务是否具有通道特异性。在以年轻人为被试的研究中发现跨通道迁移(视觉到触觉和触觉到视觉)和通道内迁移(视觉到视觉, 触觉到触觉)具有相似性。一项最近的研究进一步探索老年人在跨通道启动任务上是否受损。结果显示视觉和触觉间的跨通道启动在年轻被试和老年被试上都是保留的且具有对称性。并且, 对于自然声响、图片的通道内和跨通道启动任务随着年老化发展仍旧保留。这些行为结果和其它最近神经科学结果显示跨通道启动发生于枕叶后纹状皮层区, 而这一区域在老年人中未损坏。这一领域未来的研究方向包括利用不同知觉通道间、利用熟悉的和新异的刺激并结合行为的和脑成像的方法, 通过设计完善的跨通道启动来研究正常老人与阿尔兹海默病人, 还包括将设计得完善的启动任务包括在用于改善老年人记忆功能的项目中。     

A new dynamical model of brainstorming: Linear, nonlinear, continuous (simultaneous) and impulsive (sequential) cases

In this paper, we extended the linear dynamical model of [Brown, V., Paulus, P. B. (1996). A simple dynamic model of social factors in group brainstorming. Small Group Research, 27, 91-114] on two accounts. First, we modelled the sequential type brainstorming using impulsive differential equations by treating each category as an impulse and tested its validity in the two experiments that investigated and demonstrated the beneficial effects of sequential priming and memory in individual brainstorming. Finally, we considered the nonlinear case of brainstorming in writing or brainwriting where dyads exchanged their ideas in a written format and that eliminated negative factors occurring in oral brainstorming (e.g., evaluation apprehension, free-riding, production blocking) and enhanced the upward performance matching, and conducted the second experiment in order to test its validity in this paradigm with the effects of sequential priming and memory. Comparisons showed good agreement between results of experiments and those of the mathematical model.     

The Time Course of Verb Processing in Dutch Sentences

The verb has traditionally been characterized as the central element in a sentence. Nevertheless, the exact role of the verb during the actual ongoing comprehension of a sentence as it unfolds in time remains largely unknown. This paper reports the results of two Cross-Modal Lexical Priming (CMLP) experiments detailing the pattern of verb priming during on-line processing of Dutch sentences. Results are contrasted with data from a third CMLP experiment on priming of nouns in similar sentences. It is demonstrated that the meaning of a matrix verb remains active throughout the entire matrix clause, while this is not the case for the meaning of a subject head noun. Activation of the meaning of the verb only dissipates upon encountering a clear signal as to the start of a new clause.     

熟练维-汉双语者第二语言的概念表征的特征

以母语为维吾尔语,第二语言为汉语的的维吾尔族大学生为被试,使用语言内和语言间启动条件下的真假字判断任务,通过3个实验探讨了熟练的维汉双语者的第二语言的语义表征的特点,即他们的第二语言的语义表征是共同存储的还是独立存储的。结果发现,实验1语言内启动条件下,即启动刺激（维语）和目标刺激（维语）之间具有语义联想关系时,产生了显著的启动效应。实验2（启动刺激为维语,目标刺激为汉语）和实验3（启动刺激为汉语,目标刺激为维语）的跨语言启动条件下,都产生了显著的启动效应,说明被试的第二语言的语义表征是共同存储的。这些结果表明：被试的第二语言的概念表征是同第一语言的概念表征共同存储的,支持了共同存储理论。
