佛教对当代心理学发展的影响

佛教是一种重要的东方哲学文化,它的一些精神已经渗透进了当代的许多学科领域。在心理学领域,心理学在思想层面、理论层面和实践层面都能看到佛教的核心精神——Dukkha箴言(人的苦难)、Tanha箴言(人的欲望)、Nirvana箴言(苦难中的涅槃)和Magga箴言(摆脱苦难的路径)的影子。因此,探求佛教文化在当代心理学中的生存状况,寻找心理学视野下的真实佛教就成为当代心理学研究的一个基础性问题。     

Computer‐based teaching of word construction and reading in two students with developmental disabilities

Students with developmental disabilities often have difficulty in learning the systematic relations between syllables (auditory stimuli) and characters (visual stimuli) required for reading. Two students with developmental disabilities participated in the present study which used computer‐based teaching applied in the home. We examined whether the students could read individual Japanese Hiragana characters after training with a constructional MTS procedure with differential outcome (DO) that was designed to teach word‐construction for pictured sample stimuli. The DO procedure provided the differential stimulus (in this case spoken syllables) after response selection. The results showed that the students not only acquired appropriate word‐construction responses through this task, they also learned to read Hiragana characters without direct training of this skill. The results are discussed in terms of the effect of the constructional MTS procedure with DO on the acquisition and transfer of reading characters and the applicability of computer‐based home teaching.

Assessing the multidimensional and hierarchical structure of SERVQUAL

Parasuraman, Zeithaml, and Berry introduced SERVQUAL in 1998 as a scale to measure service quality. Since then, researchers have proposed several variations. This study examines the development of the tool. Marketing researchers have first challenged the conceptualization of a perceptions-expectations gap and have concluded that the performance-based measures are adequate to capture consumers' perception of service quality. Some researchers have argued that the five dimensions of the SERVQUAL scale only focus on the process of service delivery and have extended the SERVQUAL scale into six dimensions by including the service outcome dimension. Others have proposed that service quality is a multilevel construct and should be measured accordingly. From a sample of 467 undergraduate students data on service quality toward up-scale restaurants were collected. Using the structural equation approach, two measurement models of service quality were compared, the extended SERVQUAL model and the restructured multilevel SERVQUAL model. Analysis suggested that the latter model fits the data better than the extended one.     

Feature binding in visual working memory evaluated by type identification paradigm

Memory for feature binding comprises a key ingredient in coherent object representations. Previous studies have been equivocal about human capacity for objects in the visual working memory. To evaluate memory for feature binding, a type identification paradigm was devised and used with a multiple-object permanence tracking task. Using objects defined by shape and color, observers identified types of changes in feature combinations across an occlusion event, and the effects of object motion and number of switches were investigated. With only one switch, task performance was impaired even under stationary conditions, suggesting highly limited capacity of binding memory. Second switch improved performance only in the stationary condition, suggesting that object motion strongly disrupts feature binding. Further analyses and experiments suggest that improvement by the second switch reflects transition of binding memory by selective attention.     

青少年攻击性问卷的编制

在青少年攻击性理论与当代青少年攻击性表现的基础上,结合国外的研究成果以及专家评定,通过探索性因素分析和验证性因素分析,编制了一个适合青少年攻击性评估的问卷。结果发现：（1）自编的“青少年攻击性问卷”由攻击性行为、攻击性认知和攻击性情绪3个分量表构成。攻击性行为分量表由口头攻击、身体攻击、自我发泄3个维度构成;攻击性认知分量表由敌对、恶意、报复心理3个维度构成;攻击性情绪分量表由易怒性、冲动、缺乏自我控制能力3个维度构成;（2）问卷的内部一致性系数和维度与分量表、总分以及分量表与总分的相关系数达到显著水平,量表的内容效度、结构效度、实证效度较高。     

视觉工作记忆在视觉搜索中的作用

视觉工作记忆在视觉搜索中的作用远比偏向竞争模型所描述的要复杂,个体能根据当前任务要求灵活地利用工作记忆来引导注意选择。在系统回顾已有研究的基础上,从客体工作记忆、空间工作记忆和执行工作记忆3个方面探讨了视觉工作记忆在视觉搜索中的作用。根据近期的研究,文章在最后对视觉工作记忆在视觉搜索中的作用做了7点总结,并对已往研究中存在的若干问题给予了解释,指出未来应该从前瞻记忆和内隐记忆等角度对视觉搜索中所涉及的视觉记忆进行深入研究     

空间行为关系类比匹配中客体相似性的作用

客体相似性在类比匹配中的作用,是一直存在着争论的问题。该研究通过交叉匹配结合与分离的材料设计,控制类比源和类比目标之间不同相似性,探讨了客体相似性在儿童和成人空间行为关系类比匹配中的作用。实验一通过让儿童和成人完成单目标匹配任务,检验客体相似性对儿童和成人类比匹配影响的不同。实验二采用眼动技术对客体相似性在成人类比匹配过程中的作用进行分区域探讨。结果发现,客体相似性影响儿童空间行为关系类比匹配的成绩,但不影响成人的成绩。成人类比匹配的过程受到结合在关系结构之内的客体相似性的影响。我们提出优先-限制调整观点解释客体相似性在类比匹配中的作用。     

音乐的速度与调式对大学生情绪影响的实证研究

以92名大学本科生为实验对象,用剪辑的8首乐曲片断为实验材料,考察其调式和速度对大学生情绪的影响。结果表明:乐曲片断的速度对大学生的情绪影响非常显著,但调式的主效应不显著;慢速的乐曲易于诱发大学生忧伤、悲哀、痛苦、烦躁和愤恨等负性情绪;快速的乐曲大多数导致大学生愉悦与兴奋等正性情绪。乐曲的速度与调式对大学生情绪影响的差异十分显著。速度在调式上两水平的差异显著,尤其是在大调上差异非常显著。但调式只有在慢速水平上差异十分显著,而在快速水平上差异不显著。     

Fos expression in CRF-containing neurons in the rat paraventricular nucleus after central administration of neuromedin U

We examined the effects of centrally administered neuromedin U (NMU) on corticotrophin-releasing factor (CRF)-containing neurons in the hypothalamic paraventricular nucleus (PVN) of rats, using double immunohistochemistry for CRF and Fos. Almost all CRF-containing neurons in the parvocellular divisions of the PVN expressed Fos-like immunoreactivity 90 min after intracerebroventricular administration of NMU (3 nmol/rat). This results suggest the possibility that central NMU may be involved in stress-induced activation of CRF-containing neurons in the PVN.
