极地环境中的心理学研究

极端特殊的孤立与封闭环境向深入南极大陆的科考人员提出了极其严峻的挑战,同时也为心理学研究提供了一个天然实验室。对于南极科考人员而言,多数人越冬期间会在不同程度上经历和承受“越冬综合症”和“四分之三现象”,他们的积极心理经历和体验已经开始受到关注。文章重点介绍了有关南极科考人员可能出现的症状、适应特征、科考人员的人格特征以及站区文化对行为的影响等方面的研究结果,对现有研究存在的问题进行了初步探讨,提出了未来研究将会开展更广泛的国际化合作、聚焦环境、人格和行为三者的关系以及积极心理学在特殊环境中的重要作用等主题     

不同加工任务下情绪词的掩蔽重复启动效应

重复可促进信息的加工,人们对一定时间范围内重复出现的刺激能够更快更准的做出反应.本研究采用掩蔽重复启动范式,考察了情绪与非情绪判断任务中积极与消极词的阈下重复所产生的启动效应.结果发现.情绪判断任务下积极词反应优于消极词,并且表现出更大的重复启动效应;而具体抽象判断任务中,非重复启动条件下积极词反应仍优于消极词,但消极词重复产生了更大的启动作用,在启动条件下其反应优于积极词.     

熟悉性:基于知觉还是语义流畅性加工

该文运用任务分离法和Remember/Know程序,分别以图形和汉词为材料,研究集中注意和重度分散注意条件下内隐记忆和熟悉性的关系,以揭示外显记忆中熟悉性的属性,结果发现:(1)知觉性内隐记忆在集巾注意和蕈度分散注意下差异不显著,再认中的熟悉性在这两种注意水平下差异显著;(2)概念性内隐记忆、线索回忆中的熟悉性在两种注意水平下差异均显著.据此熟悉性和知觉性内隐记忆相分离,与概念性内隐记忆未出现分离,从而可以推测外显记忆中的熟悉性主要受语义流畅性加工调节.     

人类超常记忆的认知神经科学研究综述

借助脑成像技术,人类超常记忆研究揭示出:世界记忆大师与常人存在显著的脑功能差异,如海马等区域的激活;随着领域内训练增加,知识与经验逐渐取代一般能力来影响记忆活动,如在空间记忆任务上相关脑区激活量减少且集中;行为层面的记忆理论找到了相应的电生理基础,如国际象棋记忆的"组块"位于颞叶,音乐领域的"长时工作记忆"与脑区负波有关.同时,期待更多从生理层面上来揭示人类超常记忆能力实质的研究.     

先秦儒家美学之"美"的边界

“Beauty” is a very important concept in Pre-Qin Confucian aesthetics. Pre-Qin Confucian aesthetics generally had two viewpoints when defining beauty: Negatively, by stressing that “beauty” in the aesthetic sense was not “good”; and positively, by stressing two factors: one, that beauty was related to “feeling” which was not an animal instinct, the other was that “beauty” was a special texture with a particular meaning. “Beauty” in Pre-Qin Confucian aesthetics may be defined as “texture (or form)” capable of communicating feeling or triggering a reaction of feeling. __________ Translated from Shanghai shifan daxue xuebao 上海师范大学学报 (Journal of Shanghai Normal University), 2007, (7): 80–85     

二孩家庭中的同胞嫉妒及其影响因素

随着多孩政策的开放,同胞嫉妒易发且普遍存在。同胞嫉妒指家庭中一个孩子与父母的亲密关系受到另一个孩子威胁或挑战时出现的认知、情绪和行为的复合体。本文深入挖掘同胞嫉妒的内涵、价值及其个体、养育者和社会文化等维度的影响因素,未来研究需要进一步注重综合作用机制研究;重视干预性研究,探索缓解同胞嫉妒的方法。     

第一印象中面孔-人格知觉和语音-人格知觉的异同

人们会根据陌生人的面孔线索或语音线索迅速地对其人格特质进行主观推断而形成第一印象。面孔-人格知觉第一印象和语音-人格知觉第一印象在维度结构和内在机制上具有相似性;在对具体人格特质和维度的敏感性,以及具体的认知机制方面又具有各自的特异性。未来研究可以基于同一批被知觉者开展面孔-人格知觉第一印象和语音-人格知觉第一印象的直接比较,并着力探究二者的过程特点,以及人格知觉第一印象形成时面孔和语音知觉的跨模态整合效应。     

中国近现代学习心理学发展轨迹之初探

中国近现代,自公元1900年到公元1949年,这一阶段中国学习心理学发展的轨迹可归纳为三个方面,理论研究：从翻译到评价再到独立探讨;实证研究：从实验法的倡导到大量实验研究的出现,实践研究：从近代学校的建立到大量有实践价值的学习观的提出。     

Cocaine-induced brainstem seizures and behavior

A variety of abnormal sensory/motor behaviors associated with electrical discharges recorded from the bilateral brainstem were induced in adult WKY rats by mechanical (electrode implants) and DC electrical current stimulations and by acute and chronic administration of cocaine. The electrode implant implicated one side or the other of the reticular system of the brainstem but subjects were not incapacitated by the stimulations. Cocaine (40 mg/kg) was injected subcutaneously for an acute experiment and subsequent 20 mg/kg doses twice daily for 3 days in a chronic study. Cocaine generated more abnormal behaviors in the brainstem perturbation group, especially the electrically perturbated subjects. The abnormal behaviors were yawning, retrocollis, hyperactivity, hypersensitivity, “beating drum” behavior, squealing, head bobbing, circling, sniffing, abnormal posturing, and facial twitching. Shifts in the power frequency spectra of the discharge patterns were noted between quiet and pacing behavioral states. Hypersensitivity to various auditory, tactile, and visual stimulation was present and shifts in the brainstem ambient power spectral frequency occurred in response to tactile stimulation. These findings suggest that the brainstem generates and propagates pathological discharges that can be elicited by mechanical and DC electrical perturbation. Cocaine was found to activate the discharge system and thus induce abnormal behaviors that are generated at the discharge site and at distant sites to which the discharge propagates. Cognitive functions may also be involved since dopaminergic and serotonergic cellular elements at the brainstem level are also implicated.     

Relationships among anxious symptomatology, anxiety sensitivity and laboratory pain responsivity in children

Existing laboratory-based research in adult samples has suggested that anxiety sensitivity (AS) increases an individual's propensity to experience pain-related anxiety, which in turn enhances pain responsivity. Such relationships have not been examined in younger populations. Thus, the present study used structural equation modeling (SEM) to test a conceptual model in which AS would evidence an indirect relationship with pain intensity via its contribution to state-specific anticipatory anxiety in relation to a variety of laboratory pain tasks (cold pressor, thermal heat, and pressure pain) in 234 healthy children (116 girls; mean age = 12.6 years, range = 8-18 years). The model further hypothesized that existing anxious symptomatology would demonstrate a direct relationship with pain intensity. Results of the SEM supported the proposed conceptual model with the total indirect effect of AS accounting for 29% of the variance in laboratory pain intensity via its effects on pain-related anticipatory anxiety. AS did not however, evidence a direct relationship with pain intensity. Anxious symptomatology on the other hand, demonstrated a significant direct effect on pain intensity, accounting for 15% of variance. The combined effects of AS, anxiety symptoms, and anticipatory anxiety together explained 62% of the variance in pain intensity. These relationships did not differ for boys and girls, indicating no moderating effect of sex in the proposed model. The present results support the potential benefit of assessing both AS and anxiety symptoms in children prior to undergoing painful stimulation.
