Children's early productivity with verbal morphology

Three studies using the intermodal preferential looking paradigm examined onset of productive comprehension of tense/aspect morphology in English. When can toddlers understand these forms with novel verbs and novel events? The first study used familiar verbs and showed that 26–36-month olds correctly matched a past/perfective form (-ed or irregular past) to a completed version of an event and a present/imperfective (is V-ing) to the ongoing version of the same event. The second study used novel verbs and events and found that 33-month olds failed to use tense/aspect morphology to choose between completed and ongoing versions of the same event. The third study also used novel verbs and events but simplified the processing demands of the task in several ways (using initial priming of the events and classes of meaning, using different events within test pairs). This study found that 30-month olds successfully used tense/aspect morphology to choose between ongoing and completed novel events. The results demonstrate that children have productive command of tense/aspect morphology by 30 months and have therefore begun the process of creating an abstract grammar containing this element.     

Children's understanding of communicative intentions in the middle of the second year of life

Two tasks were administered to 40 children aged from 16 to 20 months (mean age = 18;1), to evaluate children's understanding of declarative and informative intention [Behne, T., Carpenter, M., & Tomasello, M. (2005). One-year-olds comprehend the communicative intentions behind gestures in a hiding game. Developmental Science, 8, 492–499; Camaioni, L., Perucchini, P., Bellagamba, F., & Colonnesi, C. (2004). The role of declarative pointing in developing a theory of mind. Infancy, 5, 291–308]. In the first task, children had to respond to the experimenter who pointed at a distal object; in the second task, children had to find a toy in a hiding game after the experimenter indicated the correct location either by pointing or by gazing. In the first task, most children responded to the declarative gesture by “commenting” on the pointed object instead of just looking; however, looking responses were more frequent than commenting responses. In the second task, children chose the correct location of the object significantly more frequently when the informative gesture was the point than when it was the gaze; moreover, there were significantly more correct choices than incorrect choices in the point but not in the gaze condition. Finally, no significant relation was found between tasks. Taken together, the findings support the view that infants’ developing understanding of communicative intention is a complex process in which general cognitive abilities and contextual factors are equally important.     

Metacognitive Judgments and Control of Study

ABSTRACT— Recent evidence indicates that people's judgments of their own learning are causally related to their study behavior and not epiphenomenal. I argue here that people use these metacognitions in an effort to selectively study material in their own region of proximal learning. First they attempt to eliminate materials that are already well learned. Then they progress successively from studying easier to more difficult materials. Successful implementation of this metacognitively guided strategy enhances learning. The necessary components are, first, that the metacognitions be accurate, and second, that the appropriate choices are implemented for study. With these parts in place, the individual is in position to effectively take control of his or her own learning.     

夫妻沟通模式与婚姻质量的关系

本文拟采用主-客体互倚模型(Actor-partner interdependence model,APIM)的方法深入探讨夫妻双方感知到的夫妻间的沟通模式与其自身及配偶感知到的婚姻质量之间的关系。以方便取样的方式在澳门地区选取130对成年夫妻,采用Christensen等人修订的沟通模式调查问卷(Communication Pattern Questionnaire,CPQ)和Spanier编制的婚姻质量问卷(Dyadic Adjustment Scales,DAS),要求夫妻双方分别以自陈问卷的方式报告其感知到的沟通模式和婚姻质量。通过配对t检验、相关分析和结构方程模型统计分析发现:(1)夫妻间的沟通以建设性沟通为主,双方回避和要求/回避型沟通较少;丈夫感知到的婚姻质量总体上优于妻子感知到的婚姻质量。(2)夫妻双方在沟通模式和婚姻质量的感知上具有一致性,在沟通模式中的两个和婚姻质量中的三个分量表上的得分不存在显著差异。(3)夫妻间建设性沟通可以显著地正向预测自身感知到的婚姻质量;而双方回避和要求/回避型沟通则显著地负向预测自身感知到的婚姻质量。(4)在控制了丈夫、妻子感知到的沟通模式对其自身婚姻质量的主体效应之后,丈夫感知到的沟通模式可以显著地预测妻子感受到的婚姻质量;然而妻子感知到的沟通模式并不能显著地预测丈夫的婚姻质量。     

责任心的多元内涵与结构及其理论整合

责任心研究, 在心理学不同领域有类似的对象、相近的内涵, 但又有不同的概念界定、研究方法和测量工具, 研究结果迥异。文章首先回顾了已有研究对责任心内涵和结构的探索, 试图从整体上把握责任心研究在各领域成果间的关联;其次, 对人格领域、道德领域和认知领域中与责任心相关的的理论进行了分析;最后, 基于对责任三角模型优势和局限的分析, 并结合先前理论的启示, 尝试提出了一个更具综合性的责任心三侧面理论模型, 并探讨了该模型在理论上可能具有的特征。     

骨盆测量在直肠癌手术中的应用进展

回顾当前各种骨盆测量手段,分析骨盆径线与直肠癌手术难度的关系。CT和MRI是目前直肠癌骨盆测量的较好选择,坐骨棘间径、坐骨结节间径、上耻骶尾骨最短径、骶尾骨长度和骶尾骨弯曲度等径线对直肠癌手术难度的影响已经得到了证实。未来的研究需要建立骨盆测量评价标准以指导临床医师制定手术方案。     

注意缺陷多动障碍的研究与治疗

注意缺陷多动障碍（ADHD）的发病群体多为5岁以后的儿童,主要临床表现是多动、冲动,注意力无法集中,对一项任务不能够有规划进行下去,而且脾气暴躁、易怒。近年来,心理学界、神经科学界和教育学界等对ADHD的研究取得了很多进展。本文概括性地介绍了ADHD病症的基本特征,目前对于患者脑机制损害的研究,并从药理学和行为学等方面讨论了ADHD的治疗方法和手段。

Person-organization fit: Testing socialization and attraction-selection-attrition hypotheses

Using the socialization and attraction-selection-attrition (ASA) frameworks, this study examined the relation between employees’ work values and their organization’s values (person-organization fit). With a two year time interval, 140 respondents participated in a longitudinal study. After entry, socialization served to enhance homogeneity. The work values underwent small changes and the perception of fit with the organization grew. Despite high retention rates results confirmed the attrition effect. Results indicated that the lower the perceived match between own and organizational values at entry, the more likely it was that someone left the organization over time. We concluded that socialization as well as attrition mechanisms were present at the same time.     

The Signal-Cognition interface: Interactions between degraded auditory signals and cognitive processes

A hearing loss leads to problems with speech perception; this is exacerbated when competing noise is present. The speech signal is recognized by the cognitive system of the listener; noise and distortion tax the cognitive system when interpreting it. The auditory system must interact with the cognitive system for optimal signal decoding. This article discusses this interaction between the signal and cognitive system based on two models: an auditory model describing signal transmission and degeneration due to a hearing loss and a cognitive model for Ease of Language Understanding. The signal distortion depends on the specifics of the hearing impairment and thus differently distorted signals can affect the cognitive system in different ways. Consequently, the severity of a hearing loss may not only depend on the lesion itself but also on the cognitive recourses required to interpret the signal.
