初中生家庭社会经济地位、积极品质对中考成绩的预测作用

以442名初中生为被试,采用历时20个月的纵向研究考察家庭社会经济地位（socioeconomic status, SES）和积极品质对中考成绩的预测作用。结果发现：（1）家庭SES、积极品质整体发展水平可以同时显著正向预测初中生在20个月后的中考成绩;（2）积极品质整体发展水平在家庭SES与中考成绩之间存在中介作用,即家庭SES越高,初中生的积极品质整体水平越高,其中考成绩越好。研究结果提示积极品质可以补偿低家庭SES对学生中考成绩的不良影响。     

支持型领导行为在工作压力模型中的作用机制研究

本研究调查了 1 3个企业共 2 1 8位员工 ,探讨了支持型领导行为在角色冲突、人际冲突、缺乏成就与发展 (压力源 )和工作满意感、工作焦虑 (压力反应 )之间的作用机制。研究发现 :(1 )支持型领导行为对工作满意感和工作焦虑有主效应 ,但是由于逆向缓冲的存在 ,支持型领导行为的主效应并不总是对的 ,我们必须在更大的范围中考虑领导行为的效应 ;(2 )缓冲效应的六个假设只有一个被证明 ,但是方向相反 ,即支持型领导行为加剧了由人际冲突造成的工作不满意感 ;(3)两个中介模型的部分关系被证明 ,但是我们很难确定是支持型领导行为的弱化效应还是评价作用。为了更好地说明因果关系 ,在将来的研究中纵向研究设计被认为更为恰当。     

听觉线索与个体差异对音乐紧张感加工的影响

音乐无他, 张弛而已。音乐紧张感架起了客观音响与主观体验之间的桥梁, 是音乐情绪产生的前提和基础。音乐紧张感加工的影响因素主要来自客体与主体两方面。研究发现, 声学要素与调性结构是影响音乐紧张感诱发的声音线索, 而文化背景与音乐能力是影响听者对紧张感加工的个体因素。未来需要对时间结构与长时程调性结构诱发的紧张感及其机制进行深入探究, 这将有助于深化我们对音乐紧张感与情绪加工的认识。     

Resolution of dilemmas: A mathematical theory

A mathematical formulation for a dilemma (i.e. a situation in which a very difficult choice between two alternatives must be made) is given. Multiple-objective programming is assumed as the model for a single decision maker. It is shown that, in principle, any dilemma is resolvable. Furthermore, there is always more than one way in which to resolve a dilemma. Illustrative examples from non-convex optimization are presented.     

Regression II. Development through regression

As shown in our previous paper (‘Regression I. Experimental approaches to regression’, JAP, 65, 2, 345-65), the common mechanism of regression can be described as reversible dedifferentiation, which is understood as a relative increase of the proportion of low-differentiated (older) systems in actualized experience. Experimental data show that regression following disease (chronic tension headache) is followed by adaptation and an increase in system differentiation in that experience domain which contains systems responsible for that adaptation. The results of mathematical modelling support the idea that reversible dedifferentiation can be one of the mechanisms for increasing the effectiveness of adaptation through learning. Reversible dedifferentiation, which is phenomenologically described as regression, is a general mechanism for restructuring the organism-environment interactions in situations where behaviours that were effective in the past become ineffective. Reversible dedifferentiation has evolved as a component of adaptation when new behaviours are formed and large-scale modifications in the existing behaviours are required in the face of changes in the external and/or internal environment. Thus, the authors believe that this article provides evidence for Jung’s view that regression is not only a ‘return’ to past forms of thinking, affects and behaviour, but that regressive processes provide a significant impetus for psychological growth and development.     

Age-Specific Effects of Lexical–Semantic Networks on Word Production

The lexical–semantic organization of the mental lexicon is bound to change across the lifespan. Nevertheless, the effects of lexical–semantic factors on word processing are usually based on studies enrolling young adult cohorts. The current study aims to investigate to what extent age-specific semantic organization predicts performance in referential word production over the lifespan, from school-age children to older adults. In Study 1, we conducted a free semantic association task with participants from six age-groups (ranging from 10 to 80 years old) to compute measures that capture age-specific properties of the mental lexicon across the lifespan. These measures relate to lifespan changes in the Available Richness of the mental lexicon and in the lexical–semantic Network Prototypicality of concrete words. In Study 2, we used the collected data to predict performance in a picture-naming task on a new group of participants within the same age-groups as for Study 1. The results show that age-specific semantic Available Richness and Network Prototypicality affect word production speed while the semantic variables collected only in young adults do not. A richer and more prototypical semantic network across subjects from a given age-group is associated with faster word production speed. The current results indicate that age-specific semantic organization is crucial to predict lexical–semantic behaviors across the lifespan. Similarly, these results also provide cues to the understanding of the lexical–semantic properties of the mental lexicon and to lexical selection in referential tasks.     

Age influences domestic dog cognitive performance independent of average breed lifespan

Animal Cognition - Across mammals, increased body size is positively associated with lifespan. However, within species, this relationship is inverted. This is well illustrated in dogs (Canis...     

工作反刍及其“双刃剑”效应

工作反刍指在没有要求其出现的情境下, 有意识的、重复发生的工作方面的相关想法, 分为工作相关情感反刍与工作相关问题解决沉思两个维度。工作反刍对个体健康、工作及幸福感的影响有“双刃剑”效应。持续性认知理论、压力认知激活模型与认知资源视角理论, 可以解释该效应的内在机制。未来研究应分析影响双刃剑效应的边界条件, 寻求减少消极效应、增加积极效应的途径, 拓展其双刃剑效应心理机制的分析视角和该效应的作用层面。
