工作压力的研究现状与方向

工作压力的研究在西方已经进行了多年,并受到越来越多的注意,但在我国研究还较少。本文从工作压力的定义、对于工作压力的测量、影响工作压力产生的因素、工作压力的后果、以及应对这几个方面介绍这一领域目前的研究现状并提出作者认为这一领域现存的问题和今后的研究方向。     

婴儿物理因果感知能力的发展

继Michotte(1963)用两个发生碰撞的小球对成人的物理因果理解进行研究以来,许多研究者使用该碰撞情境对婴儿的物理因果感知进行了一系列的研究,并得出了许多颇有争议的结论。本文结合近几年国外对婴儿物理因果感知能力的相关研究,阐述了婴儿感知简单物理情境中的因果关系能力的发展,评价了用来解释婴儿物理因果感知的模块理论与信息加工理论,以期对婴儿期的物理因果感知有一较全面的了解。     

学习不良儿童的心理行为问题

学习不良儿童的心理行为问题已成为人们关注的一个焦点。从心理健康的角度考察,学习不良儿童心理行为问题主要表现在生活和社会适应、学习和违纪,以及焦虑、抑郁和自杀等方面;造成上述现象的主要原因要有自我概念较低、家庭因素的不良影响,以及社会认知方面存在的缺陷。可以通过干预和矫正学习不良儿童的心理行为问题,从而提高他们的心理健康水平。     

The Role of Autonomy Support and Autonomy Orientation in Prosocial Behavior Engagement

Two studies examined individual and environmental forces that affect engagement in prosocial behavior. Self-determination theory was used to derive a model in which autonomy orientation and autonomy support predicted satisfaction of three core psychological needs, which in turn led to engagement in prosocial activities. In Study 1, college students reported their engagement in various prosocial activities, and completed measures of autonomy orientation, parental autonomy support, and general need satisfaction. In Study 2, volunteer workers completed measures of autonomy orientation, work autonomy support and need satisfaction at work. The number of volunteered hours indicated the amount of prosocial engagement. Results across the studies showed that autonomy orientation was strongly related to engagement in prosocial behavior, while autonomy support was modestly related. Need satisfaction partially mediated the effect of autonomy orientation, and fully mediated the effect of autonomy support. Interestingly, autonomy support predicted lower volunteer turnover. Implications for how prosocial behavior can be motivated are discussed.     

The Undecidability of Grisin's Set Theory

We investigate a contractionless naive set theory, due to Grisin [11]. We prove that the theory is undecidable.     

Staff survey results and characteristics that predict assault and injury to personnel working in mental health facilities

The purpose of this study was to complete a mental health staff opinion survey to identify patient and staff characteristics associated with staff assault and injury in psychiatric treatment settings and to develop a model of prediction for staff assault and injury utilizing these survey variables. The data consisted of opinion surveys sent to staff of 15 child, adolescent, and adult psychiatry inpatient units in the United States. Multivariate logistic regression was used to determine the level of assault and staff‐reported injury prediction that could be obtained from the staff‐completed opinion survey. Responses indicated a high prevalence of reported aggression, with 62.3% of staff endorsing verbal and physical aggression, property destruction, and self‐injurious behavior as being prevalent at their site, whereas only 4.1% rated none of these as prevalent. Staff working with children and adolescents in settings with high rates of psychiatric diagnoses reported increased frequency of assault and injury compared with those working with adults. Younger, less experienced staff reported higher rates of assault and injury. Staff working with female patients reported similar rates of assault and injury to those working with males. A logistic regression analysis using staff‐reported survey results of both staff and patient characteristics predicted assault correctly 73.7% of the time and injury 66.1% of the time. Resources for violence prevention and staff training programs in violence prevention are needed in child and adolescent psychiatry wards. Results are consistent with theories emphasizing the importance of negative emotions and affects, impulsivity, and frustration in goal‐directed activities in human aggression. Aggr.

The anatomy of loneliness

Loneliness is a potent but little understood risk factor for broad-based morbidity and mortality. We review five social neurobehavioral mechanisms that may account for this association. The evidence suggests that different mechanisms explain short-term and long-term effects, and that the long-term effects operate through multiple pathways. Implications for the design of interventions are discussed.
