The purpose of the study was to investigate occupational stress among Chinese factory workers (N=342), from three cities of South East China, using the shortened version of the Occupational Stress Indicator (OSI)-2. The results showed that the reliabilities and predictive validity of the OSI-2 subscales and other subscales used for the study were reasonably high. Quite a high percentage of workers perceived high work pressure. The main sources of stress were intrinsic to the job; and the coping strategies that were most frequently used to tackle stress were “control” methods. In addition, “satisfaction on environmental condition” seemed to be a common predictor for job satisfaction, and mental and physical well-being. The logical relationships between job satisfaction, mental well-being and physical well-being in Chinese workers have provided support to the findings obtained in Western countries.  相似文献

追踪作业中几种心理负荷评估指标敏感性的研究   总被引:1,自引:0,他引:1  
本研究在模拟追踪作业情境下 ,对主任务绩效测定、主观评定和若干生理测量在心理负荷评估中的敏感性进行了实验。实验采用重复测量的被试者内设计 ,2 0名被试 (男女各半 )在六档负荷下分别从事五分钟追踪作业。所选用的指标有追踪作业平均误差距离、追踪警告次数、主观负荷评定、心率、心率变异和血压。结果发现 :1主任务绩效在评估追踪作业心理负荷中具有最高的敏感性 ,主观评定次之 ,心率变化率和心率变异变化率也随负荷变化 ,血压指标随负荷变化的趋势不明显 ;2除血压指标外 ,其余各指标之间均存在明显的相关 ,这提示它们在评估追踪作业心理负荷中具有较大的可靠性。  相似文献

We conducted a functional assessment of problem behaviors of 2 students with developmental disabilities in their classroom environments. Results of the assessments showed that although there were more tantrums in demand than in no-demand conditions, the function of the behavior was to gain attention (positive reinforcement) rather than to avoid or escape demands (negative reinforcement); demand conditions apparently served a discriminative function for the availability of attention. Therefore, intervention was based on the positive reinforcement hypothesis, resulting in a substantial reduction of tantrums for both subjects.  相似文献

This case study describes initially unsuccessful attempts to use the delayed-cue procedure to teach conditional discriminations to an individual with moderate mental retardation. The task was matching printed-word comparison stimuli to dictated-name sample stimuli. In three experiments, the subject typically waited for the delayed cue unless differential responses to the dictated samples (repeating the sample names) were required. Hence, the study provides an example of a way to make the delayed-cue method more effective. The stimulus control bases for the results are discussed.  相似文献

运用规则空间模型识别解题中的认知错误   总被引:13,自引:1,他引:12  
余嘉元 《心理学报》1995,28(2):196-203
运用规则空间模型识别学生解题中的认知错误,该模型将认知心理学,项目反应理论和数据库的代数理论相结合,将被试的二值反应模式映射为笛卡尔乘积空间的一组序偶,然后计算被试和错误规则在该空间的代表性位置之间的马氏距离,并通过贝叶斯决策准则划分被试的错误类型,根据644名中学生对30个数学题目的反应,识别出其中86%的学生可以被划分人18种认知错误类型中。  相似文献

Van Rees  M. Agnes 《Argumentation》1995,9(2):343-362
In this article, the conceptual instrument that pragma-dialectical argumentation theory offers is elaborated for the analysis and evaluation of problem-solving discussions. The elaboration is aimed expressly at taking into account the discussion character of the discourse, in order to show how the developing process evolves and what the obstacles are therein. In addition, it focuses expressly on the verbal behaviour of the participants and on showing how this behaviour controls the evolving process. The analysis and evaluation is based on insights and methods of conversational analysis and discourse analysis. One fragment of a problem-solving discussion is analysed and evaluated.  相似文献

This paper examines those children receiving mental health services in Puerto Rico, their demographic and psychosocial characteristics, and describes service providers and nature of facilities. The survey was done on a probability sample of children ages 4 through 16 across the island of Puerto Rico (N=777). Need for services was clinically defined as presence of a DSM-III diagnosis and functional impairment. The overall rate of service utilization for Puerto Rican children was 6% (26.2% of definite cases and 5.1% of probable cases). In most cases services were provided by psychologists and/or social workers, and they were mainly provided in schools and general medical facilities. In over 60% of the children assessed as cases, who did not receive services, the reason, given by the parent was that they considered the problem not serious. Factors associated with service utilization were measures of psychopathology, teacher's perceived need, and parental rates of criticism and hostility. These findings suggest that there is a need for more research on the motivating factors for service use (impairment and parental criticism). Teachers could benefit from receiving special training to help them readily recognize behavioral problems in children, communicate them to parents and set up services alternatives.  相似文献
