This paper reports two companion studies which establish that there is a significant relationship between an individual's personality characteristics and his pattern of job-seeking behavior. Individuals who are tough-minded, independent and nonneurotic had specified job goals and self-actualized behavior. They were highly successful in obtaining jobs. Individuals who were sensitive, dependent and neurotic had vague goals and passive behavior. They failed to get jobs. Individuals who exhibited a mixture of the cited characteristics and behavior were also exploring career options. They had a modicum of success in obtaining jobs. Job-seeking behavior as a process of vocational development is discussed.  相似文献

Ethical problems are related to computer data bases, containing data on individuals and groups of persons, as well as to computer knowledge bases, containing general rules and elements of expert systems.In the present essay the following conclusions are made regarding computer data bases: privacy, security, and confidentiality of medical computer data bases should be ensured. This duty should rest with physicians in hospitals. The principle of informed consent should be applied to gathering information which is to be stored and processed by computers. Information stored in computer data bases should not be used for purposes for which the subjects (patients as well as personnel) have not given their consent. In order to decrease the possibility of misuses of medical data bases containing information on individuals, these registers should not be linked to other central data bases.  相似文献

Women who had completed the SVIB-W as freshmen in college were contacted 13 to 21 years later and were classified as career (N = 236) or homemaker (N = 527) oriented on the basis of their actual work experiences. Significant differences between the groups were found on 25 of the 44 occupational scales, one of the three nonoccupational scales, and four of the 19 basic interest scales. The interests of the homemaker oriented women were more similar to the interests of women in business, nonprofessional, and home economics occupations while the interests of the career oriented women were more similar to the interests of women in the verbal-linguistic, verbal scientific, and scientific occupations. The results are discussed in terms of previous research and Holland's Occupational Classification system.  相似文献

Explicit information-seeking actions are needed to evaluate alternative actions in problem-solving tasks. Information-seeking costs are often traded off against the utility of information. We present three experiments that show how subjects adapt to the cost and information structures of environments in a map-navigation task. We found that subjects often stabilize at suboptimal levels of performance. A Bayesian satisficing model (BSM) is proposed and implemented in the ACT-R architecture to predict information-seeking behavior. The BSM uses a local decision rule and a global Bayesian learning mechanism to decide when to stop seeking information. The model matched the human data well, suggesting that adaptation to cost and information structures can be achieved by a simple local decision rule. The local decision rule, however, often limits exploration of the environment and leads to suboptimal performance. We propose that suboptimal performance is an emergent property of the dynamic interactions between cognition and the environment.  相似文献

We applied SMR/theta neurofeedback (NF) training at central sites of 20 Israeli children aged 10-12 years, half boys and half girls. Half of the subjects received C3 training and the other half C4 training, consisting of 20 half-hour sessions. We assessed the effects of training on lateralized lexical decision in Hebrew. The lateralized lexical decision test reveals an independent contribution of each hemisphere to word recognition (Barnea, Mooshagian, & Zaidel, 2003). Training increased accuracy and sensitivity. It increased left hemisphere (LH) specialization under some conditions but it did not affect interhemispheric transfer. Training did affect psycholinguistic processing in the two hemispheres, differentially at C3 and C4. Training also increased hemispheric independence. There were surprising sex differences in the effects of training. In boys, C4 training improved LH accuracy, whereas in girls C3 training improved LH accuracy. The results suggest that the lateralized NF protocol activates asymmetric hemispheric control circuits which modify distant hemispheric networks and are organized differently in boys and girls.  相似文献

In genetic counseling, facilitation of autonomous decision-making is seen as a primary aim and respect for autonomy is used to justify a nondirective counseling approach whereby clients are free to make their own choices after being given all necessary information. However in the genetic counseling literature, autonomy as a concept appears to be interpreted variably and often narrowly. We offer a practical account of autonomy that is coherent, consistent and philosophically defensible for the genetic counseling setting. At the same time we demonstrate how nondirective counseling may serve to frustrate rather than facilitate client autonomy. We suggest that promoting purposeful dialogue rather than counseling that is nondirective is more conducive to client autonomy.  相似文献

Human decision-making is underpinned by distinct systems that differ in flexibility and associated cognitive cost. A widely accepted dichotomy distinguishes between a cheap but rigid model-free system and a flexible but costly model-based system. Typically, humans use a hybrid of both types of decision-making depending on environmental demands. However, children's use of a model-based system during decision-making has not yet been shown. While prior developmental work has identified simple building blocks of model-based reasoning in young children (1–4 years old), there has been little evidence of this complex cognitive system influencing behavior before adolescence. Here, by using a modified task to make engagement in cognitively costly strategies more rewarding, we show that children aged 5–11-years (N = 85), including the youngest children, displayed multiple indicators of model-based decision making, and that the degree of its use increased throughout childhood. Unlike adults (N = 24), however, children did not display adaptive arbitration between model-free and model-based decision-making. Our results demonstrate that throughout childhood, children can engage in highly sophisticated and costly decision-making strategies. However, the flexible arbitration between decision-making strategies might be a critically late-developing component in human development.  相似文献

ObjectivesObtaining education is an important milestone in athletes’ preparation for their professional career after sport. Literature indicates that combining school and sport is not an easy task for many aspiring youth athletes. It has been proposed that career adaptability, which refers to psychosocial resources enabling individuals to solve complex occupational transitions, present and anticipated vocational development tasks, and career related challenges could be a relevant concept for applied work with student-athletes. In this study, we examined whether there are distinct developmental profiles of career adaptability among adolescent athletes across the upper secondary school years. We also investigated the associations between career adaptability and sport withdrawal and academic achievement.Design and methodsA total of 391 Finnish-speaking student-athletes completed the questionnaire on career adaptability (Career Adapt-Abilities Scale – Dual Career Form; Ryba & Aunola, 2015; Ryba et al., 2017) at the beginning and end of upper secondary school. The participants’ background information about their sport participation and grade point average were collected upon completion of each grade of upper secondary school. The data were analysed using cluster analysis, cross-tabulation, and one-way analysis of variance.ResultsFour distinct adaptability profiles were identified: higher adaptability, lower adaptability, increasing adaptability, and decreasing adaptability. Higher and lower adaptability profiles showed stable levels of adaptability across time, whereas the adaptability level either increased or decreased in the other two profiles. Student-athletes with a lower career adaptability profile were overrepresented among those who withdrew from competitive sports, and they reported lower grade point averages than those with higher scores of career adaptability.ConclusionsHigh scores of career adaptability were associated with high grades, whereas low scores of career adaptability were associated with low grades and a probability to withdraw from competitive sport. Therefore, it is recommended that career adaptability be considered as important self-regulation resources for sustaining dual career pathways over time.  相似文献

标准参照测验中的信度估计公式   总被引:4,自引:0,他引:4  
陈希镇 《心理学报》1996,29(4):436-442
标准参照测验是与常模参照测验不同的一种测验,在标准参照测验中,一个人在测验上的分数不是和他人相比较而是和某个已经设定的标准作比较。如果测验是从某功课论域中随机抽样构造而成,则使用者希望知道考生在这份测验上的观测分数与其在该功课论域上的分数(假如已知)的接近程度;如果使用者想根据测验分数对考生作掌握分类,则他们关心这个推断与假设考生论域分数已知时所作推断一致程度有多高。本文对这两个问题的信度估计进行探讨,得到几个有用的估计公式。  相似文献
