Factors affecting developmental changes in the speed of processing

Although many studies have found developmental changes in the speed of various processes, they have potentially confounded the subject's age with his knowledge of the task domain and use of strategies. In this study, the strategies used by the subject and his domain knowledge were independently assessed by a number of tasks. Subsequently, processing rate measures were obtained for a task (the “same/different” judgment task of simultaneously presented stimuli) in which domain knowledge was manipulated independently of age while controlling for strategy usage. It was found that the usual adult superiority in speed of processing could be markedly reduced if children possessed equivalent amounts of domain knowledge and this effect was domain specific. Further, it was found that differences in knowledge affected processing rates in both knowledgeable adults and children and to about the same extent. It was concluded that some part of the typical adult superiority in processing rate was due to knowledge differences.     

Multi-attribute utility analysis using the promes approach

Traditional utility analyses have focused on the economic value of increased job performance. While providing a great deal of information to decision makers, such approaches fail to account for other potentially critical outcomes of implementing a selection system (e.g. legal exposure). This paper proposes a new method for incorporating multiple outcomes in utility analysis. An example shows how to incorporate economic gains due to job performance, legal exposure, effect on protected groups, and organizational image in the decision to implement a new selection system. Integrating these four outcomes into utility analysis captures managerial policy that will allow examination of the process of using utility information to aid decision making. In addition, the method is amenable to use of sensitivity, breakeven, and Monte Carlo analyses advocated by utility researchers (Boudreau, 1991).     

Estimating the impact of variable costs on SDy in complex situations

The inclusion of variable costs when estimating the standard deviation of job performance in dollars has been the basis for a number of highly important advances in utility analysis (e.g. Boudreau, 1983; Boudreau & Berger, 1985). However, no studies have shown the feasibility of incorporating variable costs in situations where multiple types of costs might require global estimation of variable costs. Results obtained from a nationwide sample of insurance personnel indicated that global estimates of variable costs were feasible to obtain in such complex situations but that those costs were not a fixed percentage of the value of job performance. Judges reported that the most important inputs of information into their estimates of the value of job performance in dollars were performance and output as well as initiative of the job holder. Surprisingly, salary related information was not reported as a relatively important input.The authors wish to thank Patricia G.

Two scales for measuring patients' perceptions for coercion during mental hospital admission

Legal and extra-legal coercion are pervasive in mental hospital admission and there are sharp disputes about its appropriate role. This article presents two scales for measuring psychiatric patients' perceptions of coercion during hospital admission and reports data on these scales' internal consistency. We measure patients' perceptions of coercion by asking questions, in either an interview or questionnaire format, about their experience of lack of control, choice, influence, and freedom in hospital admission. Patients' responses to questions about their perceptions of coercion were highly internally consistent. The internal consistency of the scale was robust with respect to variation in site, instrument format, patient population, and interview procedure. Correspondence analysis was used to construct two numerical scales of perceived coercion.     

The effect of Method Variance on Relationships Between the Work Ethic and Individual Difference Variables

A great deal of research relating the work ethic to other individual difference variables has been conducted using questionnaires to measure all the variables. Many researchers believe that using a single method of measurement for multiple constructs results in artificially inflated correlations. A Confirmatory Factor Analysis of the work ethic, locus of control, and conscientiousness reveals that approximately 16% of the variance in measures of these constructs is a function of the method of measurement. This suggests that correlations in work ethic research based on only one method of measurement may be overstated.     

医疗纠纷处理中若干伦理问题的思考

医疗纠纷的增势和处理难已成为众所周知的事实。但是,在医疗纠纷处理中存在着医患关系的信任性、医疗事故鉴定的公正性和经济裣的合理笥是思考的伦理问题。只要医患双方、乃至社会对诸如医疗行为是否等同于一般的服务行为、病人权益是否等同于消费者权益、医疗事故鉴定是不是医医相护、经济裣能不能实行等价赔偿原则、医疗差错要不要给予经济补偿等有效为统一的认识,就会有利于医疗纠纷的处理,有利于维护医患双方的合法权益,有利     

The effect of stress on the suppression of erroneous competing responses

Abstract Evidence exists that the intention to perform certain cognitive tasks activates, unintentionally, competing responses and computations that intrude on the performance of the intended tasks. For the intended task to be performed effectively, such intrusions must be controlled. Two experiments were carried out to test the hypothesis that stress heightens the difficulty of exercising effective control over erroneous competing responses, a possible explanation of decrements in the performance of cognitive tasks under stress. Participants performed four tasks, which contained features that could potentially prime or activate erroneous responses. The results demonstrated that the interference of these features with performance was more pronounced among stressed than among less-stressed participants. The need for a more comprehensive theory of the effects of stress on information processing is discussed.
