In this study a social comparison model is constructed that predicts objectively recorded absence frequency among male Dutch blue-collar workers from a metal factory in the Netherlands. By employing LISREL, the model is developed (tested and revised) in Plant North (N = 254), and successfully cross-validated in Plant South (N= 199). The study demonstrates the impact of two social comparison processes upon absenteeism. Absenteeism is the result of: (a) the perception that one is less well-off than one's colleagues on several job aspects, and (b) the adjustment of one's personal absence norm to that of the work group. In addition, our study reveals that, rather than being absent or having tolerant absence norms, employees may develop feelings of resentment in response to perceived inequity and a tolerant group absence norm. It is concluded that social comparison theory enhances our understanding of absenteeism. 相似文献

Two studies were conducted to investigate the potential effects on workrelated behavior of one environmental variable: pleasant fragrances. In Study 1, participants performed a word construction task under low or high stress while in the presence or absence of pleasant fragrances. Performance was significantly enhanced by fragrance in both stress conditions. In addition, exposure to pleasant fragrances significantly increased performance on an additional task (decoding written messages) completed by participants following exposure to stress. In Study 2, both exposure to pleasant fragrances and receipt of a small gift increased performance on the same word construction task used in Study 1. In addition, fragrance and a gift increased participants' willingness to engage in both immediate and delayed helping. Together, the results of these studies offer support for the view that pleasant fragrances can influence work-related behavior, and that such effects may be mediated, at least in part, by increments in positive affect. 相似文献

Reports of community alienation and high ingroup identification in the police suggest that they are a particularly ethnocentric group. To empirically test this hypothesis, a sample of urban police officers was surveyed to ascertain their social identity pattern. Results indicated a high level of peer solidarity, community alienation differentiated on the basis of race and social class, and the perception that the source of alienation lies more with the community than with the officers themselves. A central finding was that those officers who identified most strongly with peers also tended to report lower levels of alienation from the community groups. This finding, in conjunction with unremarkable levels of authoritarianism and perceived stress in the sample, challenges the stereotype of the ethnocentric, authoritarian, and stressed out police officer. Results are placed within a novel framework for understanding the police solidarity phenomenon, and implications for police-community relations are discussed. 相似文献

A clinical observation regarding patients who complain about feeling left out and/or second best provides the framework for this paper. What is expressed is a form of separation anxiety coupled with a loser self-concept. It is suggested that these patients represent a milder form of the moral masochism. Early theoretical formulations include Freud and his emphasis on the superego and Reich's emphasis on the masochist's fear of being left alone. Kramer's little man phenomenon is an example of a more current theoretical formulation which takes account of the complexities of the ego, and composite self and identity in the clinical phenomena observed. A case of a latency-aged child is provided. 相似文献

Understanding the mental processes involved in suffering has always been the best basis for communication between patients
and caretakers. In this paper we are concerned first with acknowledgment of the existence, generally unknown, and the effects,
generally unrecognized, of the hypnotic processes that occur in many forms of suffering, and second with developing our thesis
that the understanding and use of hypnotic principles can greatly enrich the chaplain's capacity to alleviate suffering. In
this brief presentation we will confine our discussion to the teaching of hypnosis as a virtual necessity in modern clinical
training for chaplains. Comments and considerations will precede and follow an outline of the course presently offered at
Lenox Hill Hospital [but we cannot here attempt to discuss or explain the fundamentals of hypnotic process or any other aspects
of the course content itself]. A basic bibliography is appended for those who wish to know more about hypnosis itself. 相似文献

In this contribution we show how neuroimaging methods can augment behavioural methods to discover processing stages. Event Related Brain Potentials (ERPs), Brain Electrical Source Analysis (BESA) and regional changes in cerebral blood flow (rCBF) do not necessarily require behavioural responses. With the aid of rCBF we are able to discover several cortical and subcortical brain systems (processors) active in selective attention and memory search tasks. BESA describes cortical activity with high temporal resolution in terms of a limited number of neural generators within these brain systems. The combination of behavioural methods and neuroimaging provides a picture of the functional architecture of the brain. The review is organized around three processors: the Visual, Cognitive and Manual Motor Processors. 相似文献

Single-route models attribute stimulus-response compatibility effects to the difficulty of translation from stimulus to response. Dual-route models propose that compatibility effects reflect in part an additional direct, or automatic, activation route. Selected findings from three lines of research are reported that converge to provide evidence consistent with the view that the automatic activation route plays a role in compatibility effects. The data suggest that the activation produced via this route by relevant stimulus attributes influences response selection only when all mappings of stimuli to responses are known to be compatible. 相似文献

The United States Supreme Court in Daubert v. Merrell Dow Pharmaceuticals (1993) directed federal trial judges to preliminarily evaluate the scientific bases of proffered expert evidence. This article presents a decision flowchart for evaluating psychometric data, and attempts to operationalize existing evidentiary standards in hybrid (part science/part law) terms. The resulting framework should better assist courts and forensic experts to understand, evaluate, and apply scientific reasoning in determining the admissibility and probative value of psychometric evidence. 相似文献
