Aspects of March and Simon’s (1958) subjective expected utility model and a prediction of Lee and Mitchell’s (1994) unfolding model of voluntary employee turnover were tested. A policy capturing simulation that varied high, moderate, and low levels of five job characteristics was used to model voluntary turnover decision processes for 532 nurses. Survey measures of these job characteristics obtained over the next 2 years were multiplied by weights derived from nurse simulations to yield turnover likelihood estimates. These estimates exhibited 80%, 127%, and 190% more predictive power (depending on turnover operationalization) than post-employment survey estimates of turnover intention, job satisfaction, and job availability. Groups of nurses with homogeneous voluntary turnover decision models were also identified, though no groups with homogeneous job perceptions were observed. Evidence suggested nurses responded to “shocks” as predicted. March and Simon’s model of voluntary turnover was supported and implications drawn for managing voluntary nursing turnover.  相似文献

An understanding of healthy families is essential to effective family therapy. As in medicine and psychiatry generally, there has been an emphasis on family psychopathology and dysfunction. An effort is made to rectify this by initially defining the concepts family and normal. The characteristics and tasks of families are examined. A review of the literature and research on healthy families is offered despite the sparseness of information directly focused on those systems. Methodological difficulties are outlined as background to a consideration of the research outcomes. There is general consensus that families that work well communicate clearly and often in a noisy fashion. Generational boundaries and subsystems are well defined. Decision making is effective and efficient. Healthy families are adaptive and able to cope with the passage of time and eventual loss of their members.  相似文献

On the basis of previous findings on the varying ability clinically to predict the outcomes of psychotherapy, this study is focussed on the judgmental processes of good and not-so-good judges. To chart the mechanisms of predictive accuracy, the relations between the ratings of each judge and the criteria have been modelled in terms of structural equations. Further, the predictions of one good and one not-so-good judge have been analysed by multiple regression, with aspects of patient information as independent variables. The analyses suggest that, compared to the not-so-good judge, the good judge utilises more information and has more adequate ideas about its validity but not about its internal correlational structure. While not neglecting secondary process thinking, the good judge still leaves room for intuitive, non formalised judgment and also utilises available information in a more discriminating, or radical, manner. The not-so-good judge appears as an overly conscious and cautious person, neglecting much valid information, not discriminating among the variables, and using negatively valid information positively.  相似文献

In the present paper an experimental design is introduced for the analysis of the conceptual categories used by subjects when stereotyping males and females. Subjects were asked to name as many familiar types of women and men as they could think of, and describe them in terms of various characteristic properties (e.g., traits, attitudes, interests, skills, and demographic features). The most frequently mentioned types were then sorted by a second sample according to their perceived similarity. Finally, a third group of subjects categorized the initial set of properties in terms of their relevance to either male or female types. Clustering and scaling analyses yielded a clear cut picture of the cognitive ordering principles underlying gender stereotypes. Distinct property clusters were found for the female and male types, underlining the important role of gender stereotypes in the knowledge base of the subjects.The authors would like to thank Kay Deaux for helpful comments on an earlier draft.  相似文献

Research using the diffusion model to decompose task-switching effects has contributed to a better understanding of the processes underlying the observed effect in the explicit task cueing paradigm: Previous findings could be reconciled with multiple component models of task switching or with an account on compound-cue retrieval/repetition priming. In the present study, we used two cues for each task in order to decompose task-switch and cue-switch effects. Response time data support previous findings that comparable parts of the switching effect can be attributed to cue-switching and task-switching. A diffusion model analysis of the data confirmed that non-decision time is increased and drift rates are decreased in unpredicted task-switches. Importantly, it was shown that non-decision time was selectively increased in task-switching trials but not in cue-switching trials. Results of the present study specifically support the notion of additional processes in task-switches and can be reconciled with broader multiple component accounts.  相似文献

Competencies have become a leading construct in human resource practices. However, empirical research on competencies has lagged behind resulting in a gap between practice and science. In this study, the focus was on the nature of competencies by examining the relationships of three competency dimensions with cognitive ability, personality and performance during assessment center exercises. Data of 932 applicants participating in a 1‐day selection procedure were used. Results showed that to assess the competency dimension Thinking psychologists focus on cognitive ability. To assess the competency dimension Feeling psychologists rely on performance during interview simulation exercises and on measures of personality. In assessing the dimension Power psychologists focus mainly on personality, although they also rely on cognitive ability and performance during interview simulation exercises.  相似文献

Children's performance on free labeling of prototypical facial expressions of basic emotions is modest and improves only gradually. In 3 data sets (N = 80, ages 4 or 5 years; N = 160, ages 2 to 5 years; N = 80, ages 3 to 4 years), errors remained even when method factors (poor stimuli, unavailability of an appropriate label, or the difficulty of a production task) were controlled. Children's use of emotion labels increased with age in a systematic order: Happy, angry, and sad emerged early and in that order, were more accessible, and were applied broadly (overgeneralized) but systematically. Scared, surprised, and disgusted emerged later and often in that order, were less accessible, and were applied narrowly.  相似文献

To what extent the IAT (Implicit Association Test, Greenwald et al., 1998) predicts racial and ethnic discrimination is a heavily debated issue. The latest meta‐analysis by Oswald et al. (2013) suggests a very weak association. In the present meta‐analysis, we switched the focus from the predictor to the criterion, by taking a closer look at the discrimination outcomes. We discovered that many of these outcomes were not actually operationalizations of discrimination, but rather of other related, but distinct, concepts, such as brain activity and voting preferences. When we meta‐analyzed the main effects of discrimination among the remaining discrimination outcomes, the overall effect was close to zero and highly inconsistent across studies. Taken together, it is doubtful whether the amalgamation of these outcomes is relevant criteria for assessing the IAT's predictive validity of discrimination. Accordingly, there is also little evidence that the IAT can meaningfully predict discrimination, and we thus strongly caution against any practical applications of the IAT that rest on this assumption. However, provided that the application is thoroughly informed by the current state of the literature, we believe the IAT can still be a useful tool for researchers, educators, managers, and students who are interested in attitudes, prejudices, stereotypes, and discrimination.  相似文献

Predictors of self-reported suicide attempts were studied cross-sectionally and prospectively in order to discern which variables may account for the gender difference in such reports. A representative sample of Norwegian students (N= 9,679) in grades 7-12 were followed from 1992 to 1994. More girls (10.4%) than boys (6.0%) reported a previous attempt and more girls (3.3%) than boys (1.9%) reported an attempt during the study period. The gender difference in previous suicide attempts was significantly reduced when depressed mood was controlled, and was no longer significant when disordered eating was included. There was no gender difference in future attempts when previous attempts, depressed mood, physical appearance, pubertal timing, and romantic involvement were controlled. Girls' higher level of risk factors may account for their higher level of self-reported nonfatal suicidal behavior.  相似文献

This study examined how perceptions of underlying offender motives affect victims’ emotional and behavioral reactions toward their offender. Perceived offender motives of malice and greed were embedded in a cognition–emotion–behavior model based on theories of attribution, forgiveness and revenge, and tested in the context of social undermining. Findings suggested that victims distinguished between offender malice and greed, and that these attributions shaped subsequent emotional reactions, which in turn demonstrated independent relations with revenge, avoidance, and reconciliation.  相似文献

A procedure is presented for the evaluation of single-point estimates of true and false positives without strong underlying parametric assumptions. The method is based upon the area operating characteristic and the Green area rule. Estimates of sampling error are also available. The procedure is extended to a strong one-parameter relation between true and false positives.  相似文献

This study is a direct replication of gaze-liking effect using the same design, stimuli and procedure. The gaze-liking effect describes the tendency for people to rate objects as more likeable when they have recently seen a person repeatedly gaze toward rather than away from the object. However, as subsequent studies show considerable variability in the size of this effect, we sampled a larger number of participants (N?=?98) than the original study (N?=?24) to gain a more precise estimate of the gaze-liking effect size. Our results indicate a much smaller standardised effect size (dz?=?0.02) than that of the original study (dz?=?0.94). Our smaller effect size was not due to general insensitivity to eye-gaze effects because the same sample showed a clear (dz?=?1.09) gaze-cuing effect – faster reaction times when eyes looked toward vs away from target objects. We discuss the implications of our findings for future studies wishing to study the gaze-liking effect.  相似文献

In this study, a series of nested models was tested to assess the extent to which the relationship between process-related justice and union participation is mediated by perceived union support and union commitment. Members of a steelworkers' local (N = 615) participated in the study. Fit indices most strongly supported a fully mediated model. Unlike previous research, process-related justice was operationalized as 2 distinct variables: procedural and interactional justice. Interactional justice was found to have a substantially stronger relationship with support perceptions than procedural justice. Results also indicated union support accounted for a greater amount of unique variance in union commitment than perceived union instrumentality. The results are discussed in relation to trust theory and the generalization of organization science across different types of organizations.  相似文献

This article contributes to the understanding of why the use of a frame-of-reference leads to increased criterion-related validity of personality inventories. Two competing explanations are described and tested. A between-subjects (N = 337) and a within-subject (N = 105) study are conducted to test the hypothesized effects of use of a frame of reference on reliability and validity. Regarding the effects on reliability, use of a frame of reference reduces within-person inconsistency (instead of between-person variability) in responding to generic items. Use of a frame of reference further leads to higher validity as a result of the reduction of between-person variability and within-person inconsistency. Yet, reducing these inconsistencies is not enough. It is also important to use a frame of reference that is conceptually relevant to the criterion. Besides implications for contextualized personality inventories, these results provide an explanation for the moderate validities of generic personality inventories.  相似文献

The "problem of three prisoners", a counterintuitive teaser, is analyzed. It is representative of a class of probability puzzles where the correct solution depends on explication of underlying assumptions. Spontaneous beliefs concerning the problem and intuitive heuristics are reviewed. The psychological background of these beliefs is explored. Several attempts to find a simple criterion to predict whether and how the probability of the target event will change as a result of obtaining evidence are examined. However, despite the psychological appeal of these attempts, none proves to be valid in general. A necessary and sufficient condition for change in the probability of the target event, following observation of new data, is proposed. That criterion is an extension of the likelihood-ratio principle (which holds in the case of only two complementary alternatives) to any number of alternatives. Some didactic implications concerning the significance of the chance set-up and reliance on analogies are discussed.  相似文献

The ecological principle of interdependence has been a guiding theme in our research and conceptualization. For the development of community psychology, academic and applied interest and networks must be integrated in ways which value the views and resources of both groups. This is the focus of Kelly's (1984) remarks. The dynamic interplay of ideas, data, and practices is likely to facilitate the collaboration between researchers and setting inhabitants which Trickett (1984) describes as the distinctive quality of community psychology. Common pathways of information exchange, joint responsibility for training future members of the field, and mutually enhancing role relationships are needed. Current channels of communication provide little ease of access or incentives for participation by psychologists in nonacademic settings. It thus becomes the reponsibility of all concerned community psychologists to use their organizational skills to redress this harmful imbalance (Kelly, 1984). For this to occur, however, we must take the initial steps of frankly recognizing differences in our folkways and organizational constraints, while also emphasizing our common values and assets. The largest threat to the field is external constraints from university and clinical service settings on the work that represents community psychology (Elias et al., 1984). If we are dividedor uninformed in the face of these environmental presses, we will never create the adaptive niche that community psychology needs to survive.  相似文献
