A new, short, and easily administered Risk Propensity Scale (RPS) is introduced that measures general risk‐taking tendencies. This paper investigates the reliability and discriminant validity of the RPS. The RPS provided scores that yielded a good internal reliability coefficient and adequate test–retest reliability, and the scores correlated moderately to well with those of the Everyday Risk Inventory and the short Sensation‐Seeking Scale. The correlation with the scores from other scales (Need for Cognition scale, Need for Structure scale, and 2 self‐esteem scales) was low to moderate, indicating good discriminant validity. The findings are discussed in relation to risk‐perception research using gambling experiments and in relation to their usefulness for risky decision‐making research. 相似文献

The goal was analysis of the perceptual-cognitive skills associated with sport performance in orienteering in a sample of 22 elite and 17 nonelite runners. Variables considered were memory, basic orienteering techniques, map reading, symbol knowledge, map-terrain-map identification, and spatial organisation. A computerised questionnaire was developed to measure the variables. The reliability of the test (agreement between experts) was 90%. Findings suggested that competence in performing basic orienteering techniques efficiently was a key variable differentiating between the elite and the nonelite athletes. The results are discussed in comparison with previous studies. 相似文献

Through two experiments, the study sought to emphasize the usefulness of the visual and kinesthetic imagery in mental practice. In Experiment 1, it was hypothesized that when the task to be learned through mental practice necessitates the reproduction of a form by drawing, the visual image, which provides a wide span of apprehension, is more suitable than the kinesthetic image. On the other hand, the kinesthetic image that supplies inputs from the muscles' positions and movements should be more appropriate for the acquisition of the duration of the drawing. In Experiment 2, it was hypothesized that the task, transformed into a motor task necessitating minute coordination of the two hands, would benefit more from kinesthetic imagery. To have optimal control over what was actually experienced during mental practice, the participants' imagery skills were measured. The participants also benefited from prior imagery training. The results demonstrate that when using mental practice to initially acquire a task, visual imagery is better for tasks that emphasize form while kinesthetic imagery is better for those tasks that emphasize timing or minute coordination of the two hands. 相似文献

Desire for control (DC) or need for control has frequently been proposed as an important personality characteristic and as a possible crucial moderator within the fields of achievement, psychological adaptation, stress, and health. However, unlike locus of control, hardly any effort has been undertaken to assess the construct. An exception is the work of Burger and Cooper on the Desirability of Control Scale ( 1979 ). In the present study, the psychometric properties of a Dutch version of the DC scale were tested in three different samples (total N = 1044). Furthermore, relationships between DC, its subscales, and various psychological personality and outcome measures were examined. The results show that the psychometric properties of the original DC scale could be successfully transposed to the Dutch version. Furthermore, factor analyses (PCA) led to the construction of three reliable subscales: ‘control others’ (desire to be in charge of and control others), ‘control self’ (desire to control one's own life), and ‘relinquish control’ (desire to leave others in control). The pattern of relationships with convergent and outcome variables supports the interpretation of these subscales. For ‘control others’, as for the total DC scale (i.e. a total of all 20 items), the emphasis of these relationships was on dominance, active coping, and psychological adjustment. ‘Control self’ was mainly related to self‐sufficiency and independence, while ‘relinquish control’ was clearly associated with passive coping and poor psychological adjustment. In summary, the DC scale appears to be a psychometrically sound instrument to assess desire for control and its subdimensions. Copyright © 2002 John Wiley & Sons, Ltd. 相似文献

For any given number of factors, Minimum Rank Factor Analysis yields optimal communalities for an observed covariance matrix in the sense that the unexplained common variance with that number of factors is minimized, subject to the constraint that both the diagonal matrix of unique variances and the observed covariance matrix minus that diagonal matrix are positive semidefinite. As a result, it becomes possible to distinguish the explained common variance from the total common variance. The percentage of explained common variance is similar in meaning to the percentage of explained observed variance in Principal Component Analysis, but typically the former is much closer to 100 than the latter. So far, no statistical theory of MRFA has been developed. The present paper is a first start. It yields closed-form expressions for the asymptotic bias of the explained common variance, or, more precisely, of the unexplained common variance, under the assumption of multivariate normality. Also, the asymptotic variance of this bias is derived, and also the asymptotic covariance matrix of the unique variances that define a MRFA solution. The presented asymptotic statistical inference is based on a recently developed perturbation theory of semidefinite programming. A numerical example is also offered to demonstrate the accuracy of the expressions.This work was supported, in part, by grant DMS-0073770 from the National Science Foundation. 相似文献

We tested the hypothesis that the relationship between team climate and team performance is moderated by climate strength. The study sample was composed of 155 bank branches, and a two‐wave panel design was implemented. We measured four team climate facets (support, innovation, goal achievement and enabling formalization). We obtained two subjective indicators of team performance (ratings provided by team members and by team managers) and a financial indicator of team performance. Seven out of the 12 interaction effects tested were statistically significant and showed the expected sign. When financial team performance was the criterion, only the interaction term was significant. This suggests that only strong climates are related to financial team performance over time. 相似文献

This paper discusses the method when an argument is refuted by a parallel argument since the flaw of the parallel argument
is clearly displayed. The method is explicated, examined and compared with two other general methods.

ABSTRACT— Are the kinds of abnormal cross-modal interactions seen in synaesthesia or following brain damage due to hyperconnectivity between or within brain areas, or are they a result of lack of inhibition? This question is highly contested. Here we show that posthypnotic suggestion induces abnormal cross-modal experience similar to that observed in congenital grapheme-color synaesthesia. Given the short time frame of the experiment, it is unlikely that new cortical connections were established, so we conclude that synaesthesia can result from disinhibition between brain areas. 相似文献

ABSTRACT— How does the brain respond to statements that clash with a person's value system? We recorded event-related brain potentials while respondents from contrasting political-ethical backgrounds completed an attitude survey on drugs, medical ethics, social conduct, and other issues. Our results show that value-based disagreement is unlocked by language extremely rapidly, within 200 to 250 ms after the first word that indicates a clash with the reader's value system (e.g., "I think euthanasia is an acceptable/unacceptable…"). Furthermore, strong disagreement rapidly influences the ongoing analysis of meaning, which indicates that even very early processes in language comprehension are sensitive to a person's value system. Our results testify to rapid reciprocal links between neural systems for language and for valuation. 相似文献
