Twenty men and twenty women were tested to determine patterns of latent hostility toward the Deity figure with a view governed by sex difference. It was found that men exhibited a consistently rigid pattern while women tended to move from lower to higher means on the “B” or benevolence scale. There was little differentiation on the “P” or potency scores. The technique utilized ink blot interpretations with subsequent ranking from the one most, to the one least, suggesting God. This attachment of symbol on a known factor to one of an unknown dimension has been labeled the technique of symbolic equivalence.  相似文献

The study aims were to identify the interpersonal style characteristics of Vietnam Era veterans by comparison with World War II veterans. The sample included 3,075 veterans in treatment in 47 VA health care facilities. Patients were categorized as medical-surgical, psychiatric, and drug addicted, and divided by age into the 24 or less, and the 45 to 55 age groups. The measuring device was the Interpersonal Style Inventory. Group differences on the 17 scores were tested by discriminant function analyses. The Vietnam Era veterans were found to be more rebellious, mistrustful, adventure-seeking and expedient than the older veterans.  相似文献

Richard Hare argues that the fundamental assumptions of Kant's ethical system should have led Kant to utilitarianism, had Kant not confused a norm's generality with its universality, and hence adopted rigorist, deontological norms. Several authors, including Jens Timmermann, have argued contra Hare that the gap between Kantian and utilitarian/consequentialist ethics is fundamental and cannot be bridged. This article shows that Timmermann's claims rely on a systematic failure to separate normative and metaethical aspects of each view, and that Hare's attempt to bridge the gap between Kantian and consequentialist ethics is immune to Timmermann's criticisms. Furthermore, the term “Kantian ethics” is often misleading, and should typically be qualified as either “Kantian rationalism” or “Kantian deontology” in order to avoid confusions of the sort Timmermann falls into.  相似文献

Maxwell and Cole (2007) Maxwell, S. E. and Cole, D. A. 2007. Bias in cross-sectional analyses of longitudinal mediation. Psychological Methods, 12: 2344. [Crossref], [PubMed], [Web of Science ®] [Google Scholar] showed that cross-sectional approaches to mediation typically generate substantially biased estimates of longitudinal parameters in the special case of complete mediation. However, their results did not apply to the more typical case of partial mediation. We extend their previous work by showing that substantial bias can also occur with partial mediation. In particular, cross-sectional analyses can imply the existence of a substantial indirect effect even when the true longitudinal indirect effect is zero. Thus, a variable that is found to be a strong mediator in a cross-sectional analysis may not be a mediator at all in a longitudinal analysis. In addition, we show that very different combinations of longitudinal parameter values can lead to essentially identical cross-sectional correlations, raising serious questions about the interpretability of cross-sectional mediation data. More generally, researchers are encouraged to consider a wide variety of possible mediation models beyond simple cross-sectional models, including but not restricted to autoregressive models of change.  相似文献

Theories of decision-making have traditionally been constrained by reaction time data. A limitation of reaction time data, particularly for studying the temporal dynamics of cognitive processing, is that they index only the endpoint of the decision making process. Recently, physical reaching trajectories have been used as proxies for underlying mental trajectories through decision space. We suggest that this approach has been oversimplified: while it is possible for the motor control system to access the current state of the evidence accumulation process, this access is intermittent. Instead, we demonstrate how a model of arm movements that assumes intermittent, not continuous, access to the decision process is sufficient to describe the effects of stimulus quality and viewing time in curved reaching movements.  相似文献

After an exam in which the order of question presentation was varied on the basis of pre-established difficulty levels, student perceptions of the test, course, and instructor were compared. Perceptual scores for 68 Ss across nine evaluative factors were analyzed. The hypothesized existence of a primacy/recency halo effect on perceptual bias received partial support. Five of nine factors were significant in the hypothesized direction at the .05 level.  相似文献

The interrelationships between gender, race, and academic achievement levels were examined. Third-grade students (N = 107) were randomly selected from the poulation of a desegregated metropolitan school district in the deep South. The school district provided the researchers with the gender, race, and California Achievement Test (CAT) score of each student. Results showed that, although the average scores for all subjects on all CAT areas exceeded the national third-grade average, females and whites outperformed males and blacks in all 11 academic areas. The results support the Grant-Sleeter (1986) thesis that important information is neglected if race and gender are treated discretely.  相似文献

This study explored the psychosocial mechanisms of change associated with differences in levels and linear change of adolescents' global life satisfaction across a 2-year time period. Based on a theoretical model proposed by Evans (1994), this study tested the relations between selected personality (i.e., extraversion and neuroticism) and environmental (stressful life events) variables and global life satisfaction when mediated by internalizing and externalizing problems. The results suggested support for internalizing problems as a mediator of the relationship of personality and environmental variables with life satisfaction. Pathways mediated by internalizing problems significantly predicted levels and linear change of life satisfaction across a 2-year time span. Furthermore, pathways mediated by externalizing problems significantly predicted the level but not the linear change of life satisfaction. Thus, behavior problems and their antecedents appear to relate significantly to adolescents' perceptions of their quality of life. Implications for adolescent mental health promotion were discussed.  相似文献

Our objective was to apply the rigorous test developed by Browne (1992) to determine whether the circumplex model fits Big Five personality data. This test has yet to be applied to personality data. Another objective was to determine whether blended items explained correlations among the Big Five traits. We used two working adult samples, the Eugene-Springfield Community Sample and the Professional Worker Career Experience Survey. Fit to the circumplex was tested via Browne's (1992) procedure. Circumplexes were graphed to identify items with loadings on multiple traits (blended items), and to determine whether removing these items changed five-factor model (FFM) trait intercorrelations. In both samples, the circumplex structure fit the FFM traits well. Each sample had items with dual-factor loadings (8 items in the first sample, 21 in the second). Removing blended items had little effect on construct-level intercorrelations among FFM traits. We conclude that rigorous tests show that the fit of personality data to the circumplex model is good. This finding means the circumplex model is competitive with the factor model in understanding the organization of personality traits. The circumplex structure also provides a theoretically and empirically sound rationale for evaluating intercorrelations among FFM traits. Even after eliminating blended items, FFM personality traits remained correlated.  相似文献
