A significance test is proposed for determining whether a correlation coefficient is less than unity by an amount greater than that attributable to errors of measurement.  相似文献

The results of three empirical studies on the sampling fluctuation of centroid factor loadings are reported. The first study is based on data which happened to be available on 8 variables for 700 cases and which were factored to three factors for subsamples. The second study is based on fictitious data for 2500 cases which provided separate analyses on 25 samples for each of three situations: 5 variables, one factor; 5 variables, two factors; and 6 variables, three factors. The third study, based on real data for 9 variables and 7000 cases, involves separate factorization for 35 samples of 200 cases. The three studies agree in showing that the sampling behavior of first centroid factor loadings is much like that of correlation coefficients, whereas the sampling fluctuations for loadings beyond the first are disturbingly large.  相似文献

Many of us share a strong intuition that justification forces us to better understand the situations we face. And there is substantial evidence indicating that this is often the case. However, there is a growing body of research showing that, under certain circumstances, explanation and justification can impair performance on a variety of cognitive tasks. In the present research, the effects of justification on judgment of the soundness of analogies were examined. Subjects judged the quality of the match between pairs of stories with varying degrees of superficial and analogical similarity. Experimental subjects either provided reasons for their judgments or wrote recollections of the target stimuli. These subjects rated the match between stimulus pairs as more sound than did control subjects. Also, providing reasons led to poorer discrimination between superficially similar aspects of the stimuli and analogous aspects. Explanations of these findings are proposed, and implications for problem solving and confidence judgment are discussed.  相似文献

This paper attempts to integrate Sandler's object relations theory of transference with Langs theories regarding the centrality of framework issues in psychotherapy. The authors illustrate how modifications in the framework are the primary way in which a patient attempts to impose a role on the therapist—a role which is in keeping with the patient's internal object reactions and early pathogenic relationships. In addition, the authors demonstrate how a patient's attempts to impose a role on the therapist are often a reaction to the therapist's own modifications of the framework.The authors would like to thank Dr. Robert Langs for his editorial assistance.  相似文献

The goal of the present research is to demonstrate, and then alleviate, the role of thought suppression in depressing women’s math performance under stereotype threat. We hypothesize that when taking a math test, women (but not men) attempt to suppress thoughts of the math-related gender stereotype. Suppression leads to underperformance when it uses up cognitive resources. In Study 1, women underperform on a math test and show postsuppressional rebound of the stereotype when cognitive resources are reduced. In Study 2, women suppress the stereotype after a math test begins, but show rebound when the test is complete. In Study 3, making the stereotype irrelevant to the test improves performance and reduces postsuppressional rebound. In Studies 4 and 5, we test a strategy women can use to make suppression easier, and show that it restores math performance. Theoretical and practical implications are discussed.  相似文献

This study examines how several indicators of ability and achievement are associated with individual differences in preferences for job and organizational attributes. Results from a sample of 378 business and liberal arts students suggest that students with high cognitive ability and all types of high achievement place greater importance on interesting and challenging work than do other students. However, on other work attributes (e.g., job flexibility, pay practices, fast-track promotion systems), students with high cognitive ability and high academic achievement (i.e., grade point average) appear to have different preference patterns from those with high social achievement (e.g., extracurricular and leadership activities). Results are discussed in terms of implications for employers and future research.  相似文献

Results obtained from a novelty-preference procedure indicate that young infants possess abilities to organize objects into perceptual categories that have conceptual significance for adults. This work suggests that the initial construction of category representations is not dependent on language, formal instruction, or specialized processes, and that category development may proceed through a process of enrichment.  相似文献

The influential model of verbal working memory (WM) introduced by Baddeley and Hitch (Recent advances in learning and motivation. Academic, New York, 1974) comprised three interacting component parts; an executive controller and two subservient systems. The two subservient systems, one underpinning verbal processing and the other underpinning visual processing are themselves subdivided. In the verbal system, a passive phonological store is maintained by an active phonological loop, which is able to rehearse the material in the passive store. The visual working memory system has traditionally been thought of as having a similar architecture with a passive visual store being maintained by an active store, which codes in terms of movement over space. The paper discusses the evidence for this relationship in visuo-spatial WM and concludes that the architecture does not fit well with the experimental literature. A direction for future research is suggested.  相似文献

There has been a recent surge of interest in the question of how infants respond to the social attributes of race and gender information in faces. This work has demonstrated that by 3 months of age, infants will respond preferentially to same‐race faces and faces depicting the gender of the primary caregiver. In the current study, we investigated emergence of the female face preference for same‐ versus other‐race faces to examine whether the determinants of preference for face gender and race are independent or interactive in young infants. In Expt 1, 3‐month‐old Caucasian infants displayed a preference for female over male faces when the faces were Caucasian, but not when the faces were Asian. In Expt 2, new‐born Caucasian infants did not demonstrate a preference for female over male faces for Caucasian faces. The results are discussed in terms of a face prototype that becomes progressively tuned as it is structured by the interaction of the gender and race of faces that are experienced during early development.  相似文献
