Hispanic jurors' verdicts and whether these decisions were related to jurors' judgments of the credibility of the witness were the focus of this experiment. A prosecution witness testified in English or in Spanish with interpretation in English. Witnesses' speaking style systematically included hedges and hesitations or did not. Guilty verdicts were independent of language of testimony. Within Spanish‐interpreted conditions, jurors convicted the defendant 47% of the time in the absence of hedges and hesitations. When he hedged and hesitated, they convicted 34% of the time. This effect was complicated by a reliable Witness Hesitation × Juror Language Dominance interaction. These results are interpreted in the context of the courtroom impact of non‐English‐speaking witnesses and the impact of interpretation. 相似文献

Corrections of correlations for range restriction (i.e., selection) and unreliability are common in psychometric work. The current rule of thumb for determining the order in which to apply these corrections looks to the nature of the reliability estimate (i.e., restricted or unrestricted). While intuitive, this rule of thumb is untenable when the correction includes the variable upon which selection is made, as is generally the case. Using classical test theory, we show that it is the nature of the range restriction, not the nature of the available reliability coefficient, that determines the sequence for applying corrections for range restriction and unreliability.We would like to thank Malcolm James Ree for his encouragement and helpful comments as well as those of the editors, associate editor, and reviewers. 相似文献

Female agonism against males and male interventions in social transactions between the sexes are 2 explanations for the low rates of social engagement observed between male and female squirrel monkeys (Saimiri sciureus). These possibilities were evaluated by comparing the frequency, structure, and content of transactions between the sexes in 3 experimental social units: male-female pairs, single-male-multifemale groups, and multimale-multifemale groups. Affiliative transactions between the sexes occurred 3-5 times less often in multimale-multifemale groups than in male-female pairs and in single-male-multifemale groups. Intermale agonism in the multimale-multifemale groups often coincided with ongoing transactions between the sexes, whereas female agonism against males was rather uncommon in all social units. The results failed to support the female agonism hypothesis and indicate a need for more detailed studies of intermale social dynamics. 相似文献

The paper obtains a maximum likelihood criterion test for multisample sphericity. The test contains Mauchly's sphericity test as a special case.I would like to thank Professor R. E. Bargmann for his most valuable help. 相似文献

Successful consultation relies on the consultant's ability to conceptualize the operations of the total organization. An overview of the theoretical and practical applications of the construct “organizational effectiveness” (OE) is presented in relation to consultation. Barriers limiting earlier conceptualizations and applications of the construct are identified and discussed. A model of OE that melds open systems, organizational, and consultation theories is presented as a tool for guiding maximally beneficial consultation interventions. The implications of this model for consultation practice, advancing theory and research, and professional ethics are discussed. 相似文献

Organizational and validation researchers often work with data that has been subjected to selection on the predictor and attrition on the criterion. These researchers often use the data observed under these conditions to estimate either the predictor or criterion's restricted population means. We show that the restricted means due to direct or indirect selection are a function of the population means plus the selection ratios. Thus, any difference between selected mean groups reflects the population difference plus the selection ratio difference. When there is also attrition on the criterion, the estimation of group differences becomes even more complicated. The effect of selection and attrition induces measurement bias when estimating the restricted population mean of either the predictor or criterion. A sample mean observed under selection and attrition does not estimate either the population mean or the restricted population mean. We propose several procedures under normality that yield unbiased estimates of the mean. The procedures focus on correcting the effects of selection and attrition. Each procedure was evaluated with a Monte Carlo simulation to ascertain its strengths and weaknesses. Given appropriate sample size and conditions, we show that these procedures yield unbiased estimators of the restricted and unrestricted population means for both predictor and criterion. We also show how our findings have implications for replicating selected group differences. 相似文献

Child disaster mental health research has been largely limited by investigation of one disaster at a time and inconsistent methods across different studies. This study assessed 160 survivors of 3 disasters with structured diagnostic interviews, asking about the behavioral and emotional disaster reactions of their 266 children, ages 3–17. Most children had ≥1 postdisaster behavior change or disaster-related posttraumatic stress symptom. The children’s postdisaster behavioral and emotional problems were associated with parental postdisaster psychopathology. The results underscore the importance of asking disaster survivors about their children’s disaster reactions and considering parental disaster experiences and reactions in addressing their children’s reactions. 相似文献

Much research has been directed at the validity of fit indices in Path Analysis and Structural Equation Modeling (e.g., Browne, MacCallum, Kim, Andersen, &; Glaser, 2002; Heene, Hilbert, Draxler, Ziegler, &; Bühner, 2011; Hu &; Bentler, 1999; Marsh, Hau, &; Wen, 2004). Recent developments (e.g., Preacher, 2006; Roberts &; Pashler, 2000, 2002) have encouraged researchers to investigate other criteria for comparing models, including model complexity. What has not been investigated is the inherent ability of a particular data set to be fitted with a constrained set of randomly generated linear models, which we call Model Conditioned Data Elasticity (DE). In this article we show how DE can be compared with the problem of equivalent models and a more general problem of the “confoundability” of data/model combinations (see MacCallum, Wegener, Uchino, &; Fabrigar, 1993). Using the DE package in R, we show how DE can be assessed through automated computer searches. Finally, we discuss how DE fits within the controversy surrounding the use of fit statistics. 相似文献
