Nineteen different anthropometric measures were obtained on all members of each of two racial groups. A procedure was developed and applied to the data to give maximum differentiation between the groups. The method is applicable wherever we have a large number of independent variables and a dependent variable. In such cases, the conventional methods for determining multiple regression constants are very laborious. An iteration method is presented which is more rapid than any with which the writers are familiar. The method selects in sequence those variables which together yield the largest multiple correlation with the criterion. At each step in the procedure, rapid estimates of the regression weights and the multiple correlation at that point are available. 相似文献

The Creative Product Semantic Scale has been used to judge tangible creative products such as crafts, and intangibles such as the ideas produced by problem solving groups. In this study it was used to judge the creativity of 15 print advertisements, using samples representing college students, advertising professionals, and the general public. The study explored the differences and similarities of responses. There were no significant differences in the judgments of the three groups regarding the originality and logic of the ads. With regard to how well crafted or well executed the ads were, however, the judgments of advertising professionals differed from those of students and the public. 相似文献

Since colonial times, the United States has been a majority Protestant nation. But the proportion Protestant in the population has been falling for over a decade, and Protestants are poised to lose their majority status. This decline results from a decline in the intergenerational retention rate for Protestants and from the attrition of Protestants among the youngest cohorts. Shifts in immigration also contribute to the Protestant decline. We also consider the role of an increasing share of people identifying as generic Christians and as inter- or nondenominational. 相似文献

The Kimberley Indigenous Cognitive Assessment (KICA) was initially developed and validated as a culturally appropriate dementia screening tool for older Indigenous people living in the Kimberley. This paper describes the re‐evaluation of the psychometric properties of the cognitive section (KICA‐Cog) of this tool in two different populations, including a Northern Territory sample, and a larger population‐based cohort from the Kimberley. In both populations, participants were evaluated on the KICA‐Cog tool, and independently assessed by expert clinical raters blinded to the KICA scores, to determine validity and reliability of dementia diagnosis for both groups. Community consultation, feedback and education were integral parts of the research. for the Northern Territory sample, 52 participants were selected primarily through health services. Sensitivity was 82.4% and specificity was 87.5% for diagnosis of dementia, with area under the curve (AUC) of .95, based on a cut‐off score of 31/32 of a possible 39. for the Kimberley sample, 363 participants from multiple communities formed part of a prevalence study of dementia. Sensitivity was 93.3% and specificity was 98.4% for a cut‐off score of 33/34, with AUC = .98 (95% confidence interval: 0.97–0.99). There was no education bias found. The KICA‐Cog appears to be most reliable at a cut‐off of 33/39. 相似文献

In this paper I draw attention to a peculiar epistemic feature exhibited by certain deductively valid inferences. Certain deductively valid inferences are unable to enhance the reliability of one’s belief that the conclusion is true—in a sense that will be fully explained. As I shall show, this feature is demonstrably present in certain philosophically significant inferences—such as GE Moore’s notorious ‘proof’ of the existence of the external world. I suggest that this peculiar epistemic feature might be correlated with the much discussed phenomenon that Crispin Wright and Martin Davies have called ‘transmission failure’—the apparent failure, on the part of some deductively valid inferences to transmit one’s justification for believing the premises. 相似文献

Incubation has long been proposed as a mechanism in creative problem solving (Wallas, 1926). A new trial‐by‐trial method for observing incubation effects was used to compare the forgetting fixation hypothesis with the conscious work hypothesis. Two experiments examined the effects of incubation on initially unsolved Remote Associates Test (RAT) problems. Following exposure to misleading clues designed to induce initial fixation on RAT problems, versus no clues, participants were retested on problems either immediately after their first attempt (no‐incubation), or after a 40‐second incubation period. Resolution of initially unsolved RAT problems (fixated versus non‐fixated) was examined as a function of complete interruption (Experiment 1) or partial distraction (Experiment 2). An incubation effect, that is, better resolution of initially unsolved problems retested after a delay rather than retesting immediately, was seen only in Experiment 1, in which unsolved problems were completely removed from sight. Furthermore, an incubation effect was found only for initially fixated problems, and not for problems that were not accompanied by misleading clues. The results are consistent with the forgetting fixation hypothesis (Smith & Blankenship, 1989), which states that putting unsolved problems completely out of mind allows initial fixation to dissipate, and the results indicate that the opportunity for some conscious work during incubation periods may not be optimal for resolving fixation. 相似文献

Composite materialism, as I will understand it, is the view that human persons are composite material objects. This paper develops and investigates an argument, The Vague Singulars Argument, for the falsity of composite materialism. We shall see that cogent or not, the Vague Singulars Argument has philosophically significant ramifications. 相似文献
