Review and metaanalyses of published validation studies for the years 1964-1982 of Journal of Applied Psychology and Personnel Psychology were undertaken to examine the effect of (1) research design; (2) criterion used; (3) type of selection instrument used; (4) occupational group studies; and (5) predictor-criterion combination on the level of observed validity coefficients. Results indicate that concurrent validation designs produce validity coefficients roughly equivalent to those obtained in predictive validation designs and that both of these designs produce higher validity coefficients than does a predictive design which includes use of the selection instrument. Of the criteria examined, performance rating criteria generally produced lower validity coefficients than did the use of other more "objective" criteria. In comparing the validities of various types of predictors, it was found cognitive ability tests were not superior to other predictors such as assessment centers, work samples, and supervisory/peer evaluations as has been found in previous metaanalytic work. Personality measures were clearly less valid. Compared to previous validity generalization work, much unexplained variance in validity coefficients remained after corrections for differences in sample size. Finally, the studies reviewed were deficient for our purposes with respect to the data reported. Selection ratios, standard deviations, reliabilities, predictor and criterion intercorrelations were rarely and inconsistently reported. There are also many predictor-criterion relationships for which very few validation efforts have been undertaken. 相似文献

This study was designed to determine possible differences in the cognitive, perceptual, and personal-social development of prematurely and maturely born 3-yr.-olds which might foreshadow later learning problems. The subjects were 40 prematurely born graduates of a neonatal intensive care unit (birth weight less than 2,500 gm, less than 37 wk. gestation) matched on the pair-level with full-term controls on sex, race, post-conceptual age, and socioeconomic background. All subjects were singletons and parity was matched at the group level. No differences were found between the groups on tests of higher mental processes including the General Cognitive, Verbal, Quantitative, and Memory Scales of the McCarthy Scales of Children's Abilities, and researcher-devised measures of problem-solving competence. No differences in parental reports of personal-social development were noted. Prematures did not perform as well as controls on perceptual performance tasks, and this difference was interpreted as reflecting relatively impaired visual-motor coordination. 相似文献

Redundancy analysis (also called principal components analysis of instrumental variables) is a technique for two sets of variables, one set being dependent of the other. Its aim is maximization of the explained variance of the dependent variables by a linear combination of the explanatory variables. The technique is generalized to qualitative variables; it then gives implicitly a simultaneous optimal scaling of the dependent, qualitative variables. Examples are taken from the Dutch Life Situation Survey 1977, using Satisfaction with Life and Happiness as dependent variables. The analysis leads to one well-being scale, defined by the explanatory variables Marital status, Schooling, Income and Activity.The views expressed in this paper are those of the author and do not necessarily reflect the policies of the Netherlands Central Bureau of Statistics. 相似文献

The work of W.E.B. Du Bois highlights the significance of Christian religion in Black American life. According to Du Bois, the Black Church serves as a site of self-formation and affirmation, and the White Church as a source of racist beliefs and justifications for inequality. In this paper, we expand Du Bois’ inquiry about the influence of religion with a study of Black Americans who belong to a predominantly White religion. For those whose religious experience is almost wholly within the “white world,” what role does religion play in their lives? We analyze a set of 52 public accounts by Black Americans discussing their experiences as members of the Church of Jesus Christ of Latter-day Saints (LDS). We find that for many Black LDS, membership in the LDS Church is characterized by contrast and contradiction, yielding spiritual conviction, joy, and meaningful communion on one hand, and racism and isolation on the other. We also find that Black LDS respond to these contradictions in a variety of ways. We classify these agentic responses into five types and examine the sociological significance of the observed variation. We conclude with a discussion of implications for scholarship on race and religion. 相似文献

COVID-19 vaccine concerns remain high among Americans. Although recent studies have investigated the sociodemographic disparities in vaccine concerns, less attention has been given to reasons for vaccine skepticism and psychosocial factors that may explain it. The current study examined specific types of vaccine concerns among a diverse sample of college students (N = 1985) living in New York City. Participants who identified as Black, younger, with later immigrant generational status, and those with more conservative political leanings reported more vaccine concerns. Concerns regarding vaccine side effects were the most frequently reported source of concern. Reason for getting vaccinated, personal experiences with COVID, and COVID stress was also associated with vaccine concerns. Study results emphasize the importance of sociodemographic factors and COVID knowledge and stress in examining and addressing vaccine concerns. 相似文献

The electromyogram (EMG) recorded with surface electrodes was examined using a triggered oscilloscope technique. When all but the high-amplitude waveforms in a given segment of activity were excluded from analysis, it was found that the duration of the remaining waveforms was specific to the muscle that produced them. That is, waveforms of a given duration were recorded whenever conventional indices-observable contraction, joint movement. needle recordings-showed activity in a specific muscle. This led to the suggestion that waveform duration might be used to validate the surface EMG. The suggestion. which is limited by the need to control posture and electrode placement, both of which may influence waveform duration, was illustrated in application to psychological research. 相似文献

Drinking was studied in rats pressing a bar on a second-order schedule in which every third completion of a 1-min fixed interval was followed by food presentation. A brief flash of light signaled the completion of each fixed-interval component. The rats drank not only after the food presentations but also after presentations of the light flash alone. A high rate of steady drinking followed intervals terminated by a food presentation. Drinking that followed intervals terminated by a light flash alone was of comparable rate, but characteristically interrupted by bar pressing. When 250-mg food pellets were used instead of 45-mg pellets, both drinking and bar-pressing rates increased substantially. 相似文献
