Comparisons of the mean IQs of Northern and Southern blacks have consistently shown a 7–12 point difference favoring the former group. Explanations of this difference have been highly polarized. Hereditarians have generally favored an hypothesis of selective migration; environmentalists have tended to ascribe the difference to such environmental causes as education, discrimination and cultural deprivation. Two studies (Klineberg, 1935; Lee, 1951) have been interpreted by many commentators as decisively vindicating the environmentalist position. In this paper this interpretation is questioned and certain neglected features of Lee's (1951) data are construed as providing strong evidence for selective migration. 相似文献

Multilevel structural equation models are increasingly applied in psychological research. With increasing model complexity, estimation becomes computationally demanding, and small sample sizes pose further challenges on estimation methods relying on asymptotic theory. Recent developments of Bayesian estimation techniques may help to overcome the shortcomings of classical estimation techniques. The use of potentially inaccurate prior information may, however, have detrimental effects, especially in small samples. The present Monte Carlo simulation study compares the statistical performance of classical estimation techniques with Bayesian estimation using different prior specifications for a two-level SEM with either continuous or ordinal indicators. Using two software programs (Mplus and Stan), differential effects of between- and within-level sample sizes on estimation accuracy were investigated. Moreover, it was tested to which extent inaccurate priors may have detrimental effects on parameter estimates in categorical indicator models. For continuous indicators, Bayesian estimation did not show performance advantages over ML. For categorical indicators, Bayesian estimation outperformed WLSMV solely in case of strongly informative accurate priors. Weakly informative inaccurate priors did not deteriorate performance of the Bayesian approach, while strong informative inaccurate priors led to severely biased estimates even with large sample sizes. With diffuse priors, Stan yielded better results than Mplus in terms of parameter estimates. 相似文献

When evaluating the arguer instead of the argument, we soon find ourselves confronted with a puzzling situation: what seems to be a virtue in one argumentative situation could very well be called a vice in another. This paper will present the idea that there are in fact two sets of virtues an arguer has to master—and with them four sometimes very different roles. 相似文献

The age benefit found in many naturalistic prospective memory (PM) tasks has been taken as evidence that PM performance in real life may be spared from aging. However, this conclusion lacks empirical confirmation. Hence, the aim of the present study was to examine possible age differences in the content of everyday PM intentions and their performance. Everyday PM was assessed in young and older adults using a diary approach. Results confirmed a general age benefit for real-life PM tasks. Importantly, this finding was qualified by revealing that the benefit only held true for specific types of intentions such as health and social intentions. Further, moderation analyses showed that the relationships between cognitive functioning and everyday PM were different for young and older adults. While better inhibition, short-term and long-term memory were related with successful PM performance in the young, this was not the case in the older adults. The present findings suggest that the age benefit found in naturalistic experimenter-given tasks extends to real-life PM performance, but may differ depending on the type of intention. Furthermore, cognitive functioning predicts performance in the young, but not in the older adults. 相似文献

This paper shows why Kant's critique of empirical psychology should not be read as a scathing criticism of quantitative scientific psychology, but has valuable lessons to teach in support of it. By analysing Kant's alleged objections in the light of his critical theory of cognition, it provides a fresh look at the problem of quantifying first‐person experiences, such as emotions and sense‐perceptions. An in‐depth discussion of applying the mathematical principles, which are defined in the Critique of Pure Reason as the constitutive conditions for mathematical‐numerical experience in general, to inner sense will demonstrate why it is in principle possible to justify a quantitative structure of psychological judgments on the grounds of Kant's critical thinking. In conclusion, it will propose how Kant's critique could be used in a constructive way to develop first steps towards a transcendental foundation of psychological knowledge. 相似文献

Despite the amount of privatizations around the world in recent decades, only limited research attention has been paid to how privatization affects the employees. The effects are likely to vary depending on the individual's position in the organization. The aim of this study was to investigate how employees' work‐related attitudes and strain changed after privatization of a Swedish acute care hospital, and to analyze whether the effects of privatization differed between employees at various hierarchic levels. Questionnaire data collected at a hospital 1 year before and 2 years after privatization, as well as at a hospital which remained a public administration unit, suggest only limited effects of privatization on a general level, but that employees at various hierarchic levels may be affected differently. While employees at a high level (physicians) and low level (assistant nurses) reported only marginal differences over time in work attitudes and strain, also in comparison with their colleagues at the comparison hospital, work attitudes of employees at the intermediate level (registered nurses) decreased after privatization. These results emphasize the importance of taking hierarchic level into account when a privatization is implemented and analyzed. 相似文献

Examined the concurrent validity of the attention-deficit/hyperactivity disorder (ADHD) module of the Anxiety Disorders Interview
Schedule for DSM-IV, Child and Parent versions (ADIS-C/P). One hundred eighty-four clinic-referred children were categorized into three ADIS-generated
groups: No diagnosis of ADHD (No ADHD; n = 63), parent-only diagnosis of ADHD (Parent Only; n = 81), and parent plus child diagnosis of ADHD (Parent + Child; n = 40). The groups were compared on demographics, comorbid diagnoses, parent and child-report measures, and a computerized
test of attention. Results support the concurrent validity of the ADIS ADHD module and highlight the positive relationship
between internalizing symptomatology and parent-child agreement on ADHD diagnoses. The clinical implication of this study
is that parent-child agreement on ADHD may serve as a marker of internalizing symptomatology. Future research on child self-perceptions
is suggested in developing treatments for this internalizing ADHD group.

We examined the effect of distributed practice on the mathematical performance of third and seventh graders (N = 213) in school. Students first received an introduction to a mathematical topic, derived from their curriculum. Thereafter, they practiced in one of two conditions. In the massed condition, they worked on three practice sets in 1 day. In the distributed condition, they worked on one practice set per day for 3 consecutive days. Bayesian analyses of the performance in two follow‐up tests 1 and 6 weeks after the last practice set revealed a positive effect of distributed practice as compared with massed practice in Grade 7. In Grade 3, a positive effect of distributed practice was supported by the data only in the test 1 week after the last practice set. The results suggest that distributed practice is a powerful learning tool for both elementary and secondary school students in the classroom. 相似文献
