Zusammenfassung Es wurde an fünf Schulen ein hoher Zusammenhang zwischen Tüchtigkeit und Beliebtheit aufgezeigt, der mit steigendem Alter der Schüler allmählich absinkt.Relativ häufig sind die Tüchtigsten und die Beliebtesten in Schulklassen identisch; ein Zusammenhang mit dem Alter ist hierbei nicht nachzuweisen.Noch häufiger sind Beliebtheits- und Tüchtigkeitsstars identisch; in den unteren Klassen sind diese Identitäten signifikant zahlreicher als in den oberen Klassen.Die hohe Korrelation zwischen Tüchtigkeit und Beliebtheit kann nicht auf mangelnde Differenzierungsfähigkeit der Kinder zurückgeführt werden. Sie steht auch nicht im Zusammenhang mit dem Ranggradienten, der in allen Klassen relativ groß war.Wir sind Fräulein cand. phil. H. Heggemann für Erhebung und Auswertung eines Teils unseres Materials zu Dank verpflichtet6. 相似文献

David Herbert 《Islam & Christian-Muslim Relations》1993,4(2):257-267
This paper offers a Quaker perspective on the issues raised for British society by the Satanic Verses controversy. It is argued that the Quaker rejection of coercive power is founded upon the story of Jesus Christ. The origins of Quaker attitudes to free speech are located in seventeenth‐century Puritanism, arguing that Quakers share with Western secular defenders of free speech an internalization of the blasphemy taboo which issues in intolerance of anything held sacred. Furthermore, free speech rhetoric tends to ignore the power relations which sustain free speech in particular contexts. This is a neglect which, coupled with a secularized theory of race relations that ignores religious factors, renders its protagonists incapable of addressing anti‐Islamic prejudice, a phenomenon illustrated from press coverage of the controversy. The implications of this argument for British society and Quakers in particular are then considered. It is argued that an extension of legislation covering incitement to racial hatred to religion is the most appropriate legal response, but the greatest need is educational. Quakers and other Christian groups need to develop their own theological response to avoid passively replicating the dominant view in society. 相似文献

The many null distributions of person fit indices 总被引:1,自引:0,他引:1
This paper deals with the situation of an investigator who has collected the scores ofn persons to a set ofk dichotomous items, and wants to investigate whether the answers of all respondents are compatible with the one parameter logistic test model of Rasch. Contrary to the standard analysis of the Rasch model, where all persons are kept in the analysis and badly fittingitems may be removed, this paper studies the alternative model in which a small minority ofpersons has an answer strategy not described by the Rasch model. Such persons are called anomalous or aberrant. From the response vectors consisting ofk symbols each equal to 0 or 1, it is desired to classify each respondent as either anomalous or as conforming to the model. As this model is probabilistic, such a classification will possibly involve false positives and false negatives. Both for the Rasch model and for other item response models, the literature contains several proposals for a person fit index, which expresses for each individual the plausibility that his/her behavior follows the model. The present paper argues that such indices can only provide a satisfactory solution to the classification problem if their statistical distribution is known under the null hypothesis that all persons answer according to the model. This distribution, however, turns out to be rather different for different values of the person's latent trait value. This value will be called ability parameter, although our results are equally valid for Rasch scales measuring other attributes.As the true ability parameter is unknown, one can only use its estimate in order to obtain an estimated person fit value and an estimated null hypothesis distribution. The paper describes three specifications for the latter: assuming that the true ability equals its estimate, integrating across the ability distribution assumed for the population, and conditioning on the total score, which is in the Rasch model the sufficient statistic for the ability parameter.Classification rules for aberrance will be worked out for each of the three specifications. Depending on test length, item parameters and desired accuracy, they are based on the exact distribution, its Monte Carlo estimate and a new and promising approximation based on the moments of the person fit statistic. Results for the likelihood person fit statistic are given in detail, the methods could also be applied to other fit statistics. A comparison of the three specifications results in the recommendation to condition on the total score, as this avoids some problems of interpretation that affect the other two specifications.The authors express their gratitude to the reviewers and to many colleagues for comments on an earlier version. 相似文献

Two studies were designed to explore the role of performance factors as sources of the frequently noted higher male scores on visual-spatial ability tests. In the first study, the mental rotations test (MRT) was administered to male and female college students of equally high quantitative ability (based on SAT math scores). Although males had significantly more correct responses on the test than did females, their advantage was eliminated when the ratio of correct responses to items attempted was used as the dependent measure. In the second study, the same test was administered to new groups of male and female college students. In this sample, the males had significantly higher SAT math scores. The MRT was administered under standard, timed conditions and under untimed conditions. Both raw and ratio scores were calculated. With SAT math score as the covariate, analyses of covariance indicated that males demonstrated higher performance in the timed, raw-score condition but not in the untimed or in the ratio-score conditions. The theoretical and social policy implications of these studies are discussed. 相似文献

The current literature suggests that individuals who chronically abuse alcohol exhibit a wide variety of cognitive deficits
resulting from cerebral dysfunction that is either directly or indirectly related to their alcohol consumption history. Cognitive
deficits have been hypothesized as having implications for standard alcohol treatment efficacy as they may directly affect
cognitively impaired individuals’ abilities to utilize various treatment modalities. Although evidence is accumulating that
suggests this is actually the case, the majority of alcohol treatment programs neither directly consider the impact cognitive
deficits have on treatment efficacy nor do they employ cognitive rehabilitation treatment strategies to remediate identified
cognitive deficits. Few studies exist that investigate the remediability of neurobehavioral deficits or the efficacy of integrating
cognitive rehabilitation strategies into more traditional treatment programs. Empirical investigations conducted to date indicate
that some cognitive deficiencies secondary to alcoholism are amenable to cognitive rehabilitation and this remediation is
generalizable. Rigorous well-controlled treatment outcome investigations are needed in order to determine the efficacy of
cognitive rehabilitation techniques in naturalistic settings using ecological outcome measures. Also, emphasis should be placed
on integrating cognitive rehabilitation techniques with proven efficacy into traditional alcoholism treatment programs. 相似文献

The question, whether schooling exerts a substantial influence on the development of intelligence is an issue of ongoing discussion. In our study we (a) present a quasi-experimental design to separate schooling effects from effects of chronological age and (b) apply it to intelligence test data of (n = 578) 10-year-old children. The results show that there are considerable schooling effects on all tests, including the tests of fluid intelligence, and that schooling effects explain most all of the intellectual progress made during 1 year of life at that age, measured by the increase in the mean scores of the tests. 相似文献

An assumption of the generate/recognize model of direct and indirect memory is that the generation stage is identical on explicit and implicit tests. Two experiments were conducted to examine the generation stage by requiring subjects to write down every word-stem solution they could generate on either an implicit test, a cued-recall test, or a generate/recognize test. In Experiment 1, the subjects studied words and anagrams; target generation was not significantly different on the three tests. However, in Experiment 2, the subjects studied the target words with a context word, and saw either thesame ordifferent context with the test stem. Now the generation stages dissociated, such that the context manipulation had no significant effect on the implicit test, but on the cued-recall test, more targets were generated with the same context words than were generated with different context words. The results argue against the claim that dissociations between implicit and explicit tests are due only to the addition of recognition processes on the explicit test, because the generation processes themselves can be dissociated. 相似文献

The topic under examination is the idea of ‘supervenient dualism’, which Christopher Shields first put forward in his study of Aristotle's theory of psychology. Shields takes supervenient dualism to be a form of ‘substance supervenience’, in which an immaterial substance supervenes upon a material or physical substance. Shields, however, does not develop a convincing version of supervenient dualism because he fails to develop a convincing version of substance supervenience. A plausible version of substance supervenience can be developed in the light of Jaegwon Kim's idea of ‘multiple-domain supervenience’, although this version of substance supervenience is not able to provide the basis for an adequate formulation of supervenient dualism. The nature of this version of substance supervenience depends upon a relation of coordination between the substances, and there does not seem to be any relation of coordination that yields a form of substance supervenience that also counts as a form of supervenient dualism. 相似文献
