It is proposed that causal judgments about contingency information are derived from the proportion of confirmatory instances (pCI) that are evaluated as confirmatory for the causal candidate. In 6 experiments, pCI values were manipulated independently of objective contingencies assessed by the deltaP rule. Significant effects of the pCI manipulations were found in all cases, but causal judgments did not vary significantly with objective contingencies when pCI was held constant. The experiments used a variety of stimulus presentation procedures and different dependent measures. The power PC theory, a weighted version of the deltaP rule, the Rescorla-Wagner associative learning model (R. A. Rescorla & A. R Wagner, 1972), and the deltaD rule, which is the frequency-based version of the pCI rule, were unable to account for the significant effects of the pCI manipulations. These results are consistent with a general explanatory approach to causal judgment involving the evaluation of evidence and updating of beliefs with regard to causal hypotheses.  相似文献

Factor analysis is regularly used for analyzing survey data. Missing data, data with outliers and consequently nonnormal data are very common for data obtained through questionnaires. Based on covariance matrix estimates for such nonstandard samples, a unified approach for factor analysis is developed. By generalizing the approach of maximum likelihood under constraints, statistical properties of the estimates for factor loadings and error variances are obtained. A rescaled Bartlett-corrected statistic is proposed for evaluating the number of factors. Equivariance and invariance of parameter estimates and their standard errors for canonical, varimax, and normalized varimax rotations are discussed. Numerical results illustrate the sensitivity of classical methods and advantages of the proposed procedures.This project was supported by a University of North Texas Faculty Research Grant, Grant #R49/CCR610528 for Disease Control and Prevention from the National Center for Injury Prevention and Control, and Grant DA01070 from the National Institute on Drug Abuse.

This paper focuses on Michael Balint's special application of psychoanalysis, originally conceived as a training of doctors. Then the attempt is made to discover indirectly, since Balint never described his method in context, what he thought mattered in terms of method. Besides Balint's own contributions, those of his own staff are also consulted as well as the cultural background of the Tavistock Clinic and the Tavistock Institute. Then the further developments of the Balint method in the German-speaking world are presented. At the center are the special features of the method: (a) the atmosphere, (b) the narrator's contribution, (c) listening and reactions of the members of the group, (d) the unconscious enactments in transference and countertransference and the mirror-phenomena, respectively. Furthermore, the respective central points of reference are discussed from the viewpoint of communication science: (a) case, (b) group, and (c) institution. In conclusion and based on these foundations, the characteristics of the application of the Balint method in the form of a particular profession-related supervision are presented.  相似文献

This article challenges Block's ‘overflow argument’ for the conclusion that phenomenal consciousness and access‐consciousness are distinct. It shows that the data can be explained just as well (or better) in terms of a distinction between contents that are made globally accessible through bottom–up sensory stimulation and those that are sustained and made available in working memory through top‐down attention.  相似文献

This study examined the effect of anticipated food deprivation on intake in restrained and unrestrained eaters. Participants were randomly assigned to a diet condition, in which they expected to diet for a week, or to a control (no-diet) condition. Immediately after being assigned to a condition, participants completed a taste-rating task in which food consumption was measured. Restrained eaters in the diet condition consumed significantly more food than did restrained eaters in the no-diet condition or unrestrained eaters in either condition. Unrestrained eaters consumed the same amount regardless of condition. These results confirm that merely planning to go on a diet can trigger overeating in restrained eaters, reflecting the dynamic connection between dieting and overeating.  相似文献

Despite the fact that developmental coordination disorder (DCD) is characterised by a deficit in the ability to learn or automate motor skills, few studies have examined motor learning over repeated trials. In this study we examined procedural learning in a group of 10 children with DCD (aged 8-12 years) and age-matched controls without DCD. The learning task was modelled on that of Nissen and Bullemer. Children performed a serial reaction time (SRT) task in which they were required to learn a spatial sequence that repeated itself every 10 trials. Children were not aware of the repetition. Spatial targets were four (horizontal) locations presented on a computer monitor. Children responded using four response keys with the same horizontal mapping as the stimulus. They were tested over five blocks of 100 trials each. The first four blocks presented the same repeating sequence, while the fifth block was randomised. Procedural learning was indexed by the slope of the regression of RT on blocks 1-4. Results showed that most children displayed strong procedural learning of the sequence, despite having no explicit knowledge about it. Overall, there was no group difference in the magnitude of learning over blocks of trials - most children performed within the normal range. Procedural learning for simple sequential movements appears to be intact in children with DCD. This suggests that cortico-striatal circuits that are strongly implicated in the sequencing of simple movements appear to be function normally in DCD.  相似文献

In this article I address some topical themes from the ongoing discussion on contemporary religious change in the West and how it poses conceptual challenges to the study of religion. The academic discussion on religious change is vast and my observations are, of course, by necessity limited to my particular interest and argument in this article. On the one hand, I draw on some of the literature that has evolved within and around the concept of postsecularity and, on the other, on more general literature on contemporary religious change. Based on some selected observations, I underline the need to critically rethink how we conceptualize both religion and religious subjects. In my view, current research fosters a greater attentiveness of complexity with regard to religion, but simultaneously it requires us to take seriously a dialogical notion of religious subjects that provides a conceptual account of a subject constituted by being located within and emerging through ongoing social process. This dialogical notion provides a better tool for how current social and cultural reconfigurations of religion are simultaneously played out as a diversity of identities that challenge received categories, such as the religious and the secular.  相似文献

The purpose of this study is to examine the relationship between sanctification of life and health. Sanctification is defined as a process through which aspects of life are perceived as having divine character and significance. A latent variable model was created to test the following hypotheses that link sanctification with health: (1) people who attend worship services more often are more likely to develop a sanctified view of life; (2) individuals who develop a sanctified view of life are likely to be more compassionate, (3) people who are more compassionate will provide more emotional support to others, (4) providing more support to others will be associated with a greater sense of meaning in life, and (5) people who have derived a deeper sense of meaning in life will enjoy better health. Data from a new cross-sectional nationwide survey (N?=?2932) provide support for each of these hypotheses.  相似文献
