The perceptual fluency/attributional model of the mere-exposure effect proposed by R. F. Bornstein and P. D'Agostino (1992) predicts that when recognition of a previously presented stimulus is above chance, feelings of fluency associated with that stimulus are discounted and thus the amount of fluency (mis)attributed to liking is reduced. This correction process results in smaller mere-exposure effects for supraliminal stimuli than for “subliminal” stimuli because when recognition is below chance participants are unaware of the source of fluency and they do not engage in correction. We tested this prediction in three experiments by presenting photographs of faces (Experiments 1 and 2) and polygons (Experiment 3) at varying exposure frequencies for 40 ms and 400 ms durations. Contrary to the prediction of the model, a significant mere-exposure effect was only found when recognition performance was at its highest level. Furthermore, across the three experiments liking and recognition were positively correlated.  相似文献

Despite the growth of youth mentoring programs in recent years, key questions remain regarding the relative importance of making matches on the basis of shared racial background. Both sides of the argument regarding racial matching are presented, followed by a comparison of the effects of same‐ vs. cross‐race matches involving minority youth (N= 476). Minority adolescents were less likely to report initiating alcohol when placed in cross‐race matches. In addition, minority boys in same‐race matches reported smaller decrements in scholastic competence and self‐worth than did minority boys in cross‐race matches. Minority girls in same‐race matches reported smaller decrements in school value and self‐worth than did minority girls in cross‐race matches. Youth, parent, and caseworker impressions of the 2 relationship types largely converged, but the few impressions that differed tended to favor cross‐race matches. The methodological limitations and implications of this study are discussed.  相似文献

Causation as Simultaneous and Continuous   总被引:3,自引:0,他引:3  
We propose that all actual causes are simultaneous with their direct effects, as illustrated by both everyday examples and the laws of physics. We contrast this view with the sequential conception of causation, according to which causes must occur prior to their effects. The key difference between the two views of causation lies in differing assumptions about the mathematical structure of time.  相似文献

We examined the relationship between executive functions and both factual and conceptual learning of science, specifically chemistry, in early adolescence. Sixty‐three pupils in their second year of secondary school (aged 12–13 years) participated. Pupils completed tasks of working memory (Spatial Working Memory), inhibition (Stop‐Signal), attention set‐shifting (ID/ED), and planning (Stockings of Cambridge), from the CANTAB. They also participated in a chemistry teaching session, practical, and assessment on the topic of acids and alkalis designed specifically for this study. Executive function data were related to (1) the chemistry assessment which included aspects of factual and conceptual learning and (2) a recent school science exam. Correlational analyses between executive functions and both the chemistry assessment and science grades revealed that science achievements were significantly correlated with working memory. Linear regression analysis revealed that visuospatial working memory ability was predictive of chemistry performance. Interestingly, this relationship was observed solely in relation to the conceptual learning condition of the assessment highlighting the role of executive functions in understanding and applying knowledge about what is learned within science teaching.  相似文献

Islamic banking is based on moral foundations that make it distinct from conventional banking. Some argue that because of its foundation in Islam, Islamic banking may represent a more morally appealing alternative. Yet, evidence shows that this is not the case. Indeed, the current practice of Islamic banking has not been able to achieve its goals which are based on Islam's moral values: to enhance justice, equitability, and social well‐being. This essay examines the extent to which Islamic banking is ethical and concludes that the practice of the industry does not seem to be de facto ethical from the Islamic perspective of ethical values. It only consists in trading the same instruments of conventional banks without genuinely enforcing Islam's ethical vision. The practice of Islamic banking misrepresents Islam and does not contribute to solving social problems. The interaction between maqasid al‐shari?a (objectives of Islamic law) and qiyās (deductive analogy) provides a supplementary tool for interpreting the failure of the prior in terms of the practical misuse of the latter by Islamic banks. This essay provides an interpretive approach to the current debate about why Islamic banking has failed and suggests ways to move cautiously in the future.  相似文献

A coefficient of interrelationship between overlapping groups that avoids indeterminacies inherent in the construction of fourfold tables for such purposes and, at the same time, is relatively insensitive to the absolute magnitude of marginal totals of fourfold tables, is developed. Under assumptions that are consistent with the objectives of organizational analysis, this coefficient is shown to be equivalent to a product-moment correlation coefficient. The advantages and limitations of this coefficient are pointed out. A numerical example giving computational procedures is presented.This measure was developed in connection with a study made by Dorothy C. Adkins (1). Her influence in the development was felt in many ways. The article was prepared while the author was employed at The University of North Carolina.  相似文献
