The Cigarette Purchase Task is a behavioral economic assessment tool designed to measure the relative reinforcing efficacy of cigarette smoking across different prices. An exponential demand equation has become a standard model for analyzing purchase task data, but its utility is compromised by its inability to accommodate values of zero consumption. We propose a two‐part mixed effects model that keeps the same exponential demand equation for modeling nonzero consumption values, while providing a logistic regression for the binary outcome of zero versus nonzero consumption. Therefore, the proposed model can accommodate zero consumption values and retain the features of the exponential demand equation at the same time. As a byproduct, the logistic regression component of the proposed model provides a new demand index, the “derived breakpoint”, for the price above which a subject is more likely to be abstinent than to be smoking. We apply the proposed model to data collected at baseline from college students (N = 1,217) enrolled in a randomized clinical trial utilizing financial incentives to motivate tobacco cessation. Monte Carlo simulations showed that the proposed model provides better fits than an existing model. We note that the proposed methodology is applicable to other purchase task data, for example, drugs of abuse.  相似文献

The purpose of this study was to explore how environmental factors (family environment and school education) and individual characteristics (personality, creative attitudes, and divergent thinking) collectively affect creative achievement of American and Chinese college students. Data were collected from 378 college students in the United States (N = 193) and China (N = 185). Results showed that the US sample had significantly higher means in home resources, high-school education, Conscientiousness, creative achievement, and all four dimensions of the Abbreviated Torrance Test for Adults (ATTA) than the China sample. In contrast, the China sample scored significantly higher in understanding the importance of creativity. Results indicated creative attitudes and divergent thinking sequentially mediated the effects of parental values on creative achievement for the US sample, whereas Openness mediated the effect of high-school education on creative achievement for the China sample. For both samples, creative attitudes mediated the effect of Openness on divergent thinking. The results suggested cultural differences in the effects of environmental factors on creativity, yet more similar findings in the effects of individual characteristics on creativity between the two samples. The results and implications are discussed.  相似文献

Family theory has refocused attention from deficits to family strengths, and interest in family resilience across cultures has become more widespread. However, few instruments were designed for quantitative research on family resilience. The Family Resilience Assessment Scale (FRAS) was designed to measure family resilience and has been administered in Western populations. The aim of this study was to adapt the FRAS for use with Chinese populations and examine its psychometric properties. The study was conducted using a sample of 991 university students in China (62.9 % female, mean age 20, SD = 1.12). First, the scale was translated and modified into Chinese, and good language equivalency was found. Next, confirmatory factor analysis was used to identify the best-fitting model. Results showed that the 3-factor model consisting of 32 items was an adequate fit. The goodness-of-fit index values for the model were χ 2/df = 5.97, CFI = .84, RMSEA = .08, SRMR = .05. Total scale reliability was α = .95. According to these values it can be said that the modified Chinese version of the FRAS was adapted successfully to the Chinese culture. Moreover, researchers and clinicians can use this instrument to assess family strengths when working with individuals in families experiencing adversity.  相似文献

This article is based on the author's extensive research on the missionaries to Tibet from the Disciples of Christ (Christian Church) USA, and discusses various missionary efforts to transmit scientific and practical knowledge such as medicine, building, and agriculture in Eastern Tibet from 1904–1919. It shows that American missionaries played a prominent and distinctive role in the dissemination of scientific and practical knowledge as a result of their hard work and wisdom. In this sense, they made an important contribution to the development of Tibetan society and the modernization movement in early twentieth‐century Eastern Tibet.  相似文献

This article argues against the non-cognitivist theory of vision that has been formulated in the work of Nico Orlandi. It shows that, if we understand ‘representation’ in the way Orlandi recommends, then the visual system’s response to abstract regularities must involve the formation of representations. Recent experiments show that those representations must be used by the visual system in the production of visual experiences. Their effects cannot be explained by taking them to be non-visual effects involving attention or memory. This contradicts Orlandi’s version of the non-cognitivist hypothesis, but does so while vindicating her methodological position.  相似文献

心理测验中个人拟合研究的回顾与展望   总被引:1,自引:0,他引:1  
个人拟合研究是对心理测验中偏差行为鉴别的一种新方法,它以Guttman理想模型、项目反应理论和非参数项目反应理论为基础。传统个人拟合指标是对宽泛偏差行为的检验,当前个人拟合研究更具体、更形象,针对于某种偏差行为的专门性指标和图形与回归分析受到了越来越多的关注。但无论哪种个人拟合方法都会受到各种无关因素的影响,如何克服这些影响,提高个人拟合方法的实际应用价值将成为个人拟合研究的主要方向  相似文献

天台宗性具善恶说,具有较为明显的泛恶倾向,且处处脱不了审丑思维。自梁、陈入隋,智顗弘法数十载,其中贯穿了对丑类恶物的审度和涵化。不光恶为丑因、恶中见丑、审丑观恶,善和美也以各种通道与丑相融互格,共同呈现出多维流动、浑化自洽的球体架构。这种圆融宽厚的丑学,反映了“末法时期”的悲悯思维,也昭示着一个恢宏多采时代的到来。  相似文献

本文采用字表方式,从高低词频和新旧效应角度,探讨内隐和外显测验中定向遗忘效应的存在性及其机制问题。结果发现:(1)低频词在两种测验中都存在定向遗忘效应,而高频词仅存在于外显测验中。(2)两种测验中都存在指示记住的新旧效应,而外显测验中不存在指示忘记的新旧效应。由此推断,测验间在没有"意识和无意识"相互污染的理想情况下,只有外显测验可获得定向遗忘效应;定向遗忘的机制可能是选择性编码机制。  相似文献
