Many traditional conjoint representations of binary preferences are additively decomposable, or additive for short. An important generalization arises under rank-dependence, when additivity is restricted to cones with a fixed ranking of components from best to worst (comonotonicity), leading to configural weighting, rank-dependent utility, and rank- and sign-dependent utility (prospect theory). This paper provides a general result showing how additive representations on an arbitrary collection of comonotonic cones can be combined into one overall representation that applies to the union of all cones considered. The result is applied to a new paradigm for decision under uncertainty developed by Duncan Luce and others, which allows for violations of basic rationality properties such as the coalescing of events and other framing conditions. Through our result, a complete preference foundation of a number of new models by Luce and others can be obtained. We also show how additive representations on different full product sets can be combined into a representation on the union of these different product sets. 相似文献

The National Board for Certified Counselors describes cybercounseling as the provision of some aspects of counseling through technology, via such applications as e‐mail, Web‐based information access, course registration, academic advising, and career guidance. The authors explore the characteristics of cybercounseling, describe its current use in the United States and South Korea, explore its advantages and disadvantages, and consider issues and concerns for college counselors. 相似文献

The present study examined the effect of spatial working memory load on the attentional cuing effect. It is well-known that spatial working memory and spatial attention functionally overlap or share a common resource. Given this functional overlapping, it is possible that spatial working memory would also interact with the attentional cuing effect. Considering the distinction between channel selection and channel enhancement by attention (Prinzmetal, McCool, & Park, 2005), we expected that the interaction between spatial working memory and the cuing effect would differ with attentional processing type. Two experiments conducted with the spatial cuing paradigm showed that the magnitude of the cuing effect as measured by reaction time, reflecting channel selection, was uninfluenced by spatial working memory load. In contrast, spatial working memory load reduced the cuing effect as measured by accuracy, reflecting channel enhancement. These results suggest that spatial working memory load impairs signal enhancement by attention and does not influence attentional orienting per se. The interaction between spatial working memory and visual perception is also discussed. 相似文献

We examined the influence of extrapersonal associations (Olson & Fazio, 2004)—associations that neither form the basis of the attitude nor become activated automatically in response to the object—on the Implicit Association Test (Greenwald, McGhee, & Schwartz, 1998) by experimentally creating both attitudes and extrapersonal associations. The results revealed that participants who were given extrapersonal information that was inconsistent with their own attitudes were affected by this information when they later performed an IAT. They exhibited significantly reduced IAT scores compared to participants who were provided attitude-consistent extrapersonal information. This attenuation of the IAT effect occurred despite the fact that participants rated the source of the attitude-inconsistent extrapersonal information as irrational and foolish. On the other hand, the extrapersonal associations did not influence a subliminal priming measure in Experiment 1, nor a personalized version of the IAT (Olson & Fazio, 2004) in Experiment 2. These measures proved sensitive to the attitude, regardless of the congruency of the extrapersonal information. 相似文献

To examine whether cultural differences exist in defining family, friend, relative, colleague and neighbour, non-student samples were drawn from Canada, China and India. The data generated several unexpected findings. (i) The means of the relationship definitions between the Chinese and Canadians were not significantly different. The means between the Chinese and Indians were significantly different. The means between the Canadians and Indians were significantly different. (ii) Females defined their relationships more interdependently than males in the Indian and Canadian samples but not in the Chinese sample. (iii) Definitions were target specific and the order of closeness differed from group to group. (iv) In the Indian and Chinese samples, participants' age was negatively correlated with closeness in defining friends, indicating that a person's perceived closeness with friends changes over the life span. Results of past research using student samples need to be interpreted with caution. 相似文献

运用实验的方法,对371名小学生创造性科学问题提出能力的发展进行了研究。结果表明:(1)小学生创造性科学问题提出能力整体呈上升趋势;(2)男女生的创造性科学问题提出能力发展趋势基本相同,男生整体上要略高于女生,差异不显著;(3)小学生创造性科学问题提出能力的学校类型差异主要表现在发展趋势上,城市小学二到三年级停滞不前,乡村小学则迅速发展,之后发展趋势相同;(4)三到四年级是小学生创造性科学问题提出能力发展的“关键期”。 相似文献

使用ERP技术考察了言语产生过程中语音和语义的激活情况。图片上有3种条件的干扰词,分别与目标图片名称形成3种关系:语义相关,语音相同,语义、语音、字形都不相关。结果显示,当被试执行延迟命名任务(实验1)时,与目标图片名称语义相关和控制条件的波形比语音相关的波形更趋于负向。说明在图片命名过程中语音有明显的促进作用。当要求被试对上述图片进行延迟语义判断任务(实验2)时,与目标图片名称语义相关、语音相关及控制条件的波形之间无明显差异。说明在语义提取过程中没有语音的促进作用。综合实验1和实验2,本研究的结果更倾向于支持独立两阶段模型。 相似文献

Changes in facial blood flow were investigated during an introductory conversation, delivering a speech, and listening to the speech afterwards in 16 people with a fear of blushing and 16 controls. It was hypothesized that fear of blushing would be associated with high ratings of self-reported blushing intensity and embarrassment during the tasks, and with persistence of the blushing reaction between tasks. Embarrassment and self-reported blushing intensity were greater in the fear-of-blushing group than in controls throughout the experiment. Increases in facial blood flow were similar in the two groups during each of the tasks. However, blushing dissipated more slowly after each task in the fear-of-blushing group than in controls, resulting in an incremental increase in facial blood flow over the course of the experiment. The slow recovery after an episode of blushing might result in physiological or social cues that help to maintain a fear of blushing. 相似文献

Nonnormality and divergence in posttreatment alcohol use: reexamining the Project MATCH data "another way." 总被引:1,自引:0,他引:1

Alcohol lapses are the modal outcome following treatment for alcohol use disorders, yet many alcohol researchers have encountered limited success in the prediction and prevention of relapse. One hypothesis is that lapses are unpredictable, but another possibility is the complexity of the relapse process is not captured by traditional statistical methods. Data from Project Matching Alcohol Treatments to Client Heterogeneity (Project MATCH), a multisite alcohol treatment study, were reanalyzed with 2 statistical methodologies: catastrophe and 2-part growth mixture modeling. Drawing on previous investigations of self-efficacy as a dynamic predictor of relapse, the current study revisits the self-efficacy matching hypothesis, which was not statistically supported in Project MATCH. Results from both the catastrophe and growth mixture analyses demonstrated a dynamic relationship between self-efficacy and drinking outcomes. The growth mixture analyses provided evidence in support of the original matching hypothesis: Individuals with lower self-efficacy who received cognitive behavior therapy drank far less frequently than did those with low self-efficacy who received motivational therapy. These results highlight the dynamical nature of the relapse process and the importance of the use of methodologies that accommodate this complexity when evaluating treatment outcomes. 相似文献

In contrast to Shultz and Takane [Shultz, T.R., & Takane, Y. (2007). Rule following and rule use in the balance-scale task. Cognition, in press, doi:10.1016/j.cognition.2006.12.004.] we do not accept that the traditional Rule Assessment Method (RAM) of scoring responses on the balance scale task has advantages over latent class analysis (LCA): RAM is similar to a very restricted form of LCA. The apparent shortcomings of LCA are also less severe than they suggest. Via new simulations we show that LCA detects small classes reliably. We also counter their concerns regarding the torque difference effect and we underline the problems connectionist models have with correctly responding to balance items. Despite these differences in opinion we agree with Shultz and Takane on the possible avenues for future research. 相似文献
