Three studies (N=539) examined the hypothesis that positive mood increases the degree to which epistemic motivation, i.e., the need for closure (NFC), affects the way in which an individual processes information (heuristic vs. systematic processing). In each of the studies, different methods of operationalising mood were used: in Study 1, mood was measured as a state; in Study 2, mood was induced by asking participants to recall emotional events; and in Study 3, mood was induced by emotional pictures. The styles of information processing that were utilised by our participants were operationalised in terms of their preferences for (Study 1) and ability to recall (Studies 2 and 3) schema-consistent and schema-inconsistent information. Taken together, the results of the three studies show that only under positive mood, NFC level of an individual is consistent with his or her style of information processing, that is, only under positive mood is there a negative relationship between the NFC level of an individual and the utilisation of schema-inconsistent information. Our results can be explained in terms of the effect that mood has on an individual's perceived ability to achieve NFC. 相似文献

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 study examined and compared the latent structure of posttraumatic growth (PTG) based on three proposed models: 1-factor, 3-factor and 5-factor models in order to (1) find out the factor structure that has the best fit for the Filipino sample; (2) find out the factor structure that best represents PTG in the immediate aftermath of a flash flood disaster; and (3) examine the generalizability of the best-fitted model across gender. A sample of 895 survivor-respondents answered the Posttraumatic Growth Inventory (PTGI) within a month after a deadly flash flood. Based on the best-fitted model, a multi-group comparison between male and female was conducted to determine gender generalizability. Results showed that the 3-factor model comprising of Changes in Self/Positive Life Attitudes, Philosophy of Life, and Relating to Others fitted best in contrast to the other two models. The data also demonstrated the generalizability of the 3-factor model across gender, with invariance in factor loadings, item intercepts, factor variance and covariance, and factor means. 相似文献

Extracting general rules from specific examples is important, as we must face the same challenge displayed in various formats. Previous studies have found that bimodal presentation of grammar‐like rules (e.g. ABA) enhanced 5‐month‐olds’ capacity to acquire a rule that infants failed to learn when the rule was presented with visual presentation of the shapes alone (circle‐triangle‐circle) or auditory presentation of the syllables (la‐ba‐la) alone. However, the mechanisms and constraints for this bimodal learning facilitation are still unknown. In this study, we used audio‐visual relation congruency between bimodal stimulation to disentangle possible facilitation sources. We exposed 8‐ to 10‐month‐old infants to an AAB sequence consisting of visual faces with affective expressions and/or auditory voices conveying emotions. Our results showed that infants were able to distinguish the learned AAB rule from other novel rules under bimodal stimulation when the affects in audio and visual stimuli were congruently paired (Experiments 1A and 2A). Infants failed to acquire the same rule when audio‐visual stimuli were incongruently matched (Experiment 2B) and when only the visual (Experiment 1B) or the audio (Experiment 1C) stimuli were presented. Our results highlight that bimodal facilitation in infant rule learning is not only dependent on better statistical probability and redundant sensory information, but also the relational congruency of audio‐visual information.

Some people might believe that individuals who are more satisfied with their body are also happier. However, people tend to overrate the influence of some factors (e.g. money or health) on their happiness; a phenomenon termed the focusing illusion. Our aim was to examine the focusing illusion in relation to body satisfaction. We experimentally manipulated body satisfaction and life satisfaction focus by varying the order of relevant measurement scales. Volunteers (N = 97) completed two questionnaires placed in separate envelopes to control the order of scales administration. Participants either completed the Body Satisfaction Scale followed by the Satisfaction with Life Scale or vice versa. In line with the focusing illusion the association between body satisfaction and life satisfaction was significantly stronger when participants were asked about their body satisfaction first. Body satisfaction as a focusing illusion may need to be considered by scientist as well as lay people who try to look better and be happier. 相似文献

Personalized recommendation has important implications in raising online shopping efficiency and increasing product sales. There has been wide interest in finding ways to provide more efficient personalized recommendations. Most existing studies focus on how to improve the accuracy and efficiency of the recommendation algorithms or are more concerned on ways to reduce perceived risks and thus increase consumer satisfaction. Unlike these studies, our study begins from the decision‐making process of consumers, using consumers' two‐stage decision‐making system and preference inconsistency theory as a basis, to reveal the mechanisms involved in consumers' acceptance of recommendations. This paper analyzes the effect of personalized recommendations from two angles, recommendation timing and product portfolio, tries to point out differences in consumer preferences between similar products and related products, and verifies that consumers demand diversity in the recommended content. The study analyzes differences in the acceptance of personalized recommendations between practical products and hedonic products and discovers that recommendations of hedonic products are more effective than that of practical products. Based on the research earlier, the study provides suggestions on how to better plan and operate a personalized recommendation system. Copyright © 2016 John Wiley & Sons, Ltd. 相似文献
