Preference Structure Modelling for Multi-objective Decision Making: A Goal–Programming Approach

We propose a new approach for modelling preference structures in multi-objective decision-making (MODM) problems. The basic idea of the approach is to first develop PROMETHEE-influenced objective functions and then to use these to reformulate the problem as a distance-based goal–programming (GP) model. Three basic functional forms are proposed and explicit expressions are developed for them. Among other things, the expressions allow for the straightforward development of an interactive framework while keeping the information requirements from the decision maker (DM) at a minimum. An ‘automatic’ piecewise linear approximation scheme is proposed for solving the GP model. © 1997 by John Wiley & Sons, Ltd. J. Multi-Crit. Decis. Anal. 6 : 150–154 (1997) No. of Figures: 0.

消费者基于选择集的情境效应

消费者基于选择集的情境效应颠覆了传统的理性选择理论,表明了情境对消费者偏好和选择的系统性影响。情境效应主要的类型有吸引效应和折衷效应。情境效应具有感知偏差、风险和负面情绪规避以及信息推理等方面的内在机理。选择集结构和特征及消费者等因素都对情境效应产生影响,而情境效应会影响消费者偏好的构建。未来情境效应研究将会向复杂属性组合、复杂购买情境和新情境效应的发现等方面拓展。     

消费行为研究中的联合分析法

联合分析(Conjoint Analysis)是一种定量的研究消费者选择偏好的方法。虽然从它诞生到现在只有40年的历史,但它对消费者行为学的影响很大,它的发展更是日新月异。文章首先介绍了联合分析的基本概念,然后重点阐述了联合分析的原理、步骤和发展历程,最后对联合分析的发展方向作了一个简要概括。     

风险决策中动态框架效应研究

风险决策的框架效应一直是理论研究和实践应用的焦点。该研究利用计算机联网模拟团队分布式动态风险决策任务,从三个方面（过去绩效,启动资金和目标设置）研究决策者在动态条件下风险偏好的变化规律。研究发现“目标设置”因素框架效应具有抑制作用,“启动资金”因素对个体和团队有不同影响。研究结果表明,风险敏感性同样适用于解释动态情境下的风险偏好。     

Assessing preferences of individuals with developmental disabilities using alternative stimulus modalities: A systematic review

The purpose of this systematic review was to identify investigations comparing the efficacy of alternative modality (e.g., pictorial, verbal, video) stimulus preference assessments for individuals with developmental disabilities. We identified articles by searching peer‐reviewed journals using the PsycINFO and ERIC databases, conducting table of contents searches of common behavioral outlets, and conducting ancestral searches of recent reviews and practitioner summaries of preference assessment methodology. A total of 32 articles met our inclusion criteria. These studies were then coded across a variety of features to gain a better understanding of the efficacy of alternative format preference assessments for individuals with developmental disabilities. In addition, we reviewed this literature for the use of prerequisite‐skill assessments and contingent‐reinforcer access to further investigate the relation between these variables and the accuracy of pictorial, verbal, and video preference assessments. A variety of methodological concerns are discussed as well as suggestions for future research.     

A comparison of group contingencies on academic compliance

We used a reversal design with an embedded multielement design to compare the effects of an independent group contingency and a randomized dependent group contingency on compliance with assigned literacy worksheets in a first‐grade general education classroom. Nine participants were selected based on low levels of compliance in baseline or by teacher identification. Results indicated that both group contingencies increased compliance relative to baseline for the majority of participants. The independent condition produced higher levels of compliance for four students and the randomized dependent condition produced higher levels of compliance for one student. For four students, the two group contingencies were equally effective. A preference assessment indicated that the majority of target students preferred the randomized dependent condition and the majority of nontarget students preferred the independent condition. A number of potential explanations for our preference findings, including the possible role of obtained reinforcement, are discussed.     

Using stimulus preference assessments to identify preferred break environments

A pictorial preference assessment was conducted for 2 individuals with autism who had programmed breaks in their behavior plans. Assessed break environments were individualized, based on indirect assessments and direct observations. The most highly (HP) and least preferred (LP) environments and a control with no associated break were included in a subsequent reinforcer assessment using a concurrent‐chains arrangement within a reversal design. Participants selected a multitask sequence (initial link) associated with one of the break environments. Phase A evaluated the reinforcing properties of all three breaks; the HP was removed in Phase B. Both participants allocated more responding to HP than LP, and to LP than control, suggesting that breaks functioned as reinforcers. The results indicated that preference assessment technology can be used to identify highly preferred breaks that function as reinforcers. Social validity measures indicated that the individuals' clinicians found the results useful for future clinical programming.     

Effects of preference on performing a self-care skill among children with autism spectrum disorder

In this study, four children with autism were assessed to determine their preference choices for toothbrushes and toothpastes included during self-care skills teaching sessions. For two of the children, the presence of high-preference (HP) materials was associated with improved independent tooth brushing when compared to the presence of low-preference (LP) materials. There was no difference in independent tooth brushing between HP/LP conditions for the other two children. These findings suggest that preference and choice of materials alone can be a helpful instructional strategy for care providers serving children who have neurodevelopmental disorders and skill deficits.
