In this paper, we propose a (n–1)2 parameter, multistage ranking model, which represents a generalization of Luce's model. We propose then×n item-rank relative frequency matrix (p-matrix) as a device for summarizing a set of rankings. As an alternative to the traditional maximum likelihood estimation, for the proposed model we suggest a method which estimates the parameters from thep-matrix. An illustrative numerical example is given. The proposed model and its differences from Luce's model are briefly discussed. We also show some specialp-matrix patterns possessed by the Thurstonian models and distance-based models. 相似文献

The PARELLA model is a probabilistic parallelogram model that can be used for the measurement of latent attitudes or latent
preferences. The data analyzed are the dichotomous responses of persons to items, with a one (zero) indicating agreement (disagreement)
with the content of the item. The model provides a unidimensional representation of persons and items. The response probabilities
are a function of the distance between person and item: the smaller the distance, the larger the probability that a person
will agree with the content of the item. This paper discusses how the approach to differential item functioning presented
by Thissen, Steinberg, and Wainer can be implemented for the PARELLA model.

探究源自环境的恢复体验(如,放松、平静等)对居住者地方依恋(包括地方依赖和地方认同两个维度)的预测作用,并分析其中的内在过程与情境条件。采用问卷研究法(N=410),结果发现:(1)恢复体验能显著正向预测个体地方依恋;(2)环境偏好在恢复体验与地方依恋之间起完全中介作用;(3)居住时长调节环境偏好与地方依恋(主要是地方认同)之间的关系。研究将有助于探寻环境心理学视角下的压力管理与城市管理协同路径。 相似文献

相关研究表明,由于青少年在网络社交中能够获得他人的认可与支持,网络社交对网络成瘾具有显著的影响。自我价值定向理论认为自我价值是人们行为的终极理由,其中他人的认可与接纳、家庭社会经济地位都是自我价值的重要支撑。当青少年生活在高社会经济地位环境中,其自我价值可能越高,网络社交使用频率对网络成瘾的影响可能会减弱。我们从全国7个省收集了1216份青少年自评的网络社交使用频率、网络成瘾倾向以及父母自评的社会经济地位等指标的数据。结果表明:家庭社会经济地位调节着网络社交使用频率与网络成瘾倾向的关系;进一步的分析表明,在高社会经济地位的家庭中,青少年的网络社交使用频率对网络成瘾倾向的影响不显著,而在低社会经济地位的家庭中,青少年的网络社交使用频率对网络成瘾倾向的影响极其显著。结果支持了自我价值定向理论。 相似文献

The logic of an ought operator O is contranegative with respect to an underlying preference relation if it satisfies the property Op & (¬p)(¬q) Oq. Here the condition that is interpolative ((p (pq) q) (q (pq) p)) is shown to be necessary and sufficient for all -contranegative preference relations to satisfy the plausible deontic postulates agglomeration (Op & OqO(p&q)) and disjunctive division (O(p&q) Op Oq). 相似文献

The collection of repeated measures in psychological research is one of the most common data collection formats employed in survey and experimental research. The behavioral decision theory literature documents the existence of the dynamic evolution of preferences that occur over time and experience due to learning, exposure to additional information, fatigue, cognitive storage limitations, etc. We introduce a Bayesian dynamic linear methodology employing an empirical Bayes estimation framework that permits the detection and modeling of such potential changes to the underlying preference utility structure of the respondent. An illustration of revealed stated preference analysis (i.e., conjoint analysis) is given involving students’ preferences for apartments and their underlying attributes and features. We also present the results of several simulations demonstrating the ability of the proposed procedure to recover a variety of different sources of dynamics that may surface with preference elicitation over repeated sequential measurement. Finally, directions for future research are discussed.The authors wish to acknowledge and thank the Editor, the Associate Editor, and two anonymous reviewers for their constructive and insightful comments.

Content analysis of birth announcements was used as a method to investigate parental preference for the sex of newborns in Canada. The expression of positive affect (happiness and pride) in birth announcements was examined to determine whether parents express these emotions differently as a function of the sex of newborn. The findings suggest that parents express relatively more pride at the birth of boys than girls, whereas the opposite results were found for happiness. Parents seem unconsciously to categorize boys and girls into two distinct motivational systems: status and attachment, which are related to pride and happiness, respectively. This distinction may influence parents perception of their childs worth and their subsequent investment in their childs development. 相似文献

This study investigated the extent to which interspersing effects are consistent with the effects of reinforcement on predicting students preferences for mathematics assignments. Students were exposed to 4 pairs of assignments. Each assignment pair contained a control assignment with 15 problems requiring multiplication of a three digit number by a two digit number, and an experimental assignment consisting of 15 similar multiplication problems plus additional brief one-digit by one-digit multiplication problems interspersed at four different rates (i.e., no interspersing, every other, every third, or every fifth problem) across assignment pairs. Performance data were collected for accuracy, total problem completion rate and target problem completion rate. In addition to performance data, students were asked to rate each assignment with regard to relative difficulty, time, effort to complete, and preference between assignments for homework. Results suggest that although interspersing rates do not affect accuracy, they do affect problem completion rate, and student preferences for academic assignments. Discussion focuses on interspersing rate and schedules of reinforcement with emphasis on both applied and theoretical implications. 相似文献

We evaluated the long-term therapeutic effects of noncontingent reinforcement (NCR). In Experiment 1, NCR effects were examined with 2 participants' arbitrary responses; in Experiment 2, NCR was used as treatment with 3 participants whose self-injurious behavior (SIB) was maintained by automatic reinforcement. In both experiments, NCR consisted of continuous access to a highly preferred leisure item and was implemented initially during 10-min and later during 120-min sessions. Varied reinforcers (leisure items) were subsequently introduced during 120-min sessions to determine if treatment effects might be extended. Finally (Experiment 2 only), NCR was implemented throughout the day in participants' homes. Results of Experiments 1 and 2 showed that reinforcers obtained through object manipulation can compete with those obtained automatically by engaging in SIB during brief NCR sessions. However, data from the 120-min sessions indicated that satiation to a specific leisure item might occur over periods of time more typical of those during which treatment would be implemented. Access to a variety of highly preferred leisure items extended the effectiveness of NCR for some individuals. When NCR was implemented throughout the day (Experiment 2), therapeutic effects were shown to be maintained for up to 1 year. 相似文献
