Multi-attribute choice and affect: The influence of naturally occurring and manipulated moods on choice processes

Based on a two-dimensional model of affect that views Pleasantness and Arousal as affect's two primary dimensions, this study investigates the effects of emotions on choice processes and outcomes. In Study 1, subjects first described their naturally occurring emotional state and then performed two multi-attribute product choice tasks. Subjects in more pleasant mood deliberated longer, used more decision-related information, re-examined more previously examined information, and made more interdimensional moves. Subjects in more aroused mood spent less time deliberating, revealed less information, ignored more product-describing attributes, and re-examined less of previously examined information. Study 2 replicated many of these effects with experimentally manipulated emotions and using a managerial decision-making task. The results are interpreted in terms of (1) a congruency between one's hedonic state and selected decision strategy and (2) a restriction in attentional capacity induced by increased Arousal.     

Comparison selection: An approach to the study of consumer judgment and choice

We introduce an alternative perspective on the study of consumer judgment and decision making, which is based on the notion that judgment and choice problems consist of comparisons that decision makers might select. Our new perspective proposes that if we can predict the likelihood that particular comparisons will become focal in a judgment or choice task, we will be able to gain a better understanding of and anticipate the resulting effect. Building on related literatures, we propose that comparison selection is driven by the task's latitude of acceptance (LOA) and comparison fluency (i.e., the overall ease of making that comparison). The task's LOA curve represents the range and concentration of potentially acceptable comparisons, whereas comparison fluency refers to the salience and ease of making the comparison. We illustrate our approach using previously studied problems (e.g., choice, variety seeking, the “jacket and calculator” problem, and contingent valuation) as well as new empirical tests.     

论健康权的国际合作与援助义务

目前,在全球健康领域存在诸多不平等,各国均有义务对外开展合作与援助。这种健康权的国际合作与援助义务主要以国际法规则和有关政治承诺为基础,由此也明确了该义务的依据和范围。我国作为发展中的大国,要辩证地看待这项国际义务：既应积极履行该项国际义务,同时也要努力寻求国际合作,并完善本国健康权保护体系。     

Rethinking Affective Experience and Popular Emotion: World War I and the Construction of Group Emotion in International Relations

Research in International Relations (IR) frequently confronts claims about the emotions shared by members of a group. While much attention has been devoted to the potential for affective and emotional experience beyond the individual level, IR scholars have said less about the politics of invoking popular emotion. This article addresses that gap. Specifically, we argue that between individual—and even shared—affective experience on the one hand and group‐based “popular emotion” on the other exists not mechanisms of aggregation but rather processes of framing, projection, and propagation that are deeply political. We distinguish between two tropes that commonly structure references to popular emotion: communal emotion, the idealized attribution of an authentic, unifying emotional response of “the people,” and mass emotion, a volatile and potentially dangerous mob‐like reaction, but one also susceptible to manipulation. Using the outbreak of World War I as a showcase, we demonstrate the political significance of popular emotion, including its enduring relevance for understanding contemporary populism.     

Concurrent choice: Effects of overall reinforcer rate and the temporal distribution of reinforcers

Six pigeons responded on a series of concurrent exponential variable-interval schedules, offering a within-subject comparison with previously published data from concurrent arithmetic variable-interval schedules. Both relative and overall reinforcer rates were varied between conditions. The generalized matching law described the data well, with undermatching much more frequent than strict matching. Time-allocation sensitivity consistently exceeded response-allocation sensitivity for both schedule types, and exponential-schedule sensitivity exceeded arithmetic-schedule sensitivity for both measures of choice. A further set of conditions using variable-interval schedules whose shortest interval was correlated with the mean interval, like arithmetic schedules, but that provided a constant conditional probability of reinforcement, like exponential schedules, produced sensitivities between those produced by conventional arithmetic and exponential schedules. Unlike previous arithmetic-schedule results, exponential sensitivity changed nonmonotonically with changes in overall reinforcer rate. The results clarify our knowledge of the effects of arithmetic and exponential schedules but confuse our understanding of the effects of overall reinforcer rate on concurrent choice.     

跨期选择的变易程度正向预测中华文化圈国民的自评扛疫成效：亚非欧美大洋洲18国跨国研究

跨期选择是对不同时间点的得失的权衡与选择。伊索寓言《蚂蚁和蚱蜢》假借群居型昆虫的跨期选择偏爱暗喻投资未来的慢策略比只顾眼前的快策略更利于生存。用跨期选择领域通用的语言解读这一寓言便是：选择大而迟选项的蚂蚁比选择小而早选项的蚱蜢更可能扛过严冬而生存下来。为了探索何种跨期选择策略更有助于我们扛过疫情,本研究调查了亚非欧美大洋洲这5大洲18个国家共计26355名受测者对混合得失双结果的跨期选择偏爱,测量了人们平时和疫时跨期选择偏爱的变易程度(2类变易的程度指标),以及人们自评的扛疫成效。跨文化比较结果的主要发现是：不同通货的选择变易程度(指标1)和不同时期的选择变易程度(指标2)能联合预测中国/新加坡文化圈国民的自评扛疫成效;不同时期的选择变易程度(指标2)也可以单独预测印度/马来西亚/菲律宾/尼日利亚文化圈国民的自评扛疫成效;这2类选择偏爱变易的程度指标不能预测其他文化圈国民的自评扛疫成效(或者预测方向和假设相反)。基于易经“穷则变,变则通”的要旨和跨国比较的发现,我们认为：面临历史危机时善于变通的特长抑或成就了中华民族特有的竞争优势;在应对危机时,与中国文化距离越相近的国家或民族抑或也能...
