The Effects of Frequency of Social Interaction and Relationship Closeness on Reward Allocation

In this study of how the frequency of interaction affects decisions on reward allocation, 320 Chinese adults were randomly assigned to 8 conditions and instructed to read a scenario describing 2 co-workers completing a task and obtaining a bonus. The 8 conditions differed in the type of relationships, the frequency of past interaction between co-workers, and the possibility of future interaction. Each participant was instructed to act as the allocator and to hypothetically allocate a monetary reward to the co-worker. The results indicated that both past interaction and future interaction between the co-workers significantly influenced the allocation decision. These results also suggested that the frequency of 2 individuals' past interaction can be predictive of the closeness of their relationship.

分配情境下的婴幼儿公平敏感性

公平一直是道德规范领域的中心议题。公平敏感性是指个体对感知到的公平和不公平的稳定而个性化的反应, 随着自身成长具有一定可变性。本文首先介绍了公平敏感性的概念界定以及研究方法, 认为第三方范式的引入使得婴幼儿研究的结果更加积极; 然后对分配情境下公平敏感性的影响因素进行了探讨, 如社会情境、社会关系、分配资源等; 最后, 指出未来研究应将公平敏感性概念具体化, 对分配情境下各因素进行协调整合, 匹配跨文化跨年龄组条件以系统探讨婴幼儿公平敏感性。     

RSVP任务下双刺激重复的优势与劣势

本研究探讨重复知盲发生在知觉阶段还是在记忆阶段。采用快速视觉系列呈现(rapid serial visual representation, 简称RSVP)任务, 让被试即时回忆80个词表中呈现的词。操作了词表中目标词的重复数, 分为无重复、单刺激重复(重复一对)和双刺激重复(重复两对)三种, 和目标词的情绪效价, 分为中性词和情绪词两种。结果发现, 对目标词回忆的正确率是：当目标词和非目标词都是中性词汇, 即二者的情绪效价强度相当时(实验1), 在无重复条件与双刺激重复条件下无差异, 二者均大于单刺激重复条件; 当目标词是消极词汇, 非目标词是中性词汇, 即目标刺激的情绪效价强度大于非目标刺激时(实验2), 无重复条件与单刺激重复条件无差异, 二者均大于双刺激重复条件。结果表明：(1)RSVP 任务下词表中有双刺激重复时, 如果刺激的效价强度相当, 出现重复优势; 如果目标刺激的效价强度高于非目标刺激, 出现重复劣势; (2)人们会主动分配更多的注意资源给效价高的刺激, 重复知盲产生在记忆阶段, 支持注意资源分配最优化假设。     

卫生资源配置与改善医患关系

从基本卫生资源配置角度来探讨如何改善医患关系,认为基本卫生资源配置失衡是引起医患纠纷的重要因素,从而指出公平优先原则指导下的基本卫生资源配置有利于改变医患关系紧张的现状,并据此观点提出实现基本卫生资源配置公平优先的相关保障措施.     

Concurrent variable‐interval variable‐ratio schedules in a dynamic choice environment

Most studies of operant choice have focused on presenting subjects with a fixed pair of schedules across many experimental sessions. Using these methods, studies of concurrent variable‐ interval variable‐ratio schedules helped to evaluate theories of choice. More recently, a growing literature has focused on dynamic choice behavior. Those dynamic choice studies have analyzed behavior on a number of different time scales using concurrent variable‐interval schedules. Following the dynamic choice approach, the present experiment examined performance on concurrent variable‐interval variable‐ratio schedules in a rapidly changing environment. Our objectives were to compare performance on concurrent variable‐interval variable‐ratio schedules with extant data on concurrent variable‐interval variable‐interval schedules using a dynamic choice procedure and to extend earlier work on concurrent variable‐interval variable‐ratio schedules. We analyzed performances at different time scales, finding strong similarities between concurrent variable‐interval variable‐interval and concurrent variable‐interval variable‐ ratio performance within dynamic choice procedures. Time‐based measures revealed almost identical performance in the two procedures compared with response‐based measures, supporting the view that choice is best understood as time allocation. Performance at the smaller time scale of visits accorded with the tendency seen in earlier research toward developing a pattern of strong preference for and long visits to the richer alternative paired with brief “samples” at the leaner alternative (“fix and sample”).     

小学儿童学习时间分配决策水平的发展

利用自由回忆,线索回忆和再认三种提取方式,以儿童任务难度预见（EOL）的判断等级与学习时间分配之间的G相关值作为指标,考察了小学儿童学习时间分配决策水平的发展过程。小学2、4、6年级儿童和成人大学生(作为对照)参与本研究,每个年龄组各24人。主要研究结果表明：（1）总体而言,小学各年级儿童,其学习时间分配的决策都受对任务难度预见等级的制约,对EOL判断等级越高的项目,分配的学习时间越长,说明小学儿童具有一定程度的学习时间分配的决策能力;（2）在自由回忆条件下,小学4年级和小学6年级儿童对EOL的判断等级与学习时间之间的G相关值差异显著,表明儿童的决策水平由小学4年级到小学6年级表现出快速发展的趋势;（3）在线索回忆的条件下,小学2年级和4年级儿童G相关值有显著差异,表明决策水平由小学2年级到小学4年级之间有快速发展的趋势;（4）在再认的条件下,小学各年龄儿童学习时间分配的决策水平没有显著性差异,表明再认条件下小学阶段的决策水平进步不显著;（5）在三种提取方式下,小学儿童对任务难度预见判断等级与首次学习时间之间的G相关值都不同程度地低于与总的学习时间之间的相关值。这说明小学儿童在反复学习的过程中在不断调整自己的学习时间分配,调整的程度有随年龄增长而加大的趋势。小学6年级儿童在任务难度预见判断等级与学习时间之间的G相关值已接近成人水平。     

论影响卫生资源分配公平性的因素

公平分配卫生资源是促进社会公正的重要方面.观念、体制与政策是影响卫生资源公平分配的重要因素.重医疗、轻预防的观念使宏观卫生资源分配失去公平,而城市尤其是大中城市优先的制度安排、按医疗项目付费方式的弊端、医疗保障体制的不公平等体制与政策因素则使微观卫生资源分配失去公平.从观念因素、体制与政策因素两个方面入手,改进卫生资源分配的公平性,是我国提高全民健康水平、促进社会公正的必由之路.     

Welfare policies and adolescents: exploring the roles of sibling care, maternal work schedules, and economic resources

This study uses data from three longitudinal experimental evaluations of US state welfare reform programs to examine whether program‐induced changes in families' reliance on sibling care are linked with the effects of welfare programs on selected schooling outcomes of high risk, low‐income adolescents. The findings from two of the welfare programs indicate that increased reliance on sibling care was concomitant with unfavorable effects of the programs on adolescent schooling outcomes. In the third welfare program examined, the program did not yield any increases in the use of sibling care or unfavorable effects on adolescent schooling outcomes, suggesting that sibling care is one likely contributor to the negative effects of welfare programs on adolescent schooling outcomes. These findings are discussed in terms of the pattern of the programs’ effects on families' income, as well as maternal work on nonstandard schedules, aside from the programs’ effects on maternal employment, which play contributory roles in shaping the extent to which welfare programs led to less favorable effects on the schooling outcomes of adolescents with younger siblings.     

Preference for distribution by equal outcome in 5- and 6-year-old children

This study investigated preferences for types of fairness applied in resource distribution. We consider two types of equal distribution: according to the equal-allocation principle (new resources are distributed evenly without considering currently possessed resources) or the equal-outcome principle (equal outcome amounts result after distribution because current resources are considered). Children aged 5–6 and adults participated. The participant initially had two sets of two marbles (participant condition) or each of two puppets initially had two marbles (puppet condition). Then one puppet distributed new marbles between itself and the participant by equal-outcome. Next, the other puppet distributed new marbles by equal-allocation. The results showed that the majority of children and adults selected the distribution by equal-outcome for both conditions. This suggests that people prefer distribution by equal-outcome to distribution by equal-allocation. However, some children aged 5–6 thought that distribution by equal-allocation was better only when they already had resources.
