相关维度数量对两种结构类别学习的影响

在多重系统理论研究基础上,运用即时反馈训练范式,以大学生为被试,考查相关维度数量对基于规则和信息整合两种结构的类别学习的影响.结果表明:(1)相关维度数量是影响类别学习的重要因素,基于规则单维度结构的学习显著优于信息整合结构和基于规则双维度结构的学习,基于规则双维度结构的学习与信息整合结构的学习没有显著差异.(2)反应策略受到规则复杂性的影响,当类别结构中隐含的规则比较简单时,学习者使用规则策略;当类别结构中隐含的规则比较复杂时,学习者难以掌握规则,就会使用相似性策略.研究结果支持"难度观",而不支持多重系统理论.     

Transfer of hue matching in pigeons.

Pigeons were trained on a modified three-key matching-to-sample procedure, in which only one comparison key (rather than two) was lighted after an observing response to the center-key standard. Pecks on keys of matching comparison hues were reinforced. When non-matching hues appeared as the initially lighted comparisons, the nonmatching hue terminated and the matching hue appeared on the other side key only if the pigeon did not peck the nonmatching comparison for 4.8 sec. Pecks to the nonmatching hue reset the 4.8-sec delay interval. Three hues were used during acquisition. During transfer tests, two novel hues were substituted individually or together for one or two of the training hues. Latencies to the novel side-key hue were shortest when a novel matching hue appeared as the standard on the center key, and were essentially identical to baseline matching latencies. In contrast, when a novel hue appeared as either a standard or comparison in a nonmatching combination, latencies increased with increasing separation between the noevel hue and the nonmatching hue. These transfer data demonstrate the concept of hue matching.     

On the distinction between open and closed economies.

Open and closed economies have been assumed to produce opposite relations between responding and the programmed density of reward (the amount of reward divided by its cost). Experimental procedures that are treated as open economies typically dissociate responding and total reward by providing supplemental income outside the experimental session; procedures construed as closed economies do not. In an open economy responding is assumed to be directly related to reward density, whereas in a closed economy responding is assumed to be inversely related to reward density. In contrast to this predicted correlation between response-reward relations and type of economy, behavior regulation theory predicts both direct and inverse relations in both open and closed economies. Specifically, responding should be a bitonic function of reward density regardless of the type of economy and is dependent only on the ratio of the schedule terms rather than on their absolute size. These predictions were tested by four experiments in which pigeons' key pecking produced food on fixed-ratio and variable-interval schedules over a range of reward magnitudes and under several open- and closed-economy procedures. The results better supported the behavior regulation view by showing a general bitonic function between key pecking and food density in all conditions. In most cases, the absolute size of the schedule requirement and the magnitude of reward had no effect; equal ratios of these terms produced approximately equal responding.     

4～5岁儿童单双维类比推理能力的发展水平和特点

研究了儿童单双维类比推理能力的发展水平和特点。被试为 4岁到 5岁儿童 4 2名 ,男 19名 ,女 2 3名。三种实验条件分别为控制组、单维组、双维组 ,采用体现因果关系的图片类比推理材料。结果表明 :在具备相应知识经验的前提下 ,4岁组到 5 5岁组儿童的单维类比推理能力已接近形成 ,没有显著的年龄差异 ;4岁组到 5 5岁组儿童的双维类比推理能力均还处于较低的发展水平 ,但年龄差异显著 ,其中 5 5岁组儿童明显优于 5岁组 ,5岁组和 4 5岁组之间没有显著差异 ,4 5岁组显著优于 4岁组 ,在一定程度上反映出 4 5～ 5 5岁为儿童发展双维类比推理的“快速增长期”。实验中没有发现“练习效应”。     

医学人文与医疗实践结合:人性化的医疗

医学人文与医学科学的结合是当代科学与人文关系的特点和本性,也是医学现实的迫切需求,其目标是实现人性化的医疗;医学人文存在不同水平的三个层次;医疗人性化是一个广阔的领域;营造平台是促进两者结合的重要条件.医学人文具有理论和实践两个向度,医学人文的实践向度是整个医学人文或人文医学的基础,没有实践向度,理论向度就失去了基础,整个医学人文就会成为不着边际的空话.医学人文的理论向度和实践向度,其基础都在临床实践.     

Effects of a Motivational Interviewing–Based Counseling Program on Classroom Behavior of Children in a Disciplinary Alternative Education Program

A multiple single‐case research design was used to explore changes in teacher‐reported behaviors of 15 children who completed a motivational interviewing–based counseling program in a disciplinary alternative education school. Findings indicated that 7 children made a moderate to large improvement in their classroom behaviors while participating in the program. Students’ self‐motivational statements and self‐reported readiness to change were related to actual teacher‐rated behavioral changes. Implications for future research and counseling practice were discussed.     

The role of the oath in credibility assessment

Based on the adaptive lie detector theory, this study is an examination of whether taking an oath, as context‐general information, increases the credibility of a suspect. The consistency of the testimonies of 6 eyewitnesses was manipulated so that it could be used as individuating information. There were 2 sets of testimonies: one that was consistent and one that was inconsistent. The results supported the adaptive lie detector theory. The participants judged those persons who took an oath to be more credible than those who did not, but this only happened in situations where the testimonies of the eyewitnesses were inconsistent. The theoretical and practical implications of the findings and future directions are then discussed.     

Pain and Bodily Care: Whose Body Matters?

Pain is unpleasant. It is something that one avoids as much as possible. One might then claim that one wants to avoid pain because one cares about one's body. On this view, individuals who do not experience pain as unpleasant and to be avoided, like patients with pain asymbolia, do not care about their body. This conception of pain has been recently defended by Bain [2014 Bain, D. 2014. Pains That Don't Hurt, Australasian Journal of Philosophy 92/2: 305–20.[Taylor & Francis Online], [Web of Science ®] , [Google Scholar]] and Klein [forthcoming Klein, C. forthcoming. What Pain Asymbolia Really Shows, Mind. [Google Scholar]]. In their view, one needs to care about one's body for pain to have motivational force. But does one need to care about one's body qua one's own? Or does one merely need to care about the body that happens to be one's own? In this paper, I will consider various interpretations of the notion of bodily care, in light of a series of pathological cases in which patients report pain in a body part that they do not experience as their own. These cases are problematic if one adopts a first-personal interpretation of bodily care, according to which pain requires one to care about what is represented as one's own body. The objection can run as follows. If the patients experience the body part as alien, then they should not care about it. Therefore, they should be similar to patients with pain asymbolia. But they are not. Hence, bodily care is not necessary to pain. To resist this conclusion, one can try to revise the interpretation of the notion of bodily care and to offer alternative interpretations that are not first-personal. However, I will show that that those alternatives also fail to account for these borderline cases of pain.     

群体性事件集群行为的动员与组织机制

群体性事件指部分群众与当地党政部门或强势社会集团的对抗性冲突。是当下我国典型的集群行为。社会心理学对集群行为动员机制的研究主要包括群体相对剥夺、群体认同、群体(愤怒)情绪和群体效能; 对集群行为组织机制的研究主要包括速生规范、谣言和去个体化。其中, 群体愤怒和群体效能既属于动员机制, 同时又在组织机制中发挥作用。这些因素之间有待于进一步整合, 以期对现阶段我国社会频发的群体性事件的心理因素进行解释和探讨。     

任务维度和任务无关维度干扰信息的同质性影响视觉搜索的神经机制

在三个实验中, 我们利用功能性磁共振成像(functional magnetic resonance imaging, fMRI)技术考察了在简单特征搜索任务和客体内联合搜索任务中任务维度干扰项的同质性(或称一致性, homogeneity)和任务无关维度干扰信息的同质性对视觉搜索行为的影响及其神经机制。主要探讨了三个问题：(1) 任务维度干扰信息的同质性与目标存在性之间交互作用的神经机制; (2) 任务维度干扰信息的同质性与任务无关维度干扰信息的同质性之间的交互作用及其神经机制; (3) 上述神经机制在不同类型的视觉搜索(特征搜索和联合搜索)中的异同。
