从自我决定论看动机访谈法疗效机理

动机访谈法是以病人为中心、促使病人自己改变问题行为的咨询技术和方法。该文从自我决定论角度,解释了动机访谈法取得疗效的机理:动机访谈法起到满足病人基本心理需要(胜任感、归属感、自主性),推动病人产生自主动机的作用,促使病人提高适应性行为的质量和稳定性,提高心理健康水平,从而取得心理治疗效果。

Relationship between psychological stress and lymphocytic 5′-ectonucleotidase

The relationship between psychological stress and lymphocytic 5-ectonucleotidase, an enzyme marker for lymphocyte differentiation, was studied. Lymphocytic 5-ectonucleotidase was decreased significantly by about twofold in persons experiencing psychological stress, with a corresponding change in Total Mood Disturbance scores of the Profile of Mood States. Enzyme values were reversible in that they returned to normal once the stress had been reduced. Administration of high doses of ascorbate to severely depressed patients also normalized 5-ectonucleotidase activities, and implied that low enzyme values in stressed persons may be mediated by oxygen radical damage. This finding was consistent with previous reports of heightened inflammatory responses occurring in depressed patients. The primary cause of lowered 5-ectonucleotidase during stress may be the breakdown in the homeostatic mechanisms of the hypothalamic-pituitary-adrenal axis and immune system resulting in lymphoid tissue resistance to corticosteroids. It is suggested that this lowering of lymphocyte 5-ectonucleotidase may contribute to stress-mediated immune suppression by inhibiting lymphocyte maturation.     

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.     

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。     

大脑前扣带回皮层与执行功能

回顾了近期有关大脑前扣带回皮层（ACC）参与执行功能的研究资料。结果显示,ACC可以对正在进行的目标定向行为实施在线监控,在出现反应冲突或错误时提供信号,以便能及时调整与分配注意资源,因此可能是一个行为规划与执行的高级调控结构。这两年来的新发现提示,ACC的执行监控作用可能是基于动机与奖赏期待做出的对“意志行动”的整合性控制,并可能具有对行动结果的情绪评价意义。     

Coordination tending towards an anti-phase relationship determines greater sway reduction during entrainment with a simulated partner

The increased risk of falls in the older aged population demands the development of assistive robotic devices capable of effective balance support. For the development and increased user acceptance of such devices, which provide balance support in a human-like way, it is important to understand the simultaneous occurrence of entrainment and sway reduction in human-human interaction. However, sway reduction has not been observed yet during a human touching an external, continuously moving reference, which rather increased human body sway. Therefore, we investigated in 15 healthy young adults (27.20±3.55 years, 6 females) how different simulated sway-responsive interaction partners with different coupling modes affect sway entrainment, sway reduction and relative interpersonal coordination, as well as how these human behaviours differ depending on the individual body schema accuracy. For this, participants were lightly touching a haptic device that either played back an average pre-recorded sway trajectory (“Playback”) or moved based on the sway trajectory simulated by a single-inverted pendulum model with either a positive (Attractor) or negative (Repulsor) coupling to participant's body sway. We found that body sway reduced not only during the Repulsor-interaction, but also during the Playback-interaction. These interactions also showed a relative interpersonal coordination tending more towards an anti-phase relationship, especially the Repulsor. Moreover, the Repulsor led to the strongest sway entrainment. Finally, a better body schema contributed to a reduced body sway in both the “reliable” Repulsor and the “less reliable” Attractor mode. Consequently, a relative interpersonal coordination tending more towards an anti-phase relationship and an accurate body schema are important to facilitate sway reduction.
