当代心理学文化兴起方法论困境与路向

今天的科学心理学执意于自然科学研究品格,试图将心理学创建成为有着与自然科学同样品质的学科门类,从而陷入科学与非科学之争的“康德式难题”尴尬境地。心理学文化兴起为学界提供了研究心理学与文化之间关系的新视角。但是,由于思维方式和方法论二元对立的局限性。使心理学走进了难以超越的困境。心理学文化兴起新路向在于思维方式的转向,从关注外在于人的文化或外在于文化的人转向对人的心理与文化之间的关联和互动层面。     

Inter-limb coordination and control in boys with and without DCD in ball catching

The purpose of the study was to examine the nature of inter-limb coordination and control, exhibited by ten boys with (M = 10.5 years, SD = 1.0) and without Developmental Coordination Disorder (DCD), in a ball catching task across different ball speeds. In line with the predictions of coordinated structure theory boys who were typically developing preserved strong and effective temporal relations when catching balls in baseline and fast conditions. Boys with DCD exhibited temporal symmetry in baseline but not in fast attempts, where the decoupling was uniformed across the group, coinciding with failures on ≥ 50% of the attempts. In terms of stability, no differences in intra-individual variability were observed between the groups. The analysis of spatial and temporal adaptations showed that boys who were typically developing, in essence, covered the same “ground” by decreasing their movement time. The opposite was true for boys with DCD who contacted the ball closer to the body, while failing to adapt the velocity of their hands. Taken together, both groups exhibited strong and stable coordinative relations, in a steady-state but not in a fast condition, where all boys with DCD failed to preserve the desired symmetry. This decoupling also coincided with different and less effective spatio-temporal adaptations at the effector level. Thus, it appears that movement control, hence flexibility of their synergistic relations, represents a movement limiter for boys with DCD who exhibit specific balls skills issues, at inter-limb level of organization. It should be noted, however, that large intra-group variance observed across some variables warrants caution when interpreting the aggregate data.     

Degrees of freedom and motor planning in purposive movement

This paper presents empirical evidence suggesting that healthy humans can perform a two degree of freedom visuo-motor pursuit tracking task with the same response time delay as a one degree of freedom task. In contrast, the time delay of the response is influenced markedly by the nature of the motor synergy required to produce it. We suggest a conceptual account of this evidence based on adaptive model theory, which combines theories of intermittency from psychology and adaptive optimal control from engineering. The intermittent response planning stage has a fixed period. It possesses multiple optimal trajectory generators such that multiple degrees of freedom can be planned concurrently, without requiring an increase in the planning period. In tasks which require unfamiliar motor synergies, or are deemed to be incompatible, internal adaptive models representing movement dynamics are inaccurate. This means that the actual response which is produced will deviate from the one which is planned. For a given target-response discrepancy, corrective response trajectories of longer duration are planned, consistent with the principle of speed-accuracy trade-off. Compared to familiar or compatible tasks, this results in a longer response time delay and reduced accuracy. From the standpoint of the intermittency approach, the findings of this study help make possible a more integral and predictive account of purposive action.     

Ethical and Philosophical Consideration of the Dual-use Dilemma in the Biological Sciences

The dual-use dilemma arises in the context of research in the biological and other sciences as a consequence of the fact that one and the same piece of scientific research sometimes has the potential to be used for bad as well as good purposes. It is an ethical dilemma since it is about promoting good in the context of the potential for also causing harm, e.g., the promotion of health in the context of providing the wherewithal for the killing of innocents. It is an ethical dilemma for the researcher because of the potential actions of others, e.g., malevolent non-researchers who might steal dangerous biological agents, or make use of the original researcher's work. And it is a dilemma for governments concerned with the security of their citizens, as well as their health. In this article we construct a taxonomy of types of "experiments of concern" in the biological sciences, and thereby map the terrain of ethical risk. We then provide a series of analyses of the ethical problems and considerations at issue in the dual-use dilemma, including the impermissibility of certain kinds of research and possible restrictions on dissemination of research results given the risks to health and security. Finally, we explore the main available institutional responses to some of the specific ethical problems posed by the dual-use dilemma in the biological sciences.

A simulation study of the degrees of freedom of movement in reaching and grasping

The question of independently controlled components in the act of reaching and grasping has attracted interest experimentally and theoretically. Data from 35 studies were recently found consistent with simulated kinematic finger and thumb trajectories optimised for minimum jerk. The present study closely reproduces those trajectories using a discrete-time model based on minimum acceleration. That model was further used to generate two-dimensional trajectories for finger and thumb to reach and grasp an elliptical object with varying position and/or orientation. Orthogonalisation of these four trajectories revealed one degree of freedom when direction of reach was constant and two degrees of freedom when direction of reach varied, irrespective of object distance and orientation. These simulations indicate that reach and grasp movements contain redundancy that is removable by formation of task-dependent synergies. As skilled movement can be planned and executed in a low dimension workspace, control of these independent components lessens central workload.     

囚徒困境决策中分离效应验证性与机制研究

Savage于1954年提出"确定事件原则"这一概念,Tversky和Slafir(1992)通过实验发现,人们在不确定条件下的决策过程中,会出现违背确定事件原则的现象,并把这种现象称为"分离效应"。尽管已经有很多对于二次赌博中分离效应的机制研究并产生很多分歧,但对于囚徒困境范式中是否存在分离效应以及其机制并没有一致的结果。本文对囚徒困境中的分离效应进行了验证性实验,虽然整体结果上与Shafir与Tversky(1992)的结论相吻合,但被试专业背景对结果有显著效应。同时,按照Lambdin和Burdsal(2007)对分离效应的操作定义,结果发现分离效应没有出现,文章对其原因进行了讨论。

社会价值取向和反馈方式对公共物品困境中决策行为的影响

本研究通过模拟投资实验和问卷来探讨重复型公共物品困境中社会价值取向（SVO）与信息反馈方式对决策行为的影响。结果表明：(1)合作型SVO的个体比非合作型个体表现出更多的合作行为;(2)SVO与信息反馈方式的交互作用岁实验轮次越来越显著,非合作型的个体会受信息反馈方式的影响,而合作型个体则不易受反馈方式的影响;(3)与无反馈的条件相比,集体反馈倾向于促进个体的合作行为,个体反馈倾向于抑制合作行为,但反馈所造成的适应性改变使情况更为复杂。     

权力感对道德困境判断的影响：基于CNI模型的分析

采用道德困境判断的CNI（consequence, norm, inaction）模型,通过两个实验考察权力感对道德困境判断的影响。实验1探讨个人权力感对道德困境判断的影响,结果显示高个人权力感显著增加被试对规则的敏感,促使个体做出道义论的道德判断。实验2考察回忆任务启动的权力感对道德困境判断的影响,发现相对于低权力感启动的被试,高权力感启动的被试在进行判断时更关注行为的结果,对规则更不敏感,这说明启动的权力感促进功利主义的道德判断,抑制道义论的道德判断。结果表明,不同类型的权力感对道德困境判断的影响存在差异。     

The Ethics of Opinion in Academe: Questions for an Ethical and Administrative Dilemma

If we accept that all plagiarism is wrong, the issue is black and white. But are there more challenging questions that color the issue with shades of gray that may influence or help clarify the ethical underpinnings of the act? Does intent matter? Does the venue matter? Does the form of writing matter? What about a professor when working as a private citizen, rather than in his/her academic role? Might plagiarism be mitigated when there is no associated financial gain? Is a writer’s history that exhibits impeccable ethical integrity relevant? Should these factors, and/or other factors, even be considered in a university’s administrative response — or non-response? What might employing an ethical approach contribute to wrestling with the dilemma? The authors explore critical issues that might face a senior academic administrator when confronting the need to respond on behalf of a university to a charge of plagiarism leveled by an influential newspaper against a university professor for a social responsibility-focused opinion-editorial published in this newspaper.     

The Butterfly Dilemma: Asian Women,Whiteness, and Heterosexual Relationships

Critical Whiteness theory explores Whiteness as a form of power and privilege that originated in Western countries and has been dispersed globally. Its form is particular to location and its interaction with race, ethnicity, nationality, class, and gender. Two ways it has operated historically is through making the norms of Whiteness universal and the marker of reason and rationality. This article examines Whiteness through two lenses, the colonial-era opera, Madame Butterfly, and three recent therapy case studies involving White American husbands and Asian immigrant wives. Although the women in these therapy cases have emigrated from different Asian countries and cultures, the treatment toward them suggests that colonial-era images and stereotypes of Asian women still resonate in contemporary White American culture and are impervious to national or cultural boundaries. A comparison of the opera’s themes with those of the therapy cases suggest how historical and social constructions of Whiteness continue to promote inequality in heterosexual relationships comprised of White American males and Asian females. Feminist, multicultural analyses of the therapy cases are provided to highlight more egalitarian treatment of the women in therapy, in their families, and in the broader society. The intersectionality of gender with ethnicity and culture is discussed for these Asian women who experience the homogenization of their identities in spite of having immigrated to the U.S. from distinct cultures.     

The training of psychoanalysts in Latin American countries without IPA institutions: antecedents, experiences and problems encountered

ILAP (The Latin American Institute of Psychoanalysis) is a relatively recent project of the IPA and FEPAL (The Latin American Psychoanalytical Federation). Its formal origin, marked by the signature of a memorandum recording an agreement between the presidents of both institutions, Claudio Eizirik and Alvaro Rey de Castro respectively, dates from January 2006, but the governing body of ILAP was formed in December of the same year. Given this, we might say that as of December 2008 ILAP had effectively existed for two years. This is a short and very intense period and for that reason the time for general assessment, conclusions, and suggestions for change has not yet come. We shall simply give a critical history of the project, its antecedents, what it has realized, and the difficulties and limitations encountered hitherto, as well as sketch future perspectives.

公共物品困境中的突显身份效应及合作动机对合作行为影响

从合作动机的激发与破坏的角度探讨公共物品困境中突显身份对合作行为的影响,同时考察社会价值取向与突显身份之间的关系。结果表明：突显合作者与突显不合作者两种方式都会提高被试的合作水平;两种突显方式的作用机制不同。突显合作者条件下,被试的合作行为受内在动机和外在动机的共同影响。而突显不合作者则会破坏被试合作的内在动机,外在动机对提高合作行为起主要作用;突显合作者条件下,合作取向的被试更多受内在动机的影响,而非合作取向的被试则更多受外在动机的影响。在突显不合作者的条件下,合作取向和非合作取向被试的合作行为都受外在动机的影响较大。     

Motor maps and synergies

Consider the process of raising and lowering the arm in the sagittal plane. Different parts of different muscles operate over different sectors of the angular range. How and why does the nervous system implement this differential muscle activation according to joint angle? We contend that such control depends on the adaptive formation of motor maps. These solve the problem of redundancy in the musculoskeletal system by connecting a relatively small number of cortical columns in the motor cortex to a large number of alpha motor neuron pools. We argue that motor maps are formed such that each functional muscle is activated in proportion to its moment arm about the movement. Because of this the required agonist and antagonist turning forces are generated with a minimum demand for metabolic energy. We know from biomechanical principles that, at any given posture, those muscle fibres that change length most in response to a small joint-angle change are those with the greatest moment arm. Likewise those that change least have the smallest. By establishing a model of the polynomial relationships between the lengths of functional muscles l and the corresponding changes in joint angles theta, the nervous system can generate signals partial differentiallj/ partial differentialthetai (where lj is the length of the jth functional muscle and thetai is the magnitude of the ith elemental movement). These signals create motor maps by modulating the gains of descending motor pathways. As a result, functional muscles are activated in proportion to their moment arms. This reduces the demand for metabolic energy to a minimum. Since moment arms change with joint angle, it also accounts for the experimental observations above. Such motor mapping effectively provides a minimum energy "wired-in" synergy. Established in utero, motor maps are the first stage of synergy formation and provide the basis for the development of subsequent task-dependent synergies.     

公共资源两难管理的社会学习过程和动机释放机制

公共资源两难的根本问题是个人经济利益与社会整体利益的矛盾。一些人为了追逐个人利益最大,过度获取公共资源,走向＂公共的悲剧＂,或不愿为公共资源作出贡献,＂搭便车＂现象流行。传统的研究从理性经济人的角度探讨公共资源两难博弈行为的机制,用＂贪婪＂来解释＂搭便车＂现象,并根据强化理论以奖励和惩罚作为主要对策。但是,这种理性经济人观点忽视了人的社会动机。实际上,公共资源两难博弈是一个社会互动的过程,人的社会心理因素在其中起了很重要的作用,因此在方法论上有必要从社会人（Homo socius）的人性观来进行分析。本文在当前的相关研究文献基础上,分析了公共资源两难博弈行为的动机模式,从社会学习理论出发,提出了公共资源两难管理的社会学习过程和动机释放机制。     

What the face and body reveal: in-group emotion effects and stereotyping of emotion in African American and European American children

This study examined whether 3- to 7-year-old African American and European American children’s assessment of emotion in face-only, face + body, and body-only photographic stimuli was affected by in-group emotion recognition effects and racial or gender stereotyping of emotion. Evidence for racial in-group effects was found, with European American children being more accurate when assessing emotion in European American photographs than African American photographs for some emotions. African American children were either equally proficient in recognizing emotion in African American and European American photographs or were more accurate with European American photographs for some emotions. Stereotyping of emotion was also found, with boys being more often labeled with “masculine” emotions (e.g., mad) and at least some girls being more often labeled with “feminine” emotions (e.g., happy). However, stereotyping effects were found only when the face was present in the stimuli and were not found with body-only stimuli. In-group effects, however, were not affected by type of photograph (face-only, body-only, or face + body), with children being unable to recognize at least some emotions from just the body postures alone (mad). These results have important implications for how future studies assess emotion recognition in children, particularly in terms of how emotion stimuli are constructed, the diversity of the stimuli, and who judges the stimuli.     

The Special Science Dilemma and How Culture Solves It

I argue that there is a tension between the claim that at least some kinds in the special sciences are multiply realized and the claim that the reason why kinds are prized by science is that they enter into a variety of different empirical generalizations. Nevertheless, I show that this tension ceases in the case of ‘cultural homologues’—such as specific ideologies, religions, and folk wisdom. I argue that the instances of such special science kinds do have several projectable properties in common due to their shared history of reproduction, and that the social learning involved means that we should also expect these kinds to be multiply realized.
