An experimental analysis of social traps

Social traps, such as the overgrazing of pasturelands, overpopulation, and the extinction of species, are situations where individuals in a group respond for their own advantage in a manner damaging to the group. A laboratory analog was devised to simulate conditions that produce social traps. The traps were constructed by superimposing schedules of reinforcement. Single responses were followed by multiple consequences which were opposite in valence, with the negative consequence delayed. Subjects in groups of three could respond individually for points that applied toward class credit. Each ten presses of a button added one point to the subject's total and subtracted one point from a common pool. The pool was replenished with points at fixed rates. If subjects responded for points faster than the replenishment rates, the pool would empty and the experiment would terminate before subjects could accumulate maximum credit. In addition, the maximum pool size and the ability to communicate were varied. Main effects were found for both, which indicated the least effective resource management occurred when the pool was small and no communication allowed. An analysis of cumulative records showed differing response patterns across conditions.     

SELECTIVE ASSOCIATIONS PRODUCED SOLELY WITH APPETITIVE CONTINGENCIES: THE STIMULUS-REINFORCER INTERACTION REVISITED

In studies reporting stimulus-reinforcer interactions in traditional conditioning paradigms, when a tone-light compound was associated with food the light gained stimulus control, but when the compound was paired with shock avoidance the tone gained control. However, the physical nature of the reinforcerrelated events (food vs. shock) presented in the presence of the tone-light compound was always confounded with the conditioned hedonic value of the compound's presence relative to its absence. When the compound was paired with shock, its presence was negative relative to its absence (which was shock-free). In contrast, when the compound was paired with food, its presence was positive relative to its absence (which was food-free). The present experiment dealt with this confounding effect by conditioning a tone-light compound to be positive or negative, relative to its absence, solely with food reinforcement. One group of rats received food for responding in the presence of the tone-light compound and no food in its absence. The other group also responded in the presence of the compound, but received food only in its absence. These rats were trained on a chained schedule in which responding in the presence of the tone-light compound produced a terminal link signaled by the absence of the compound; responding ceased in the terminal link because it delayed food delivery. In a test session to assess stimulus control by the elements of the compound, tone and light were presented separately under extinction conditions. Rats that had been exposed to a positive correlation between food and the compound emitted almost double the responses in the presence of the light as in the presence of the tone. In comparison, rats that had been exposed to a negative correlation emitted only two thirds as many responses in the presence of the light as in the presence of the tone. Because this selective association was produced using only food, it appears that the contingencies under which a reinforcer is presented, rather than (or as well as) its physical properties, can generate the selective associations previously attributed to “stimulus-reinforcer interactions.” This could mean that regardless of the class of reinforcer that ultimately maintains responding (appetitive or aversive), the contingency-generated hedonic value of the compound stimulus may influence the dominant modality of stimulus control.     

Soul,Myth and Cosmovision in a Changing World: Essentials of Analytical Psychology and the Descendent Path1

This essay addresses the key role of analytical psychology amid our changing world: to work towards an expansion of Humanity's worldview. In current times of utmost transformation, it becomes imperative that we embrace a total cosmovision, one that includes the 360 degrees of existence: not only the 180 diurnal degrees of ascent, light and order, yet also the descendent sphere, incorporating what is unconscious, nocturnal and mysterious. Integrating this lower realm in our psychic life, however, contrasts our Western worldview, in which these two domains are seemingly opposed and mutually excluding. Mythopoetic language, and the mythologems that manifest in different myths, provide the means of delving into the profound paradoxes at the core of the total cosmovision. Myths such as Añañuca (Chile), Osiris (Egypt), Dionysus (Greece) and Innana (Sumer), highlight the descending path, providing a symbolic narrative of an archetypical transformation or spin, a key moment of “turning on its own axis” that merges the realms of Life and Death, ascent and descent, birth and decay. To live this paradoxical and generative path of transformation, individuals must seek their personal myth not outside but within themselves, where springs the Suprasense.     

Sexuality as an Integral Part of the Church's Being and Mission

The article draws on the experience of being part of the Reference Group on Human Sexuality and other debates on sexuality in the World Council of Churches to discuss the “Message of the 11th Assembly.” It makes explicit how issues of sexuality have been avoided and how they ground the understanding of theological perspectives and the church's being and mission. Finally, it presents alternatives to reclaim sexuality and make the movement of reconciliation grounded in a transformative and queer spirituality more concrete and truthful to people's lives – a sexy movement.     

春秋战国齐金文字体研究

春秋战国是汉字字体由篆到隶的重要时期,齐金文素以其精严整饬的美化藻饰体著称,但这只是其字体演变中的一个环节。齐金文字体演变在书写便捷的原动力下,通过体势趋扁趋方打破篆体长圆体势,通过短直的笔画分解篆体圆转的笔画,与其他地域的金文字体一起推动了汉字字体的演变,并以其鲜明的地域个性丰富了汉字字体面貌。     

《序卦》研究辨析

本文就唐宋以来对通行本《序卦》的义理与象数两个方面的研究进行了综述,对各种研究的结果进行了考辨。并在前人研究的基础上提出了个人的看法,指出似乎从当时《易经》成书及揲蓍变卦等方面考虑《序卦》之卦序安排,则可能会得到令人信服的结果。     

时间定价与主观时间流逝速度感对利他行为的影响

采用筛选图片时间任务作为被试利他意愿的指标,考察在两种主观时间流逝速度（时间飞逝和时间缓慢）条件下,被试（时间定价组和非时间定价组）对利他行为的影响。结果发现,非时间定价组在时间飞逝和缓慢条件下利他行为差异不显著,但是时间定价组在时间飞逝条件下比在时间缓慢条件下利他行为时间明显较短。结果表明,时间定价组在时间飞逝条件下充分显现时间的价值,减少利他时间,而在时间缓慢条件下,在可接受的时间成本范围内,被试表现出较为乐于助人,证实了主观时间流逝速度会对个体利他行为产生影响。     

外在特征变化对人像辨认的影响

运用眼动分析法探讨了外在特征变化对人像辨认的影响,即外在特征多少、学习与辨认外在特征的一致性对人像辨认的影响。因变量为人像辨认的反应时、辨别力、注视次数、眼跳幅度。实验表明：学习与辨认的一致性对人像辨认影响显著,外在特征多少对人像辨认影响不显著。     

Le mathème du fantasme à l'adolescence

In Lacan's writing the matheme is a logical construction aiming to correspond to the bone structure of the subject. In what respect can the formalization of fantasy enlighten us as regards the adolescent “passage”? Is this passage from child neurosis to the adolescent period accompanied by a different positioning in fantasy? This is the assumption which will be illustrated and defended with clinical cases. Fantasy is logically constructed. The matheme unite and separate through the awl, the two sides of the subject: the “barred subject” and the “object a”. The recasting of fantasy at adolescence will consist in revisiting the three terms while gauging the worth of the link-break operation which is the awl.
