A dog at the keyboard: using arbitrary signs to communicate requests

As a consequence of domestication, dogs have a special readiness for communication with humans. We here investigate whether a dog might be able to acquire and consistently produce a set of arbitrary signs in her communication with humans, as was demonstrated in “linguistic” individuals of several species. A female mongrel dog was submitted to a training schedule in which, after basic command training and after acquiring the verbal labels of rewarding objects or activities, she learned to ask for such objects or activities by selecting lexigrams and pressing keys on a keyboard. Systematic records taken during spontaneous interaction with one of the experimenters showed that lexigrams were used in an appropriate, intentional way, in accordance with the immediate motivational context. The dog only utilized the keyboard in the experimenter’s presence and gazed to him more frequently after key pressing than before, an indication that lexigram use did have communicative content. Results suggest that dogs may be able to learn a conventional system of signs associated to specific objects and activities, functionally analogous to spontaneous soliciting behaviors and point to the potential fruitfulness of the keyboard/lexigram procedure for studying dog communication and cognition. This is the first report to systematically analyze the learning of arbitrary sign production in dogs.

Task-specific modulations of locomotor action parameters based on on-line visual information during collision avoidance with moving objects

The objectives of this study were: (a) to determine if the control mechanism for interacting with a dynamic real environment is the same as in the virtual reality (VR) studies, and (b) to identify the action control parameters that are modulated to successfully pass through oscillating doors. The participants walked along a 14-m path towards oscillating doors (rate of change in aperture size = 44 cm/s and maximum aperture varied 70, 80, or 100 cm). The participants had to use vision to extrapolate what the aperture of the doors would be at the time of crossing and determine if a change in action parameters was necessary. If their current state did not match the required state then the participants made modifications to their actions. The results showed that individuals in a real environment used similar action modifications (i.e., velocity adjustments) as those seen in VR studies to increase success. Aside from the gradual velocity adjustments observed, there was an immergence of a different locomotor action parameter on some trials that was not seen in VR studies (i.e., shoulder rotations). These shoulder rotations occurred when the participants perceived that a velocity adjustment alone would not lead to a successful trial. These results show that participants use perception to control movement in a feedback rather than feedforward manner.     

Trauma, forgiveness and the witnessing dance: making public spaces intimate

In this paper I explore the concept of forgiveness as a response to gross human rights violations. I present a conceptual examination of the effects of massive trauma in relation to what I refer to as the 'unfinished business' of trauma. Using a psychoanalytic framework, I consider the process of 'bearing witness' about trauma and examine how this process opens up the possibility of reciprocal expressions of empathy between victim and perpetrator. I then argue that, in this context of trauma testimony and witnessing, empathy is essential for the development of remorse on the part of perpetrators, and of forgiveness on the part of victims. Using a case study from South Africa's Truth and Reconciliation Commission (TRC) I clarify the relationship between empathy and forgiveness, and show how the restorative model of the TRC can open up an ethical space and create the possibility of transformation for victims, perpetrators and bystanders. In my conclusion I suggest that forgiveness in politics is the only action that holds promise for the repair of brokenness in post-conflict societies, particularly if, as in South Africa, victims have to live together with perpetrators and beneficiaries in the same country.     

A BIOLOGIST'S PERSPECTIVE ON THE FUTURE OF THE SCIENCE‐RELIGION DIALOGUE IN THE TWENTY‐FIRST CENTURY

In recent issues of Zygon, numerous reflections have been published commenting on where the field of science‐and‐religion has been, where it presently stands, and where it should move in the future. These reflections touch on the importance of the dialogue and raise questions as to what audience the dialogue addresses and whom it should address. Some scholars see the dialogue as prospering, while others point out that much work needs to be done to make the dialogue more accessible to a larger audience and more successful at tackling the provocative questions before us. Other academics view the questions themselves as needing further consideration and focus before answers to them can even be explored. In this article I provide a general overview of these essays by outlining some general categories of thought that seem to emerge from the contributors. I then present some of my own opinions concerning the future of the science‐religion field and emphasize that the dialogue, in addition to its traditional roles, must further the philosophical framework that can aid humanity in resolving the most pressing global concerns of our time.

中国人的人格特点(VI):人际关系

人际关系人格维度包括宽和与热情两个次级因素,反映的是对待人际关系的基本态度。该研究依据本土化的中国人人格量表对中国人的人际关系人格维度及其两个次级因素的特点进行了分析,发现个体的性别、年龄、职业和婚姻状况均对人际关系产生不同程度的影响。总体上看,女性比男性对人更宽和,男性比女性对人更热情;年龄越大,人际关系分数越高;行政管理者比工人农民与和教科文卫人员人际关系分数更高,而婚姻状况也与年龄和性别一起影响个体的人际关系倾向。     

罗杰斯与老子的人性观比较研究

西方人本主义理论的代表人物罗杰斯与道家的创始人老子的理论对人性的观点有很多相似之处,这种相似的人性观主要表现在他们对人的基本动机的理解之上,这两个基本动机分别为实现倾向性和复归倾向性。该文通过比较这两种基本动机,探讨罗杰斯与老子的人性观的相似点与不同点。     

Children’s spiritual development in forced displacement: a human rights perspective

This article provides a synthesis of current research and theories of spiritual development in forced displacement from a human rights perspective. Spirituality, understood as a cognitive‐cultural construct, has shown positive impact on children’s development through both collective and individual processes and across ecological domains of the physical world, the community and the individual child. Findings support a human rights framework of spiritual development that privileges the child’s and the community’s own understandings of human development, and this framework may further serve as an important resource for scaffolding refugee children’s development. The study of spiritual development will enable more effective human rights protection of child development in situations of war and forced displacement.     

Third party assisted conception: an African perspective

The central importance of reproduction in all human cultures has given rise to many methods and techniques of assisting reproduction or overcoming infertility. Such methods and techniques have achieved spectacular successes in the Western world, where processes like in vitro fertilization (IVF) constitute a remarkable breakthrough. In this paper, the author attempts to reflect critically on assisted reproduction technologies (ART) from the background and perspective of African culture, a culture within which human reproduction is given the highest priority but which also exhibits a highly ambivalent attitude to modern technology-assisted methods of reproduction. The author considers the ethical crux of reproductive technologies to be linked to the issue of the moral status of the human embryo and argues that a morally significant line of demarcation cannot be drawn between embryos and other categories of humans.     

The Great Apes and the Severely Disabled: Moral Status and Thick Evaluative Concepts

The literature of bioethics suffers from two serious problems. (1) Most authors are unable to take seriously both the rights of the great apes and of severely disabled human infants. Rationalism—moral status rests on rational capacities—wrongly assigns a higher moral status to the great apes than to all severely disabled human infants with less rational capacities than the great apes. Anthropocentrism—moral status depends on membership in the human species—falsely grants all humans a higher moral status than the great apes. Animalism—moral status is dependent on the ability to suffer—mistakenly equates the moral status of humans and most animals. (2) The concept person is widely used for justificatory purposes, but it seems that it cannot play such a role. It seems that it is either redundant or unable to play any justificatory role. I argue that we can solve the second problem by understanding person as a thick evaluative concept. This then enables us to justify assigning a higher moral status to the great apes than to simple animals: the great apes are persons. To solve the first problem, I argue that certain severely disabled infants have a higher moral status than the great apes because they are dependent upon human relationships for their well-being. Only very limited abilities are required for such relationships, and the question who is capable of them must be based on thick evaluative concepts. Thus, it turns out that to make progress in bioethics we must assign thick evaluative concepts a central role.
