GENERALIZATION BY AUTISTIC-TYPE CHILDREN OF VERBAL RESPONSES ACROSS SETTINGS

Generalization of verbal behavior by autistic-type children across physically different settings was assessed. Four boys learned responses to common questions in two settings at school and were probed to determine transfer of learning to home. Three of the children demonstrated little generalization to home when trained in a cubicle. Greater generalization was indicated when they received training at varied locations. The fourth child generalized most responses to his home regardless of training setting. Simple manipulations of the school environment to more closely simulate home conditions may facilitate transfer of training to the natural environment.     

Kant: The Audacity of Judgement

In the legal judgement reason demands that it extend itself beyond the mere subjective limits of the self in order that it might fashion a judgement that speaks for the other. This is the universal necessity of the judgement. No claim of truth or the moral law can guarantee that others will agree with this judgement: thus disputation is the risk which reason takes in order to judge at all. The author examines this audacity of judgement by reference to Kant's autonomy of reason, which risks itself in the thought that thinks. This revised version was published online in June 2006 with corrections to the Cover Date.     

The Biophilia Hypothesis and Life in the 21st Century: Increasing Mental Health or Increasing Pathology?

Wilson's biophilia hypothesis includes the claim that, as a consequence of evolution, humans have an innate tendency to focus on life and lifelike processes. A review of various literatures converges to support this central claim. One area of support for our innate affiliation with nature comes from research demonstrating increased psychological well-being upon exposure to natural features and environments. Support also comes from the strength and prevalence of phobic responses to stimuli of evolutionary significance and near absence of such responses to potentially dangerous human-made stimuli. That survival emotions of equivalent intensity and prevalence have failed to develop in response to modern life-threatening stimuli can be explained by the extremely rapid process of change and progress that has occurred post World War II and continues at an ever increasingly rapid pace. Given that our modern ways of living, as prescribed by Western industrialised culture, stand in stark contrast to our evolutionary history, it is proposed that we may currently be witnessing the beginnings of significant adverse outcomes for the human psyche.     

THE RELIGION OF A SCIENTIST: EXPLORATIONS INTO REALITY (RELIGIO PHILOSOPHI NATURALIS)

Abstract. Sir Thomas Browne's reflection on the synthesis between his Christian religion and his practice as a medical doctor, made over three centuries ago, leads into reflections on the present relation between religion and science in the personal experience of the writer. An account is given of how the actual practice of scientific investigation led the author to theistic inferences and how the study of DNA provoked questions concerning reductionism and emergence. This evoked the need for a map of knowledge, and an attempt is presented in a figure which also serves to clarify what kind of realistic reference is involved in both scientific and humanistic contexts–especially with respect to personal language. Theological investigations thereby receive at least provisional legitimization and, with this encouragement, the article pursues the questions of the nature of the divine Source ("God") of the world's being and becoming, of God's interaction and communication with the world, especially with human beings in that world. The penultimate section outlines why the writer considers an explicit communication from God to humanity in Jesus of Nazareth is coherent with the foregoing and what this implies for human fulfillment, individually and corporately. The article concludes with a plea for humility before God and nature in our inquiries in the spirit both of Sir Thomas Browne and of the arch "agnostic" T. H. Huxley.     

Motion as a natural category for pigeons: Generalization and a feature-positive effect

Three groups of pigeons were trained with a modified discriminative autoshaping procedure to discriminate video images of other pigeons on the basis of movement. Birds of all groups were shown the same video images of other pigeons, which were either moving or still. The group to whom food was presented only after moving images learned the discrimination very quickly. A second group, to whom food was given only after still images, and a pseudocategory group, to whom food was presented after arbitrarily chosen stimuli, showed no evidence of discrimination during acquisition training. Extinction conditions led to clear differences in peck rates to moving and still images in the second group but not in the pseudocategory group. The result is related to the feature-positive effect. Generalization tests showed that the discrimination performance was based on visual features of the stimuli but was invariant against changes of size, perspective, brightness, and color. Furthermore, discrimination was maintained when novel images of pigeons under different viewing angles and seven other types of motion categories were presented. It is argued that the discrimination is based not on a common motion feature but on motion concepts or high-order generalization across motion categories.     

The skillful means and meanings of philosophy: Attention and immersion in the philosophical art of writing

This response to Richard Shusterman's Philosophy and the Art of Writing focuses on his concern that philosophy is, first and foremost, a way of life, illustrated in the West by the Socratic ideal of the philosopher and in the East by the example of the scholar-artist-gentleman. This paper examines the process of Buddhist meditation and the process of creating novels, supplementing the authors Shusterman carefully examines with examples from Black American literature, the author's own teacher John Gardner, and artistic colleagues the author has known. The basic thrust of the response is that the skillful means used in writing can indeed be a form of self-creation, but it can also be a means of liberation from the self.     

Meaning and beauty

What place do experiences of beauty have in a meaningful life? A marginal one, at best, it would seem, if one looks at the current literature in analytic philosophy. Treatments of beauty within so-called “analytic existentialism” tend to suffer from four limitations: beauty is neglected, reduced to artistic production, saddled to theology, or taken as a mere application of a broader theoretical framework. These discussions fail to engage with the rich tradition of philosophical aesthetics. In this essay, I begin by responding to the contention that experiences of beauty cannot lend life meaning because they are passive. Drawing on work in philosophical aesthetics, I then argue that encounters with the beautiful count as genuinely meaning-conferring because they have features commonly taken as marks of meaningfulness.     

NATURALISM AND THE CATEGORIES “SCIENCE” AND “RELIGION”: A RESPONSE TO JOSH REEVES

This article is a response to Josh Reeve's “A Defense of Science and Religion.” I begin with the disclaimer that this was not solely my project but a joint enterprise. A common commitment of participants was to make the disciplines of history and theology central to the discussion and explore what new possibilities follows for the field of science and religion. I then address Reeves's two central concerns: first that I am too dismissive of the categories “science” and “religion.” In fact I have not advocated dispensing with these categories, but have insisted than we employ them critically and with a sense of their history. The second concern is that my position on naturalism seems to place me perilously close to advocates of ID or scientific creationism. I deny this, but point out that more work needs to be done, beyond simply invoking methodological naturalism, to clarify the differences between naturalistic and theological approaches to the world.     

面孔审美加工的神经机制及个体差异

外显和内隐的面孔审美加工的脑成像研究表明,美的面孔比不美的面孔导致眶额皮层、伏隔核、杏仁核等奖赏脑区更大的激活。脑电研究则发现了与面孔审美加工有关的早期负波和晚期正成分。面孔审美加工有关的脑区活动也受到性别、生理周期等个体因素的调节。未来的研究需要比较美的面孔与其它奖赏刺激加工的神经机制,探讨面孔审美加工的不同阶段及时间进程,在面孔知觉的框架下形成合理的面孔审美加工的神经模型。
