Spider Coming Down

The Hopi Indians regard humor, even sexual humor, as a form of prayer in their religious ceremonies. Clowns play an important role among the kachinas, twisting things around to make important points.     

Rising Up From Down Under: A Response To Adams-Webber On Cognitive Psychology And Personal Construct Theory

This article is a response to Adams-Webber's (1990) critique of my discussion of the relation between personal construct theory and cognitive psychology (Warren, 7990). Several points of specific disagreement are raised in an effort to clarify my own position. Furthermore, this clarification highlights the need for “integrationist” perspectives to clearly and directly address the problems, as well as the prospects, of relating personal construct theory to other perspectives in psychology.     

Laying Down Hume's Law

Most interpretations of Hume's is/ought passage (THN 3.1.1.27) can be broadly divided into two camps: those thinking Hume to rule out logical inferences from is to ought, and those thinking Hume to only raise surmountable difficulties for inferences from is to ought. I undermine the positive support for both these interpretations, and argue, by drawing parallels with Hume's argument on induction, that Hume's Law instead rules out all forms of inference from is to ought.     

Down with the Hierarchies

Evidence hierarchies are widely used to assess evidence in systematic reviews of medical studies. I give several arguments against the use of evidence hierarchies. The problems with evidence hierarchies are numerous, and include methodological shortcomings, philosophical problems, and formal constraints. I argue that medical science should not employ evidence hierarchies, including even the latest and most-sophisticated of such hierarchies.     

The Body Stripped Down

Abstract— According to terror management theory, cultural beliefs and standards provide protection from fears associated with mortality by convincing individuals that their existence matters more than that of any mere mortal animal. The body threatens the efficacy of such mechanisms by reminding us that we are animals nonetheless, and therefore fated to death. I present research demonstrating that existential concerns contribute to uneasiness with the body, especially regarding sex, and also to pervasive concerns with how the body measures up to cultural standards, most obviously regarding women's appearance. These findings show that in effort to defend against threats associated with the body's physicality, people may deny themselves pleasure and endanger their health.     

Epidemiology of Down syndrome

Down syndrome (DS) is the most commonly identified genetic form of mental retardation and the leading cause of specific birth defects and medical conditions. Traditional epidemiological studies to determine the prevalence, cause, and clinical significance of the syndrome have been conducted over the last 100 years. DS has been estimated to occur in approximately 1 in 732 infants in the United States, although there is some evidence that variability in prevalence of estimates exist among racial/ethnic groups. Progress has been made in characterizing the specific types of chromosome errors that lead to DS and in identifying associated factors that increase the risk of chromosome 21 malsegregation, i.e., advanced maternal age and recombination. Studies to examine the variability of the presence of specific DS-associated birth defects and medical conditions provide evidence for genetic and environmental modifiers. Here, we provide a brief survey of studies that address the current state of the field and suggest gaps in research that can soon be filled with new multidisciplinary approaches and technological advances.     

Gender Differences in Intercepting a Moving Target by Using a Throw or Button Press

Humans are a throwing species just as much as a talking species (Calvin, 1982), but preadaptations for throwing remain largely unexplored. The ability of undergraduate students (N = 165) to intercept a stimulus with a thrown object was determined for 10 stimulus speeds, ranging from 2 to 5 m/s. The inclusion of a condition in which the moving stimulus was intercepted via button press allowed the role of the perceptual aspect of velocity estimation to be evaluated separately from the act of throwing. Gender differences were observed in both the button and the throwing intercept tasks: The men had smaller timing errors and higher accuracy than the women. Contrary to expectations, the male and female patterns of intercept errors as a function of stimulus speed were more similar in the throwing task than in the button intercept task.

Second-order Equality and Levelling Down

Many think that equality is an intrinsic value. However, this view, especially when based on a consequential foundation, faces familiar objections related to the claim that equality is sometimes good for none and bad for some: most notably the levelling down objection. This article explores a unique (consequential) conception of equality, as part of a more general conception of fairness concerning the resolution of interpersonal conflicts, which is not exposed to these objections.     

Down syndrome: cognitive phenotype

Down syndrome is the most prevalent cause of intellectual impairment associated with a genetic anomaly, in this case, trisomy of chromosome 21. It affects both physical and cognitive development and produces a characteristic phenotype, although affected individuals vary considerably with respect to severity of specific impairments. Studies focusing on the cognitive characteristics of Down syndrome were reviewed, and while performance in most areas could be predicted based upon overall intellectual disability, relative weaknesses were consistently found to be associated with expressive language, syntactic/morphosyntactic processing, and verbal working memory. This profile of uneven deficits could result from a failure to develop typically automatic processing for speech perception and production, and this possibility is discussed along with its implications for intervention.     

How to Throw a Pot: The Centrality of the Potter's Wheel in the Zhuangzi

This article explains Zhuangzi's philosophy by analyzing the metaphor of the potter's wheel. I argue that this is one of the central images in the core chapters of the Zhuangzi. Together with two cognate images, it not only appears in some crucial passages, but also allows us to integrate a variety of seemingly independent topics. The article consists of four sections. I start by placing the potter's wheel against a background of other artisan tools. A second section focuses on three major themes revolving around the image of the potter's wheel in the Zhuangzi: stillness of mind, flexibility in response, and harmonizing and living out one's years. A third section discusses the negative portrayal of measurement tools in the Zhuangzi. In an afterword, I summarize the findings and revisit some methodological issues. The study shows that concrete images such as artisan tools may provide important clues for interpreting philosophical texts.
