Knowledge and Error in Early Chinese Thought

Drawing primarily on the Mòzǐ and Xúnzǐ, the article proposes an account of how knowledge and error are understood in classical Chinese epistemology and applies it to explain the absence of a skeptical argument from illusion in early Chinese thought. Arguments from illusion are associated with a representational conception of mind and knowledge, which allows the possibility of a comprehensive or persistent gap between appearance and reality. By contrast, early Chinese thinkers understand mind and knowledge primarily in terms of competence or ability, not representation. Cognitive error amounts to a form of incompetence. Error is not explained as a failure to accurately represent the mind-independent reality due to misleading or illusory appearances. Instead, it can be explained metaphorically by appeal to part-whole relations: cognitive error typically occurs when agents incompetently respond to only part of their situation, rather than the whole.     

The factorial structure of sleep dissatisfaction

Research into sleep problems has been dominated by a number of theoretical perspectives from each of which useful treatment applications have been derived. However, the rich diversity of problems that are subsumed under insomnia or sleep disturbance often remain unappreciated. This paper reports the results of a factor analysis performed on the combined items of two questionnaires designed to assess sleep disturbance. Six factors are described, two of which relate to cognitive aspects of sleep disturbance; two which map onto sleep onset and sleep maintenance problems; and two which are drawn from dissatisfaction with poor sleep. Correlations of factor scores with measures of neuroticism, worry and various sleep history variables provide a strong level of construct validity. The results are discussed in terms of their treatment implications.     

Gender Differences in Sado-Masochistic Arousal Among College Students

This paper tests three competing explanationsfor male-female differences in sado-masochistic sexualarousal. The male arousal hypothesis posits that becauseof socialization that emphasizes sexual aggression and experimentation (and thus higher levels ofsexual arousal and activity in all areas), men will bemore aroused by both sadism and masochism than women.The female masochism hypothesis argues that because females are socialized to be passive, they willbe more aroused by masochistic (but not sadistic)activities than males. The convergence hypothesis notesthat male female socialization (and differences in most sexual attitudes and behavior) haveconverged in recent years, and hypothesizes that thesame convergence has taken place in arousal caused bysado-masochistic behavior and fantasy. Using a sample comprised of 320 undergraduate students (69%white, 27% African American, 4% other) from a largeurban university in the Southeast, we found no evidencefor the female masochism hypothesis and only weak evidence for the convergence hypothesis. Thestrongest evidence was for the male arousal hypotheses,with males scoring significantly higher than females onseven of the twelve measures of sado-masochistic arousal, and no differently from females on theremaining five.     

Cognitive strategies in coping with expedition stress

Expeditions provide a valuable opportunity for studying processes of coping with a stressful situation. An expedition to India organized by the British Schools Exploring Society has already been reported as being accompanied by positive changes on self-report personality scales. This paper is concerned with detailed cognitive coping measures completed throughout the 6 weeks of the expedition. It needs to be noted that the results relate to young adults and to those who provided detailed coping information; the generalizability of the result is a matter for future research. The expedition presented a mixture of physical and social stresses. Men enjoyed the physical experience more than women, but women enjoyed the social experience more than men. There was generally greater reliance on personal resources than on social support in coping with stress. This was particularly true for men in coping with physical stress and women in coping with social stress. In general, the physical stresses had been better anticipated than the social ones. Positive reformulations were much more widely used as coping strategies than avoidance/resignation strategies, especially so for physical stresses. However, use of avoidance/resignation strategies was the better predictor of outcome, with those who used them being least likely to show positive personality change as a result of the expedition. The results are related to current research on stress and coping.     

Multicriteria approval: application of approval voting concepts to MCDM problems

Multicriteria decision making (MCDM) methods generally require information that is difficult and expensive to obtain. It is shown in this paper that given an ordering of criteria by importance, and whether each alternative is above the average evaluation of the alternatives for each criterion, considerable information can be extracted concerning the overall rankings of the alternatives. This is done by recognizing the similarity between criteria in MCDM, and voters in social choice theory. Multicriteria approval, proposed in this paper, is an MCDM adaptation of approval voting which can be used to classify decisions into one of several categories, depending on whether, and the manner in which, a superior alternative can be identified. An exhaustive examination of all possible decision situations of tractable size is made to measure the applicability of multicriteria approval, and the approach is demonstrated in an industrial procurement case. In addition to requiring minimal information from a decision maker, multicriteria approval satisfies several desirable criteria for MCDM techniques. © 1998 John Wiley & Sons, Ltd.     

An automated food delivery system for behavioral and neurophysiological studies of learning and memory in freely moving monkeys

We describe a custom-built feeder based on stepping motor technology controlled by a laboratory computer. The feeder dispenses a wide range of foods: any fruit, vegetable, or nut. The feeder allows the investigator to reward monkeys with different foods within a single experimental day. The monkey’s motivation to perform tasks is high and does not rely upon food regulation. The avoidance of regulation, as well as the palatability and variety of the rewards dispensed by our device, distinguishes it from commercially available products. We also describe the use of the feeder in the context of novel behavioral and neurophysiological studies in freely moving monkeys.     

Religion and Partisanship in Canada

Using a survey of three thousand Canadian adults conducted by the Angus Reid Group in the autumn of 1996, we examine the continuing role of religion in shaping partisan preferences. We find that traditional religious alignments still have some impact, but are being reshaped by both religious and political developments. We find that Evangelical Protestants are drawn toward the new Reform Party, Mainline Protestants still tend toward the Progressive Conservatives, and Catholics—both English‐and French‐speaking—remain the bulwark of the Liberal Party. The New Democratic Party, however, finds its greatest resonance among secular Canadians, and the Bloc Quebecois is strongest among nominal, rather than practicing, French‐speaking Catholics. In multivariate analysis, these religious variables stand up well against other influences in explaining partisan preferences.     

The contribution of the thumb to reaching movements

Transport of the hand towards an object and the formation of grasp are logically separable components of reaching. It has been suggested that, although the two components must be temporally co-ordinated, their spatial parameters are under the control of independent visuo-motor channels. A case study of reaching by a proficient user of a manually-operated artificial hand is presented. A pattern of natural hand usage was observed in which the index finger rather than the thumb was responsible for reduction of grasp aperture as the hand approached an object. The same pattern of usage was also observed in the artificial hand even though the mechanics of that hand make it no easier to move the finger than the thumb. This suggests that the relative stability of the thumb in the natural hand is determined, not simply by anatomy, but by a role in guiding the transport component of reaching. At least part of the spatial aspect of grasp formation is closely related to the transport component of reaching and this is evidence against theories postulating two independent visuo-motor channels controlling the spatial parameters of grasp and transport.
