Asymmetry arguments

In the First Meditation, the Cartesian meditator temporarily concludes that he cannot know anything, because he cannot discriminate dreaming from waking while he is dreaming. To resist the meditator’s conclusion, one could deploy an asymmetry argument. Following Bernard Williams (1978), one could argue that even if the meditator cannot discriminate dreaming from waking while dreaming, it does not follow that he cannot do it while awake. In general, asymmetry arguments seek to identify an asymmetry between a bad case that is entertained as a ground for doubt and a good case in which one takes oneself to know something. My aim in this paper is to consider how effective asymmetry arguments are as an anti-skeptical strategy. I conclude that although asymmetry arguments provide an effective response to dreaming skepticism, they fail as a response to brains-in-a-vat skepticism.     

Body mass index and waist: hip ratio are not enough to characterise female attractiveness

The assessment of characteristic body features of Miss Poland beauty contest finalists compared with the control group, can contribute to recognising the contemporary ideal of beauty promoted by the mass media. The studies of Playboy models and fashion models conducted so far have been limited to the following determinants of attractiveness: body mass index, waist:hip ratio, and waist:chest ratio, which only partially describe the body shape. We compared 20 body features of the finalists of Miss Poland 2004 beauty contest with those of the students of Medical Academy in Bydgoszcz. Discriminant analysis showed that the thigh girth-height index, waist: chest ratio, height, and body mass index had the greatest discrimination power distinguishing the two groups. A model of Miss Poland finalists figure assessment is presented which allows one to distinguish super-attractive women from the control group.     

Rumination as a common mechanism relating depressive risk factors to depression

Rumination was examined as a potential common mechanism linking risk factors with depression. Initially nondepressed individuals (N = 137) were assessed for presence of a ruminative response style and 4 other hypothesized risk factors for depression. They were followed for 2.5 years. Negative cognitive styles, self-criticism, dependency, neediness, and history of past depression were all significantly associated with rumination. Rumination mediated the predictive relationships of all risk factors except dependency with the number of prospective Diagnostic and Statistical Manual of Mental Disorders (3rd ed., rev.; American Psychiatric Association, 1987) major depressive episodes (MDEs; definite and subthreshold) during the follow-up period. In contrast, private self-consciousness did not mediate any relationships between risk factors and subsequent MDEs. Thus, rumination, as a special kind of self-focus, may act as a general proximal mechanism through which other vulnerability factors affect depression.     

Family Therapy in Poland: Development and Current Perspectives

The authors of the present article describe the historical context of family therapy in Poland and current issues in the field. They highlight the fact that Polish therapists first began to develop the field after coming into contact with family therapy leaders from the United States and Western Europe. With the political breakthrough of 1989, there were new opportunities for multilateral cooperation, attendance at international conferences, and the exchange of experiences. Currently, the work of Polish family therapists, the place of family therapy among other forms of psychotherapy, and the related problems and challenges do not differ from other European nations.     

Intra- and inter-judge reliabilities in measuring the skin-fold thicknesses of ultra runners under field conditions

Inter- and intra-judge reliabilities of skinfold measures were investigated in a sample of 27 men and 11 women ultramarathon runners. Two physicians had agreement higher than 90% in field measurements before an ultramarathon race.     

Astrophysical Fine Tuning,Naturalism, and the Contemporary Design Argument

Evidence for instances of astrophysical ‘fine tuning’ (or ‘coincidences’) is thought by some to lend support to the design argument (i.e. the argument that our universe has been designed by some deity). We assess some of the relevant empirical and conceptual issues. We argue that astrophysical fine tuning calls for some explanation, but this explanation need not appeal to the design argument. A clear and strict separation of the issue of anthropic fine tuning on one hand and any form of Eddingtonian numerology and teleology on the other, may help clarify arguably the most significant issue in the philosophy of cosmology.     

They do what they are told to do: the influence of instruction on (chess) expert perception-commentary on linhares and brum (2007)

Linhares and Brum (2007) argue that they provide evidence for analogy as the main principle behind experts' acquisition of perceptual knowledge. However, the methodology they used—asking players to pair positions using abstract similarity—raises the possibility that the task reflects more the effect of directional instructions than the principles underlying the acquisition of knowledge. Here we replicate and extend Linhares and Brum's experiment and show that the matching task they used is inadequate for drawing any conclusions about the nature of experts' perception. When expert chess players were instructed to match problems based on similarities at the abstract level (analogy), they produced more abstract pairs than pairs based on concrete similarity. However, the same experts produced more concrete pairs than abstract ones when instructed to match the problems based on concrete similarity. Asking experts to match problems using explicit instructions is not an appropriate way to show the importance of either analogy or similarity in the acquisition of expert knowledge. Experts simply do what they are told to do.
