Reversed better-than-average effect in direct comparisons of nonsocial stimuli depends on the set size

Studies on direct comparative judgments typically show that, for items that are positively evaluated, a single item randomly drawn from a larger set of similar items tends to be judged as better than average (the BTA effect). However, Windschitl, Conybeare, and Krizan (2008) demonstrated that, under timing conditions that do not favor focusing attention on the single item, the reversal of the BTA effect occurs. We report two experiments showing that the magnitude of the reversed BTA effect increases as a function of the size of a multiitem referent with which a single item target is compared. Specifically, in direct comparative judgments of the attractiveness of positively evaluated objects (nice-looking cloth buttons, attractive buildings, or cupcakes), underestimation of the attractiveness of singletons, as compared with a multiitem set (reversed BTA effect), increased with the increased set size. Analysis of absolute judgments obtained for singletons and for small and large multiitem sets suggests that, for attractive stimuli, both the reversed BTA effect in comparative judgments and its sensitivity to set size occur as a result of a positive relationship between set size and perceived attractiveness in absolute judgments.     

Escaping the World: Linguistic Indicators of Suicide Attempts in Poets

The purpose of this study was to determine features of language use in the texts of poets who committed suicide and to identify psychological factors contributing to depression and suicide. Texts of suicidal and non-suicidal poets were analyzed via the Linguistic Inquiry and Word Count program. ANOVA and logistic regression analysis revealed predictors of suicide: higher percentage of words self-oriented, expressed negative emotions, ambiguity, exclusion attitude toward reality, and lower percentages of words related to others, world entitativity, and experiencing the world. The data support hypotheses that suicide is facilitated by weak social bonds, egocentrism, helplessness, and visions of an unordered, uncertain, and unsafe world.     

The living state,evolution and consciousness

The purpose of the paper is to discuss the phenomenon of life through the aspect of consciousness and in particular to analyze the role which consciousness plays in the living state (the L‐state for short) as well as the consequences of the development of consciousness for the evolution of living beings. Consciousness is an epiphenomenon of knowledge. The discussion of the role of consciousness in life will have to involve an elucidation of the role of knowledge. This will be done in light of and using the ideas of the theory of the Ecology of Knowledge developed by the author (Wojciechowski, 1975, 1986, 1989).

Because of the special nature of consciousness, the paper will deal with the methodological problems of the study of consciousness, and, therefore of the study of the living state.     

Motor Performance in the Third,Not the Second Month,Predicts Further Motor Development

ABSTRACT. The aim was to verify if motor performance at second or third month of life better predicts further development. The global motor development was assessed by a neurologist and by a physiotherapist in 111 children at 2, 3, 6, and 9 months. At 2 and 3 months a physiotherapist also performed the assessment of qualitative elements. The physiotherapeutic assessment in the third month showed higher compatibility with the neurological assessment. Proper motor performance at third month could ensure the level of at least 7 months in the ninth month of life. Qualitative score above 7 of 15 points in the third month ensured proper development in ninth month. Third month of life is a better predictor of further motor development.     

Weak Interactions: Asymmetry of Time or Asymmetry in Time?

The paper analyzes the philosophical consequences of the recent discovery of direct violations of the time–reversal symmetry of weak interactions. It shows that although we have here an important case of the time asymmetry of one of the fundamental physical forces which could have had a great impact on the form of our world with an excess of matter over antimatter, this asymmetry cannot be treated as the asymmetry of time itself but rather as an asymmetry of some specific physical process in time. The paper also analyzes the consequences of the new discovery for the general problem of the possible connections between direction (arrow) of time and time-asymmetric laws of nature. These problems are analyzed in the context of Horwich’s Asymmetries in time: problems in the philosophy of science (1987) argumentation, trying to show that existence of a time–asymmetric law of nature is a sufficient condition for time to be anisotropic. Instead of Horwich’s sufficient condition for anisotropy of time, it is stressed that for a theory of asymmetry of time to be acceptable it should explain all fundamental time asymmetries: the asymmetry of traces, the asymmetry of causation (which holds although the electrodynamic, strong and gravitational interactions are invariant under time reversal), and the asymmetry between the fixed past and open future. It is so because the problem of the direction of time has originated from our attempts to understand these asymmetries and every plausible theory of the direction of time should explain them.
