Roy Sorensen has argued that a certain technical use of quotation marks to name the empty string supports a revised version
of Davidson’s theory of quotation. I point out that Sorensen’s considerations provide no support for Davidson’s original theory,
and I show that at best they support the revised Davidsonian theory only to the same extent that they support a simpler revised
version of a Tarskian theory. 相似文献

Heuristics and cognitive biases can occur in reasoning and decision making. Some of them are very common in gamblers (illusion of control, representativeness, availability, etc.). Structural characteristics and functioning of games of chance favor the appearance of these biases. Two experiments were conducted with nonpathological gamblers. The first experiment was a game of dice with wagers. In the second experiment, the participants played two bingo games. Specific rules of the games favored the appearance of cognitive bias (illusion of control) and heuristics (representativeness and availability) and influence on the bets. Results and implications for gambling are discussed. 相似文献

Daniel Ellsberg presented in Ellsberg (The Quarterly Journal of Economics 75:643–669, 1961) various examples questioning the
thesis that decision making under uncertainty can be reduced to decision making under risk. These examples constitute one
of the main challenges to the received view on the foundations of decision theory offered by Leonard Savage in Savage (1972).
Craig Fox and Amos Tversky have, nevertheless, offered an indirect defense of Savage. They provided in Fox and Tversky (1995)
an explanation of Ellsberg’s two-color problem in terms of a psychological effect: ambiguity aversion. The ‘comparative ignorance’ hypothesis articulates how this effect works and explains why it is important to an understanding
of the typical pattern of responses associated with Ellsberg’s two-color problem. In the first part of this article we challenge
Fox and Tversky’s explanation. We present first an experiment that extends Ellsberg’s two-color problem where certain predictions
of the comparative ignorance hypothesis are not confirmed. In addition the hypothesis seems unable to explain how the subjects
resolve trade-offs between security and expected pay-off when vagueness is present. Ellsberg offered an explanation of the
typical behavior elicited by his examples in terms of these trade-offs and in section three we offer a model of Ellsberg’s
trade-offs. The model takes seriously the role of imprecise probabilities in explaining Ellsberg’s phenomenon. The so-called
three-color problem was also considered in Fox and Tversky (1995). We argue that Fox and Tversky’s analysis of this case breaks
a symmetry with their analysis of the two-color problem. We propose a unified treatment of both problems and we present a
experiment that confirms our hypothesis. 相似文献

Internal sets and the Boolean algebras of the collection of the internal sets are of central importance in non-standard analysis.
Boolean algebras are the algebraization of propositional logic while the logic applied in non-standard analysis (in non-standard
stochastics) is the first order or the higher order logic (type theory). We present here a first order logic algebraization
for the collection of internal sets rather than the Boolean one. Further, we define an unusual probability on this algebraization. 相似文献

The metallic glass Pd40Cu30Ni10P20 in as-cast or pre-annealed states was shot-peened successively at room temperature or at 77 K. The structural state of the glass was characterized by the relaxation spectrum measured in a differential scanning calorimeter. Mechanically induced relaxation of the as-cast glass and mechanically induced rejuvenation of pre-annealed samples are both more evident at 77 K than at 298 K, enabling deductions about the underlying mechanisms. The relaxation spectrum of the glass as a function of temperature displays two broad maxima, which occurring at the higher temperature is attributed to the part of the free-volume distribution associated with flow defects. In samples shot-peened at 77 K, the stored energy after deformation can be as high as 20% of the cold work. Shot-peening simultaneously generates flow defects within shear bands and destroys them in the matrix between bands: whose effect dominates is principally dependent on the initial state of relaxation of the glass. Shot-peening of partially crystallized samples appears capable of breaking up and dispersing crystallites without inducing any further significant crystallization. 相似文献

This study empirically tested the predictions of the three basic perspectives on the bandwidth debate about the relationship between personality and job performance, regarding the validity of conscientiousness and its facets. The sample consisted of 226 police officers. Conscientiousness and three facets (order, industriousness, and self‐control) were correlated with three performance criteria (overall job performance, task performance, and orderliness). A Schmid–Leiman transformation made it possible to residualize the variance of the facets and to isolate their unique contribution to the prediction of performance measures. The results showed that conscientiousness predicted the three criteria (true validities of.25,.28 and.37, respectively) and that the facets neither predicted job performance nor showed incremental validity over conscientiousness. Finally, the implications of the findings for theory and practice are commented on, and future research is suggested. 相似文献

This paper studies children’s capacity to understand that the emotions displayed in pretend play contexts do not necessarily correspond to internal emotions, and that pretend emotions may create false beliefs in an observer. A new approach is taken by asking children about pretend emotions in terms of pretence-reality instead of appearance-reality. A total of 37 four-year-olds and 33 six-year-olds were asked to participate in tasks where they had to pretend an emotion or where they were told stories in which the protagonists pretended an emotion. In each task children were asked: a) if the pretend emotion was real or just pretended and b) if an observer would think that the emotional expression was real or just pretended. Results showed that four-year-olds are capable of understanding that pretend emotions are not necessarily real. Overall, six-year-olds performed better than younger children. Furthermore, both age groups showed difficulty in understanding that pretend emotions might unintentionally mislead an observer. Results are discussed in relation to previous research on children’s ability to understand pretend play and the emotional appearance-reality distinction. 相似文献

We aim to analyze the effects of an 8-month physical activity intervention on cardiorespiratory fitness, body mass index (BMI), and vigilance performance in an adult obese population. We conducted an 8-month physical activity intervention based on dance and rhythmic activities. The weekly frequency was 2 sessions of 1 hr per day. Training sessions were divided into 3 phases: a 10-min warm-up, 40 min of dance and rhythmic activities, and 10 min to cool-down. To assess cardiorespiratory fitness, participants performed a modified version of the 6-min walk test from the Senior Fitness Test battery (Larsson & Mattsson, 2001; Rikli & Jones, 1999). Vigilance performance was measured by means of the psychomotor vigilance task (PVT). Two measurements were performed immediately before and after the intervention. The results revealed that participants improved their cardiorespiratory fitness, BMI, and vigilance performance after the intervention. All in all, findings contribute new empirical evidence to the field that investigates the benefits of physical activity intervention on cognitive processes in obese population. 相似文献

This study is concerned with the definition of deviance and the processes of constructing deviance in Stalinist societies. Deviances created by the state in these societies are analyzed, especially from functionalist and phenomenologist aspects and by applying Foucault's approach. Solzhenitsyn's Gulag Archipelago is used as a starting point for the analysis. In his work, Solzhenitsyn dwells at length on the “deviances” and the process of deviance construction in Stalinist Soviet Union. It is suggested that, in these societies, “total state deviance” fits in a desacralized, demodernized world view. Finally some consequences of this deviance image still at work are discussed. 相似文献
