SUBJECTIVISM,UTILITY, AND AUTONOMY

Taking as a starting point a thesis of David Gauthier's about the status of Rational Choice Theory. I discuss the relation between a subjectivist theory of value and an account of rational agency that leaves room for autonomy. I argue that if autonomy presupposes an activity of practical reason, the maximization of subjective expected utility (as prescribed by Rational Choice Theory) cannot serve as the principle of practical reason.     

The role of strategies in deciding advantageously in ambiguous and risky situations

In decision situations of everyday life, the potential positive or negative consequences of a decision are often specified and the associated probabilities are known or they are principally calculable ("decisions under risk"). On the basis of correlations reported in patient studies, it has been recently proposed that decisions under risk involve strategic components, i.e. calculation of the risk, as well as emotional processes, i.e. processing feedback from previous decisions. However, the potential impact of calculative strategies on decision-making under risk has not been investigated systematically, so far. In the current study, we examined 42 healthy subjects (21 females) with the Game of Dice Task measuring decisions under risk, and a questionnaire assessing strategy application in items comparable to the choices in the Game of Dice Task. In addition, the subjects performed the Iowa Gambling Task, examining decision-making under ambiguity, and a neuropsychological test battery focusing on executive functions. Results indicate that deciding advantageously in a decision-making task with explicit and stable rules is linked to applying calculative strategies. In contrast, individuals who decide intuitively prefer risky or disadvantageous choices in the Game of Dice Task. Applying calculative strategies was correlated with executive functions but not with performance on the Iowa Gambling Task. The results support the view that calculative processes and strategies may improve decision-making under explicit risk conditions.     

The Secret of My Success

In an information state where various agents have both factual knowledge and knowledge about each other, announcements can be made that change the state of information. Such informative announcements can have the curious property that they become false because they are announced. The most typical example of that is ‘fact p is true and you don’t know that’, after which you know that p, which entails the negation of the announcement formula. The announcement of such a formula in a given information state is called an unsuccessful update. A successful formula is a formula that always becomes common knowledge after being announced. Analysis of information systems and ‘philosophical puzzles’ reveals a growing number of dynamic phenomena that can be described or explained by unsuccessful updates. This increases our understanding of such philosophical problems. We also investigate the syntactic characterization of the successful formulas. An erratum to this article is available at .     

Beyond Recovery? a Reply to Tennant

In his paper ‘Changing the Theory of Theory Change: Reply to My Critics’, N. Tennant (1997b) reacts to the critical reception of an earlier article of his. The present note rectifies some of the most serious misrepresentations in Tennant's reply. This revised version was published online in July 2006 with corrections to the Cover Date.     

Different Types of Religious/Spiritual Well-Being in Relation to Personality and Subjective Well-Being

In this study the authors attempt to present different types of Religious/Spiritual Well-Being (RSWB) and discuss their relation to personality and psychological well-being. The Multidimensional Inventory for Religious/Spiritual Well-Being 48 is employed for this study, which consists of 6 subscales. To find different types of RSWB, an agglomerative cluster analysis on these subscales was performed based on the responses obtained in a nonclinical adult sample (n = 463). A 4-cluster solution was accepted. The clusters were labeled as Religious/Spiritual High, Religiously Oriented, Existentially Oriented, and Religious/Spiritual Low, and were found to be substantially related to Sense of Coherence (n = 263) and Six Factors of Personality (n = 200) in two different subsamples. By presenting a first empirical model for a 4-field typology of RSWB, we hope to further contribute to the ongoing discussion on how to deal with religious/spiritual issues in personality research.     

Evolutionary Psychology of Facial Attractiveness

The human face communicates an impressive number of visual signals. Although adults' ratings of facial attractiveness are consistent across studies, even cross-culturally, there has been considerable controversy surrounding attempts to identify the facial features that cause faces to be judged attractive or unattractive. Studies of physical attractiveness have attempted to identify the features that contribute to attractiveness by studying the relationships between attractiveness and (a) symmetry, (b) averageness, and (c) nonaverage sexually dimorphic features (hormone markers). Evolutionary psychology proposes that these characteristics all pertain to health, suggesting that humans have evolved to view certain features as attractive because they were displayed by healthy individuals. However, the question remains how single features that are considered attractive relate to each other, and if they form a single ornament that signals mate quality. Moreover, some researchers have recently explained attractiveness preferences in terms of individual differences that are predictable. This article briefly describes what is currently known from attractiveness research, reviews some recent advances, and suggests areas for future researchers' attention.
