JUDGEMENTS OF INTENTIONALITY AND MORAL WORTH: EXPERIMENTAL CHALLENGES TO HINDRIKS

Joshua Knobe found that people are more likely to describe an action as intentional if it has had a bad outcome than a good outcome, and to blame a bad outcome than to praise a good one. These asymmetries raised numerous questions about lay moral judgement. Frank Hindriks recently proposed that one acts intentionally if one fails to comply with a normative reason against performing the action, that moral praise requires appropriate motivation, whereas moral blame does not, and that these asymmetries are normal features of a theory of intentional action, not anomalies. I present two empirical studies revealing asymmetries in lay judgements of intentionality and moral blameworthiness; these cannot be explained by Hindriks' theory of intentional action.     

On Modal <Emphasis Type="Italic">μ</Emphasis>-Calculus and Gödel-Löb Logic

We show that the modal μ-calculus over GL collapses to the modal fragment by showing that the fixpoint formula is reached after two iterations and answer to a question posed by van Benthem in [4]. Further, we introduce the modal μ ^~-calculus by allowing fixpoint constructors for any formula where the fixpoint variable appears guarded but not necessarily positive and show that this calculus over GL collapses to the modal fragment, too. The latter result allows us a new proof of the de Jongh, Sambin Theorem and provides a simple algorithm to construct the fixpoint formula. Presented by Melvin Fitting     

Some Remarks on “Hearing-as” and its Role in the Aesthetics of Music

Starting from the context in which Wittgenstein thinks of the concepts of “seeing-as” and “hearing-as”, the basic relation is clarified between the question of representation, musical understanding, and the theory of musical expressiveness. The points of views of Wollheim, Scruton, Levinson, and Ridley are discussed, in a re-consideration of the notions of hearing and understanding within Wittgenstein’s “last philosophy”.     

Age-related Assessment of Postural Control Development: A Cross-sectional Study in Children and Adolescents

Abstract

The aim of this study was to outline an age-dependent range of posturography measures obtained from healthy children. One hundred and fifty healthy 4–18-year-old children underwent video Head Impulse Test and static posturography testing. Surface, length and power spectra values were compared between each group of pupils and 32 healthy adults. As well as a significant (p?<?0.025) increase in surface and length, when compared to healthy adults, increased values within the low/middle frequency domain and within the high frequency domain were also observed in 4–13 and 4–7-year-old children, respectively. In conclusion, although the nature of postural control development remains largely undetermined, this study represents a first attempt to outline an age-dependent normal range of the relative contribution of inputs in typically developing children.     

Self-awareness training associated with personality traits and sex: a pilot study

107 volunteers learning Reiki-Do self-awareness techniques participated in this study. Results indicate that personality traits in healthy participants might be affected by specific self-awareness training, such as Reiki-Do, with participants' sex playing an independent role.     

Cross-Cultural Validation of the Rorschach Developmental Index

The Developmental Index (DI) has recently been introduced as a composite Rorschach measure of psychological development and maturation, which can be used both with the Comprehensive System (Exner, 2003), and with the recently developed Rorschach Performance Assessment System (Meyer, Viglione, Mihura, Erard, & Erdberg, 2011). As the DI is new, and its validity has not yet been investigated with independent non-U.S. samples, we tested the correlation between DI and age using 3 relatively large samples, 2 of which were from outside the United States (total N = 902). Other Rorschach variables presumably associated with maturation, such as complexity and productivity, were also investigated. As expected, the DI significantly correlated with age, with small variations across the 3 samples. Importantly, the correlation between DI and age remained statistically significant also after controlling for productivity (i.e., the number of responses) and complexity.     

Implicit evidence on the dissociation of identity and emotion recognition

Cognitive Processing - Recognition of identity and of emotional facial expressions of individuals are both based on processing of the human face. While most studies show these abilities to be...     

Arithmetic,set theory,reduction and explanation

Philosophers of science since Nagel have been interested in the links between intertheoretic reduction and explanation, understanding and other forms of epistemic progress. Although intertheoretic reduction is widely agreed to occur in pure mathematics as well as empirical science, the relationship between reduction and explanation in the mathematical setting has rarely been investigated in a similarly serious way. This paper examines an important and well-known case: the reduction of arithmetic to set theory. I claim that the reduction is unexplanatory. In defense of this claim, I offer some evidence from mathematical practice, and I respond to contrary suggestions due to Steinhart, Maddy, Kitcher and Quine. I then show how, even if set-theoretic reductions are generally not explanatory, set theory can nevertheless serve as a legitimate and successful foundation for mathematics. Finally, some implications of my thesis for philosophy of mathematics and philosophy of science are discussed. In particular, I suggest that some reductions in mathematics are probably explanatory, and I propose that differing standards of theory acceptance might account for the apparent lack of unexplanatory reductions in the empirical sciences.
