Troubling Hope: Performing Inventive Connections in Discomforting Times

Studies in Philosophy and Education - In what follows, we revisit the most promising conceptions of “hope” while following Haraway’s admonition to “stay with the...     

Contextual effects in a metaphor verification task

The verbal transformation effect, an auditory illusion in which physically invariant repetitive verbal input undergoes perceptual transformation, has traditionally been interpreted as a speech-specific phenomenon. Experiment 1 showed that the effect is not limited to speech, but occurs in non-speech categories such as music and other complex everyday sounds, with transformations being comparable in nature and number to those in speech. Experiment 2 provided evidence for an alternative, broader-based view of the phenomenon, involving spreading activation through a multidimensional associative network of mental representations, by demonstrating that creating or activating pre-existing links between a single complex non-verbal stimulus and other representations by priming led to an increase in transformations.     

Language Switching in the Production of Phrases

The language switching task has provided a useful insight into how bilinguals produce language. So far, however, the studies using this method have been limited to lexical access. The present study provides empirical evidence on language switching in the production of simple grammar structures. In the reported experiment, Polish–English unbalanced bilinguals switched between their L1 and L2 while describing pictures of ongoing and completed actions with simple SV progressive and perfective phrases. The results show asymmetrical switching costs for progressive phrases and symmetrical switching costs with reversed dominance for perfective phrases. These findings parallel those obtained in tasks requiring the production of single words, although the present study is the first in which the same bilingual participants display different patterns of switching costs depending on the characteristics of utterances they produce. These results can be explained using recently developed models of bilingual language control.     

Normal Modal Logics Determined by Aligned Clusters

We consider the family of logics from NExt(KTB) which are determined by linear frames with reflexive and symmetric relation of accessibility. The condition of linearity in such frames was first defined in the paper [9]. We prove that the cardinality of the logics under consideration is uncountably infinite.     

Interventions stimulating prosocial helping behavior: A systematic review

This systematic review of the literature aims to identify, analyze, and synthesize studies assessing the effectiveness of interventions stimulating prosocial behavior. It concentrates on helping behavior and covers experimental and quasi-experimental research concerning interventions carried out in different settings. This review was performed in accordance with the PRISMA guidelines. Of the initial sample of 4,653 publications found in databases, 49 articles met our inclusion criteria and were classified as eligible for data extraction and narrative synthesis. The studies included in the review assessed 63 interventions, most of them targeted at children and adolescents. We distinguished three strategies stimulating prosocial behavior: behavioral, cognitive, and emotional. This review is informative for both researchers and practitioners. It provides researchers with methodological guidelines concerning how to conduct studies on the effectiveness of prosocial interventions, and it provides practitioners with guidelines on empirically tested strategies for stimulating prosocial helping behavior.

Asymptotic Densities in Logic and Type Theory

This paper presents a systematic approach for obtaining results from the area of quantitative investigations in logic and type theory. We investigate the proportion between tautologies (inhabited types) of a given length n against the number of all formulas (types) of length n. We investigate an asymptotic behavior of this fraction. Furthermore, we characterize the relation between number of premises of implicational formula (type) and the asymptotic probability of finding such formula among the all ones. We also deal with a distribution of these asymptotic probabilities. Using the same approach we also prove that the probability that randomly chosen fourth order type (or type of the order not greater than 4), which admits decidable lambda definability problem, is zero.

Statistics of Intuitionistic versus Classical Logics

For the given logical calculus we investigate the proportion of the number of true formulas of a certain length n to the number of all formulas of such length. We are especially interested in asymptotic behavior of this fraction when n tends to infinity. If the limit exists it is represented by a real number between 0 and 1 which we may call the density of truth for the investigated logic. In this paper we apply this approach to the intuitionistic logic of one variable with implication and negation. The result is obtained by reducing the problem to the same one of Dummett's intermediate linear logic of one variable (see [2]). Actually, this paper shows the exact density of intuitionistic logic and demonstrates that it covers a substantial part (more than 93%) of classical prepositional calculus. Despite using strictly mathematical means to solve all discussed problems, this paper in fact, may have a philosophical impact on understanding how much the phenomenon of truth is sporadic or frequent in random mathematics sentences.     

The Asymmetry Objection Rides Again: On the Nature and Significance of Justificatory Disagreement

Political liberalism offers perhaps the most developed and dominant account of justice and legitimacy in the face of disagreement among citizens. A prominent objection states that the view arbitrarily treats differently disagreement about the good, such as on what makes for a good life, and disagreement about justice. In the presence of reasonable disagreement about the good, political liberals argue that the state must be neutral, but they do not suggest a similar response given reasonable disagreement about what justice requires. A leading political liberal, Jonathan Quong, has recently offered a rebuttal to this asymmetry objection. His reply rests on an innovative distinction between justificatory and foundational disagreement. Quong claims that disagreements about justice in a well ordered society are justificatory while disagreements about the good are foundational, and suggests that this fact blocks the asymmetry objection. We assess Quong's solution and argue that it fails to justify legitimate state action on matters of justice but not the good. We conclude that the asymmetry objection continues to undermine political liberalism.     

Remembering War: Fabre on Remembrance

Following wars, what requirements, if any, of remembrance do we – those who live in peacetime – have? On whom do they fall? Who must be remembered? How should they be remembered? Fabre offers us an account of remembrance that answers some of those questions and provides a helpful framework for working through the others. It is philosophically nuanced as well as attuned to the complexity of war and informed by actual commemorative practices. In this article, however, I expand Fabre's list of desiderata that a good account of war remembrance must meet. I argue that Fabre's account needs to be refined and, at least in one respect, revised in light of these new desiderata.
