From reorienting of attention to biased competition: Evidence from hemifield effects

When a distractor was presented simultaneously with or directly following a target, it produced more interference when it was presented in the same visual hemifield as the target than when it was presented in the opposite visual field. This result is interpreted in terms of biased competition; there is more competition between stimuli when they are presented in the same visual field, rather than in opposite visual fields. However, when the distractor was presented 125 msec or more prior to the target, this pattern was reversed. In those cases, there was more distractor interference when target and distractor were presented in opposite visual fields. This can be explained by assuming that attention was captured by the distractor, and that there was an additional cost of reorienting to a location in the opposite visual field.     

Auditory temporal cues can modulate visual representational momentum

In representational momentum (RM), the final position of a moving target is mislocalized in the direction of motion. Here, the effect of a concurrent sound on visual RM was demonstrated. A visual stimulus moved horizontally and disappeared at unpredictable positions. A complex tone without any motion cues was presented continuously from the beginning of the visual motion. As compared with a silent condition, the RM magnitude increased when the sound lasted longer than and decreased when it did not last as long as the visual motion. However, the RM was unchanged when a brief complex tone was presented before or after the target disappeared (Experiment 2) or when the onset of the long-lasting sound was not synchronized with that of the visual motion (Experiments 3 and 4). These findings suggest that visual motion representation can be modulated by a sound if the visual motion information is firmly associated with the auditory information.     

On Generalization of Definitional Equivalence to Non-Disjoint Languages

For simplicity, most of the literature introduces the concept of definitional equivalence only for disjoint languages. In a recent paper, Barrett and Halvorson introduce a straightforward generalization to non-disjoint languages and they show that their generalization is not equivalent to intertranslatability in general. In this paper, we show that their generalization is not transitive and hence it is not an equivalence relation. Then we introduce another formalization of definitional equivalence due to Andréka and Németi which is equivalent to the Barrett–Halvorson generalization in the case of disjoint languages. We show that the Andréka–Németi generalization is the smallest equivalence relation containing the Barrett–Halvorson generalization and it is equivalent to intertranslatability, which is another definition for definitional equivalence, even for non-disjoint languages. Finally, we investigate which definitions for definitional equivalences remain equivalent when we generalize them for theories in non-disjoint languages.

     

‘Ought’ implies ‘can’ against epistemic deontologism: beyond doxastic involuntarism

Synthese - According to epistemic deontologism, attributions of epistemic justification are deontic claims about what we ought to believe. One of the most prominent objections to this conception,...     

Sex differences in the development of physical aggression: An intergenerational perspective and implications for preventive interventions

This article reviews the state of knowledge on the development of chronic physical aggression (CPA), with the aim of identifying the most effective prevention strategies. We specifically focus on the early development of physical aggression, on sex differences in the use of physical aggression, and on the transmission of behavior problems from one generation to the other. The body of research on the development of CPA from the past three decades that we review shows increasing evidence that its prevention requires a long-term biopsychosocial developmental approach which also must include an intergenerational perspective. Recent genetic and epigenetic research has indicated that there are both important genetic and environmental effects on gene expression which start at conception. We conclude that one of the most effective strategies to break the intergenerational transmission of CPA involves giving long-term support to pregnant women with a history of behavior problems, their spouse, and their offspring.     

Axiomatizing Relativistic Dynamics without Conservation Postulates

A part of relativistic dynamics is axiomatized by simple and purely geometrical axioms formulated within first-order logic. A geometrical proof of the formula connecting relativistic and rest masses of bodies is presented, leading up to a geometric explanation of Einstein’s famous E = mc ². The connection of our geometrical axioms and the usual axioms on the conservation of mass, momentum and four-momentum is also investigated.     

‘Why not Lukács?’ or: on Non-Bourgeois Bourgeois Being

The Lukács Circle in Szeged, a spontaneous, unofficial organization of young Hungarian scholars and philosophy teachers, characteristically represented Georg Lukács' influence on young Hungarian intelligentsia in the period of late socialism. In this paper, the author recalls and critically analyses the intellectual milieu and motives that led a considerable part of young Hungarian intelligentsia of that time to make a cult of Lukács' philosophy. The key to the analysis is the ambiguous character of the political feelings and philosophical orientation of many young people in the period of late socialism and the paradoxical non-bourgeois bourgeois character of Lukács' philosophy. Lukács' young followers were dissatisfied with the political conditions of real socialism and with official Marxism. However, they considered themselves Marxists and were convinced by the anti-capitalist, romantic idea of democratic socialism. In the eyes of his young followers, Lukács was a genuine philosopher whose teaching was interwoven by his wide-ranging bourgeois middle-class education, promising both a real philosophical alternative to official Marxism and a high-level philosophical foundation for a non-capitalist but democratic future human history. The author argues that Lukács' philosophy did not satisfy these expectations. In his political philosophy, the philosopher could not move away from the mythological idea concerning the leading role of the communist party and therefore could not elaborate a genuine philosophical foundation for the idea of democratic socialism. Despite the superiority of his philosophy, his methodology and approach to the history of philosophy failed to provide a real philosophical alternative to the Bolshevik tradition of Marxism.     

A warm heart and a clear head. The contingent effects of weather on mood and cognition

Prior studies on the association between weather and psychological changes have produced mixed results. In part, this inconsistency may be because weather's psychological effects are moderated by two important factors: the season and time spent outside. In two correlational studies and an experiment manipulating participants' time outdoors (total N = 605), pleasant weather (higher temperature or barometric pressure) was related to higher mood, better memory, and "broadened" cognitive style during the spring as time spent outside increased. The same relationships between mood and weather were not observed during other times of year, and indeed hotter weather was associated with lower mood in the summer. These results are consistent with findings on seasonal affective disorder, and suggest that pleasant weather improves mood and broadens cognition in the spring because people have been deprived of such weather during the winter.     

Who gets mad,sad, scared or happy at discipline? Emotion attributions explain child externalizing behaviour

Few studies have linked parental discipline with children's emotional experiences, and not much data explore children's emotional attributions to discipline linked to externalizing behaviour. With a sample from Brazil, this study examines which emotions children most aptly attribute to a protagonist facing spanking, time-out or inductive discipline for norm violations. We hypothesized that anger, sadness, and fear would have higher attribution rates at spanking or time-out, relative to inductive discipline and that happiness would have higher attribution rates at induction relative to the other discipline modalities. We expected these findings to be more pronounced in older children. Based on emotional functions, we also tested the role of neutrality and happiness attributions to discipline in children's externalizing behaviour. A two-way MANOVA, with discipline and child age as explanatory variables, showed that children attributed more anger at time-out or spanking than at induction, and more happiness and neutrality at induction than at either time-out or spanking. Older children attributed significantly more sadness and less fear or neutrality. Hierarchical regressions showed that child externalizing behaviour was negatively related to happy attributions in discipline independently of child emotion situation knowledge or demographics. The results are interpreted in light of a functional view of emotions.     

Why do we share aggressive online content? Testing a short cycle model

The present study aimed to observe the impacts of aggressive online content exposure and personality on aggressive content sharing, considering the mediating role of positive and negative affects. A total of 302 Brazilians, equally divided into two groups, participated in a social network simulation, being exposed to aggressive (experimental group) or neutral (control group) posts and choosing what they would like to share on this site (among aggressive or nonaggressive material). A factorial MANOVA showed a significant difference for positive and negative affects and aggressive content sharing (Wilks' Λ = 0.936; F[3, 298] = 6.812; p = .001; η² = 0.064). Through structural equation modeling, an explanatory model was also tested, in which this behavior was directly predicted by aggressive online content exposure and suffered indirect effects from openness, conscientiousness, and extroversion, mediated by positive affects (goodness-of-fit index = 0.997, comparative fit-index = 0.998, Tucker-Lewis index = 0.996, SRMR = 0.028, root-mean-square error of approximation = 0.035, CI = 0.003−0.054). It is possible to conclude that the objectives are met, highlighting the contribution to understanding aggressive online behavior through the proximal processes described in the general aggression model.
