Personality traits and endocrine response as possible asymmetry factors of agonistic outcome in karate athletes

Individual variations of plasma levels of hormones testosterone (T) and cortisol (C), before (pre) and after (post) Kumite (real fight) and Kata (ritualized fight) were measured in male karate athletes and analyzed in relation with the agonistic outcome (i.e. winning or losing the fight) and personality trait measures. T and C increased only during Kumite contest and pre‐ and post‐competition C levels were higher in losers than winners. Losers showed higher levels of harm avoidance and anxiety as well as lower level of novelty seeking than winners. Importantly, novelty seeking negatively correlates with pre C and the higher the level of risk assessment, emotionality and insecurity indexes the higher the pre C level. In conclusion, personality traits might be an important factor asymmetry between athletes influencing both the probability of winning or losing an agonistic interaction and the different anticipatory endocrine response to the incipient fight.

Socio‐economic,socio‐political and socio‐emotional variables explaining school bullying: a country‐wide multilevel analysis

Why do some countries, regions and schools have more bullying than others? What socio‐economic, socio‐political and other larger contextual factors predict school bullying? These open questions inspired this study with 53.316 5th‐ and 9th‐grade students (5% of the national student population in these grades), from 1,000 schools in Colombia. Students completed a national test of citizenship competencies, which included questions about bullying and about families, neighborhoods and their own socio‐emotional competencies. We combined these data with community violence and socio‐economic conditions of all Colombian municipalities, which allowed us to conduct multilevel analyses to identify municipality‐ and school‐level variables predicting school bullying. Most variance was found at the school level. Higher levels of school bullying were related to more males in the schools, lower levels of empathy, more authoritarian and violent families, higher levels of community violence, better socio‐economic conditions, hostile attributional biases and more beliefs supporting aggression. These results might reflect student, classroom and school contributions because student‐level variables were aggregated at the school level. Although in small portions, violence from the decades‐old‐armed conflict among guerrillas, paramilitaries and governmental forces predicted school bullying at the municipal level for 5th graders. For 9th graders, inequality in land ownership predicted school bullying. Neither poverty, nor population density or homicide rates contributed to explaining bullying. These results may help us advance toward understanding how the larger context relates to school bullying, and what socio‐emotional competencies may help us prevent the negative effects of a violent and unequal environment.

A corpus-based analysis of verb continuation frequencies for syntactic processing

In the experimental study of how much verb guidance occurs in parsing syntactic ambiguity, the preference of an ambiguously subcategorized verb for its continuations is a relevant factor in the choice of the stimuli and in the interpretation of the results. Many methods have been used to measure this bias, ranging from experimenter's intuitions to sentence completion studies. In this paper, I assume that an acceptable definition of frequency is the count of the occurrences in a corpus, and I provide some cooccurrence counts calculated on a set of verbs and their syntactic siblings in a subset of the Penn Treebank (Marcus, Santorini, & Marcinkiewicz, 1993). Second, I perform some correlations with sentence completion and sentence production studies, which show that the two data collection methods are not strongly correlated with the corpus counts. Finally, I analyze the stimuli of some experiments which have shown evidence both in favor of the garden path theory of sentence processing and the lexical guidance theory. I argue that all the stimuli were balanced, and that a minimal attachment effect is not a consequence of the overall NP-bias of the stimuli. Moreover, evidence from the relation between processing times and verb completions with declarative and interrogative complementizers is used to argue that the parser is sensitive to the lexical content of the complementizers.     

Husserl's Theory of Language as Calculus Ratiocinator

This paper defends an interpretation of Husserl's theory of language, specifically as it appears in the Logical Investigations, as an example of a larger body of theories dubbed 'language as calculus'. Although this particular interpretation has been previously defended by other authors, such as Hintikka and Kusch, this paper proposes to contribute to the discussion by arguing that what makes this interpretation plausible are Husserl's distinction between the notions of meaning-intention and meaning-fulfillment, his view that meaning is instantiated through meaning-intending acts of transcendental consciousness, and his view that the content of meaning-intending acts is ideal meaning simpliciter. As well, the paper argues that the phenomenological method of reduction itself presupposes the notion that reality as such can be reached by subtracting the influence of the language of the natural attitude and its ontological commitments and it, thus, presupposes the conception of language as a reinterpretable calculus.     

Restrained drinking and cognitive control among adolescents

The present study investigated restrained drinking and self-control in relation to alcohol consumption and problem drinking in a sample of adolescents. One hundred ninety-eight high school students (97 males and 101 females; mean age = 16.45 years) completed questionnaires that assessed levels of alcohol consumption, problem drinking, restrained drinking, and cognitive self-control. The findings were similar for males and females: higher levels of restrained drinking, as measured by cognitive emotional preoccupation (CEP), predicted higher levels of alcohol consumption and problem drinking. Moreover, it was high CEP in combination with a low score on a general measure of cognitive self-control that differentiated problem drinking from high levels of drinking. The results are consistent with previous research on young adults. The findings are discussed in relation to Baumeister and Heatherton's (1996) model of self-regulation failure.

Dietary restraint and negative affect as mediators of body dissatisfaction and bulimic behavior in adolescent girls and boys.

Stice's dual pathway model of dietary restraint and negative affect was examined in both adolescent girls and boys. Self-report measures assessing body dissatisfaction, dietary restraint, negative affect and bulimic behavior were administered to 267 girls and 199 boys aged between 12 and 16 years. The findings for the girls were consistent with Stice's model, in that they indicated that both dietary restraint and negative affect mediated the relationship between body dissatisfaction and bulimic behavior. For the boys who desired a thinner body size, only negative affect was found to mediate the relationship between body dissatisfaction and bulimic behavior. On the other hand, for boys who desired a larger body size, both body dissatisfaction and dietary restraint were found to exert an independent effect on bulimic behavior. As boys can aspire to two contrasting and seemingly opposite body size ideals, the findings highlight that the relationship between body dissatisfaction, dietary restraint, negative affect and bulimic behavior are more complex in males than in females. Further research using longitudinal designs is needed in order to test the directional and bidirectional nature of the observed interrelationships.     

Inhomogeneous surrounds, conflicting frameworks, and the double-anchoring theory of lightness

The empirical question of whether or not the lightness of a region is accounted for purely by the average luminance of its surround has a complex answer that depends on whether such a region is an increment, a decrement, or intermediate relative to the luminances of the contiguous surfaces. It is shown here that a new model of lightness, based on anchoring principles, predicts and clarifies such intricacies. In this model, the luminance of the target region determines its lightness in two ways: indirectly, by causing it to group with parts of its surround and thus defining the nested frameworks to which it belongs; and directly, by anchoring it to the highest luminance and to the average surround luminance in each of these frameworks. Inter- and intraindividual differences in lightness assessment are shown to emerge under grouping conditions that create unstable, conflicting frameworks.     

Simultaneous lightness contrast on plain and articulated surrounds

Simultaneous lightness contrast is stronger when the dark and light backgrounds of the classic display (where one of the targets is an increment and the other is a decrement) are replaced by articulated fields of equivalent average luminances. Although routinely attributed to articulation per se, this effect may simply result from the increase in highest luminance in the light articulated, vs plain, background; by locally darkening the decremental target, such an increase would amplify the difference between the targets. We disentangled the effects of highest luminance and articulation by measuring, separately, the magnitude of lightness contrast on dark and light plain and articulated backgrounds. We found that highest luminance and articulation contribute separately to the final illusion.
