Associations Between Peer Pressure and Adolescents’ Binge Behaviors: The Role of Basic Needs and Coping

Framed from a framework based on the integration of self-determination theory (Ryan &; Deci, 2000 Ryan, R. M., &; Deci, E. L. (2000). Self-determination theory and the facilitation of intrinsic motivation, social development, and well-being. American Psychologist, 55(1), 68–78. doi:10.1037/0003-066X.55.1.68[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]) and Endler and Parker’s (1990) conception of coping strategies, the authors analyzed the relationships between peer pressure and binge behaviors (binge eating and binge drinking) in adolescence. Moreover, the authors explored the mediating role of satisfaction/frustration of basic psychological needs and coping strategies in these associations. Participants were 570 high school students (M?=?15.75 years, SD?=?1.14 years) living in Italy. The study design was cross-sectional and adolescents were administered self-report questionnaires. Path analysis showed significant and positive direct associations of peer pressure with both binge eating and binge drinking. Moreover, findings show that there is an indirect path in which peer pressure is positively associated with need frustration that is related to the use of emotion-oriented coping strategies that, on their turn, are associated with binge eating. Differently, binge drinking seems to be only directly related to peer pressure. The authors put light to the complex nature of the relationships between peer pressure and binge behaviors in adolescence, taking into account the separate contribution of need satisfaction and need frustration, as well as of coping strategies. Finally, practical implications of the study are discussed.     

Personality correlates of HIV stigmatization in Russia and the United States

To determine whether stigmatizing attitudes towards HIV/AIDS are associated with personality traits, and whether these associations are generalizable across two cultures, we administered the English and the brief Russian version of the Revised NEO Personality Inventory, a standardized measure of a comprehensive model of personality traits, together with items assessing HIV stigmatization. We hypothesized that stigmatization would be associated chiefly with low Openness to Experience. Self-reports and observer ratings of personality and self-reports of HIV attitudes were collected from volunteers recruited by research assistants. HIV stigmatization was more pronounced in Russia than in the United States, but it was similarly related to personality traits, chiefly low Openness to Experience, a variable associated with other forms of prejudice, and low Agreeableness, suggesting a lack of altruism and sympathy. HIV stigmatization is especially likely to be a problem with people, and in cultures, low in Openness to Experience.     

Finding Treasures: Is the Community of Philosophical Inquiry a Methodology?

Studies in Philosophy and Education - In the world of Philosophy for Children (P4C), the word “method” is found frequently in its literature and in its practitioner’s handbooks....     

A PERSPECTIVAL DEFINITION OF KNOWLEDGE

In this paper an improved formulation of the classical tripartite view of knowledge is proposed and defended. This formulation solves Gettier's problem by making explicit what is concealed by the symbolic version of the tripartite definition, namely, the perspectival context in which concrete knowledge claims are evaluated.     

Television and aggression: a test of a mediated model with a sample of Portuguese students

We examined the role of identification with violent TV heroes, enjoyment of TV violence, and perceived reality in TV violence as mediators of the relationship between viewing TV violence and subsequent physical and verbal aggression. A sample of 722 4th, 6th, and 8th grade students from schools in the central region of Portugal completed measures assessing enjoyment of TV violence, perceived reality, aggression, identification with violent TV heroes, and exposure to TV violence. The results showed that the relationship between TV violence and physical aggression is mediated by enjoyment of TV violence, perceived reality in TV violence, and identification with violent TV heroes. The TV violence to verbal aggression relationship was also mediated by enjoyment of TV violence.     

Relative age effect in Olympic Taekwondo athletes

Relative age effects refer to the effects of age differences among individuals who have been grouped together for a performance activity. This study aimed to investigate the relative age effect on Olympic Taekwondo athletes, in several Olympic Games, and in both sexes. The study sample consisted of 291 athletes who had competed in Atlanta, Sydney, and Beijing Olympic Games. The relative age effect was examined for the general distribution of athletes by quartile, for each of the individuals, and for male and female athletes. There were no discernable effects of relative age on Olympic Taekwondo athletes.     

Neurofunctional (re)organization underlying narrative discourse processing in aging: evidence from fNIRS

Relatively few studies have analyzed the mechanisms underlying the cognitive changes that affect language in the elderly, and fewer have done so for narrative discourse. The goal of this study was to explore the neurofunctional changes associated with aging for different components of narrative discourse. Functional near-infrared spectroscopy (fNIRS) and behavioral data on 10 younger adults and 10 healthy elderly participants were collected. Ten younger adults in a non-proficient second language condition were included to explore the possibility that the age-related neurofunctional reorganization partly expresses demanding resource allocation. Results show within- and across-hemispheric differences in the neurofunctional pattern of activation in the older participants with reference to the younger ones, partially shared with the low-proficiency young adults, providing support for the recognized mechanisms underlying neural reserve and compensation. fNIRS was shown to be appropriate for studying the age-related neurofunctional reorganization of complex cognitive abilities.     

Towards a mathematical model of within-session operant responding

Operant response rate changes within the course of a typical free-operant experimental session. These changes are orderly, and reliably demonstrated with subjects from different species, responding under different experimental conditions. Killeen (1995) postulated that the response rate changes are a function of the interplay between arousal and satiation and offered a mathematical model for this hypothesis. Here we analyze Killeen's model, demonstrating that, although solid in its principles, it presents some flaws in its implementation. Then, based on the same principles, we build and test a new model of within-session motivation dynamics. We also demonstrate that, by representing arousal as a variable that ranges between 0 and 1, we can obtain a surprisingly simple model of free-operant response rate.     

Opioid mechanisms are involved in the disruption of arcaine-induced amnesia by context pre-exposure

Previous exposure to the training context disrupts glutamatergic N-methyl-d-aspartate receptor (NMDAr) antagonist-induced amnesia, indicating that novelty is necessary for such an amnestic effect. While there are reports that novelty-related release of opioids cause amnesia, no study has addressed whether the amnestic effect of NMDAr antagonists involve opioid mechanisms. In this study we investigated whether pharmacological manipulation of the opioid system immediately after context pre-exposure alters the amnestic effect of arcaine, a NMDAr antagonist. Adult male Wistar rats were habituated (pre-exposed) to a fear conditioning training apparatus or to a different context (open field). Immediately after pre-exposure, animals were injected with saline or naloxone (0.5 mg/kg, i.p.) or anti-beta-endorphin antibody (1:500, i.c.v.). Forty eight hours after pre-exposure session, all animals were subjected to fear conditioning acquisition protocol and saline or arcaine (30 mg/kg, i.p.) was administered immediately after training. Testing was carried out 24 h later, and freezing responses due to re-exposure to the training apparatus were recorded. Pre-exposure to the training apparatus prevented the impairment of memory induced by post-training arcaine. Administration of naloxone or anti-beta-endorphin antibody, immediately after pre-exposure to the training apparatus, reinstated the amnesic effect of post-training arcaine. The results suggest that endogenous opioid mechanisms are involved in the pre-exposure-induced loss of the amnestic effect of arcaine.     

Husserl on Geometry and Spatial Representation

Husserl left many unpublished drafts explaining (or trying to) his views on spatial representation and geometry, such as, particularly, those collected in the second part of Studien zur Arithmetik und Geometrie (Hua XXI), but no completely articulate work on the subject. In this paper, I put forward an interpretation of what those views might have been. Husserl, I claim, distinguished among different conceptions of space, the space of perception (constituted from sensorial data by intentionally motivated psychic functions), that of physical geometry (or idealized perceptual space), the space of the mathematical science of physical nature (in which science, not only raw perception has a word) and the abstract spaces of mathematics (free creations of the mathematical mind), each of them with its peculiar geometrical structure. Perceptual space is proto-Euclidean and the space of physical geometry Euclidean, but mathematical physics, Husserl allowed, may find it convenient to represent physical space with a non-Euclidean structure. Mathematical spaces, on their turn, can be endowed, he thinks, with any geometry mathematicians may find interesting. Many other related questions are addressed here, in particular those concerning the a priori or a posteriori character of the many geometric features of perceptual space (bearing in mind that there are at least two different notions of a priori in Husserl, which we may call the conceptual and the transcendental a priori). I conclude with an overview of Weyl’s ideas on the matter, since his philosophical conceptions are often traceable back to his former master, Husserl.
