Potential nutrition messages in magazines read by college students

Advertisements in magazines read by 12% or more of college students enrolled in an introductory nutrition class were surveyed for hidden food and nutrition messages. Meanings were identified by categories of activities, products, and people. Less than 10% of the ads featuring people fell into food categories. Of these, more were for alcohol and supplements; fewer were for basic or extra-calorie foods. Hidden messages for females could imply beauty through fashion products, beauty aids, and supplements but with a nutrition slimming plan. Males may be receiving a subtle message that food choices do not matter, and that alcohol and supplements are desirable in everyday life.     

An experiment on the theory of visual motion perception

Two classes of theories of motion perception were studied: correlation and gradient models (in the sense of D. Marr). Random-dot kinematograms with a shifted square were presented to subjects, and the 80% threshold for detection of correct direction of movement was determined. Correlation models predict scale invariance, that is, a constant shift measured in units of texture elements of the translated pattern in spite of a geometric magnification. This was refuted for all subjects. The increase of the recognizable translation with the area of the translated form was verified except for the patterns with the largest texture elements (8 minutes of arc). This prediction, however, is not very specific for competing theories. Gradient models are not yet fully specified, and they contain some free parameters. They cannot be tested strictly, but there exist reasonable numerical parameter values by which our data can be satisfactorily explained.     

Perelman's rhetorical foundation of philosophy

This article is a Gadamer-Perelman's debate. The author points out the limits of the gadamerian's hermeneutic conception of philosophy and criticizes this conception from Perelman's new rhetoric point of view. Instead of speaking of truth as an ontological originary experience, the rhetorical foundation of philosophy allows us to say that in philosophy the important is the contrastation and the confrontation of criteria and that, for that reason, philosophy is above all characterized by discussibility.Philosophical argumentation, like juridical argumentation, constitutes applications, to different domains, of a theory of argumentation which we consider as a new rhetoric.By identifying this theory with the general theory of persuasive speech, which seeks to obtain the intellectual as well as the emotional adherence of an audience, no matter which, we state that all speeches which do not aspire to an impersonal validity proceed from rhetoric. (Ch. Perelman,L'empire rhétorique, p. 177).But, if one does not admit that the philosophical thesis may be founded on evident intuitions, it will be necessary to reccur to argumentative technics to make them prevail. The new rhetoric then becomes the indispensable tool of philosophy. (Ch. Perelman,L'empire rhétorique, p. 21).     

A Psychoanalytic Grave Walk—Scenic Memory of the Shoah. On the Transgenerational Transmission of Extreme Trauma in Germany

In this article we describe a phase of a long-term psychoanalysis of a daughter of Shoah Survivors. The article is part of a research project conducted at the Sigmund Freud-Institute in Frankfurt/Main. The focus of the study is on the transmission of extreme trauma from the First to the Second Generation, with special reference to Germany. "Scenic memory of the Shoah" is presented as a concept that stresses the non-verbal, unconscious communication between the generations. The so-called "concretistic" behavior of the Second Generation, which has been described in the literature, is conceptualized here as scenic memory of the traumatic experiences during Nazi persecution, that is, a highly symbolic and metaphorical expression of the extreme trauma handed down to the patient by the parents.     

Links between local language competence and peer relations among Swiss and immigrant children: the mediating role of social behavior

The primary aim of this investigation was to evaluate a model in which children's social behaviors, including prosocial behavior, setting limits, and social withdrawal, were hypothesized to mediate the links between local language competence (LLC) and peer acceptance and victimization. Longitudinal data were collected via teacher and peer reports on 541 (286 boys and 255 girls) immigrant and Swiss native 5-to-6 year-old kindergarteners. Results showed the immigrant children were less fluent in the local language compared to native Swiss classmates. Moreover, results from structural equation models, with bootstrap tests of indirect effects, indicated that social behaviors mediated the link between LLC and the quality of children's peer relationships. Implications of these findings for school professionals are discussed, such as the need to help immigrant children make a smoother transition to their host communities by providing additional language and social supports while children acculturate and acclimate to their new surroundings and peer group.     

The mental representation of the magnitude of symbolic and nonsymbolic ratios in adults

This study mainly investigated the specificity of the processing of fraction magnitudes. Adults performed a magnitude-estimation task on fractions, the ratios of collections of dots, and the ratios of surface areas. Their performance on fractions was directly compared with that on nonsymbolic ratios. At odds with the hypothesis that the symbolic notation impedes the processing of the ratio magnitudes, the estimates were less variable and more accurate for fractions than for nonsymbolic ratios. This indicates that the symbolic notation activated a more precise mental representation than did the nonsymbolic ratios. This study also showed, for both fractions and the ratios of dot collections, that the larger the components the less precise the mental representation of the magnitude of the ratio. This effect suggests that the mental representation of the magnitude of the ratio was activated from the mental representation of the magnitude of the components and the processing of their numerical relation (indirect access). Finally, because most previous studies of fractions have used a numerical comparison task, we tested whether the mental representation of magnitude activated in the fraction-estimation task could also underlie performance in the fraction-comparison task. The subjective distance between the fractions to be compared was computed from the mean and the variability of the estimates. This distance was the best predictor of the time taken to compare the fractions, suggesting that the same approximate mental representation of the magnitude was activated in both tasks.     

The Wartegg Zeichen Test: a literature overview and a meta-analysis of reliability and validity

All available studies on the Wartegg Zeichen Test (WZT; Wartegg, 1939) were collected and evaluated through a literature overview and a meta-analysis. The literature overview shows that the history of the WZT reflects the geographical and language-based processes of marginalization where relatively isolated traditions have lived and vanished in different parts of the world. The meta-analytic review indicates a high average interscorer reliability of rw = .74 and high validity effect size for studies with clear hypotheses of rw = .33. Although the results were strong, we conclude that the WZT research has not been able to establish cumulative knowledge of the method because of the isolation of research traditions.     

A psychophysiological investigation of mourning: There are two sides to the story

Intergroup friendship and children's intentions for social exclusion in integrative classrooms: the moderating role of teachers' diversity beliefs

We examine children's intentions to socially exclude other children with special educational needs in integrative classrooms. Based on developmental and diversity research, we hypothesize that intergroup friendship leads to lower intentions to socially exclude. We also examine the moderating role of teachers' diversity beliefs on the proposed relationship. We obtained social network and questionnaire measures from 439 primary school pupils from 20 school classes, and analyzed them with multilevel modeling. In support of the moderation hypothesis, results show that intergroup friendship was only associated with lower intentions for social exclusion if teachers saw value in diversity for their class. The results offer important insights into intergroup contact theory and its use for designing implications for integrative education.
