Body size and body esteem in women: The mediating role of possible self expectancy

We predicted that an expectancy of acquiring a feared fat self and an expectancy of acquiring a hoped-for thin self both mediate the impact of body size on women's body esteem. We also predicted that the mediating pathway through the feared fat self would be stronger than that through the hoped-for thin self. A community sample of 251 women reported their age, height, weight, and completed measures of body esteem and expectancy perceptions of acquiring the feared fat and hoped-for thin selves. Bayesian Structural Equation Modeling (SEM) demonstrated that expectancies about the feared fat self and about the hoped-for thin self mediated the relationship between body size and body esteem. Bayesian SEM also revealed that the pathway through the feared fat self was stronger than that through the hoped-for thin self. Implications for future research and the development of eating pathology are discussed.     

Information underpinning anticipation of goal-directed throwing

We identified the information used to anticipate throw direction in handball. In two experiments, we examined how anticipation performance is affected when the information from one of five body areas (right arm, shoulders, hips, trunk, or total throw side) was either neutralized or decoupled from the motion of other body segments. In the first experiment, performance was significantly reduced when information from the throwing arm was neutralized, irrespective of skill levels. Skilled participants were negatively affected when the shoulders, hips, and trunk were neutralized, whereas less-skilled participants showed trends toward improvement under identical conditions. In the second experiment, partially disrupting relative motion via decoupling was not enough to reduce the anticipation performance among skilled participants to chance levels, whereas less-skilled participants lost their ability to anticipate in three conditions. Our findings suggest that skilled and less-skilled participants employ different information extraction strategies, yet information from the throwing arm is critical to anticipation for both groups. The two experiments suggest that relative motion mediated by both the absolute displacement trajectories of individual marker locations and their relative timings are important in informing anticipation, irrespective of skill level.     

No time-stretching illusion when a tone is followed by a noise

A sine tone is perceived as longer when it is preceded by a more intense noise than when presented in isolation. This is the time-stretching illusion. We conducted an experiment where the method of constant stimuli was used to examine whether a tone would also be stretched when it was followed by a noise. The duration of a tone was overestimated when it was preceded by a noise, but not when followed by a noise or when located between two consecutive noises. Moreover, the increasing of the noise intensity (from ?6 to +6 dB) relative to the tone intensity resulted in larger overestimations, but only in the condition where a tone was preceded by a noise. In brief, the duration of a tone is stretched when this tone is preceded by a noise and if this tone is not followed by a noise.     

Genetic differences in response to novelty and spatial memory using a two-trial recognition task in mice

A two-trial memory task, based on a free-choice exploration paradigm in a Y-maze, was previously developed to study recognition processes in Sprague-Dawley rats. Because this paradigm avoids the use of electric shock or deprivation that may have nonspecific effects and does not require learning of a rule, it may be particularly useful for studying memory in mice. Four inbred strains (Balb/cByJ, DBA/2J, C57BL/6J, and SJL/J), an F1 hybrid (C57BL/6 x SJL/J), and one outbred strain (CD1) were used to validate this task in mice and to characterize a strain distribution in response to novelty and working memory. Exploration was measured with a short (2 min) intertrial interval (ITI) between acquisition and retrieval, while memory was examined with longer intervals (30 min, 1 h, and 2 h). A study of the time course of the response to novelty revealed varying degrees of preference and/or habituation to novelty among the different strains, with CD1 exhibiting a very high response to novelty and others showing lower (C57 x SJL hybrids) to complete absence (SJL) of exploration of novelty. Memory span, assessed with increasing ITIs, varied widely among strains from 30 min (C57 x SJL hybrids) to at least 2 h (C57 and BALB). Such demonstrated sensitivity to a wide range of behavioral phenotypes supports the use of this spatial memory task as an effective tool for the study of genetic influences on the response to novelty and recognition processes in mice.     

Perfectionism Cognitions, Rumination, and Psychological Distress

The current study examined the extent to which dimensions of perfectionism are associated with a ruminative response orientation and the experience of cognitive intrusions in response to stressful events. Our main goal was to test the hypothesis that individuals characterized by frequent automatic thoughts involving perfectionistic themes would also be characterized by a ruminative response orientation when distressed and they would report intrusive thoughts and images following the experience of a stressful event. A sample of 65 students completed several measures, including the Perfectionism Cognitions Inventory, the Multidimensional Perfectionism Scale, the Response Styles Questionnaire, the Impact of Events Scale, and indices of depression and anxiety. Correlational analyses confirmed that high scores on the Perfectionism Cognitions Inventory were correlated with a ruminative response orientation and the reported experience of intrusive thoughts and images following the experience of a stressful event. High levels of perfectionism cognitions, socially prescribed perfectionism, and rumination were also correlated with measures of depression and anxiety representingthe tripartite model. The results support the view that there is a salient cognitive aspect to perfectionism and the experience of frequent perfectionistic cognitions and related forms of rumination contribute to levels of psychological distress.     

The freedom of the deconstructed postmodern subject

Poststructuralists have tried to deconstruct the subject, that is, demonstrate that it is constituted by the system of cultural and linguistic relations in which it is found. The result is that just at the moment when self-actualization seems for the first time to be politically possible for many hitherto marginalized subjects, they, and subjects more generally, appear to have been denatured – reduced to the cultural systems which are the condition of their possibility and consequently deprived of the freedom which is clearly necessary for any form of self-actualization. This paper, while acknowledging that subjects are indeed culturally and linguistically constituted, argues on the basis of a holistic, emergent property hypothesis that structure or form can generate content that nevertheless transcends the structure or form that constitutes it. On this view the subject is irreducibly transcendent to the system of relations from within which it arises, and the deconstructed subject thus remains capable of free choice and self-actualization.     

The overcoming of overcoming: On Dominique Janicaud

This paper aims to give an overview of the central preoccupations of the work of Dominique Janicaud. In the first part, I discuss Janicaud's basic strategy with regard to Heidegger's work, with particular reference to the question of metaphysics and its overcoming. Opposing Heidegger's alternative between the completion of metaphysics in technology (Gestell), on the one hand, and the experience of meditative thinking (Gelassenheit), on the other, Janicaud's position can be described as what I call an overcoming of all claims at overcoming, whether it concerns metaphysics, rationality or humanity. This leads, in the second part of the paper, to a discussion of Janicaud's radical and compelling reconsideration of the genealogy of rationality in his major work, La puissance du rationnel. This genealogy permits Janicaud to sketch a novel conception of reason as what he calls partage, conceived as both the shared space of dialogue and the sense of the thrown contingency of our existence. In the third part of the paper, and with reference to posthumously published work, I go on to show how this conception of partage shapes Janicaud's conception of the human condition and how this conception shows a significant debt to Pascal.     

Innocence Without Naivete,Uprightness Without Stupidity: The Pedagogical Kavannah of Emmanuel Levinas

While it is impossible to transfigurephilosophical and Judaic thought of EmmanuelLevinas into a moral agenda for education orthe programmatic regularities of a pedagogicalmethodology, this paper argues for theimportance of his work for re-openingeducational questions. These questions engagethe problem of what it could mean to livehistorically, to live within an uprightattentiveness to traces of those who haveinhabited times and places other than one'sown. In this sense, I address the problem ofremembrance as a question of and for history,as a force of inhabitation, as an inheritance weare obligated to live within, that intertwineswith our sense of limits and possibilities,hopes and fears, identities and distinctions.Substantively, this problem is manifest in howone attends to the experiences of others: howone reads, how one views, and how one listens,always historically specific normalizedpractices that in any given epoch are ingrainedin what it means to live in consort withothers, to live as though the lives of otherpeople mattered. The paper seeks to display thefecundity of the thought of Levinas forre-thinking such issues.
