Clarifying body-image disturbance: analysis of a multidimensional model using structural modeling

A multidimensional model of body-image disturbance was tested. The model incorporated the concepts of body-size distortion, preference for thinness, body dissatisfaction, and fear of fatness as predictors of restrictive eating. The LISREL 7 program was used to perform a structural modeling analysis of the theoretical model. A total of 175 women participated in the study (54 eating-disordered patients and 121 undergraduate students). The results supported the hypothesized four-dimensional model relative to alternative one-, two-, and three-dimensional models. Body dissatisfaction appeared to be directly affected by both body-size distortion and preference for thinness. Fear of fatness was found to be the best predictor of restrictive eating. The results appeared consistent across the clinical and nonclinical samples. These data may help resolve many of the current controversies in the body-image literature. The results also suggested the need to develop more sound assessment instruments for fear of fatness.

Breaking the Habit: On the Highly Habitualized Nature of Meat Consumption and Implementation Intentions as One Effective Way of Reducing It

Reducing meat consumption is an important element of an effective climate protection strategy, but meat consumption is highly habitualized and therefore difficult to change. This article uses an extended version of the theory of planned behavior with habit strength as additional predictor. In one longitudinal (N?=?227) and one prospective correlational study (N?=?212), attitudes toward and perceived ease of meat consumption reduction explained about 60% of variance of meat consumption reduction intentions, with habit strength being the strongest correlate of actual self-reported meat consumption. A third experimental study (N?=?192) demonstrated that implementation intentions can be an effective strategy for realizing reduction aims. We discuss the central role of habits for meat consumption.     

The Scandal of Deduction

This article provides the first comprehensive reconstruction and analysis of Hintikka’s attempt to obtain a measure of the information yield of deductive inferences. The reconstruction is detailed by necessity due to the originality of Hintikka’s contribution. The analysis will turn out to be destructive. It dismisses Hintikka’s distinction between surface information and depth information as being of any utility towards obtaining a measure of the information yield of deductive inferences. Hintikka is right to identify the failure of canonical information theory to give an account of the information yield of deductions as a scandal, however this article demonstrates that his attempt to provide such an account fails. It fails primarily because it applies to only a restricted set of deductions in the polyadic predicate calculus, and fails to apply at all to the deductions in the monadic predicate calculus and the propositional calculus. Some corollaries of these facts are a number of undesirable and counterintuitive results concerning the proposed relation of linguistic meaning (and hence synonymy) with surface information. Some of these results will be seen to contradict Hintikka’s stated aims, whilst others are seen to be false. The consequence is that the problem of obtaining a measure of the information yield of deductive inferences remains an open one. The failure of Hintikka’s proposal will suggest that a purely syntactic approach to the problem be abandoned in favour of an intrinsically semantic one.     

Development of the self-concept during adolescence

Adolescence is a period of life in which the sense of 'self' changes profoundly. Here, we review recent behavioural and neuroimaging studies on adolescent development of the self-concept. These studies have shown that adolescence is an important developmental period for the self and its supporting neural structures. Recent neuroimaging research has demonstrated that activity in brain regions associated with self-processing, including the medial prefrontal cortex, changes between early adolescence and adulthood. These studies indicate that neurocognitive development might contribute to behavioural phenomena characteristic of adolescence, such as heightened self-consciousness and susceptibility to peer influence. We attempt to integrate this recent neurocognitive research on adolescence with findings from developmental and social psychology.     

Fine motor skills enhance lexical processing of embodied vocabulary: A test of the nimble-hands,nimble-minds hypothesis

Research suggests that fine motor skills (FMS) are linked to aspects of cognitive development in children. Additionally, lexical processing advantages exist for words implying a high body–object interaction (BOI), with initial findings indicating that such words in turn link to children’s FMS—for which we propose and evaluate four competing hypotheses. First, a maturational account argues that any links between FMS and lexical processing should not exist once developmental variables are controlled for. Second, functionalism posits that any link between FMS and lexical processing arises due to environmental interactions. Third, the semantic richness hypothesis argues that sensorimotor input improves lexical processing, but predicts no links between FMS and lexical processing. A fourth account, the nimble-hands, nimble minds (NHNM) hypothesis, proposes that having greater FMS improves lexical processing for high-BOI words. In two experiments, the response latencies of preschool children (n?=?90, n?=?76, ages?=?5;1) to 45 lexical items encompassing high-BOI, low-BOI, and less imageable words were measured, alongside measures of FMS, reasoning, and general receptive/expressive vocabulary. High-BOI words appeared to show unique links to FMS, which remained after accounting for low-BOI and less imageable words, general vocabulary, reasoning, and chronological age. Although further work is needed, the findings provide initial support for the NHNM hypothesis.
