The role of body-esteem in predicting disordered eating symptoms: A comparison of French aesthetic athletes and non-athletic females

ObjectivesTo explore the relative contributions of self-esteem, body-esteem components and body mass index to disordered eating in aesthetic female athletes and non-athletic females and specifically to determine if the body-esteem components are risk factors for disordered eating.MethodsOne hundred and fifty two participants, of which 61 rhythmic gymnasts, 42 synchronized swimmers and a non-athletic group of 49 female college students completed the self-esteem scale, the body-esteem scale (satisfaction with general appearance, weight satisfaction and others' evaluations of one's body and appearance), the eating attitudes test, and the body mass index was computed.ResultsResults showed a strong heteroscedasticity for EAT-26 and therefore scores were modeled separately for the three groups. For rhythmic gymnasts, the final regression model only emphasizes the role of body-esteem attribution. For the synchronized swimmers, the final regression model combines two body-esteem dimensions (body-esteem for weight and body-esteem attribution) and their interaction. For the non-athletic group, the final regression model only emphasizes body-esteem for weight. Body mass index and low self-esteem were not predictive of disordered eating and no significant relationship was found between body-esteem for appearance and eating attitudes scores. The use of exploratory graphs such as graphs of conditioning and level plots provided more detailed information on the relationship between body-esteem dimensions and eating attitude scores.ConclusionsResults contributed to the growing literature on disordered eating suggesting that attention must be paid to body-esteem for weight and attribution in the understanding of disordered eating and their interaction. Future research should take into consideration the complexity of these results and use a larger sample of aesthetic athletes to elaborate on the current findings.

Reaction times as a measure of uncertainty

In this article, a method is presented to analyse relationships between detection or discrimination frequencies and reaction times in psychophysical tasks. It is shown in three empirical data sets that reaction time decreases as a linear function of the absolute value of the logit transforms of the response probabilities. Such a function stresses the characteristic uncertainty associated with subjects' responses and the relation between their response parameters and the response criterion used by the subjects.     

Spatial memory of domestic dogs (Canis familiaris) for hidden objects in a detour task

Spatial memory of domestic dogs (Canis familiaris) for hidden objects was investigated via a visible displacement problem of object permanence with a detour paradigm. Experiment 1 showed that dogs were able to spontaneously locate a disappearing object in a detour situation. In Experiments 2 and 3, dead reckoning and allocentric spatial information were put in conflict. Results revealed that dogs simultaneously encoded both sources of information when they had to bypass an obstacle to locate a hidden object. Experiment 3 also revealed that, over the course of testing, dogs gradually learned to rely predominantly on allocentric cues when the detour involved several reorientations. The current study reveals that spatial memory of dogs for hidden objects in a detour task was guided by flexibility in processing spatial information. Dogs could simultaneously encode dead reckoning and allocentric information to locate a disappearing object and used them hierarchically according to the complexity of the detour they encountered in the environment.     

The moderating role of autonomous motivation in the job demands-strain relation: A two sample study

Although job demands are known to be detrimental to employees’ psychological health, research suggests that certain individual characteristics moderate this relationship to some extent. This two-sample study investigated whether autonomous motivation moderates the relationship between specific job demands (role overload, role ambiguity, and role conflict) and psychological distress. Hierarchical multiple regression analyses showed clear moderating effects, indicating that highly autonomously motivated employees experience less psychological distress in the presence of job demands than their less autonomously motivated counterparts. Theoretical and practical implications are discussed in light of the job demands–strain perspective and self-determination theory.     

Speech rate as a sticky switch: a multiple lesion case analysis of mutism and hyperlalia

Though it has long been known on the basis of clinical associations and serendipitous observation that speech rate is related to mood and psychomotor baseline, it is less known that speech rate is also related to libido and to immune function. We make the case for a bipolar phenomenon of "psychic tonus," encompassing all these dimensions. The elated, agitated, libidinal, immunofacilitated, and talkative pole is an "approach" disposition primarily activated by the normal left hemisphere-especially, though not exclusively, its frontal lobe. The dejected, lethargic, delibidinized, immunosuppressed, and mute pole is an "avoidance" disposition primarily activated by the normal right hemisphere-especially, though not exclusively, its frontal lobe. In support of this proposed model, we present new evidence, via meta-analysis of previously published single lesion case reports, of a highly significant association between right hemisphere lesions and non-aphasic hyperlalia, and between left hemisphere lesions and non-aphasic mutism.     

Hemispheric lateralization of the EEG during wakefulness and REM sleep in young healthy adults

EEG recordings confirm hemispheric lateralization of brain activity during cognitive tasks. The aim of the present study was to investigate spontaneous EEG lateralization under two conditions, waking and REM sleep. Bilateral monopolar EEG was recorded in eight participants using a 12-electrode montage, before the night (5 min eyes closed) and during REM sleep. Spectral analysis (0.75-19.75 Hz) revealed left prefrontal lateralization on total spectrum amplitude power and right occipital lateralization in Delta activity during waking. In contrast, during REM sleep, right frontal lateralization in Theta and Beta activities and right lateralization in occipital Delta activity was observed. These results suggest that spontaneous EEG activities generated during waking and REM sleep are supported in part by a common thalamo-cortical neural network (right occipital Delta dominance) while additional, possibly neuro-cognitive factors modulate waking left prefrontal dominance and REM sleep right frontal dominance.
