Verbal memory compensation: application to left and right temporal lobe epileptic patients

This study investigates the compensatory impact of cognitive aids on left and right temporal lobe epileptic patients suffering from verbal memory disorders, who were candidates for surgery. Cognitive aids are defined in the levels-of-processing framework and deal with the depth of encoding, the elaboration of information, and the use of retrieval cues. Results indicate differential compensatory impact for left and right epileptic patients and are discussed according to the HERA model and the compensation framework.     

Personal need for structure and creative performance: the moderating influence of fear of invalidity

Previous research has suggested that personal need for structure (PNS) is negatively related to creative performance. In this article, it is argued that this relation, in fact, depends on another personality variable: personal fear of invalidity (PFI). When PFI is high, PNS should indeed be negatively associated with creativity. However, PNS should be positively associated with creativity when PFI is low, because this combination enables people to take a structured approach to creative tasks and this can be helpful to overcome their reliance on conventional and accessible task strategies. In four studies, this hypothesis is tested using different measures of creative performance. The expected interaction effect is found for measures of ideational fluency and measures of originality but not for measures of flexibility. Moreover, it is shown that the interaction effect between PNS and PFI is mediated by perseverance within thought categories.     

Suchttherapie bei abhängigen Ärzten

Background

International studies indicate an increased incidence of substance abuse disorders among physicians. This article investigates specific variables in the work field and describes existing treatment programs.

Patients and methods

In a cross-sectional study 107 physicians with and 468 without substance abuse disorders were compared. Two highly developed treatment programs in Germany and Canada are described.

Results

The high work-load associated with the medical work environment leads to reduced performance and social isolation. Treatment programs for addicted physicians work with the concept of ?help before restriction“. The abstinence rate of the 5-year Canadian program is over 90%.

Conclusions

As a form of prevention, medical students should be systematically informed about work-related stress in the medical profession. Structured treatment programs should be implemented nationwide. The expert team ?Risk of addiction in physicians“ of the German Addiction Foundation, whose members are authors of this article, may be a small step in this direction.     

Foster Parents’ Involvement in Authoritative Parenting and Interest in Future Parenting Training

We surveyed 191 Southwest Ohio foster parents regarding their involvement in authoritative parenting and interest for additional parenting education. Our results showed that most respondents reported using an authoritative parenting style and were interested in receiving future training. Involvement in authoritative parenting differed significantly based on level of education and number of years as a foster parent. Foster parents with a college degree or higher were significantly more involved in authoritative parenting than foster parents with a high school diploma or less. Those who had been a foster parent for greater than five years were significantly more likely than those who been a foster parent for five years or less to use authoritative parenting and desire future training in authoritative parenting.     

ERPs associated with visual duration discriminations in prefrontal and parietal cortex

An event-related potentials (ERP) study was undertaken to examine the role of prefrontal and parietal association cortices on selective attention and short-term memory functions in a duration discrimination task. Subjects performed better when discriminating the first stimulus relative to the second and not the reverse. Two contingent negative variations (CNV) were obtained for each stimulus duration at prefrontal regions, as well as two P300s at parietal regions. The CNV(S1) component recorded during the first stimulus (S1) appeared to be involved in selective attention at bilateral sites, while the P300(S1) component in the left hemisphere may be implicated in retaining it. The CNV(S2) wave, displayed during the second stimulus (S2), at bilateral sites and the right-sided P300(S2) wave seem to be implicated in working memory. The results indicate that recorded activity at prefrontal and parietal association cortices is tightly linked to task parameters and behavioral performances.     

Asymmetrical interactions between thirst and hunger in pavlovian-instrumental transfer

Pavlovian-instrumental transfer experiments have demonstrated that a stimulus paired with a sucrose solution under hunger will increase instrumental performance under thirst relative to a stimulus previously paired with food pellets. In Experiment 1 it was demonstrated that this difference is, in part, produced by suppression induced by the pellet stimulus, which, it was found, acted to reduce instrumental performance under thirst. In Experiment 2, the reverse shift was examined, comparing the effects of stimuli paired with either a saline solution or a sucrose solution under thirst on instrumental performance under hunger. Although the sucrose stimulus was found to elevate performance when hungry, the saline stimulus was found to be without effect. This asymmetry in the interaction between hunger and thirst is discussed in terms of the way motivational states control the interaction between sensory and affective components of the reinforcer.     

Neural effects of short-term training on working memory

Working memory training has been the focus of intense research interest. Despite accumulating behavioral work, knowledge about the neural mechanisms underlying training effects is scarce. Here, we show that 7 days of training on an n-back task led to substantial performance improvements in the trained task; furthermore, the experimental group showed cross-modal transfer, as compared with an active control group. In addition, there were two neural effects that emerged as a function of training: first, increased perfusion during task performance in selected regions, reflecting a neural response to cope with high task demand; second, increased blood flow at rest in regions where training effects were apparent. We also found that perfusion at rest was correlated with task proficiency, probably reflecting an improved neural readiness to perform. Our findings are discussed within the context of the available neuroimaging literature on n-back training.     

The Birth of the Philosophy of Sport in France 1950–1980. Part 1: from Ulmann to Rauch through Vigarello

A cursory review of the philosophy of sport readily reveals that it is dominated by Anglo-Saxon analytical philosophical milieux, in the departments of philosophy and kinesiology, the centers of bioethics, and the faculties of health around the world. In France, however, with the exception of a few researchers working in the philosophy or sport, and within an analytical paradigm, the development of the subject has gone almost unnoticed. By contrast, the discipline of history of sport clearly moved away from philosophy in France with the establishment of a separate field of study based on the Anglo-Saxon model from the work pioneer of Pierre Arnaud developed by Thierry Terret and other sports historians. Nevertheless, in French universities, faculties of philosophy have not been open to research in the philosophy of the body. The philosophy of sport is not taught as such in French Universities even if our generation pursues ways opened by Jacques Ulmann, Bernard Jeu, Bernard Guillemain, Michel Bernard, Jean-Michel Berthelot, Gilbert Andrieu, Bertrand During, André Rauch, Marie-Hélène Brousse, Françoise Labridy, and Georges Vigarello, among others, through their reflections on the philosophy of the body. This article discusses the influence of some of these authors, and especially of Georges Gusdorf, Michel Foucault, and Georges Snyders on the nature and prospects for the philosophy of sport in France.     

Individual differences in the shape bias in preschool children with specific language impairment and typical language development: theoretical and clinical implications

We investigated whether preschool children with specific language impairment (SLI) exhibit the shape bias in word learning: the bias to generalize based on shape rather than size, color, or texture in an object naming context (‘This is a wek; find another wek’) but not in a non‐naming similarity classification context (‘See this? Which one goes with this one?’). Fifty‐four preschool children (16 with SLI, 16 children with typical language [TL] in an equated control group, and 22 additional children with TL included in individual differences analyses but not group comparisons) completed a battery of linguistic and cognitive assessments and two experiments. In Experiment 1, children made generalization choices in object naming and similarity classification contexts on separate days, from options similar to a target object in shape, color, or texture. On average, TL children exhibited the shape bias in an object naming context, but children with SLI did not. In Experiment 2, we tested whether the failure to exhibit the shape bias might be linked to ability to detect systematicities in the visual domain. Experiment 2 supported this hypothesis, in that children with SLI failed to learn simple paired visual associations that were readily learned by children with TL. Analyses of individual differences in the two studies revealed that visual paired‐associate learning predicted degree of shape bias in children with SLI and TL better than any other measure of nonverbal intelligence or standard assessments of language ability. We discuss theoretical and clinical implications.
