L’internalisation des stéréotypes chez les « petits » fonctionnaires : impact du contact avec le public et du prestige perçu

This paper focuses on the internalization of stereotypes among French office workers in the lower category (category C). More precisely, we investigated the impact of two independent factors on this internalization of stereotypes: the perceived external prestige and public contact. Results obtained using questionnaires completed by 175 office workers have mainly showed that, in accordance with previous studies, the external prestige perceived influence significantly the internalization of stereotypes. But, contrary to previous studies, the frequency of contacts with the public has no impact on the internalization of stereotypes in our sample. Our results invite furter work on this population of office employees who is, paradoxically, increasingly confronted with stereotypes but subject of very few studies.     

Are monkeys able to plan for future exchange?

Whether or not non-human animals can plan for the future is a hotly debated issue. We investigate this question further and use a planning-to-exchange task to study future planning in the cooperative domain in two species of monkeys: the brown capuchin (Cebus apella) and the Tonkean macaque (Macaca tonkeana). The rationale required subjects to plan for a future opportunity to exchange tokens for food by collecting tokens several minutes in advance. Subjects who successfully planned for the exchange task were expected to select suitable tokens during a collection period (5/10?min), save them for a fixed period of time (20/30?min), then take them into an adjacent compartment and exchange them for food with an experimenter. Monkeys mostly failed to transport tokens when entering the testing compartment; hence, they do not seem able to plan for a future exchange with a human partner. Three subjects did however manage to solve the task several times, albeit at very low rates. They brought the correct version of three possible token types, but rarely transported more than one suitable token at a time. Given that the frequency of token manipulation predicted transport, success might have occurred by chance. This was not the case, however, since in most cases subjects were not already holding the token in their hands before they entered the testing compartment. Instead, these results may reflect subjects' strengths and weaknesses in their time-related comprehension of the task.     

Assessing Working Memory Capacity Through Time-Constrained Elementary Activities

Working memory (WM) capacity measured through complex span tasks is among the best predictors of fluid intelligence (Gf). These tasks usually involve maintaining memoranda while performing complex cognitive activities that require a rather high level of education (e.g., reading comprehension, arithmetic), restricting their range of applicability. Because individual differences in such complex activities are nothing more than the concatenation of small differences in their elementary constituents, complex span tasks involving elementary processes should be as good of predictors of Gf as traditional tasks. The present study showed that two latent variables issued from either traditional or new span tasks involving time-constrained elementary activities were similarly correlated with Gf. Moreover, a model with a single unitary WM factor had a similar fit as a model with two distinct WM factors. Thus, time-constrained elementary activities can be integrated in WM tasks, permitting the assessment of WM in a wider range of populations.     

Maternal Uniparental Isodisomy Causing Autosomal Recessive GM1 Gangliosidosis: A Clinical Report

Uniparental disomy is a genetic cause of disease that may result in the inheritance of an autosomal recessive condition. A child with developmental delay and hypotonia was seen and found to have severely abnormal myelination. Lysosomal enzyme testing identified an isolated deficiency of beta-galactosidase. Subsequently, homozygous missense mutations in the galactosidase, beta 1 (GLB1) gene on chromosome 3 were found. Parental testing confirmed inheritance of two copies of the same mutated maternal GLB1 gene, and no paternal copy. SNP analysis was also done to confirm paternity. The patient was ultimately diagnosed with autosomal recessive GM1 gangliosidosis caused by maternal uniparental isodisomy. We provide a review of this patient and others in which uniparental disomy (UPD) of a non-imprinted chromosome unexpectedly caused an autosomal recessive condition. This is the first case of GM1 gangliosidosis reported in the literature to have been caused by UPD. It is important for genetic counselors and other health care providers to be aware of the possibility of autosomal recessive disease caused by UPD. UPD as a cause of autosomal recessive disease drastically changes the recurrence risk for families, and discussions surrounding UPD can be complex. Working with families to understand UPD when it occurs requires a secure and trusting counselor-family relationship.     

Long-tailed macaques display unexpected waiting abilities in exchange tasks

The ability of animals to delay gratification is crucial for complex goal-directed action. It may help them in making effective decisions when facing a choice. We tested the ability of nine long-tailed macaques (Macaca fascicularis) to delay gratification in several experiments. In exchange tasks, subjects had to keep a small piece of cookie before returning it to an experimenter in order to get a larger food amount. Results showed that animals could wait between 10 s and 10 min depending on individual and sizes of reward. In another experiment, subjects could immediately give back the initial piece of cookie then wait for the return. Their performances more than doubled, demonstrating the role of consumption inhibition in postponing gratification. Such achievements underscore delays of gratification which until now were not thought possible in monkeys. Finally, subjects were presented with an accumulation of food pieces added at short intervals until they seized them. They mostly waited between 30 s and 1 min, which points at the consistency of our data, compared to those of other studies. Our results indicate that long-tailed macaques anticipated the duration of delays. We may account for their remarkable performances by their achievements in the social context.     

Identity,past and present,in an historical child-care setting

This article puts into context the service offered today to adults (former pupils) who grew up in the care of the Foundling Hospital. Key issues referred to are attachment, loss, identity and the urge to reconnect with one's personal history. Reflections on these issues are based on the experience of Coram Family social workers, who have for the past thirty years provided a birth-record service to the former pupils of the Foundling Hospital and their descendants. It is a moving experience to hear from this group of individuals something of what it has meant to have grown up in such particular circumstances. Although there are many echoes with adoption and fostering today, other significant issues are raised which do not apply in the work of family placement as it is now practised. Some historical background is given below in order to set the scene for this unique piece of child-care history, also to allow examination of the challenges faced by some 20,000 children over 200 years, in recognition of which the service to those former pupils and their families is still offered.     

Which processes are involved in cognitive procedural learning?

Procedural memory is characterised by a relative resistance to pathology, making its assessment of the utmost importance. However, few studies have looked at the cognitive processes involved in cognitive procedural learning. In an initial experiment, we studied the role of different cognitive functions in massed cognitive procedural learning. Our results confirmed the existence of three separate learning phases and, for the first time, demonstrated the involvement of episodic memory and executive functions in the first learning phase. In a second experiment, we studied the effect of distributed learning conditions on the dynamics of procedural learning. This second study confirmed our results but showed that these conditions slow down the process of cognitive procedural learning. Our overall findings call into question the status of functionally autonomous memory system that is currently allotted to procedural memory, and suggest that the role of nonprocedural cognitive components should be taken into account in patient rehabilitation.     

Metacognition,Executive Functions and Aging: The Effect of Training in the Use of Metacognitive Skills to Solve Mathematical Word Problems

The aim of our research was to study the effects of metacognition training on the performance of older adults solving mathematical word problems. A further aim was to study the links between metacognition and executive function. Thirty-two subjects aged over 60, divided into an experimental and a control group, took part in this study which involved five training sessions. Results show that metacognition training enhanced the two metacognition components (knowledge and skills) and the mathematical problem-solving capacities of the participants. They also suggest that the use of metacognition by older people to solve mathematical word problems is supported by executive functions (updating, shifting) and particularly by processing speed.     

Gouvernance et éthique cliniques : deux outils complémentaires pour une meilleure coordination des soins et des traitements

“Governance”, “ethics” and “clinical” three words for a same goal: protect the human health. “Corporate governance” must be associated with the new theory of the firm, for which the theory of asymmetric information provides the foundations. Indeed problems of information represent a fundamental change in the prevailing paradigm within economics; they are central to understanding political economy. “Clinical governance”, promoted by the UK government, constitutes an overarching mechanism designed to improve clinical quality in the National Health Service. To the medical establishment, it is a means to improve the quality of medical practice through clinical guidelines. To make a significant impact on the improvement of healthcare quality, the principles of clinical governance must produce synergy by involving professionals in the modernization of the organization. To obtain excellence in heath care, collective actions and shared decision making were essential. In this context, Clinical ethics consultations could provide a structured approach to decision making that could assist heath professional to resolve conflicts or ethical problems that arise in the care of particular patients.
