There exists a large inter-individual variability regarding the effects of aging on cognition. According to Stern (2009), people who developed a high level of reserve are more resilient to the effects of aging that individuals with lower cognitive reserve. In this study, we describe the impact of cognitive reserve on executive functions in normal aging. Ninety healthy participants aged from 60 to 80 years were recruited. We assessed the three major executive functions: Inhibition (Stroop test, Hayling test, TAP Incompatibility subtest), Shifting (TAP Flexibility subtest, Plus-Minus task), and Updating (Letter-Number Sequencing subtest from MEM III, Letter memory task, 2-back task). Cognitive reserve was measured by questionnaires assessing educational level, occupation, leisure activities and physical activity across the life. Multiple linear regressions (p<0.05) adjusted for age, quality of sleep, processing speed showed that elderly with a high level of reserve have better performance on updating. We also assessed the effect of each factor of cognitive reserve separately after adjustment for the other. We observed that people with high level of education have better performance on flexibility (TAP Flexibility subtest and composite score) and on updating (Letter-Number Sequencing subtest, Letter memory and composite score). However, we didn’t observe any significant effect of the other factors of cognitive reserve. These results suggest that the cognitive reserve is related to abilities in some executive tests.

It is now acknowledged that there exists a large inter-individual variability in age-related cognitive changes. According to Stern (2009), the cognitive reserve built up throughout the life span will make seniors more or less resilient to the deleterious effects of aging on cognition, with seniors having a high level of cognitive reserve being more prone to successfully cope with cognitive and neuronal changes. Currently, few studies have focused on the specific effects of different factors of cognitive reserve on cognition. Consequently, the objective of this study is to determine the impact of four determinants of cognitive reserve on executive functions in normal aging. Sixty-eight healthy participants aged 60 to 80 were enrolled. Regarding executive functions, Inhibition (Stroop test, Hayling test, TAP Incompatibility subtest), Shifting (TAP Flexibility subtest, Plus-Minus task), and Updating (Letter-Number Sequencing subtest from MEM III, Letter memory task, 2-back task) were assessed (Miyake et al., 2000). Cognitive reserve was measured by questionnaires assessing educational level, occupation, leisure activities and physical activity. Moreover, an accelerometer allowed quantitative measure of physical activity by recording body movements during two weeks. Group comparisons (p<0.05) showed that seniors with a high level of cognitive reserve (measured by a global composite z-score) have better updating abilities (Letter memory task and updating composite score). In order to test the influence of each cognitive reserve factor on executive functions, simple linear regressions (p<0.05) were performed. The results showed that the educational level accounts for a significant part of the variance in flexibility (TAP Flexibility) and updating (Letter-Number sequencing, 2-back and composite score). The occupational level accounts significantly for the variance of the updating composite score. Regarding the quantitative physical activity, the mean number of minutes per day in moderate or intense physical activity significantly predicted the updating composite score. These results indicate that the level of cognitive reserve is related to abilities in some executive tests, particularly updating abilities. Importantly, all aspects of cognitive reserve are not associated with the three executive processes. This indicates a specificity of the protective effect of cognitive reserve on executive abilities.

A l’heure de la révision du permis de lotir en Région wallonne, le beeldkwaliteitplan utilisé aux Pays-Bas pour encadrer la création de nouveaux quartiers constitue une référence intéressante. Cet outil de composition s'appuie sur un partenariat entre le public et le privé et donne la priorité à la conception urbanistique des projets. A l'inverse des permis de lotir wallons, le beeldkwaliteitplan se concentre en effet sur les espaces publics et les interfaces entre sphères privées et publiques. L'article propose d'examiner cet outil urbanistique à travers l'analyse de deux projets à Maastricht. [less ▲]

Après avoir brièvement décrit le contexte général du CAPAES en FWB, nous présentons le dispositif de formation en didactique professionnelle des langues modernes à l'ULg, en nous concentrant principalement sur l'accompagnement individualisé des étudiants-enseignants assisté par la vidéo (autoscopie). Nous fournissons ensuite quelques éléments d'évaluation de ce dispositif de formation basés sur nos observations et sur deux types d'enquêtes (questionnaires et entretiens semi-structurés). Enfin, sur la base de cette évaluation croisée, nous proposons quelques pistes pour optimiser le dispositif actuel. [less ▲]
