These results suggest that in community-dwelling elders, GAD is the main anxiety disorder associated with poor global cognitive functioning. Moreover, this association is modified by sex, but not by the presence of depressive episodes.

International audienceObjectives: In the context of rehabilitation, the use of new technology such as Virtual Reality Technology (VRT) offers multiple possibilities to modulate the functional stimulation of subjects according to needs.Material and methods: In this study, the validity and reliability of our VRT system were investigated in fifteen healthy aged adults (HAA) and seven aged subjects with mild cognitive impairment (MCI). One implicit session was designed through two virtual environments (VEs) in order to induce the adapted activities associated with balance and postural control. In comparison, the same activities were achieved in explicit sessions with a physiotherapist. This cross-over study made use of a qualitative method to collect participants' feelings in both implicit and explicit sessions.Results: The results allowed us to validate the embedded technologies in our system and also the VE features for MCI subjects and their healthy counterparts. The analysis of participants' feelings showed that implicit tasks were preferred to explicit ones.Conclusion: This study highlighted that the use of VRT generated a competitive spirit in all participants. This point underlines the major role of reward motivation in motor learning processes in rehabilitation

Performance on verbal memory tests is generally associated with socio-demographic variables such as age, sex, and education level. Performance also varies between different cultural groups. The present study aimed to establish normative data for the Rappel libre/Rappel indicé à 16 items (16-item Free and Cued Recall; RL/RI-16), a French adaptation of the Free and Cued Selective Reminding Test (Buschke, 1984; Grober, Buschke, Crystal, Bang, & Dresner, 1988). The sample consisted of 566 healthy French-speaking older adults (50-88 years old) from the province of Quebec, Canada. Normative data for the RL/RI-16 were derived from 80% of the total sample (normative sample) and cross-validated using the remaining participants (20%; validation sample). The effects of participants' age, sex, and education level were assessed on different indices of memory performance. Results indicated that these variables were independently associated with performance. Normative data are presented as regression equations with standard deviations (symmetric distributions) and percentiles (asymmetric distributions).
