Given that both explicit and implicit retrieval tend to occur in this type of memory task, conventional analyses of old/new event-related potential effects are equivocal.To overcome this problem, depth of processing was manipulated and subjective awareness measured. From 400 ms poststimulus, event-related potentials evoked by stems completed with studied words were more positive than those evoked by stems completed with unstudied items. This di¡erence was maximal at parietooccipital electrode sites. Event-related potentials were not modulated by either depth of processing or awareness. Behavioral and event-related potential data converged to indicate that the old/new e¡ect re£ects processes either contributing to, or contingent upon, implicit memory retrieval.

Alors que les troubles de l'attention sont frequemment decrits dans ce type de population, il semble que les tests directs d'attention issus de modeles theoriques distincts ne permettent pas de les reveler. C'est pourquoi nous avons choisi d'utiliser le test du K.ABC dont certaines epreuves sont sensibles aux processus attentionnels et qui est sous-tendu par un modele theorique coherent. Les resultats obtenus mettent en evidence des deficits cognitifs precis, presents chez tous les enfants et temoignant d'un trouble de l'attention.

Cinquante jeunes adultes et 41 adultes plus âgés ont appris une liste de mots non reliés sémantiquement et ont dû les rappeler successivement 3 fois, afin que nous puissions calculer un indice d’organisation subjective ( Pair Frequency , PF). Le niveau d’ouverture a été mesuré à l’aide de la version française du NEO-PI-R (BFI-Fr) du questionnaire de personnalité Big-Five. Les adultes âgés ont rappelé et organisé moins de mots que les adultes jeunes. L’ouverture était positivement corrélée avec le rappel pour les deux groupes et avec le PF uniquement dans le groupe le plus âgé. Le PF et l’ouverture expliquent de manière significative le rappel chez les jeunes adultes, tandis que chez les adultes plus âgés, seule l’ouverture explique le rappel. L’ouverture n’a contribué au PF que ...

A sample of 194 participants aged 21 to 80 divided into three age groups (21-40, 41-60, 61-80) completed the two strategy scales of the Metamemory in Adulthood (MIA) questionnaire, differentiating between internal and external everyday memory strategy uses, and three tests of executive functioning. The results showed that: (1) the use of external memory strategies increased with age, whereas use of internal memory strategy decreased; (2) executive functioning appeared to be related only to internal strategies, the participants who reported the greatest use of internal strategies having the highest executive level; and (3) executive functioning accounted for a sizeable proportion of the age-related variance in internal strategy use. These findings suggest that older adults preferentially use external memory strategies to cope with everyday memory impairment due to aging. They also support the view that the age-related decrease in the implementation of internal memory strategies can be explained by the executive hypothesis of cognitive aging. This result parallels those observed using objective laboratory memory strategy measures and then supports the validity of self-reported memory strategy questionnaire.

Our study aims at better understanding how ageing affects the driving abilities of elderly drivers in this situation. Three groups of drivers, young (25-35 years), younger-old (60-69 years), and older-old (70 and more) took part in the study. The experiment consisted in two parts. Perceptual, cognitive and motor abilities were assessed in the first one. The second one took place on a driving simulator. Participants had to decide if they could perform a left turn at intersections. Traffic conditions were varied. Statistical analysis showed the classical age-related perceptual, cognitive and physical declines. With regard to driving performance, elderly drivers accepted fewer left-turns than younger drivers, but exhibited more risky behaviors, especially when traffic was complex. Two patterns emerged from correlations between test results and driving behavior. Driving performances of young people showed that both their cognitive and perceptual abilities correlated with driving performances, but not their motor abilities. As for elderly people, cognitive and motor abilities were connected to driving performance, but not their perceptual abilities. Regressions are being processed in order to detail the relationships between the different variables. Results will determine the most relevant predictors of risky behaviors among elderly drivers at intersections.

The second aim was to prioritize clusters of abilities. We used an online questionnaire to survey 479 expert pilots and WSOs in order to assess the level of requirement of 33 cognitive, psychomotor, and perceptual abilities on a Likert-type scale. Two groups of abilities were identified: a common group and a specific one composed of abilities that are crucial for specific jobs. The prioritization of clustered abilities indicated differences in the level of requirement within the so-called crucial abilities. This study led to the identification of four specific profiles of ordered abilities.

To this end, we compared the relationship between the performance of young and older adults on two executive functioning tests and an updating working-memory task with different load levels. The results revealed a significant interaction between age, task demand, and individual executive capacities, indicating that executive resources were only involved at lower loads in older adults, and only at higher loads in young adults. Overall, the results are not consistent with the proposition that cognition places greater demand on executive control in older adults. However, they support the view that how much young and older adults rely on executive control to accomplish cognitive tasks depends on task demand. Finally, interestingly these results are consistent with the CRUNCH model accounting for age-related differences in brain activations.

Participants were divided into four groups based on age (young vs. older) and educational level (high vs. low), with 14 participants in each group. Event-related potentials (ERP) were recorded while participants performed a word-stem cued-recall task. Age-related memory deficits were greater for the less educated individuals. Age differences in the ERP old/new effects were also modulated by the level of education. This study demonstrated that the effects of age on episodic memory and ERP correlates of retrieval success are smaller in participants with high educational levels than those with lower levels. These findings provide support for the reserve hypothesis and highlight the need to consider individual differences when studying cognitive and cerebral changes in aging.

In the first trial, generation improved the memory performance of both young and older adults. However, in Trial 2, the generation effect remained significant for older adults only, confirming that they did not change the way they processed read items, unlike the young adults. The older adults were also less spontaneously aware that generation led to better memory performance in the first trial, and, in contrast to the young adults, awareness did not result in a reduction of the generation effect. Moreover, the agerelated differences in generation effect reduction were mediated by an independent measure of self-reported internal strategy use. However, when an appropriate environmental support was provided between both trials, older adults improved read items recall at the second trial as well as younger ones, leading to an elimination of the generation advantage for both groups. Environmental support reduced the implication of internal strategy use in the generation effect reduction, suggesting that age-related differences in the implementation of effective encoding processes in Trial 2 would be the consequence of a metamemory deficit, and reduced capacity to selfinitiate internal strategies.

Thus, the aim of the present study was to examine the possible protective effect of these two factors on the age-related decline in a cued-recall task. Four age groups of participants (20-39 years, 40-59 years, 60-74 years and 75-90 years) were administered with a word-stem cued-recall test to assess episodic memory, a "vocabulary" sub-test of the WAIS-R to assess knowledge and a reading span test to assess control. Results showed an age-related effect on the episodic memory, the control performance and the knowledge measure, indicating that performance decreases with age. A GLM analysis revealed a positive effect of the knowledge and the control factors on the cued-recall performance, and interaction between age and the knowledge factor resulting from a positive effect of the knowledge level only for the youngest group of participants (20-39 years). Furthermore, results revealed an interaction between age and the control factor, indicating a positive effect of the control level for the two oldest groups of participants (60-74 years and 75-90 years). These results suggest that, contrary to the knowledge, the control factor could be an effective protection against the age-related negative effects on the episodic memory.
