Le but de cette étude était double : d’une part, explorer les effets du vieillissement sur la recollection et la familiarité, et d’autre part, comparer deux procédures permettant de tester la reconnaissance (les procédures de type oui-non et à choix forcé). Nous avons administré un test de reconnaissance oui-non et un test de reconnaissance à choix forcé à 64 sujets jeunes (âge moyen : 21.73  2.36 ans) et à 64 sujets âgés (âge moyen : 64.36  3.03). Le matériel était composé de photos de visages d’hommes non familiers. Lors de la phase de reconnaissance, les sujets devaient préciser pour chaque visage reconnu s’il « se souvenait », « savait » ou « devinait » avoir vu le visage (Gardiner, Java, & Richardson-Klavehn, 1996). Les résultats ont montré un effet du vieillissement sur la proportion d’items correctement reconnus dans la tâche oui-non (F(1,124)=7.72, p<0.01), mais pas dans la tâche à choix forcé (F(1,126)=0.94, p=0.33). Par ailleurs, comparativement aux sujets jeunes, les sujets âgés donnaient moins de réponses « je me souviens » (p<0.01 dans la tâche oui-non et p=0.051 dans la tâche à choix forcé) et plus de réponses « je sais » (p=0.078 dans la tâche oui-non et p<0.0005 dans la tâche à choix forcé). Ces résultats confirment les données d’autres études (par exemple, Parkin et Walter, 1992). En ce qui concerne la contribution de la recollection et de la familiarité selon la procédure de test utilisée, les sujets jeunes avaient tendance à utiliser davantage de réponses « je me souviens » dans la tâche oui-non que dans la tâche à choix forcé (p=0.09). Dans les deux groupes d’âge, il y avait plus de réponses « je sais » et « je devine » dans la tâche à choix forcé que dans la tâche oui-non. Ces résultats semblent indiquer que la contribution des deux processus de la reconnaissance serait influencée par le type de procédure utilisé. [less ▲]

The aim of our study was twofold : to explore the effect of aging on recollection and familiarity and to compare two procedures for testing recognition (the yes-no and forced choice procedures). We administered a yes-no and a forced choice recognition task using unfamiliar faces as material to 32 young subjects (mean age: 23) and 32 older adults (mean age: 64.28). During the recognition phase, participants were asked to classify each recognised item as one that evoked a Remember response, a Know response or a Guess response. The results indicated significant age differences on global performance in the yes-no recognition task, but not in the forced choice task. Moreover, older adults gave less Remember responses and slightly more Know responses than young subjects. Our findings are consistent with previous studies indicating a reduction of recollection with aging. Concerning the contribution of recollection and familiarity to recognition as a function of the test format, participants in each age group used more Remember responses in the yes-no task than in the forced choice task and more Know responses in the forced choice than in the yes-no task. Our results seem to support the assumption that the contribution of recollection and familiarity depends on the type of testing procedure. [less ▲]

This PET study is concerned with the what, where, and how of implicit sequence learning. In contrast with previous studies imaging the serial reaction time (SRT) task, the sequence of successive locations was determined by a probabilistic finite-state grammar. The implicit acquisition of statistical relationships between serially ordered elements (i.e., what) was studied scan by scan, aiming to evidence the brain areas (i.e., where) specifically involved in the implicit processing of this core component of sequential higher-order knowledge. As behavioural results demonstrate between- and within-subjects variability in the implicit acquisition of sequential knowledge through practice, functional PET data were modelled using a random-effect model analysis (i.e., how) to account for both sources of behavioural variability. First, two mean condition images were created per subject depending on the presence or not of implicit sequential knowledge at the time of each of the 12 scans. Next, direct comparison of these mean condition images provided the brain areas involved in sequential knowledge processing. Using this approach, we have shown that the striatum is involved in more than simple pairwise associations and that it has the capacity to process higher-order knowledge. We suggest that the striatum is not only involved in the implicit automatization of serial information through prefrontal cortex-caudate nucleus networks, but also that it plays a significant role for the selection of the most appropriate responses in the context created by both the current and previous stimuli, thus contributing to better efficiency and faster response preparation in the SRT task.

The function of rapid-eye-movement (REM) sleep is stiil unknown. One prevailing hypothesis suggests that REM sleep is important in processing memory traces. Here, using positron emission tomography (PET) and regional cerebral blood flow measurements, we show that waking experience influences regional brain activity during subsequent sleep. Several brain areas activated during the execution of a serial reaction time task during wakefulness were significantly more active during REM sleep in subjects previously trained on the task than in non-trained subjects. These results support the hypothesis that memory traces are processed during REM sleep in humans. [less ▲]

We describe the case of a 58-years-old right-handed women suffering from an occipital-parietal lesion. The administration of a cognitively based assessment tool for limb praxis (Batterie d'Evaluation des Praxies, B.E.P., Peigneux and Van der Linden, 1998) demonstrated bilateral visuo-imitative apraxia. Gesture production was mainly characterised by spatial, errors, and imitation of meaningful gestures was worse than their pantomime on verbal command. Moreover, the imitation of meaningless gestures and their reproduction on a manikin were worse than imitation of their matched meaningful gestures. In a cognitive perspective, adapted from the Rothi et al. (1997) and Goldenberg (1995) contributions to our understanding of limb praxis, this configuration of performance suggests deficits occurring at multiple levels. On one hand, it suggests either access difficulties or alteration of the output praxicon, i.e., the lexicon for visuo-kinesthetic engrams of meaningful gestures. On the other hand, the simultaneous deficit for meaningless gesture reproduction on the subject's own body and on a manikin favors an alteration of the structural descriptions of the human body (i.e., human body knowledge), underlying the mental transposition processes occurring between the visual analysis of a meaningless gestural configuration and its effective reproduction on oneself or on a manikin, thus contradicting the classic view of a direct pathway linking visual analysis and motor planning in meaningless gesture imitation. Finally, due to the output praxicon deficit, imitation of meaningful gestures is partly processed in the same way as meaningless gestures (also impaired in this case), leading to an interference effect between both degraded memory-based and visually-transposed traces, which account for imitation of meaningful gestures being worse than their pantomime on verbal command. We also assess regional cerebral metabolism using positron emission tomography (PET). Comparison with 41 healthy subjects (SPM96) demonstrated a statistically significant hypometabolism in the left intraparietal sulcus and superior parietal lobule, and in the right dorsal prestriate cortex. These results, together with a review of the other studies of visuo-imitative apraxia, suggest that the left intraparietal sulcus may be associated with access or integration of information from the output praxicon. The left superior parietal and the right dorsal prestriate deficits functionally impaired a bilateral dorsal network implied in the mental transformations of the body, thus suggesting that these mental transformations are underlined by knowledge of the human body, which may subsequently explain the deficit for the reproduction of meaningless and meaningful configurations.

We examined different views of the relationships between working memory, long-term memory and language processing : working memory considered as a gateway between sensory input and long-term memory or rather as a workspace; working memory considered as not strictly tied to any particular cognitive system (and consequently viewed as separated from the language system) or rather as drawing on the operation and storage capacities of a subset of components involved in language processing. It is argued that functional imagery studies (along with neuropsychological researches) could contribute to decide between these conceptions. [less ▲]
