Whether the format of a recognition memory task influences the contribution of recollection and familiarity to performance is a matter of debate. The authors investigated this issue by comparing the performance of 64 young (mean age = 21.7 years; mean education = 14.5 years) and 62 older participants (mean age = 64.4 years; mean education = 14.2 years) on a yes–no and a forced-choice recognition task for unfamiliar faces using the remember– know–guess procedure. Familiarity contributed more to forced-choice than to yes–no performance. Moreover, older participants, who showed a decrease in recollection together with an increase in familiarity, performed better on the forced-choice task than on the yes–no task, whereas younger participants showed the opposite pattern.

This study examined the performance of normal controls (NC) and Alzheimer's disease (AD) patients on free recall, semantic cued recall and object cued recall of both subject-performed tasks (SPTs) and verbal descriptions of actions, by controlling familiarity of actions associated to objects. The results showed that both groups performed better after SPT encoding than after verbal encoding. in all three types of recall. In addition, this SPT advantage was greater for AD patients than for NC in the object cued recall test, emphasizing AD patients' sensibility to the congruence of cues between encoding and retrieval conditions. Following verbal encoding. NC showed a better recall for less familiar actions than for highly familiar actions, whereas AD patients exhibited the opposite pattern. These results reflect that AD patients did not benefit from a distinctiveness effect at encoding for improving subsequent retrieval of verbal information, probably due to a reduced level of elaboration during encoding. However, there was no effect of action familiarity on recall performance by both groups following SPT encoding. These results suggest that memory for verbal actions and SPTs is governed by different principles. In addition. they demonstrate the robustness of the SPT effect in AD patients, who were able to improve memory performance in the SPT condition not only with highly familiar actions but also with less familiar actions.

The mobile phone may be useful to keep in contact with spatially disoriented and memory impaired patients. In keeping with this idea, this study describes the training program developed to teach two patients with mild Alzheimer's disease (CI and ML) how to use their own mobile phone. Each training session was divided into two parts. In the first part, the spaced-retrieval technique was used to promote the consultation of a card pasted on the back of the phone. The card detailed each stage of phone utilization and which keys had to be pressed to call somebody. In the second part, the patients received repetitive exercises of calling based upon the errorless learning principle. At the end of three-months rehabilitation, the results showed different learning patterns for the patients. ML needed more spaced-retrieval sessions to spontaneously consult the card and to correctly use the phone, compared to CI However, by the repetition of calling exercises, both patients showed a decrease of instruction card consultation, whereas they were still able to correctly call somebody. This learning ability is hypothesized to be a consequence of a relatively preserved procedural memory in both patients. In conclusion, this study highlights the effectiveness of combined specific learning techniques for improving AD patient's autonomy in daily life activities. [less ▲]

Lexicality and phonotactic frequency effects are observed in many cognitive studies on language processing, but little is known about their underlying neural substrates, especially with regard to phonotactic frequency effects. Here, we conducted a positron emission tomography (PET) study in which 11 right-handed volunteers had either to repeat or to listen to lists of words, high phonotactic frequency nonwords, and low phonotactic frequency nonwords. The comparison of word versus nonword processing consistently confirmed previous findings of left temporal and prefrontal activations classically ascribed to lexicosemantic processing. Higher activation was found in the right posterior superior temporal gyrus when comparing high phonotactic frequency nonwords to words, but not when comparing low phonotactic frequency nonwords to words. We propose that this region is implicated in the formation of temporary phonological representations for high-probability phonological events, which may support processing of high phonotactic frequency nonwords [less ▲]

This review presents neuroimaging studies which have explored the cerebral substrates of the central executive component of the working memory model proposed by Baddeley and Hitch [working memory (1986); Recent advances in learning and motivation (1974)]. These studies have demonstrated that different executive functions (manipulating and updating of information, dual-task coordination, inhibition and shifting processes) not only recruit various frontal areas, but also depend upon posterior (mainly parietal) regions. Such results are in agreement with the hypothesis that executive functions rely on a distributed cerebral network not restricted to anterior cerebral areas. Moreover, the intervention of similar prefrontal regions in a large number of executive tasks suggests that the central executive functioning must be understood in terms of different interactions between a network of regions rather than in terms of a specific association between one region and one higher-level cognitive process [less ▲]

We investigated the mere exposure effect and the explicit memory in Alzheimer's disease (AD) patients and elderly control subjects, using unfamiliar faces. During the exposure phase, the subjects estimated the age of briefly flashed faces. The mere exposure effect was examined by presenting pairs of faces (old and new) and asking participants to select the face they liked. The participants were then presented with a forced-choice explicit recognition task. Controls subjects exhibited above-chance preference and recognition scores for old faces. The AD patients also showed the mere exposure effect but no explicit recognition. These results suggest that the processes involved in the mere exposure effect are preserved in AD patients despite their impaired explicit recognition. The results are discussed in terms of Seamon et al.'s (1995) proposal that processes involved in the mere exposure effect are equivalent to those subserving perceptual priming. These processes would depend on extrastriate areas which are relatively preserved in AD patients. [less ▲]

The aim of this study was to examine the hypothesis of a link between frontal cortex and two executive functions in working memory: the capacity to perform a dual task and the ability to inhibit irrelevant information. A dual task designed to assess the capacity to perform storage and processing simultaneously and a directed forgetting task designed to assess the capacity to actively inhibit no-longer relevant information were administered to a group of patients with focal frontal lesions and to a group of control participants. The results revealed that despite showing reduced short-term storage, frontal patients performed the dual task and inhibited the no-longer relevant information as well as control participants. These findings suggest that not all-executive processes are exclusively sustained by the frontal cortex [Quart J Exp Psychol 9 (1996) 5; Curr Opin Neurobiol 10 (2000) 195; Neuropsychology (1994) 544; The Cognitive Neuropsychology of Alzheimer-type dementia.

Introduction Chez l’adulte, il est classiquement observé que l’exposition répétée à des stimuli conduit à un accroissement de la préférence pour ces derniers en comparaison à de nouveaux stimuli (Effet de simple exposition, ESE; [1]). En revanche, un grand nombre d’études [2] montrent chez l’enfant un effet inverse suggérant une préférence pour la nouveauté. Le but de cette étude est d’utiliser le paradigme de simple exposition chez des enfants de différentes tranches d’âge afin de déterminer la période durant laquelle la préférence pour la nouveauté s’inverse et est remplacée par la préférence pour la familiarité. Participant 16 enfants (de 5 à 6 ans et de 7 à 8 ans), 22 enfants (de 9 à 10 ans), et 17 enfants (de 11 à 12 ans) et 16 jeunes adultes (de 18 à 30 ans). Matériel Dans la phase d’encodage, les sujets évaluent l’orientation (droite/gauche) de 12 figures tridimensionnelles présentées 5 fois durant 2,5 secondes. Lors de la phase test, le sujet est soumis à deux tâches de jugement à choix forcés (préférence et reconnaissance) sur 12 paires d’objets tridimensionnels nouveaux-familiers. Les deux jugements se portent sur les mêmes items et leur ordre de passation est contrebalancés entre les sujets. Résultats et Discussion Un effet de préférence différent du hasard est observé chez les adultes (P<.05) dans le sens d’une préférence pour les stimuli préalablement exposés (ESE), mais non chez les enfants (Ps>.1). Pourtant, lorsque l’on examine les relations entre préférence et reconnaissance, on constate que les enfants de 5/6 ans ont tendance à préférer les nouvelles figures et non les figures préalablement exposées et reconnues (Chi-carré= -.15, p=.05). En revanche, cette tendance s’inverse au cours du développement, et ce, dès 11/12 ans où les enfants tendent à préférer les stimuli préalablement exposés et reconnus (Chi-carré=.17, p=.02). Ce choix de préférence pour les stimuli familiers persistent chez les jeunes adultes (p<.05). Notre étude montre que les plus jeunes enfants ont tendance à préférer les nouveaux stimuli alors que les jeunes adultes préfèrent les stimuli familiers quand on compare leurs choix de préférence à leur performance en reconnaissance. A partir de 11-12 ans, les enfants montrent le pattern inverse indiquant un « shifting » de la préférence pour la nouveauté vers la préférence pour la familiarité. Ces données montrent que les scores en reconnaissance influencent différemment la préférence en fonction de l’âge. [less ▲]

Using Positron Emission Tomography (PET), we investigated cerebral regions associated with the episodic recognition of words alone and words bound to contextual colours. Two modes of colour encoding were tested: incidental and intentional word-to-colour binding. Word-only recognition was associated with brain activation in a lexico-semantic left middle temporal region and in the cerebellum following an incidental colour encoding, and with brain activation in the left posterior middle frontal gyrus, right anterior cingulate and right inferior frontal gyrus following an intentional encoding. Recognition of bound features was associated with activation in left prefrontal and superior parietal regions following an incidental colour encoding, and with preferential right prefrontal cortex activation following an intentional colour encoding. Our results are in line with the hypothesis of a parietal involvement in context processing, and prefrontal areas in monitoring retrieval processes. Our results also support the hypothesis of a 'cortical asymmetry for reflective activity' (CARA). [less ▲]
