Si le profil langagier des personnes trisomiques 21 est actuellement bien connu, l'étude du profil mnésique est quant à lui en plein essor. Les premières études à ce propos datent des années soixante et mettent en évidence un déficit de la mémoire auditive à court terme chez les déficients mentaux alors que les performances en mémoire visuelle à court terme semblent relativement préservées. L'empan de mémoire phonologique à court terme des personnes trisomiques 21 est réduit par rapport à ce qu'il devrait être sur la base de l'âge chronologique et de l'âge mental (puisqu'il ne dépasse pas, et ce même à l'âge adulte, celui d'un enfant normal de 4 ans). L'élévation de cet empan n'est pas lié, chez les personnes trisomiques 21, à l'élévation de l'âge chronologique mais seulement à l'élévation de l'âge mental. La présence d'un effet de similarité phonologique et d'un effet de longueur des mots attestent la similarité de fonctionnement de la mémoire verbale à court terme chez les personnes trisomiques 21 et les enfants normaux. Les problèmes rencontrés par les personnes trisomiques 21 dans les tâches de mémoire à court terme verbale pourraient être dus à un déficit au niveau du processus de récapitulation subvocale. Cette hypothèse a conduit plusieurs équipes de recherche à tenter d'améliorer par le biais d'un entraînement ciblé de la stratégie de récapitulation. Les résultats de ces études mettent tous en évidence que les performances des personnes trisomiques 21 peuvent être améliorées par un entraînement spécifique de la stratégie de récapitulation.

We explored the effects of aging on memory for the temporal context, assessed by a list discrimination task with unfamiliar faces. In a first experiment, we compared incidental and intentional encoding of the temporal context in young and older adults. The results indicated that list discrimination performance declines with aging. Moreover, intentional encoding of the temporal context does not improve performance of neither group, compared to incidental encoding. In a second experiment, each list was associated with a different encoding context. The results showed age differences on list discrimination performance when participants tried to remember the encoding context of the items as a cue to retrieve their list of occurrence. However, there is no age difference when participants relied on some other processes, mainly involving the assessment of the strength of the memory for the item. The difficulty of older adults to use a reconstruction process may be partly due to a less efficient encoding of the contextual information necessary to reconstruct the temporal context of the event.

According to the dual-process recognition models, the retrieval of information from long-term memory is supported by recollection and familiarity. Alzheimer’s disease is consistently found to affect recollection. As for familiarity, however, no consensus has been reached so far. Some studies are in favor of an early impairment of familiarity, while others are in favor of a preservation of familiarity in the mild and moderate stages of the disease. This lack of consensus can be partly explained by methodological differences between studies. We discuss three methodological dimensions: the type of recognition test, the type of paradigm for estimating familiarity and recollection, and the nature of the material used. These differences reveal the complex nature of familiarity which would be underlied by different mechanisms that may be selectively altered or preserved in the disease. [less ▲]

Impaired memory performance does not constitute the prominent deficit in frontotemporal dementia (FTD). Nevertheless, it has been suggested that some specific aspects of memory may be disrupted in FTD patients, in particular, the ability to consciously recollect the context in which information has been learned (Simons et al., 2002). The aims of the current study was to investigate the states of awareness accompanying recognition memory by asking participants to make Remember/Know/Guess judgments. Concretely, 12 FDT patients and 12 matched healthy participants studied 20 word pairs. During cued recall, each trial consisted of one word from a pair and participants had to try to recall the associated word. Finally, a 5-alternative forced-choice recognition task was given and participants had to say whether they chose a word because they recollected the study context (Remember), they knew they saw the word, without recalling anything else (Know) or they guessed (Guess). Results from the cued recall and recognition parts indicated that FTD recalled less word pairs than the controls, but had similar levels of recognition performance. Nevertheless, FTD patients gave less Remember responses than the controls, and tended to give more Guess responses. To conclude, episodic memory performance in FTD was characterised by impaired self-initiated memory retrieval processes. Although global recognition memory performance was preserved, FTD patients’ memories lacked of autonoetic consciousness and were mainly based on familiarity judgments and guessing. This pattern of results is similar to that found in patients with focal frontal lobe lesions (e.g., Wheeler et al., 1995; Wheeler & Stuss, 2003) and is consistent with the idea that the memory dysfunctions observed in FTD may stem from damage to the prefrontal cortex.
