Studies of manual and digital sequence learning indicate that motor memories continue to be processed after training has ended, following a succession of identifiable steps. However, it is not known whether this offline memory processing constitutes a basic feature of motor learning and generalizes to the implicit learning of a sequence of eye movements. To assess this hypothesis, we have created the serial oculomotor reaction time task (SORT). Participants were trained to the SORT then tested after either 30 min, 5 h or 24 h. During training, ocular reaction times decreased monotonically over practice of a repeated sequence, then increased when a different sequence was displayed, demonstrating oculomotor learning of the trained sequence. When tested 30 min after training, a significant gain in oculomotor performance was observed irrespective of the sequence learning. This gain was no longer present after 5 h. Remarkably, a gain in performance specific to the learned sequence emerged only 24 h after training. After testing, a generation task confirmed that most subjects learned implicitly the regularities of the sequence. Our results show that, as for manual or digital sequences, oculomotor sequences can be implicitly learned. The offline processing of oculomotor memories follows distinct stages in a way similar to those observed after manual or digital sequence learning. (c) 2006 Elsevier B.V. All rights reserved.

The main purpose of the present study was to examine whether implicit learning abilities, assessed by means of a serial reaction time task, are present to the same extent in 6- and 10-year-old children as in adults. We also wondered whether the knowledge acquired after one learning session is retained after a one-week delay. And finally, we studied the explicit knowledge developed by the children in this task. Our results show no age-related difference in the serial reaction time performance, which is consistent with the idea that implicit learning abilities may be efficient early in development. [less ▲]

Implicit/explicit memory dissociation in Alzheimer's disease: the consequence of inappropriate processing?

Dual-process theories of recognition posit that perceptual fluency contributes to both familiarity-based explicit recognition and perceptual priming. However, the priming-without-recognition dissociation, as observed through the intact mere exposure effect and impaired recognition in patients with Alzheimer's disease (AD), might indicate that familiarity and perceptual priming are functionally distinct. This study investigated whether the AD patients' processing strategies at testing may explain this priming-without-recognition dissociation. First, we replicated the priming-without-recognition effect in 16 patients who exhibited intact exposure effects despite null recognition. Second, we showed that, under identical conditions, inducing a holistic processing strategy during recognition testing increased AD patients' recognition--performance was similar for AD patients and healthy control participants. Furthermore, prompting analytic processing during both priming and recognition tasks decreased AD patients' performance in both tasks. These findings suggest that the extent to which AD patients use perceptual fluency in priming and recognition tasks is contingent on their processing approach. The choice of processing strategy may depend on how difficult patients perceive the task to be. [less ▲]

S’il est unanimement admis que le traitement de l’hypertension artérielle améliore le pronostic cardiovasculaire des patients qui en sont atteints, force est de constater que la moitié des patients traités n’ont pas leur pression artérielle normalisée. Un des facteurs responsables de ce relatif échec est la mauvaise adhésion au traitement (non médicamenteux et pharmacologique). Ce problème d’observance est multifactoriel. Interviennent le patient, sa maladie, son traitement et l’environnement thérapeutique où la relation médecin-malade joue un grand rôle. Pour améliorer l’observance, comme d’ailleurs la persistance du traitement, il faut d’abord y penser. Le dialogue avec le patient sur l’observance doit être mené à chaque consultation. Une excellente relation médecin-patient, une éducation sur l’hypertension, ses risques et les moyens d’éviter les complications, le choix de schémas de traitement bien tolérés, simplifiés et introduits progressivement, la recherche et la limitation des effets secondaires générés, le partenariat de la famille et du pharmacien dans la prise en charge, la stimulation de l’automesure de la pression artérielle par le patient sont autant de pistes importantes pour améliorer ce paramètre. Ceci permettrait, à coup sûr, de réduire les complications cardiovasculaires liées à l’hypertension et le coût pour la société. [less ▲]
