Associative visual agnosia is classically defined as normal visual perception stripped of its meaning [Archiv für Psychiatrie und Nervenkrankheiten 21 (1890) 22/English translation: Cognitive Neuropsychol. 5 (1988) 155]: these patients cannot access to their stored visual memories to categorize the objects nonetheless perceived correctly. However, according(More)
BACKGROUND Despite many studies demonstrating memory and executive impairments in young and old depressed patients, the relationships between age, executive functioning and memory have not been evaluated in depression. The aim of this study was to investigate if older patients were more vulnerable than younger patients to the impact of depression on memory(More)
This paper describes and evaluates a programme of neuropsychological rehabilitation which aims to improve three sub-components of the working memory central executive: processing load, updating and dual-task monitoring, by the acquisition of three re-organisation strategies (double coding, serial processing and speed reduction). Our programme has two(More)
This study explored the ability of a severe amnesic patient (AC) to acquire new vocabulary words. We compared AC's knowledge of words entered into the French lexicon during three different periods: before 1920, between 1965 and 1985, and after 1986 (i.e. after the onset of his amnesia). AC's knowledge was assessed by asking him to give, for each word, its(More)
The case of a 19-year old patient suffering of transient metamorphopsia restricted to familiar faces and familiar objects is reported. This clinical sign resulted from a small right occipitotemporal haemorrhage due to a sub-cortical metastasis. The patient claimed that faces are distorted and look more pleasant. There were neither visual field defects nor(More)
OBJECTIVE To assess the sensitivity of traditional neuropsychological tests and of a behavioral inventory of executive disorders in a large sample of patients with chronic severe traumatic brain injury. METHODS A total of 112 patients were compared with 780 healthy controls from a larger database. The GREFEX battery included 7 widely used tests and the(More)
Four age groups of normal subjects were given a visual reaction time task with three levels of uncertainty. The speed of response improved when the interval between the auditory warning signal and the imperative visual stimulus increased in the range from 1 to 3 s. This delay effect decreased when the level of uncertainty was increased, irrespective of the(More)
Wyns and Bruyer in 1988 proposed a visual attention test that is easy to use and sensitive both to the age of the subjects and the level of uncertainty about the response required. This test was designed as a fine gauge of attention deficits in brain-damaged subjects with poorly structured complaints. We present here a preliminary application of the test to(More)
