OBJECTIVE The 22q11.2 deletion syndrome (22q11DS) is a neurogenetic syndrome with high risk for the development of psychiatric disorder. There is interest in identifying reliable markers for measuring and monitoring socio-emotional impairments in 22q11DS during development. The current study investigated eye gaze as a potential marker during a(More)
We report a study on the spoken production of subject–verb agreement in number by four age groups of normally developing children (between 5 and 8;5) and a group of 8 children with Specific Language Impairment (SLI; between 5;4 and 9;4), all French speaking. The production of verb agreement was experimentally elicited by asking children to complete sentence(More)
Deficits in memory consolidation have been reported in adult patients with epilepsy but, not to our knowledge, in children. We report the long-term follow-up (9 y. o. to 18 y. o.) of a boy who suffered from temporal lobe epilepsy and underwent a left temporal lobectomy with amygdalo-hippocampal resection at the age of 10. He showed an abnormal forgetting(More)
Ullman (2004) suggested that Specific Language Impairment (SLI) results from a general procedural learning deficit. In order to test this hypothesis, we investigated children with SLI via procedural learning tasks exploring the verbal, motor, and cognitive domains. Results showed that compared with a Control Group, the children with SLI (a) were unable to(More)
The study combined prospective neuropsychological and EEG results of 22 children presenting with typical benign partial epilepsy with rolandic spikes (n=19) and occipital spikes (n=3). The aims were to assess the types of cognitive problems which may be encountered in this population, to evaluate the course of cognitive and learning capacities during the(More)
The mastery of two languages provides bilingual speakers with cognitive benefits over monolinguals, particularly on cognitive flexibility and selective attention. However, extant research is limited to comparisons between monolinguals and bilinguals at a single point in time. This study investigated whether growth in bilingual proficiency, as shown by an(More)
Recent studies of handwriting have shown that linguistic variables, such as phonology or lexicality, influence various aspects of the production of letter sequences. Following a previous experiment, in which a facilitation effect of words over pseudowords has been documented both in children and in adults, an experiment is reported concerning the effect of(More)
A male presenting with benign partial epilepsy with rolandic spikes from the age of 7 years was evaluated at age 11 years for worsening of his epilepsy associated with a specific regression of graphomotor skills. A longitudinal study over nearly 2 years showed an improvement in handwriting to an almost normal level under modified antiepileptic therapy. A(More)
This paper reports the case of an English speaking, fully left-handed patient (DS) with a left unilateral writing deficit occurring after a subarachnoid hemorrhage due to the rupture of an anterior communicating aneurysm. DS's performance in spelling and in right-handed writing was entirely preserved while his left-handed writing was characterized by the(More)
We report a longitudinal study (7-11 years) of a previously normal boy (MR) who presented from the age of 5 years with rare partial motor seizures and atypical 'absences'. The history revealed a stagnation in development and speech difficulties a few months before onset of his epilepsy. The first waking electroencephalogram (EEG) showed rare generalized(More)
