ABSTRACT

Using an adaptation of Grober and Buschke's procedure, we assessed verbal and visuospatial learning abilities in 16 children after left or right anteromesial temporal resection and 16 healthy controls to evaluate material-specific memory deficits. All children had relatively well-preserved verbal and spatial learning capacities after unilateral temporal resection. Children who had left temporal resection showed impaired verbal memory performance despite semantic control by cued recall. No memory deficits with visual material were detected in children who underwent right anteromesial temporal resection. Grober and Buschke's procedure appears relevant for the detection of verbal memory disorders in children with left-sided temporal resection.

ABSTRACT

The first aim of the study was to compare developmental trends in the degree of laterality (independent of direction) observed in two handedness tasks. The second aim was to assess family resemblance in the degree of laterality using the same two tasks. The sample was comprised of 186 left-handers and 302 right-handers aged from 6 to 66. Some of the sample were members of the same families. Bishop's card-reaching task was used to assess hand preference, and Annett's peg-moving task to assess manual performance. For the card-reaching task, children aged 7 to 10/11 recorded more midline crossings than the other age groups (both younger and older). No general age-related trend was observed for the Annett pegboard. For the card-reaching task, family resemblance was very low and not significant. The degree of laterality, assessed with the peg-moving task, showed a small but significant resemblance in father-offspring pairs (sons and daughters). Putative involvement of a maternally suppressed gene on chromosome 2p12 and of the androgen receptor was discussed.
