Title: The effect of visual arrangement on visuospatial short-term memory: Insights from children with 22q11.2 deletion syndrome.
Authors: Attout, Lucie, Noël, Marie-Pascale, Rousselle, Laurence

Subjects: Short-term memory in children, Unilateral neglect, Nonverbal learning disabilities, Williams syndrome, Down syndrome
Abstract: Recent models of visuospatial (VSSP) short-term memory postulate the existence of two dissociable mechanisms depending on whether VSSP information is presented simultaneously or sequentially. However, they do not specify to what extent VSSP short-term memory is under the influence of general VSSP processing. This issue was examined in people with 22q11.2 deletion syndrome, a genetic condition involving a VSSP deficit. The configuration of VSSP information was manipulated (structured vs. unstructured) to explore the impact of arrangement on VSSP short-term memory. Two presentation modes were used to see whether the VSSP arrangement has the same impact on simultaneous and sequential short-term memory. Compared to children matched on chronological age, children with 22q11.2 deletion syndrome showed impaired performance only for structured arrangement, regardless of the presentation mode, suggesting an influence of VSSP processing on VSSP short-term memory abilities. A revised cognitive architecture for a model of VSSP short-term memory is proposed. [ABSTRACT FROM AUTHOR]
