Many researchers have recently explored the cognitive profile of velocardiofacial syndrome (VCFS), a neurodevelopmental disorder linked to a 22q11.2 deletion. However, verbal short-term memory has not yet been systematically investigated. We explored verbal short-term memory abilities in a group of 11 children and adults presenting with VCFS and two control groups, matched on either CA or vocabulary knowledge, by distinguishing short-term memory for serial order and item information. The VCFS group showed impaired performance on the serial order short-term memory tasks compared to both control groups. Relative to the vocabulary-matched control group, item short-term memory was preserved. The implication of serial order short-term memory deficits on other aspects of cognitive development in VCFS (e.g., language development, numerical cognition) is discussed. [less ▲]

Mean length of utterance (MLU) of children with Down syndrome was examined and found to correlate highly with chronological age, r = .87, p less than .001, despite the children's language delays. The ... [more ▼]

Mean length of utterance (MLU) of children with Down syndrome was examined and found to correlate highly with chronological age, r = .87, p less than .001, despite the children's language delays. The correlation was reliable at least up to MLU 3.00. In the 1.00 to 3.50 range, MLU also predicted grammatical complexity. [less ▲]
