Abstract

The purpose of this study was to determine whether memory support and elicited production differentially benefited fast mapping of new vocabulary (comprehension, production accuracy, and speed) in adolescents with Down syndrome (DS) compared with typically developing (TD) children matched for syntax comprehension. The study also examined predictors of individual difference within groups. The ability of 19 adolescents with DS to fast map new noun vocabulary was compared with 18 TD children matched for syntax comprehension. The effects of memory support (5 examiner repetitions of the novel word vs. 1) and elicited production (2 repetitions by child vs. none) were evaluated in a repeated-measures design with counterbalancing of tasks. For novel word comprehension, low memory support impaired the TD but not DS participants. DS participants were slower to respond correctly in all conditions but benefited more from memory support than TD participants in speed of response. For novel word production, high memory support benefited all participants in the no-elicited-production condition. Elicited production improved performance equally in the 2 memory conditions. Standard comprehension measures predicted fast-mapped comprehension: vocab...Continue Reading
