Study Summary
This study is designed to evaluate whether children with Down syndrome and children with typical development exhibit different levels of accuracy demonstrating novel verbs taught under three conditions: semantic cues (perform action), syntactic cues (sentence frame), and combined (syntactic and semantic cues). The participants complete an eligibility evaluation and then one verb learning session (approximately 60 minutes in length). During that verb learning session they are taught sets of words under each condition (i.e., within-subjects design) and then asked to identify and label those target words immediately after instruction.
Primary Outcome
Participants are asked to receptively identify novel verbs taught in syntactic condition by selecting the video of the named verb from a field of two. Participants were asked to identify each of the 4 taught words per condition 3 times for a total of 12 trials per condition. This "receptive probe" has a minimum score of 0 and maximum of 12. Higher scores indicate a better outcome.
