Trial Outcomes & Findings for Strategies for Teaching Verbs (NCT NCT03441685)
NCT ID: NCT03441685
Last Updated: 2024-06-07
Results Overview
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.

PRIMARY outcome
Timeframe: From date of initial evaluation to focused intervention session, up to 1 monthPopulation: Analyzed eligible participants
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.

SECONDARY outcome
Timeframe: From date of initial evaluation to focused intervention session, up to 1 monthPopulation: Analyzed eligible participants
After the teaching episodes for the syntactic condition participants are asked to label novel verbs expressively. Participants were asked to label each of the 4 taught words per condition one time for a total of 4 trials per condition. This "expressive probe" has a minimum score of 0 and maximum of 4. Higher scores indicate a better outcome.
