Input cues and verb comprehension with toddlers in a Looking-While-Listening Paradigm
by Kerns, Amanda Berry, M.S., UNIVERSITY OF SOUTH ALABAMA, 2009, 74 pages; 1465887

Abstract:

Twelve typically developing children (M age 24.4 months) participated in a Looking-While-Listening Paradigm that measured verb comprehension with the grammatical morpheme –ing, the ungrammatical morpheme –est, and the nonsense morpheme –il. Children, seated on a care giver's lap, viewed simultaneous split screen video events and heard the linguistic stimulus. Verb comprehension was determined based on time spent looking to a target event and the number of gaze shifts. Despite predictions, no significant differences were found and children's looking to target verbs (M = 59%) was no better than chance. A practice task consisting of nouns revealed significantly longer time spent looking to object pictures associated with target nouns ( M = 76%) compared to chance (p < .001) and the experimental verb task (p = .021). Three participants were excluded based on chance performance during the noun practice task. Data now revealed significantly longer looking times compared to chance for two morpheme conditions, –ing and –il, consistent with a predicted trend. This paradigm will support future research investigating linguistic and contextual factors associated with children's early sentence processing and word learning.
