PRIMARY outcome
Timeframe: immediately after viewing 3-minute interactionPopulation: Not all enrolled participants were analyzed because of exclusions due to, e.g., experimenter error or children paying insufficient attention.
Children's eye gaze is recorded as they look at images. The proportion of time during which gaze is directed to an image of the targeted word is the dependent measure.
