Investigated whether children age 2; age 0-2; and 2 years used grammatical and caregiver cues in sentence comprehension and how different types of cues interacted. Children listened to sentences and identified pictures. Results indicated that children used caregiver cues (e.g., short length and position of key words) in sentence comprehension. Both language-internal and caregiver cues appeared to be important in early sentence comprehension. (SM)
