Children learn words by listening to caregivers, and the quantity and quality of early language input predict later language development. Recent research suggests that word recognition efficiency may influence the relationship between input and vocabulary growth. We asked whether language input and lexical processing at 28-39 months predicted…

This study investigated whether vocabulary delays in toddlers with autism spectrum disorders (ASD) can be explained by a cognitive style that prioritizes processing of detailed, local features of input over global contextual integration--as claimed by the weak central coherence (WCC) theory. Thirty toddlers with ASD and 30 younger,…

Children (ages 6-7 and ages 8-9) and adults participated in real-word and nonword lexical decision tasks and an auditory-vocal reaction time task. Response times on all tasks decreased with age. However, age-related differences on the real-word lexical decision task disappeared when differences in auditory-vocal reaction times were taken into…
