By age 2, children are developing foundational language processing skills, such as quickly recognizing words and predicting words before they occur. How do these skills relate to children's structural knowledge of vocabulary? Multiple aspects of language processing were simultaneously measured in a sample of 2-to-5-year-olds (N = 215): While older…

To understand spoken words, listeners must appropriately interpret co-occurring talker characteristics and speech sound content. This ability was tested in 6- to 14-months-olds by measuring their looking to named food and body part images. In the "new talker" condition (n = 90), pictures were named by an unfamiliar voice; in the…

Lexical competition that occurs as speech unfolds is a hallmark of adult oral language comprehension crucial to rapid incremental speech processing. This study used pause detection to examine whether lexical competition operates similarly at 7-8 years and tested variables that influence "online" lexical activity in adults. Children…

Using a picture pointing task, this study examines toddlers' processing of phonological alternations that trigger sound changes in connected speech. Three experiments investigate whether 2;5- to 3-year-old children take into account assimilations--processes by which phonological features of one sound spread to adjacent sounds--for the purpose of…

Using online measures of familiar word recognition in the looking-while-listening procedure, this prospective longitudinal study revealed robust links between processing efficiency and vocabulary growth from 18 to 30 months in children classified as typically developing (n = 46) and as "late talkers" (n = 36) at 18 months. Those late talkers who…

Investigated three aspects of children's early language knowledge: (1) comparison of preschoolers response to written stimuli in familiar environmental contexts (on signs and billboards) with responses presented in a traditional reading task format; (2) developmental changes in preschoolers' knowledge of written language; and (3) preschoolers'…

Examined the associations among speech perception, phonological awareness, naming speed, verbal memory, and word reading. Multiple measures were administered to 136 3rd- and 4th-grade children. Results indicated that naming speed was particularly highly associated with speech perception, whereas phonological awareness was substantially correlated…

Two studies of toddlers and children with autism, mentally handicapped children, and normal toddlers examined whether autistic toddlers used Speaker's Direction of Gaze (SDG) strategy or less powerful Listener's Direction of Gaze (LDG) strategy to learn a word for a novel object. Results suggest autistic toddlers are insensitive to speaker's gaze…
