In three experiments, a multiple habituation paradigm was used to examine the ability of 7- and 9-month-old prelinguistic infants to form a natural, basic-level object category. Findings constitute independent evidence for the existence of a linguistically relevant nonlinguistic category prior to the onset of word comprehension. (SED)

Presents a study of the early vocabulary of young children, considering variables such as contextual flexibility, content, and composition of the lexicon in comprehension and production. Reports evidence for a relative independence between these two domains, and for an early version of the referential style observed at later stages of development.…

Investigates young children's ability to adjust the content of their verbal responses according to what they know their listener knows. Younger and older three-year-old children were able to discern what another person knew and did not know and adjusted their responses accordingly.

Examines the role of prior intention and knowledge in the comprehension of "forget" by young children. Results reveal that children initially have two interpretations of "forget": an unfilled desire and a state of not knowing. Discusses explanations for the late comprehension of "forget" in terms of representation of knowledge and intention,…

Investigates the potential interaction of conceptual representations and linguistic systems during language acquisition. The study examined language-thought interactions in American, Finnish and Polish children, focusing on the conceptual and linguistic development of space and time. Findings reveal that spatial and temporal linguistic systems and…
