Infants are born highly sensitive to the natural patterns found in languages. They use their perceptual sensitivity to acquire detailed information about the structure of languages in their environment. To date, most studies of infant perception and early language acquisition have investigated spoken/auditory languages and hearing infants (e.g.…

Details BootLex, a model using distributional cues to build a lexicon and achieving significant segmentation results with English, Japanese, and Spanish; child- and adult-directed speech, and written text; and variations in coding structure. Compares BootLex with three groups of computational models of the infant segmentation process. Discusses…

Piaget's research on the processes and products of cognitive and representational development in early childhood is employed to outline the bases of early language development. The processes of assimilation and accommodation, leading to horizontal decalage; empirical and reflective abstraction, resulting in schemas and schemes; as well as…

Syntactic knowledge is widely held to be partially innate, rather than learned. In a classic example, it is sometimes argued that children know the proper use of anaphoric "one," although that knowledge could not have been learned from experience. Lidz et al. [Lidz, J., Waxman, S., & Freedman, J. (2003). What infants know about syntax but couldn't…

Studied were some cognitive aspects of the language development of a 2-year-old Puerto Rican boy who had been on the U.S. mainland 1 month. A Neo-Piagetian approach (developed by K. Witz and J. Easley) was used to study: language behavior as being embedded in more complex, unified systems; productivity of different structures and language…

This discussion centers on language development in young children particularly as it relates to Piaget's work. The author believes guidelines are lacking for describing structurally the outcome of the language acquisition process at different stages and that there should be more collaboration between linguists and psychologists in this area.

Five studies examined the contributions of syllable-ordering and rhythmic properties of syllable strings to 6- and 9-month-old infants' speech segmentation. Results indicate that the capacity for integrating multiple sources of information in speech perception emerges between 6 and 9 months, in rough synchrony with the emergence of integration in…
