Relatively late mastery of scalar implicatures has been suggested to correlate with children's immature processing capacities, such as their limited working memory. Yet, many studies that tested for a link between children's working memory and their computation of scalar implicatures have failed to find any correlation. One possible reason is that…

Pronoun reversal, the use of "you" for self-reference and "I" for an addressee, has often been associated with Autism Spectrum Disorder (ASD) and impaired language. However, recent case studies have shown the phenomenon also to occur in typically developing and even precocious talkers. This study examines longitudinal corpus data from two…

Suggests that Goad & Ingram's (1987) argument in favor of a cognitive model of phonological development failed to recognize the uniqueness of each individual's neural and vocal structures, ignored documented variability in the phonetic patterns of prelexical infants, and inexplicably assumed that inter-child variability implied the operation of…

This paper, based on naturalistic data, describes the acquisitional course and use of the articles "a" and "the" in young English-speaking children (18-61 months), with special emphasis on the role of individual variation. A growth modeling approach to the data reveals that children's individual acquisition schedules are similar in trend, but vary…

A study examined the consistency of consonant use in the infant's transition period from babbling to early words. Phonetic data were collected from the speech of 10 infants aged 9 to 15 months. Analysis of consonant distribution patterns indicate striking segmental preferences in all 10 children, with some segments more prominent for the sample as…

The diagnostic problem presented by children without obvious neurological, cognitive, genetic, emotional or environmental basis for their atypical or delayed language development is discussed. One unresolved issue is whether the deficits of such dysphasic children are linguistic or are more fundamental cognitive or perceptuomotor deficits. A…

Examines evidence offered to support the idea of a sensitive period for second language acquisition. Findings indicate that there is insufficient evidence to accept the claim that mastery of a second language is determined wholly, or even primarily, by maturational factors.

Focusing on the acquisition of semantic features and the relation between semantic and perceptual features, this study further tests the "semantic feature hypothesis," where a child acquires full adult word meaning component by component, and its complementary "correlation hypothesis," which claims that the source of these semantic features lies…
