Carol Stoel-Gammon has made a real contribution in bringing together two fields that are not generally jointly addressed. Like Stoel-Gammon, we have long focused on individual differences in phonological development (e.g. Vihman, Ferguson & Elbert, 1986; Vihman, Boysson-Bardies, Durand & Sundberg, 1994; Keren-Portnoy, Majorano & Vihman, 2008). And…

Results of a statistical study of language in 30 infants suggest that two acquisition styles (nominal/pronominal and referential/expressive) are developing in parallel. Only for children heavily emphasizing one strategy can a distinctive style be determined. Results at 20 months were only partially predictive of performance at 28 months. (MSE)

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…

Describes two types of feedback (explicit and implicit) in the responses of four mothers to their two-year-old children and investigates whether these mothers respond differentiallly to their children's well-formed and ill-formed utterances with either type of feedback. Results demonstrate that a high proportion of maternal responses qualify as…

The role of cognitive and linguistic individual differences as well as contextual factors and processing complexity were examined as determinants of pronoun reversal (I/you). It is proposed that pronoun reversals commonly result from a failure to perform a deicitic shift, which is especially likely when children's psycholinguistic processing…

The current study attempts to differentiate effects of phonotactic probability (i.e. the likelihood of occurrence of a sound sequence), neighbourhood density (i.e. the number of phonologically similar words), word frequency, and word length on expressive vocabulary development by young children. Naturalistic conversational samples for three…

Six children were visited in their homes every 2 weeks for 18 months from the age of 6 months to observe their developing comprehension and production of words. Results showed both similarities and individual differences in patterns of early comprehension. A close relationship was noted between early production and comprehension of words;…

The phonemic inventories of 30 children (aged 3;4-5;7) with phonological delays were examined in terms of featural distinctions to address universal vs. individual accounts of acquisition. Phonetic inventories of the same children were also identified for comparison purposes. (Contains 40 references.) (JL)

Describes a study done to determine whether the degree of children's familiarity with component words was related to (1) their ability to produce productive patterns as opposed to associative and grouping patterns, and (2) their ability to use broader scope rather than lexically based patterns. (SED)

Describes the presence of a phonological selection strategy and consonant harmony rule in one child's developing phonological system. Evidence suggests that this constant harmony constraint operated across morpheme boundaries, causing a delay in the onset of two-word utterances and influencing the selection of words that could occur in word…

Videotapes of 45 subjects at 1;1 and 1;8 showed preexisting differences between mothers of earlier and later talkers as early as 1 year, 1 month. When the sample was divided according to stylistic preference at 1;8 (referential or expressive), associations between maternal language at 1;1 and mean length of utterance at 1;8 emerged only for the…
