Two experiments showed that: 5- and 6-year-old listeners have difficulties with spatial reference if it includes "left" and "right"; and 7-year-olds understand this limitation on the comprehension skill of younger children and make appropriate allowances by using more landmarks instead. (CB)

When asked to judge as correct or incorrect three categories of sentences (those with errors similar to their own patterns, those with common "baby errors," and correct sentences), four-year-olds made significantly fewer corrections of errors similar to their own, suggesting that children learn their own errors. (MSE)

Discusses the establishment of a morpheme-per-utterance (MPU) index as opposed to the standard mean-length of utterance (MLU) for measuring the linguistic proficiency of two- to three-year-old Hebrew speakers. (EKN)

Presents a longitudinal study of six children which investigates the relationship between language development and the development of nonverbal representation. Concludes that the results suggest an interrelational hypothesis and proposes an interpretation in terms of reciprocal interaction between the two parameters. (Author/MES)

Command of transitivity permutations in Hebrew, where a change in verb-argument syntax entails a change in verb morphology, were examined in 30 children aged 2, 3, and 8. Findings have implications for the development of derivational morphology, item-based versus class-based learning, and the impact of lexical productivity and language-particular…

A blind child and her sighted twin sister were recorded at home once a month from 2;5 to 3;5, and their repetitions and routines were analyzed with respect to three dimensions. Results showed that the blind twin used routines and modified imitations and repetitions more frequently, and her use of modified repetitions increased during the study.…

Data from 34 children suggest that a range of Italian grammatical morphemes reach the level of mastery by age 3;6-4;0. In the period between 2;6 and 3;0, as use and comprehension of morphemes are being consolidated, homonymy and informativeness seem not to play a role, though number continues to exert an influence. Some form classes of Italian are…

The lexical variables of word frequency and neighborhood density were hypothesized to facilitate sound change to varying degrees. Twelve children with functional phonological delays participated in an alternating-treatments experiment to promote sound change. Results indicated word frequency was most facilitative in sound change, whereas dense…

Recent studies have suggested that cultures vary in subtle ways in the talk about talk that children hear and learn to produce. Twenty-two three-year-old children and their families in respectively Oslo, Norway and Cambridge, Massachusetts were observed during mealtime with the aim of identifying talk-focused talk. The analysis distinguished talk…

Evaluates the principle of laryngeal-supralaryngeal cyclicity by manipulating the domain cycle and phase relationship of the cycle as independent variables and by monitoring longitudinally the order of emergent phonemic distinctions in the sound systems of seven children with phonological delays as the dependent variable. Findings are discussed.…

Tests Pine & Lieven's (1993) suggestion that a lexically-based positional analysis can account for the structure of a considerable proportion of children's early multiword corpora. Results reveal that the positional analysis accounts for 60% of the children's multiword utterances and that most other utterances are defined as frozen. (33…

Naturalistic mother-child speech between autistic, Down's syndrome, or normal children and their mothers was studied to determine whether imitation facilitates grammar acquisition. Spontaneous utterances were longer and contained more advanced grammar than imitation utterances, indicating that imitation does not play a significant role in grammar…

Longitudinal observation of one- to three-year-olds' (N=2) acquisition of complement phrasal construction in Korean found that, in spite of typological differences between English and Korean, both syntactic and semantic characteristics were shared by children acquiring complement structure in the two languages. (Author/CB)

Describes a preschool child's gradual acquisition of a play language, Pig Latin, and discusses the abilities and errors that were measured over the course of acquisition. Acquisition improved as the subject developed language abilities involving word identification, first-consonant deletion, suffix creation, and short-term memory for speech units.…

Investigated simple, appearance-predicted, and reality-predicted labelling in 36 3-, 4-, and 5-year olds. An age-related appearance-reality shift was observed in simple labelling. It is argued that younger children maintained the one-label-per-predicate pattern because of inflexible encoding; older children did so because of better understanding…
