Parent–child interaction is critical for early language and literacy development. Parent training programs have proliferated to support early interactions. However, many environmental and psychosocial factors can impact the quality of parent–child language and literacy interactions as well as training program outcomes. This preliminary randomized controlled trial examined maternal perceived self-efficacy and locus of control during a language and literacy parent training program. Thirty mother–child dyads (mother age 21–40; children 2;6–4;0) were assigned in parallel to the training or control group. The training was efficacious for mothers and children – training-group dyads made significantly greater gains in maternal strategy use, responsivity, and child print awareness than the control group. Gains were maintained one month post-training. Children whose mothers had more external baseline control perceptions identified significantly fewer print targets at baseline and made greater gains than those with more internal control perceptions. Future directions and implications are discussed.

We trained forty German-speaking children aged 1;8–2;0 in their comprehension of UNTER [UNDER]. The target word was presented within semantically organized input in the form of a ‘narrative’ to the experimental group and within ‘unconnected speech’ to the control group. We tested children's learning by asking them to perform an UNDER-relation before, immediately after, and again one day after the training using familiarized and unfamiliarized materials. Compared to controls, the experimental group learned better and retained more. Children with advanced expressive lexicons in particular were aided in generalizing to unfamiliarized materials by the narrative presentation. This study extends our understanding of how narrations scaffold young children's enrichment of nascent word knowledge.

Sixteen children (17 age mates, 17 vocabulary mates) with specific language impairment (SLI) participated in two studies. In the first, they named fantasy objects. All groups coined novel noun–noun compounds on a majority of trials but only the SLI group had difficulty ordering the nouns as dictated by semantic context. In the second study, the children described the meaning of conventional noun–noun compounds. The SLI and AM groups did not differ in parsing the nouns, but the SLI group was poorer at explaining the semantic relationships between them. Compared to vocabulary mates, a larger proportion of the SLI group successfully parsed the compounds but a smaller proportion could explain them. These difficulties may reflect problems in the development of links within the semantic lexicon.

An unusual phonological pattern exhibited by a child aged 2;9 is described. The pattern involved the production of word-final strident continuants in words whose adult forms contain these features in initial, rather than final position (e.g. [ops] for soap). The data are interpreted as compatible with models of child phonology that permit direct mapping of features to final position.

Forty children, aged 1 ; 8–2 ; 0, participated in one of three training conditions meant to enhance their comprehension of the spatial term under: the +Gesture group viewed a symbolic gesture for under during training; those in the +Photo group viewed a still photograph of objects in the under relationship; those in the Model Only group did not receive supplemental symbolic support. Children's knowledge of under was measured before, immediately after, and two to three days after training. A gesture advantage was revealed when the gains exhibited by the groups on untrained materials (but not trained materials) were compared at delayed post-test (but not immediate post-test). Gestured input promoted more robust knowledge of the meaning of under, knowledge that was less tied to contextual familiarity and more prone to consolidation. Gestured input likely reduced cognitive load while emphasizing both the location and the movement relevant to the meaning of under.

To examine interactions between young children's vocabulary size and their phonological abilities, spontaneous language samples were collected from 24-month-olds with precocious lexicons, their age mates (24-month-olds with average-sized lexicons), and their vocabulary mates (30-month-olds with average-sized lexicons). Phonological ability was measured in a variety of ways, such as the number of different consonants that were targeted, the number of different consonants produced correctly, the percentage of consonants produced correctly, and the occurrence of phonological processes. The lexically precocious 24-month-olds were similar to their vocabulary mates on most measures of phonological ability, and both of these groups were generally superior to the 24-month-olds with smaller lexicons. These findings supported a hypothesized relationship between lexicon size and phonological performance, and demonstrated that 2-year-olds' phonological development is more closely related to size of the lexicon than chronological age.

This is a study of the lexical and grammatical abilities of 16 lexically precocious talkers. These children, aged 2;0 were compared to their age-matched peers, 22 typical talkers aged 2;0, and their expressive vocabulary-matched peers, 22 typical talkers aged 2;6. Individual differences in children's lexical knowledge at 2;0 were stable – evident in parent report, laboratory observation, and an experimental fast-mapping paradigm. In accordance with the continuity hypothesis, the lexically precocious children were also grammatically precocious, having a greater representation of grammatical types and tokens and more advanced combinatorial language than their typical age-matches. Their grammatical development was very similar to that of their older vocabulary-matched peers. Limits on continuity were highly constrained with no true dissociation between the lexicon and the grammar in 33 cases examined. We conclude that, among two-year-olds, grammatical development is more tightly associated with the size of the lexicon than with chronological age.

A set of tri-zygotic quadruplets, three girls and one boy, participated in weekly observations from 1;2 to 1;10 (years;months), a period of transition from prelinguistic gesture to 50 words. In the study, one girl served as a genetic mate to her identical twin and a biological risk mate to her fraternal sister. The biological risk mates achieved milestones in lexical development at similar times; however, the genetic mates demonstrated more similarities in pattern of lexical development and in the modality of their word productions. Degree of similarity changed over the observation period. Imposed upon the natural experiment was a within-subject manipulation of the social environment: The experimenters modelled a core vocabulary via the gesture+verbal modalities to the children during each visit. The modelling resulted in increased rates of word learning for three of the children; the child with the greatest biological risk, the boy, derived the greatest benefit. The findings provide unique support for a dynamic, multi-factorial model of lexical development involving the interaction of genetics, the biological environment and the social environment. Furthermore, they illustrate the robustness of early lexical development in the face of biological risks.

The present study examined the composition of the early productive vocabulary of eight Korean- and eight English-learning children and the morpho-syntactic, semantic, and pragmatic characteristics of their caregivers' input in order to determine parallels between caregiver input and early lexical development. Vocabulary acquisition was followed using maternal diary and checklists for the Korean-learning children (from a mean age of 1;6 to 1;9) and for the English-learning children (from a mean age of 1;4 to 1;8). Results showed that both Korean- learning and English-learning children acquired significantly more nouns than verbs at the 50-word mark. However, Korean children learned significantly more verbs than did English-learning children. The relative ease with which Korean learners, as compared to English learners, acquired verbs parallels several differences in the linguistic and socio-pragmatic characteristics of the input addressed to them. Korean- speaking caregivers presented more activity-oriented utterances, more verbs, and more salient cues to verbs than did English-speaking caregivers. These data suggest that both general and language-specific factors shape the early lexicon.

According to the storage hypothesis (Kail & Leonard, 1986), word-finding deficits in young children are not the direct result of deficient retrieval strategies; they are a manifestation of a general delay in language development that affects lexical storage. In the current study, we explored one aspect of lexical storage, the hierarchical organization of the semantic system, in 13 preschoolers with word-finding deficits (WF) and 13 preschoolers with normal language abilities (ND), ranging in age from 3;3 to 6;7. The children named a series of objects at multiple levels of the noun hierarchy in response to contrast questions (e.g. for rose they were asked, ‘Is this an animal?’ to elicit plant [superordinate]; ‘Is this a tree?’ to elicit flower [basic]; ‘Is this a dandelion?’ to elicit rose [subordinate]). Both groups readily named at multiple levels, providing evidence of hierarchical organization of the lexicon. However, there were several differences between WF and ND groups that suggested that WF children did not have enough stored information to discriminate between similar semantic neighbours. We conclude (1) that hierarchical organization of the semantic lexicon is a robust developmental phenomenon, apparent in both ND and WF preschoolers and (2) that the word-finding deficits of preschoolers appear to reflect insufficient depth and breadth of storage elaboration rather than deficits in hierarchical semantic organization.
