Emergence of vocal alternation in mother-infant interchanges
Authors: Ginsburg G. P. , Kilbourne Brock K. 
Published: February 2009

ABSTRACTMicroanalyses of unstructured videotaped interactions of three mother-infant dyads revealed dramatic shifts in dyadic vocalization patterns from primarily overlapping to primarily alternating. Maximal overlapping vocalization appeared between 7 and 13 weeks for the different dyads, and subsequent alternation predominance peaked between 12 and 18 weeks. The findings are compared with prior work which had not found alternation predominance and reasons for the difference are suggested. The early emergence of a sequence of predominantly overlapping vocalization followed by predominantly alternating vocalization may be linked to the concomitant development of multimodal sensory-sensory and sensory-motor integration. If so, then the emergent patterns reflect increased potential for co-ordination within the dyad, which may be capitalized upon by the mother and by the infant.
Role of adult input in young children's category evolution. I. An observational study
Authors: Mervis Carolyn B. , Mervis Cynthia A. 
Published: February 2009

ABSTRACTThree factors have been hypothesized to play an important role in the reduction of children's initial overextensions: spontaneous adult use of the correct label, correction of the child's errors, and demonstration of the important attributes that make an object a member of its adult category. The role of these factors was examined in relation to data collected from a longitudinal study of early lexical development. This study used an observational methodology combined with systematic comprehension and production testing. Results indicated that demonstrations were the most important factor in inducing toddlers to assign an object to its adult category. The question of why purely linguistic input initially plays a minor role in changing children's categories is discussed.
First steps in the acquisition of Spanish stress
Authors: Hochberg Judith G. 
Published: February 2009

ABSTRACTThis article uses longitudinal data from four Mexican-American children to explore two aspects of the acquisition of Spanish word stress that precede and accompany learning of the stress system itself. First, contrary to Allen & Hawkins' proposed universal ‘trochaic bias’ (Allen 1982, Allen & Hawkins 1977, 1979, 1980), it is shown that children have a ‘neutral start’ in stress learning: they approach the task of stress learning unbiased towards any particular stress type. Secondly, several examples are found in which children's attention to phonetic or semantic aspects of normatively unstressed syllables leads them to shift stress to that syllable.
On the logic of contrast
Authors: Clark Eve V. 
Published: February 2009

ABSTRACTThe Principle of Contrast, that different words have different meanings, holds for adult language use. But at what age do children assume Contrast ? Do they rely on it from the start, or do they assume that new words may have the same meaning (the Null Hypothesis) until they discover otherwise ? Both the Null Hypothesis and Contrast have certain consequences. The Null Hypothesis places a heavy burden on languagelearners, whereas children could discover Contrast as part of their experience of rational behaviour. Examples that have been claimed to go counter to Contrast fall into two groups. Those in the first do not in fact violate Contrast at all. Those in the second rely on sameness of extension instead of sameness of meaning, and so are indeterminate as counter evidence. Usage consistent with Contrast, on the other hand, is pervasive in children's speech from an early age.
From discourse to semantics: the development of verb morphology and forms of self-reference in the speech of a two-year-old
Authors: Gerhardt Julie 
Published: February 2009

ABSTRACTRecent linguistic studies have proposed that verb morphology has evolved to serve particular functions inherent to discourse. In this paper, an attempt is made to apply this proposal to the development of verb morphology in the spontaneous speech of a child from 1;10. 16 to 2;0.2. The question asked was whether there were any aspects of the child's discourse which may have been in part responsible for her differential use of verb morphology. To answer this question, a distributional analysis is presented of the child's speech in two different speech contexts: dialogue vs. crib-monologue. Despite the exiguous amount of data in the corpus, the analysis yields striking patterns of co-occurrences involving verb morphology and forms of self-reference. The patterns were interpreted as provisional evidence that the child may have been sensitive to discourse factors in her selective use of verb morphology. The data is analysed into four developmental phases. It is suggested that the semantic-level meanings of Phase IV are due in part to the type of discourse use to which the morphology is put in the earlier phases.
Patterns of parental vocabulary selection in speech to very young children
Authors: Ratner Nan Bernstein 
Published: February 2009

ABSTRACTPrevious studies have suggested that paternal vocabulary selection in speech to young children may be more diverse or demanding than that of mothers. This study examined the speech of eight mothers and eight fathers to their young language learning children. Nominal usage was subjected to TTR and frequency-of-occurrence analyses. In general, while paternal speech does not appear to be more diverse than maternal speech, it does appear to be characterized by greater usage of rare vocabulary and significantly lower usage of common vocabulary than is maternal speech.
Variation in human biology and child phonology: a response to Goad and Ingram
Authors: Locke John L. 
Published: February 2009

ABSTRACTGoad & Ingram (1987) use the mere existence of inter-child variability to argue in favour of a ‘cognitive’, and against a ‘biological’ model of phonological development (Locke 1983). In this response it is suggested that such an argument fails to recognize the uniqueness of each individual's neural and vocal structures, ignores documented variability in the phonetic patterns of prelexical (and arguably prephonological) infants, and assumes–inexplicably–that inter-child variability implies the operation of ‘cognitive’ factors.
Intonation with single words: purposive and grammatical use
Authors: Galligan Roslyn 
Published: February 2009

ABSTRACTThe study examined the transition to purposive use of intonation with single words for two children. Contrary to Bloom's (1973) claim of no systematic use of intonation in the one-word period, purposive use of rising tones was demonstrated in the context of indicating interest and naming objects. One child, by 1;3, clearly used rising tones to ask ‘legitimate’ questions in which the content of the replies mattered. If an informative response was not given he repeated his question accentuating the rising tone. The other child also sought informative replies, although this could only be established at 1;6. In addition, by 1;5 both children demonstrated widespread grammatical use of intonation in which a word was combined with distinct intonations to indicate a meaning distinction equivalent to one made by the grammar of the language. There were, however, earlier developments that presaged the way, so that the transition to grammatical use of intonation was gradual.
The eyes have it: lexical and syntactic comprehension in a new paradigm
Authors: Golinkoff Roberta Michnick , Hirsh-Pasek Kathryn , Cauley Kathleen M. , Gordon Laura 
Published: February 2009

ABSTRACTA new method to assess language comprehension in infants and young children is introduced in three experiments which test separately for the comprehension of nouns, verbs, and word order. This method requires a minimum of motor movement, no speech production, and relies on the differential visual fixation of two simultaneously presented video events accompanied by a single linguistic stimulus. The linguistic stimulus matches only one of the video events. In all three experiments patterns of visual fixation favour the screen which matches the linguistic stimulus. This new method may provide insight into the child's emerging linguistic capabilities and help resolve longstanding controversies concerning language production versus language comprehension.
Early words of blind children
Authors: Bigelow Ann 
Published: February 2009

ABSTRACTThe first 50 words of three blind children were collected and analysed using procedures used by Nelson (1973) on 18 sighted children. The early vocabulary of the blind children paralleled that of the sighted children in the age and speed of acquisition, and in the underlying characteristics of what the children chose to label. These reflect a sensorimotor organization in which self-action and perceptual change are the salient variables. The early words of the blind children differed from those of sighted children in the percentage of words in each of Nelson's grammatical categories. This suggests differences in how the children use language. These differences are discussed as a function of the children's lack of vision and their particular language learning context.
A Japanese child's use of stative and punctual verbs
Authors: Cziko Gary A. , Koda Keiko 
Published: February 2009

ABSTRACTThis study investigated the use of stative, process, punctual, and non-punctual verbs by a child acquiring Japanese as a first language between the ages of 1;0 and 4;11 in an attempt to find evidence for two of Bickerton's (1981) proposed language acquisition universals, which form part of the language bioprogram hypothesis of language acquisition. As predicted by Bickerton's state-process hypothesis, it was found that all sampled present progressive verb forms occurred with process verbs while these forms were never used with stative verbs. Also, with only one exception, all omissions of present progressive forms occurred with the early use of ‘mixed’ verbs, i.e. verbs which behave syntactically as process verbs in Japanese but are nonetheless semantically stative. However, contrasting with Bickerton's hypothesis that children initially use the past tense to mark punctuality, no relationship between past tense use and punctuality was found.
Type/Token Ratios: what do they really tell us?
Authors: Richards Brian 
Published: February 2009

ABSTRACTType/Token Ratios have been extensively used in child language research as an index of lexical diversity. This paper shows that the measure has frequently failed to discriminate between children at widely different stages of language development, and that the ratio may in fact fall as children get older. It is suggested here that such effects are caused by a negative, though non-linear, relationship between sample size (i.e. number of tokens) and Type/Token Ratio. Effects of open and closed class items are considered and an alternative Verbal Diversity measure is examined. Standardization of the number of tokens before computing Type/Token Ratios is recommended.
Parents' speech to toddlers: the effect of play context
Authors: O'Brien Marion , Nagle Keith J. 
Published: February 2009

ABSTRACTThe language of mothers and fathers to their toddler sons and daughters at play with three different types of toy was analysed for both sentence types and structural elements. Two of the play contexts, dolls and vehicles, were highly sex-role stereotyped, and the third, shape sorters, was neutral. Few differences in speech were found as a function of either parent or child gender. Each of the three play contexts, however, elicited its own language pattern. With dolls, parental speech was characterized by a relatively large amount of language and a frequent use of questions and nouns, especially by contrast with vehicle play, which involved little language. Play with shape sorters elicited a high proportion of directives and attentionals and a relatively low variety in language. These results suggest that children who play frequently with dolls may receive more opportunities to learn and practise language than do children who select other toys for play. In this way early toy preferences may contribute to differential socialization by parents.
Subject and agent in emerging grammars: evidence for a change in children's biases
Authors: Matthei Edward H. 
Published: February 2009

ABSTRACTThis paper presents the results of two experiments which appear to show that children's linguistic generalizational biases change from a semantically based system to a syntactic-structural system. The experiments use the constituent repetition paradigm of Read & Schreiber (1982). Subjects were trained to repeat the subject noun phrase in orally presented sentences. Preschoolers, but not second-graders, displayed a tendency to repeat the agentive noun phrase (contained in the by-phrase) in semantically irreversible passive sentences. It is argued that the results provide more evidence for a semantic-relational bias in children's early grammars, and that the results also provide support for the notion that children's generalizational biases shift from a semantic relational basis to a syntactic-structural basis some time between the preschool and early grammar school years.
The range of narrative forms conversationally produced by young children
Authors: Preece Alison 
Published: February 2009

ABSTRACTThe productive narrative competence of three young children as revealed in their spontaneously occurring conversations recorded over an 18-month period during their kindergarten and grade one years was investigated. Almost 90 hours of the children's conversations, produced as they were being driven to and from school, were audiotaped and analysed in order to determine whether children between the ages of five and seven include narrative accounts in their conversations with each other and, if so, the nature of the narrative language produced. The subjects were found routinely and regularly to produce a striking variety of narrative forms; 14 different narrative types were distinguished and defined, six of which have not previously been reported in the literature on children's narratives. Seventy per cent of the recorded narratives took anecdotal form; original fantasy narratives occurred only rarely. A significant proportion of the narratives were collaboratively created.
The connective ‘and’: do older children use it less as they learn other connectives?
Authors: Peterson Carole , McCabe Allyssa 
Published: February 2009

ABSTRACTThe connective and has frequently been described as a useful allpurpose connective that is used as a vehicle for introducing new inter-sentential semantic relationships. As new and more specific connectives are acquired, they are matched to these meanings. An assumption is that as children get older, and should be used less to express the various meanings for which more specific connectives exist; rather, it should be increasingly reserved for simple co-ordination. This hypothesis was tested by examining narratives produced by children between 4 and 9 years old; contrary to expectation, and was used no differently by 9-year-olds than by 4-year-olds, and simple co-ordination constituted no more than 20% of the relationships. The role of and may be to indicate cohesion between sentences, without regard to semantic relationship.
Locative terms and Warlpiri acquisition
Authors: Bavin Edith L. 
Published: February 2009

ABSTRACTCognitive complexity and complexity of linguistic structure have been found to influence the order of acquisition of locatives. In Warlpiri, locative terms are nominals and they are used in combination with a locative case marker on the reference object; directional affixes may be added to them. Data from a series of tests of Warlpiri children's comprehension and production of the Warlpiri expressions that may be translated as ‘in’, ‘on’, ‘under’, ‘in front of’, ‘behind’ and ‘between’ indicate that the locative case forms are used first without the more specific locative nominals; young children distinguish an ‘up-down’ dimension but not ‘in’, and the reference object influences how the locative term is interpreted; kamparru-pirdangirli (‘front-behind’) is not one dimension for children aged four to five years; kulkurru ‘between’ is understood before kamparru ‘front’ and pirdangirli ‘behind’; the use of features on a reference object for orientation develops at around six, but the orientation of the reference object, as well as features on the placed object may affect interpretation.
Maternal speech and the child's development of syntax: a further look
Authors: Hoff-Ginsberg Erika 
Published: February 2009

ABSTRACTThe present study compared four categories of maternal utterances that were found in a previous study (Hoff-Ginsberg, 1986) to predict children's rates of syntax development to a category of maternal utterances that was unrelated to syntax development. The comparisons were designed to test the hypotheses that maternal utterances which benefit syntax development do so by providing syntactically rich data or by eliciting conversation from the child. Data-providing and conversation-eliciting characteristics of the selected categories of maternal utterances were assessed from the same transcripts of 22 mothers interacting with their 2½-year-old children that had provided the database for the earlier study of predictive relations. Each of the three positive predictor categories of maternal utterances differed from the unrelated category — in more frequently illustrating the affected aspect of syntax development, in eliciting more speech from the child, or both. Neither of these characteristics was true of the negative predictor category. The pattern of results suggested that maternal speech supports the child's development of syntax by engaging the child in linguistic interaction and also by providing illustrations of the structures the child acquires.
Second-language acquisition via immersion in daycare
Authors: Karniol Rachel 
Published: February 2009

ABSTRACTThis paper presents a case study of second-language acquisition of Hebrew via immersion in daycare between 1;10 and 3;0. A period of silence was followed by rapid onset of L2 production simultaneously with many references to language itself. Eight types of language awareness were identified, and of these, several types may be prerequisites for starting L2 production. The nature of L2 speech during the first stages of production suggests that to crack the sematic code of L2, the child relies on identifiable contingencies between utterances and subsequent behaviours by speakers and listeners. As a result there are many more imperatives and interrogatives in L2 than are evident in L1 speech, and these appear to be learned by rote in an unanalysed manner. The transition to complex constructions occurs via the juxtaposition of known but syntactically unanalysed chunks, and results in patterns of syntactic errors similar to those of adult second-language learners. Reliance on L1 as a fall-back strategy was also evident. Several implications of these data for cognitive development in general are discussed.
Early lexical acquisition: rate, content, and the vocabulary spurt
Authors: Goldfield Beverly A. , Reznick J. Steven 
Published: February 2009

ABSTRACTThe transition from slow to rapid word-learning was examined in a longitudinal study of 18 children. Beginning at age 1;2, mothers kept a diary of children's words. Diary entries were discussed during phone calls to the home every 2½ weeks. A chronological record of nouns and other word classes was coded from the diary records.Thirteen children evidenced a prolonged period of up to three months during which rate of acquisition markedly increased. Almost threequarters of the words learned during this period were nouns. Five children evidenced more gradual word-learning, and acquired a balance of nouns and other word classes. These results suggest that the terms ‘vocabulary spurt’ and ‘naming explosion’ best describe children who focus their early linguistic efforts on a single strategy: learning names for things. Other children may attempt to encode a broad range of experience with a more varied lexicon, a strategy that results in more gradual lexical growth.
Similarity neighbourhoods of words in young children's lexicons
Authors: Charles-Luce Jan , Luce Paul A. 
Published: February 2009

ABSTRACTSimilarity neighbourhoods for words in young children's lexicons were investigated using three computerized databases. These databases were representative of three groups of native English speakers: 5-year-olds, 7-year-olds, and adults. Computations relating to the similarity neighbourhoods of words in the children's and adult's lexicon revealed that words in the 5- and 7-year-olds' lexicons have many fewer similar neighbours than the same words analyzed in the adult lexicon. Thus, young children may employ more global recognition strategies because words are more discriminable in memory. The neighbourhood analyses provide a number of insights into the processes of auditory word recognition in children and the possible structural organization of words in the young child's mental lexicon.
Children's understanding of adverbs denoting degree of likelihood
Authors: Hoffner Cynthia , Cantor Joanne , Badzinski Diane M. 
Published: February 2009

ABSTRACTTwo studies were conducted to examine children's understanding of three terms that denote different degrees of likelihood: possibly, probably and definitely. In Study 1, children in preschool, and first, third and fourth grade completed a comparison task involving pairs of likelihood terms. Twelve stories were created that described the likelihood that each of two children would participate in an activity, and subjects judged which of the two children actually participated. In Study 2, children in preschool, and first, third and fifth grade evaluated separate statements describing three different children, each of whom was said to have a different estimate of the likelihood that a scary event depicted in a movie would actually occur. Subjects rated how scared each of the three children felt. The results of the two studies revealed that preschoolers showed very little comprehension of the meaning of any of the three words, but by fourth grade the majority of children distinguished among all three terms. Children understood the distinction between definitely and both of the other terms (possibly, probably) better than they understood the distinction between possibly and probably. This finding is consistent with research on the development of children's understanding of probability concepts. Unexpectedly, the distinction between probably and definitely seems to emerge at a younger age than the distinction between possibly and definitely. The findings are discussed in terms of their implications for communicating verbal messages to children.
