The mosaic acquisition of grammatical relations
Authors: Rispoli Matthew 
Published: February 2009

ABSTRACTThe view that grammatical relations have substantial essence, designated as ‘subject’ or ‘object’ has difficulty in accounting for the variety of naturally acquirable grammatical relations. The acquisition of grammatical relations is examined from a theoretical framework, ROLE AND REFERENCE GRAMMAR, in which grammatical relations are decomposed into two separate types of structure: logical (semantic) structure and information (pragmatic) structure. The acquisition of grammatical relations from four languages is compared: (1) the definite accusative suffix and pragmatically motivated word order of Turkish; (2) Kaluli verb agreement, case and focus marking postpositions, and pragmatically motivated word order; (3) Hungarian definite and indefinite verb conjunction; and (4) Italian participial agreement and anaphoric, accusative case pronouns. Two conditions on structures are found to cause difficulty: the neutralization of a semantic or pragmatic distinction by interfering structures (e.g. Kaluli and Italian), and global case marking which forces the child to discover relevant semantic characteristics of both the actor and the undergoer (e.g. Hungarian and Kaluli). Structures that encode semantic or pragmatic distinctions independently are more easily acquired (e.g. Turkish). Piecing together discrete structures in a mosaic fashion, the child can acquire the great variety of grammatical relations that exist in human languages.
Mean length of utterance and the acquisition of Irish
Authors: Hickey Tina 
Published: February 2009

ABSTRACTOne of the most widely used indices of language development is a measure of utterance length in morphemes (MLUm). This study examines the applicability of MLUm to the acquisition of Irish. MLUm was calculated for data from Cian, aged 1;11–3;0. Even when an attempt was made to ‘assume the maximum’ by counting all possible morphemes, the correlation between a morpheme MLU (MLUm) and a word count MLU (MLUw) was very high (0·99). This points to MLUw being as effective a measure of Irish development as MLUm, as well as being easier to apply and more reliable. MLUw was calculated for the two younger children in the study (Eibhlís 1;4–2;1 and Eoin 1;10–2;6). An examination of the relationship between the three children's MLUw values and their grammatical complexity as measured on ILARSP (the Irish adaptation of LARSP) indicates that MLUw is a useful preliminary index for early development in Irish. However, further data are necessary to check whether MLUw loses its predictive relationship with grammatical complexity after a certain point. The study emphasizes the caution necessary in applying MLU to languages whose acquisition has not hitherto been studied, and underlines the role of MLU as a preliminary measure, which must not be overinterpreted.
‘Can I put – I want a slippers to put on’: young children's development of request forms in a code-switching environment
Authors: Youssef Valerie 
Published: February 2009

ABSTRACTThis paper concerns the development of semi-modal want/want to, and modals may, can and could in two Trinidadian children, whose Verb Phrase development was studied in naturalistic settings, between the ages of 2;3 and 4;1, and 2;4 and 4;9. The similarities and differences in development between the two are important for underlining a number of key factors in the acquisition process. Accepting the salience of requests/demands in early child language, the study draws attention to the child's propensity for using the means most readily available to him/her in the input, for expression of this function. Additionally, there is evidence of the child's ability to make stylistic discriminations at a very early age and of the propensity for making semantic distinctions among forms. The study indicates that work on the development of grammatical features is incomplete without consideration of sociolinguistic aspects of usage as integral to grammatical acquisition from the outset.
Simultaneity in children's narratives: the case of when, while and as
Authors: Silva Marilyn N. 
Published: February 2009

ABSTRACTThis study examines the use of the co-temporal connectives when, while and as in the elicited narratives of 71 children between 4;10 and 11;11. A group of 26 adults provided comparison data. Subjects were asked to ‘tell a story’ about each of three sets of story pictures. Analysis of the adult data confirmed a preference for preposed over postposed when clauses and supported the notion of a continuum of simultaneity for when, while and as. The oldest children (like the adults) were more likely to prepose when clauses than were younger children, a finding which suggests that with increasing awareness of the information needs of the listener, children begin to use preposed adverbial clauses as information ‘guideposts’. Surprisingly, however, children in general were far more likely than adults to use durative predicates with when clauses and did not use co-temporal as – substituting when or while in those contexts in which as appeared in the adult protocols. These two findings are shown to be connected, since aspect in the adult data is differentially distributed with respect to the three connectives. It is hypothesized that for narrative purposes children acquire when before while and while before as, in the order of increasing specificity and constraint, with the determining factor being a convergence of syntax, semantics and information flow.
Pitch characteristics of Japanese maternal speech to infants
Authors: Masataka Nobuo 
Published: February 2009

ABSTRACTThe fundamental frequency F0 patterns of maternal speech addressed to infants aged 0;3–0;4 were measured quantitatively. Speech samples were recorded when six Japanese-speaking mothers addressed an adult and their own infants. Japanese mothers speaking to adults use a relatively restricted F0 range, concentrated around the mother's F0, which tends to be near the low end of the total range used. These acoustic characteristics are not altered substantially when these same women speak to their infants in initial utterances to attract the infants' attention. If such attempts are unsuccessful, however, they are likely to make more exaggerated utterances, in which F0 shifts upward and the frequency range is significantly increased. Moreover, only when acoustic characteristics of maternal speech to infants are exaggerated, can the type of F0 contour of the infant's subsequent response be predicted to a significant extent from the mother's preceding utterance.
Epistemic modality in French children's discourse:to be sureornot to be sure?
Authors: Bassano Dominique , Hickmann Maya , Champaud Christian 
Published: February 2009

ABSTRACTThis study focuses on the development of epistemic modality, with particular attention to how French children evaluate the conditions of use for modal expressions marking certainty and uncertainty. Sixty children aged four, six and eight were shown films involving verbal interactions in which a target speaker accused another of having performed a deed. The analysis examine children's responses during a subsequent interview in which they were asked to attribute an epistemic attitude of certainty/uncertainty to the target speaker as a function of three factors: (a) whether he had witnessed the deed; (b) whether his accusation was modalized by the verbcroire(‘think/believe’); and (c) whether the accusation was true or false. The results show that the four-and six-year-olds attribute certainty more often than the eight-year-olds. This dissymmetry is accompanied by a developmental progression in children's conceptions of these modal categories, which change from a ‘realistic’ conception (mainly based on truth/falsity) at four years to an increasingly metalinguistic and relativized conception thereafter.
Discourse and the acquisition ofeat
Authors: Rispoli Matthew 
Published: February 2009

ABSTRACTEnglish has several classes of transitive verbs which can optionally appear without an undergoer. Despite their similar syntactic sub-categorization, there are at least three different semantic subclasses that allow undergoer omission. Information sources based on surface structure, for example, syntactic bootstrapping, cannot inform the child of the semantic representation of these verbs. The focus of this paper is the acquisition of a single English verb,eat. The transcripts of 40 children, who were audiotaped monthly from 1;0 to 3;0, showed thateatwas the first member of this verb class to be acquired. Some 1276eatsentences were analysed for the presence of overt undergoer arguments across levels of cumulative verb lexicon (CVL) size, and two discourse conditions: (1) UNDERGOER ACCESSIBLE and (2) OPEN (to undergoer omission). Results indicate that undergoer omission became associated with discourse conditions when CVL size rose above 75 types, at MLU approximately 2·4 and age approximately 2;3. This suggests that two-year-old children are sensitive to a relationship between undergoer omission and discourse context.
Phonological characteristics of words young children try to say
Authors: Dobrich Wanda , Scarborough Hollis S. 
Published: February 2009

ABSTRACTTo examine the possible persistence of phonological selectional constraints on young children's lexical choices, the words attempted in the conversational speech of a longitudinal sample of 12 normally-developing preschoolers from age 2;0 to 5;0 were scored for syllabic length, presence of consonant clusters, and distribution of constituent phonemes. Except at the youngest ages, few developmental changes in target word characteristics were seen, and the observed differences were largely accounted for by syntactic, lexical, and pragmatic factors. The results suggest that selectional constraints persist only briefly in the course of language acquisition.
Mental terms in mothers' and children's speech: similarities and relationships
Authors: Furrow David , Moore Chris , Davidge Jane , Chiasson Lorraine 
Published: February 2009

ABSTRACTIn this study, mental terms in mothers' and their children's speech at two and three years of age were studied in order to examine the relationships between maternal and child use. Nineteen mother and child dyads were videotaped for one hour on each of two days when the children were 2;0 and again for two one-hour sessions on separate days when they were 3;0, and mental terms were noted. The utterances in which mental terms were used were coded for function. Results supported the existing picture of children's mental term use. Few terms appeared at 2;0, but many were used at 3;0 with think and know predominating. Mental terms occurred more commonly in utterances used to regulate the interaction between the participants than in utterances referring to mental states. Children's mental term use mirrored that of their mothers. Further, mothers' use of mental terms for particular functions when their children were 2;0 predicted their children's use at 3;0. While allowing no conclusions about causation, our findings suggest that the development of mental state language, and thus presumably a theory of mind, is fostered by the linguistic environment. Specifically, it is argued that the tendency of mothers to focus their children's attention on mental processes by talking about them and, more importantly, by using utterance types which conceivably direct the children to reflect on their own mental states, is associated with children's use of mental terms.
Can bilingual two-year-olds code-switch?
Authors: Lanza Elizabeth 
Published: February 2009

ABSTRACTSociolinguists have investigated language mixing as code-switching in the speech of bilingual children three years old and older. Language mixing by bilingual two-year-olds, however, has generally been interpreted in the child language literature as a sign of the child's lack of language differentiation. The present study applies perspectives from sociolinguistics to investigate the language mixing of a bilingual two-year-old acquiring Norwegian and English simultaneously in Norway. Monthly recordings of the child's spontaneous speech in interactions with her parents were made from the age of 2;0 to 2;7. An investigation into the formal aspects of the child's mixing and the context of the mixing reveals that she does differentiate her language use in con-textually sensitive ways, hence that she can code-switch. This investigation stresses the need to examine more carefully the roles of dominance and context in the language mixing of young bilingual children.
Morphosyntactic development in Italian and its relevance to parameter-setting models: comments on the paper by Pizzuto & Caselli
Authors: Hyams Nina 
Published: February 2009

ABSTRACTPizzuto & Caselli (1992) claim that data from the morphosyntactic development of Italian-speaking children are inconsistent with nativist, parameter-setting models of language development. In the present Note it is argued that much of the data which Pizzuto & Caselli adduce is irrelevant to the specific hypotheses they are evaluating and that those data which are relevant fully support parameter-setting and linguistictheoretic models, contrary to their claims.
Infant vocalizations and changes in experience
Authors: Hilke D. D. 
Published: February 2009

ABSTRACTThe possibility that infant vocalizations occur in conjunction with significant changes in experience was tested in a study of seven infants aged 0;8. Each infant was videotaped during an isolated freeplay session with each of three toys. Two indices of changing experience were used to identify portions of the tape where increased vocalizing was expected. The Place Index identified potentially significant changes in experience via major changes in locus of attention. The Reaction Index employed certain rapid changes in expression (e.g. smile, startle, browchange as indicators of corresponding changes in subjective experience. As predicted, periods of the tape encompassed by either or both of these indices evidenced significantly more vocalizations than remaining portions of the tape. Implications of these results for theories of infant communicative competence and for infant language development are discussed.
Between-word processes in child phonology
Authors: Stemberger Joseph Paul 
Published: February 2009

ABSTRACTMost processes in child phonology have as their domain a single word or a smaller chunk of phonological material. Processes that involve the interaction of two or more words have never been examined. In a diary study of the speech of one child acquiring English, there were eight between-word processes. All were optional and occurred in fairly restricted environments. Most of the processes were of short duration. Consequences for the study of child phonology are discussed.
Overextensions in early language comprehension: evidence from a signal detection approach
Authors: Behrend Douglas A. 
Published: February 2009

ABSTRACTTwo studies of children's early language comprehension were performed using the signal detection paradigm introduced by Thomas et al. (1981). Experiment 1 replicated the original findings of Thomas et al., demonstrating that 13-month-olds understand a word that a parent reported they would understand and did not understand a word that a parent reported they would not. In Experiment 2, the procedure was modified to test for overextensions in early language comprehension. On half of the trials, children saw an array of objects including a referent for a ‘known word’. On the other half, the array included an object perceptually similar to the referent of the known word, but which itself was not an appropriate referent (e.g. an apple instead of an orange). Though the children demonstrated an understanding of the known word, they also overextended that word to the inappropriate referent. Mechanisms for such overextensions are discussed, as is the general relationship between comprehension and production.
Linguistic input and early word meaning
Authors: Harris Margaret , Barrett Martyn , Jones David , Brookes Susan 
Published: February 2009

ABSTRACTFour mother–child dyads were videotaped in a longitudinal study of the relationship between linguistic input to children and early lexical development. Diary records were also kept by the mothers and, together with the videorecordings, were used to identify the contexts in which the children produced their first words. These were compared with the contexts in which the mothers used these same words. It was found that there was a strong relationship between the children's initial use of words and the most frequently occurring use of these words by the mothers. It was also found that although the majority of the children's first words were context-bound, a significant number were referential. The implications of these findings for current theoretical proposals concerning early lexical development are discussed.
Children learn from speech not addressed to them: the case of personal pronouns
Authors: Oshima-Takane Yuriko 
Published: February 2009

ABSTRACTA modelling experiment was conducted to determine if children would benefit from observing speech not addressed to them in discovering the correct use of first and second pronouns. Imitative behaviours of 18 English-speaking children who were about to learn personal pronouns were analysed under two modelling conditions. The non-addressee condition provided the child with systematic opportunities to observe the parents saying me/you with pointing actions directed towards each other as well as the parents saying me/you with pointing action directed towards the child. The addressee condition provided the child only with systematic opportunities to observe the parents saying me/you with pointing actions directed towards the child. Only children in the non-addressee condition imitated their parents' pointing actions and use of me/you without errors, suggesting that even children under two years old can attend to and can learn from speech not addressed to them.
Count/mass category acquisition: distributional distinctions in children's speech
Authors: Gordon Peter 
Published: February 2009

ABSTRACTThe count/mass distinction represents a categorical differentiation of nouns into count nouns which can be individuated when quantified (e.g. a car, several tables) and mass nouns which may not (cf. *a water, *several sands). The emergence of this distinction was examined in the longitudinal speech data of two children. In the first analysis, use of count nouns and mass nouns was compared in noun phrase contexts that require count nouns (e.g. a X, another X). It was found that from the earliest samples children used more count nouns in these contexts, hence showing a distributional distinction of noun types. This result suggests very rapid acquisition of count/mass subcategories. A series of further analyses assessed the possibility that early differentiation of count and mass nouns may be due to rote learning. No evidence was found for this proposal. A final analysis examined the development of a rule that requires that singular count nouns must be modified by a determiner. Acquisition here was found to be more protracted in nature since determiners are not used consistently in ‘telegraphic’ speech. Problems concerning the learnability of the obligatory determiner rule are discussed along with some speculations concerning the role of semantics in the acquisition of the count/mass distinction.
Cue validity in Hebrew sentence comprehension
Authors: Sokolov Jeffrey L. 
Published: February 2009

ABSTRACTThis study investigated the degree to which cue validity, as estimated from textual analyses, predicts the actual strength of grammatical cues as they are used by speakers of Hebrew. An experiment was conducted to determine the differential strengths of the linguistic cues employed by Hebrew speakers when assigning the role of patient in sentences. Monolingual Hebrew-speaking subjects 4, 5, 7, and 9 years old, as well as adults, were tested using a sentence-picture verification task. Six cues were included in the study: word order, the accusative object marker, the reflexive noun phrase and three verbal derivations. By presenting subjects with sentences which set these cues in competition with one another, a measure of the strength of each cue was obtained. The results of a regression analysis revealed strong positive correlations between estimated cue validities and actual cue strengths for all but the youngest age groups. These results were interpreted as suggesting that cue validity is highly predictive of actual cue strengths. In addition, the strengths of the six cues varied as a function of the subject's age. Two additional factors were hypothesized to account for the performance of the older subjects: increased sensitivity to the reliability of cues and discourse-based constraints.
Maternal speech to prelingual infants in Japan and the United States: relationships among functions, forms and referents
Authors: Morikawa Hiromi , Shand Nancy , Kosawa Yorio 
Published: February 2009

ABSTRACTMaternal speech to 3-month-old infants was compared for American and Japanese mother-infant dyads. Utterances were analysed at the levels of function, form and referent, and in relation to infant gaze direction. Loglinear categorical analysis revealed that infant gaze affected the intended functions of maternal speech differently for the two cultural groups. Cultural differences were also seen in the nature of function-form, and function-referent relationships. The differences seem to be consistent with culture-characteristic profiles of maternal behaviour towards older infants and children. It is suggested that transmission of culture through maternal speech starts at the earliest stage of infant development.
Early talk about the past: the origins of conversational stories of personal experience
Authors: Miller Peggy J. , Sperry Linda L. 
Published: February 2009

ABSTRACTThis paper explores children's early talk about specific distant past events and its development into conversational stories of personal experience, with special focus on its evaluative function. The data consist of longitudinal home observations of five working-class children and their mothers from ages 2; 0 to 2; 6. Results indicate that during this period the children talked primarily about negative past events, especially events of physical harm; the rate of talk about specific past events doubled; temporally-ordered sequences increased dramatically; and the children became better able to accomplish such talk independently. In addition, one of the most striking findings is the extent to which these 2–year-olds were able to communicate their attitude toward the past event, with speech about the past containing five times more evaluative devices than other speech. These results suggest that (1) by age 2; 6 stories of personal experience emerged in incipient form, and (2) the roots of this genre lie not only in cognitive skills and social interactional support but in the emotional significance of the depicted event.
