Development of coordination in the natural speech of young children
Authors: Lust Barbara , Mervis Cynthia A.
Published: September 2008

Natural speech of 32 young children from 2; 0 to 3; 1 (1·97 to 6·38 in MLU) was studied for evidence of use of coordination (by and). Analyses of the structure of coordinative expressions reflected development in structural variants as well as amount of coordination. Analyses suggested that early forms of coordination in natural speech reflected the same constraints which had been suggested by previous study of these children's language through an experimental elicited imitation task. A basis for a developmental theory of acquisition of coordination is sketched.
Language mixing in young bilinguals
Authors: Redlinger Wendy E. , Park Tschang-Zin
Published: September 2008

The speech of four two-year-old children growing up bilingually in a German-speaking community was studied for periods varying between five and nine months. An analysis of their language mixing revealed an initially higher rate of mixing which diminished with a growth in language development as measured in MLU. The data suggest that the children were at various stages in a gradual process of language differentiation thus providing support for the one-system theory of bilingual acquisition. An examination of the distribution of lexical substitutions by part of speech revealed that nouns were most frequently substituted by all children; however, more function words were substituted than content words overall.
Children's understanding of factive presuppositions: an experiment and a review
Authors: Scoville Richard P. , Gordon Alice M.
Published: September 2008

This paper presents a study of children's ability to recognize the presuppositions of sentences with factive and nonfactive verbs, and a review of recent research on the acquisition of factive presuppositions. In the present study, subjects in grades K, 2, 5 and 8, and adults, were asked to judge the truth of the complement clauses of sentences of the form ‘Doctor Fact (verb) that the ball is (is not) blue.’ The task was presented in the context of a television quiz show, with subjects as putative contestants. A tendency was found among younger subjects to overgeneralize the scope of negation of complement verbs into the main clauses of factive sentences. A gradual increase in comprehension of factive and nonfactive verbs was found, extending into adolescence. In a comparison of the present results with those of several recent studies, marked differences were found in the age of acquisition of factivity. These differences are discussed in terms of variations in task requirements and assessment techniques. It is concluded that acquisition proceeds on a verb-by-verb basis, rather than as a unitary process.
Homonymy in child phonology
Authors: Priestly Tom M. S.
Published: September 2008

The ‘fis phenomenon’ and similar anecdotal evidence, which appears to give insight into child phonology, and also certain experiments designed to reveal the nature of homonymy in child language, are discussed with reference to an approach which distinguishes between eight different types of possible phonetic episode. It is concluded that the anecdotes and experiments are less instructive than is often supposed.
Why we don't talk ‘baby talk’ to babies
Authors: Kaye Kenneth
Published: September 2008

The speech of 36 mothers to their infants in a face-to-face situation at ages 6, 13 and 26 weeks was compared with unfamiliar adults' speech to the same infants, the mothers' speech to an interviewer, and their conversations with the same children 2 years later. Speech to the infants was quite different from so-called ‘baby talk’, but contrary to other authors the speech to infants was even shorter, more repetitive, and more limited in content than the speech to language-learning children. Differences appear due to the infant's changing status in the relationship, from a potential to an actual conversant.
How to make sense of temporal/spatial ‘before’ and ‘after’
Authors: Feagans Lynne
Published: September 2008

Two experiments were devised in order to better understand the relationship between temporal before and after and their spatial counterparts. In Experiment I, sixty adults were probed for their spatial metaphoric understanding of temporal before and after. Although H. Clark proposed that temporal before and after were derived from their spatial counterparts, Experiment I did not support that notion. In fact, the subjects overwhelmingly reported that temporal before was more related to spatial after and that temporal after was more related to spatial before. Since it has been shown by numerous investigators that temporal before is acquired before temporal after by children, the evidence from Experiment I suggested that their spatial relatives may be acquired similarly. Experiment II presents evidence that indeed spatial after is understood better by three-year-old children than spatial before. This evidence is coincident with the adult reports in Experiment I.
Ambiguity of reference and listeners' reaction in a naturalistic setting
Authors: Hekken Suus M. J. Van , Vergeer Margretho M. , Harris Paul L.
Published: September 2008

The present study asked three questions. To what extent does the pre-school child use pronouns ambiguously in a naturalistic situation? Under what circumstances is such referential ambiguity likely to arise? How does the pre-school listener respond to such ambiguity? Sixteen pre-schoolers, four pairs of boys and four pairs of girls, were videotaped in a play situation. The results indicate that ambiguity of reference frequently arises, especially when disambiguation can be achieved only by verbal rather than non-verbal information. The presence of such ambiguity did not, however, influence the social responsiveness of the listener.
A comparative study of the use of pictures and objects in assessing children's receptive and productive language
Authors: Cocking Rodney R. , McHale Susan
Published: September 2008

A methodological study was designed to investigate two aspects of children's language knowledge and children's uses of pictures and objects when demonstrating their language skills. Sixty-eight 4- and 5-year-olds were randomly assigned to one of six treatment groups, matched for SES, sex, and age. Subjects were individually tested with one of the six measures: language comprehension using object stimuli; comprehension with picture stimuli; comprehension where there were choices among object stimuli; language production using object stimuli; production with picture stimuli; or production with choices among the object stimuli. Main effects for stimulus medium and response mode were both significant, as well as the interaction. The discussion is oriented towards the developmental controversy around receptive and productive language skills and the impact of the representational medium upon performance in assessment tasks.
The cognitive bases of relational words in the single word period
Authors: McCune-Nicolich Lorraine
Published: September 2008

Recent research on single-word language has focused on the acquisition of object words, considering relational words such as more, allgone, here, and up only peripherally. These words are considered in relation to the operative schemes of sensorimotor intelligence as suggested by Sinclair (1970). Relational words, like syntactic structure, appear to develop and exist apart from specific content. Study of such words helps clarify the relationship between sensorimotor understandings and the language of the pre-operational child. Data spanning the entire single-word period from five subjects provide an empirical base for analysing the meanings of these words in use. A model is then proposed for considering relational words as coding a set of interrelated meanings reflecting the cognitive organization of the late sensorimotor period.
Medial consonant cluster acquisition by Telugu children
Authors: Chervela Nirmala
Published: September 2008

This study is an attempt to trace the acquisition of consonant clusters by Telugu children. Phonemic inventories are given for each of the children for a clear picture of their acquisitional stage. It was found that reduction, substitution and assimilation played major roles in cluster acquisition. Co-occurrence restrictions and hierarchical application of the three phonological processes were noted. Results of this study are compared with similar works on Indian languages and English, and differences are pointed out.
Interactions between lexis and discourse in conservation and comprehension tasks
Authors: Sinha Chris , Carabine Bob
Published: September 2008

Research has indicated that both the lexical content and the discourse structure of the experimental instructions in traditional conservation tasks enhance task difficulty. Investigations of the comprehension of the relational terms more, less, same and different have revealed significant discourse and task demand effects upon comprehension strategies and cast doubt upon strong versions of hypotheses derived from linguistic marking theory. Five experiments were carried out on children aged between 3 and 6 years. Results were consistent with the following claims: (a) young children do not necessarily understand less to mean more, but do confuse the meanings of same and different; (b) function-based strategies of comprehension are superseded in development by attribute-based strategies for relating discourses to represented referents.
The development of directives: how children ask and tell
Authors: Bock J. Kathryn , Hornsby Mary E.
Published: September 2008

The ability to differentiate the directive senses of ask and tell was investigated using a production task in an experimental setting with children between the ages of 2; 6 and 6; 6. Results showed that the children at all ages distinguished the verbs along dimensions sensitive to adult ratings of politeness. There was a trend towards increased politeness with age under ask instructions, but not with tell instructions. Analyses of structural features of the directives produced showed that the interrogative form was more likely to be used with ask instructions, as was the word please, while tell instructions elicited the imperative, with less frequent use of please. The findings suggest that children before the age of 7; 0 are able to differentiate the illocutionary forces of utterances which have the same communicative intention.
Phonology and the development of the lexicon: evidence from children's errors
Authors: Vihman Marilyn May
Published: September 2008

Various kinds of children's lexical errors, mostly based on similarity in sound, are presented and classified. At the earliest stage some children are found to pursue a HOMONYM STRATEGY, actively seeking to combine adult word-patterns to limit their output repertoire. The associations between words underlying these productive homonyms, together with perception-based errors, blends, and other word-substitutions, are compared with malapropisms from a slightly older group of children as well as with data from adults. Analysis of these data makes it possible to chart developmental changes in the phonological links which form one substructure of the lexicon.
Complementary balance in the use of the interrogative form by nursery school dyads
Authors: Berninger Ginger , Garvey Catherine
Published: September 2008

Child partners were compared on their relative tendency to use the interrogative form in spontaneous dyadic verbal interactions. A given child's tendency to use the interrogative form more frequently than the other member of the dyad remained constant across partners. This relative stability in formulating utterances in interrogative form cannot be attributed to the child's producing more talk in general than the partner. The observed effect is explained as a type of conversational synchrony in which participants achieve a complementary balance rather than congruence. It was concluded that the interrogative form is a linguistic means for child peers to establish cooperation as well as controlling kinds of relationships during an ongoing interaction.
Pre-school children's use of the articles in definite and indefinite referring expressions
Authors: Emslie Hazel C. , Stevenson Rosemary J.
Published: September 2008

Three experiments investigated the ability of children aged 2; 2–4; 10 to use identifying expressions to introduce new referents and the definite article to refer to already introduced referents. The results suggest that young children initially master the nominative use ofa, but that from the age of 3 they have mastered the non-egocentric use of the definite article. On first mention their referring expressions are predominantly indefinite, and on second mention definite. The results are discussed in relation to previous studies, and the questions of suitable adult controls and ‘appropriateness’ of article usage are also considered.
Children's comprehension of pragmatic concepts expressed in ‘because’, ‘although’, ‘if’ and ‘unless’
Authors: Wing Clara S. , Scholnick Ellin Kofsky
Published: September 2008

First, third, and fifth graders judged a speaker's belief about entailment and propositional truth in sentences containing five subordinating conjunction-verb combinations: if, because, although, unless combined with indicative verbs, and if with a subjunctive verb. Children were more accurate when a speaker believed the truth of his utterance (because and although) than when he voiced disbelief (if + subjunctive) or doubt (unless and if + indicative). They were also more accurate in judging entailment when the speaker thought the events in the two clauses were positively related (if and because) than when the speaker expressed a negative relation (unless and although). The pattern of errors in judgement conformed to a pragmatic analysis of the conjunctions. First graders based their judgements on semantic cues and did not differentiate propositional truth and entailment concepts. Third and fifth graders understood the difference between entailment and propositional truth and used syntactic cues to differentiate positive from non-positive statements. However, they thought that a subordinating conjunction only determines belief about its own clause, and they did not understand the appropriate cues expressing uncertainty vs. disbelief.
Acquisition of bi-transitive sentences: pre-linguistic determinants of language acquisition
Authors: Osgood Charles E. , Zehler Annette M.
Published: September 2008

The present study concerned the acquisition of double-object, bi-transitive sentences which can be expressed in either BASIC (S-V-DO-to-IO) or TRANSFORM (S-V-IO-DO) constructions. Three-, four-, and five-year-old subjects were tested on comprehension and production of these two alternative forms, investigating the distribution of Basic and Transform sentences in acquisition, and also the effect of prototypicality of the described event on performance. The results showed that the Basic structure was earlier in acquisition, with the Transform appearing later and, at first, only in descriptions of the more prototypical events. Overall, the more prototypical an event, the more competent the children were in comprehension and production and the better able they were to handle the more difficult Transform sentences. Decreased prototypicality resulted in lower performance and greater dependence on the Basic as opposed to the Transform bi-transitives. The findings are discussed within the framework of a general theory of language performance being developed by the first author.
Mothers' responses to infants' object-related gestures: influences on lexical development
Authors: Masur Elise Frank
Published: September 2008

This paper examines four mothers' responses to three object-related gestures (pointing, extending objects, and open-handed reaching) by their first-born infants from 0; 9 to 1; 6, and the impact of their responses on the children's transition from gestural to verbal communication. Analysis revealed that the mothers responded differentially to their children's pointing gestures, reciprocating to a greater degree with labels of the indicated objects. The children, in turn, produced more object-labelling words with pointing than with other gestures. In addition, the mothers' labelling responses to pointing significantly predicted the extent of their children's object-naming vocabularies.
Intra-word phonological variability in young children
Authors: Leonard Laurence B. , Rowan Lynne E. , Morris Barbara , Fey Marc E.
Published: September 2008

Three experiments are reported which explored the conditions under which intra-word phonological variability occurs. Using an unsolicited imitation task, evidence of variability was obtained for words containing two or more phonological characteristics (consonants, word shapes) that were unstable in the child's speech, and for words containing both unstable characteristics and characteristics the child had not shown any evidence of producing with accuracy. Intra-word variability was most likely to occur when more than one aspect was in a state of instability or when one aspect was unstable and another was non-acquired. Words containing two phonological aspects not yet acquired by the child seemed to have little influence on variability. The findings indicate that variability can be attributed to (1) the presence of optional simplification processes, (2) the presence of more than one process applicable to a specific aspect of the word, (3) a competition between two aspects of the word for accurate surface realization, and/or (4) a competition between consonant approximation and word shape approximation.
Rule discovery in phonological acquisition
Authors: Fey Marc E. , Gandour Jack
Published: September 2008

Menn has suggested that most early phonological rules have the effect of reducing the variety of the child's phonetic output forms. This proposal is compatible with the Interactionist–Discovery (I–D) theory of phonological acquisition. This paper presents one child's unique phonological rule which increases output variety and yet still yields a mismatch with the adult form. Evidence is presented which indicates that the rule was a stable and productive part of the child's phonology and that it was both phonetically and phonologically motivated. It is argued that an addition to the early strategies described by Menn is needed to account, specifically, for the discovery of this unique rule and, generally, for later stages of phonological development.
Overextension and underextension in the child's expressive and receptive speech
Authors: Kay Deborah A. , Anglin Jeremy M.
Published: September 2008

The tendency of 30 children between the ages of 2; 0 and 2; 1 to overextend and/or underextend newly uttered, but previously understood words in comprehension and production was examined. It was found that both overextensions and underextensions occurred in comprehension and in production. Similarly, in both modes of speech children made more underextensions to peripheral than to central referents, and more overextensions to perceptually similar than to perceptually dissimilar nonreferents. The frequencies of overextensions and underextensions, however, were not the same in comprehension and production. Overextensions occurred more frequently in comprehension than in production, while conversely underextensions occurred more frequently in production than in comprehension. These data are discussed in terms of differences between children's and adult's word meanings, and between comprehension and production.
Immediacy and certainty: factors in understanding future reference
Authors: Harner Lorraine
Published: September 2008

Seventy-five children, 3, 4, and 5 years old, were interviewed about: (a) toys they had played with just a few minutes earlier, (b) toys they had played with on the preceding day, (c) toys they would play with in a few minutes, and (d) toys reserved for use on the following day. Verb forms indicating past and future time were used as well as the adverbials before and after. The past verb form was understood equally well in reference to the immediate past and the more remote past. However, the future verb form was better understood in reference to the immediate future than in reference to the remote future (the following day). The difference is discussed in terms of the intersection of time and mood in future verb forms. Immediacy of action and certainty of occurrence are suggested as early meaning components of future verb forms.
Verb-pattern alternation: the interface of morphology, syntax, and semantics in Hebrew child language
Authors: Berman Ruth A.
Published: September 2008

Verb-pattern alternation in Hebrew is characterized in terms of consonantal roots associated with a fixed set of morphological patterns in the lexicalized expression of categories such as causative, reflexive, inchoative and passive. It is assumed that at first Hebrew-speaking children will use a verb-root in one invariant pattern, and hence may also neutralize required morpho-semantic distinctions. Observational and experimental data from children aged 2; 6 to 5; 6 reveal a development in linguistic control of the system from non-alternation to near-mastery, with the concepts of causativity and distinctions in transitivity being lexicalized earlier than others. These findings are discussed in terms of the interplay between linguistic and conceptual development, and the evidence from language acquisition for linguistic theory.
Cross-linguistic perception in infancy: early effects of linguistic experience
Authors: Eilers Rebecca E. , Gavin William J. , Oller D. Kimbrough
Published: September 2008

The possibility that early linguistic experience affects infant speech perception was investigated in a cross-linguistic study with naturally produced speech stimuli. Using the Visually Reinforced Infant Speech Discrimination paradigm, three contrasts were presented to Spanish-and English-learning infants 6–8 months of age. Both groups of infants showed statistically significant discrimination of two contrasts, English and Czech. Only the Spanish-learning infants provided evidence of discrimination of the Spanish contrast. The groups discriminated the English contrast at similarly high levels, but the Spanish-learning infants showed significantly higher performance than the English on both the Spanish and the Czech contrast. The results indicate that early experience does affect early discrimination, and further (since the stimuli were natural) that the effect may be of practical consequence in language learning.
A morphemic measure of early language development: data from modern Hebrew
Authors: Dromi Esther , Berman Ruth A.
Published: September 2008

Given the nature of Hebrew as a highly synthetic language with rich bound morphology, an attempt was made to establish a measure corresponding to the MLU for a language such as English. The method of calculating MPU (morpheme-per-utterance) which is described here was tried out on 38 Hebrew-speaking children aged 2;0 to 3;0, and measured for internal consistency against different types of elicitation procedures, and for validity by comparison with the subjects' performance on a specially-devised measure of syntactic–semantic development. The results clearly indicate that the MPU is a useful developmental index of the linguistic proficiency of two- to three-year-old Hebrew speakers. Implications of this finding for intra-linguistic and cross-linguistic evaluation are then discussed.
The pragmatics of subordinating conjunctions: a second look
Authors: Scholnick Ellin Kofsky , Wing Clara S.
Published: September 2008

Some subordinating conjunctions reveal whether speakers believe the propositions the conjunctions connect and how speakers believe propositions are connected. Because and although express belief; if + indicative and unless uncertainty, and if + subjunctive, disbelief. Because, if + indicative and if + subjunctive express a positive entailment relation between clauses while although and unless express negative entailment. To validate this analysis a comprehension task was administered to 96 subjects divided among 9-, 11- and 19-year-olds. Nine-year-olds understood although and because while adults also comprehended unless and if + indicative. Generally the more positive beliefs the conjunction embodied, the easier its comprehension. The order of difficulty was because, although, if + indicative, unless, and if + subjunctive. Older subjects more often confused if + subjunctive with if + indicative. Understanding of the uncertainty conveyed by if + indicative and unless was linked to performance on a task of detecting uncertain outcomes.
Talking backward: exceptional speech play in late childhood
Authors: Cowan Nelson , Leavitt Lewis A.
Published: September 2008

The game of ‘talking backward’, invented independently by two boys aged 8; 10 and 9; 11, is studied with reference to the role of speech play in linguistic, cognitive, and social development. Case reports from 27 adult backward talkers suggest a lower limit of about 7 years for the onset of this ability. The backward speech of the two children illustrates how either phonology or orthography can be used as a basis for backward speech, and demonstrates the boys' knowledge of phonemic units and letter-to-sound correspondences. Talking backward belongs to a larger class of ‘secret’ language games that may be cognitively and pragmatically well suited to children of this age.
Adapting syntax in writing to varying audiences as a function of age and social cognitive ability
Authors: Rubin Donald L.
Published: September 2008

Fourth-, eighth-, twelfth-graders and expert adults each wrote persuasive messages to three audiences arrayed along a dimension of intimacy to writer. Measures of social cognitive ability were also obtained. Scripts were analysed for (1) fluency, (2) subordination, (3) clause length, (4) logical adverbial clauses, and (5) conjunctions of conclusion. In addition to general developmental trends, results indicated effects of audience adaptation and of mediation of social cognitive ability. Findings support the view that evidence of later language development must be interpreted in light of communicative demands of tasks and subjects' rhetorical skills.
Style and stability in mother conversational behaviour: a study of individual differences
Authors: Olsen-Fulero Lynda
Published: September 2008

This paper explores differences in conversational style among mothers. Although previous research suggests that many aspects of mother speech to the child covary in a way which serves the underlying intention of the mother, it was unclear whether such clusters of conversational behaviour would prove useful in characterizing stylistic differences among mothers across time. An analysis of the functionally-coded speech of 11 mothers showed statistically significant variability among mothers, especially in those behaviours most closely associated with intention. Further, mothers showed stability in these behaviour patterns across two sessions. A typology of mother style, based on the intentions of mothers to direct or converse with their children, is suggested and illustrated by individual cases.
The speech of two- and three-year-olds to infant siblings: ‘baby talk’ and the context of communication
Authors: Dunn Judy , Kendrick Carol
Published: September 2008

Adjustments in speech made by 2- and 3-year-old children when talking to their 14-month-old siblings are described and compared with those made by mothers addressing their babies. ‘Clarification’ adjustments were made by all the children, but there were marked individual differences in the frequency of questions and ‘affective-expressive’ features – differences related to the quality of the relationship between the siblings. The pattern of speech adjustments reflected the social contexts in which the children addressed their siblings; within these contexts (prohibitory and playful) children as young as 2 make appropriate use of communicative devices. The individual differences between the children indicate two sources of influence on the adjustments made – pragmatic and emotional.
Experimental evidence for agent–patient categories in child language
Authors: Angiolillo Carl J. , Goldin-Meadow Susan
Published: September 2008

Evidence provided by contrastive word order for agent and patient semantic categories in young children's spontaneous speech is confounded. Agents (effectors of the action) tend to be animate; patients (entities acted upon) tend to be inanimate. In an experiment designed to circumvent this confounding and to test young children's linguistic sensitivity to the role an entity plays in the action, nine children (2; 4·0–2; 11·5) described actions involving animate and inanimate entities playing both agent and patient roles. Four linguistic measures were observed. On every measure agents were treated differently from patients. For the most part, these agent–patient differences persisted when animate and inanimate entities were examined separately. These results provide evidence for the child's intention to talk about the role an entity plays, independent of its animateness, and also suggest that the child uses role-defined linguistic categories like AGENT and PATIENT to communicate these relational intentions.
Up front: the acquisition of a concept and a word
Authors: Levine Susan Cohen , Carey Susan
Published: September 2008

Thirty-six 2- to 3-year-old children were given linguistic and non-linguistic tasks in order to determine whether the words front and back introduce the concept of ‘front–back’ orientation or whether the concept precedes the words. Contrary to prediction, a complex disjunctive concept of ‘front–back’ orientation was found to precede any knowledge of the words front and back. Results of the linguistic task show that the word back is comprehended before front, and further that children at an intermediate state of lexical knowledge interpret front as if it means back.
Acquisition of epistemic and deontic meaning of modals
Authors: Hirst William , Weil Joyce
Published: September 2008

Modal auxiliaries have an epistemic and deontic sense and range in strength, e.g. must propositions are stronger than may propositions. Children (ages 3; 0–6; 6) heard two contradictory modal propositions of varying strength. In the epistemic condition, the propositions concerned the location of a peanut. In the deontic condition, they were commands by two teachers about what room a puppet should go to. The child was to indicate which command should be followed. The general acquisitional rule was: the greater the difference in the strength of the two modal propositions the earlier the difference was appreciated. Since the acquisitional history was similar across conditions, the two senses probably arose from a single lexical entry.
Mothers' speech to prelingual infants: a pragmatic analysis
Authors: Penman Robyn , Cross Toni , Milgrom-Friedman Jeannette , Meares Russell
Published: September 2008

Functional and referential changes in maternal speech were investigated in a developmental study of nineteen mother–infant dyads, using video recordings of their free play at three and six months. The role of the infant in influencing speech adjustments was investigated by analysing the relationships between different types of maternal speech and different infant behavioural modes. Three general modes were differentiated – Communicative, Praxic and Other – and, regardless of infant age, mothers were found to make some modifications to their speech style as a function of infant mode. Speech style also was found to change, at a pragmatic level, from three to six months. Both findings support the conclusion that maternal speech is influenced by non-linguistic behavioural ‘feedback’ from infants. However, a finding that affect-oriented speech is more sensitive to infant behaviour than informative speech supports Brown's (1977) contention that the maternal speech register is shaped by two relatively independent interpersonal functions – the affective and communicative components. It is argued that a fuller account of maternal conversational adjustments to prelingual infants requires both a dialogic and a monologic explanation.
The relationship of pragmatic dimensions of mothers' speech to the referential-expressive distinction
Authors: Corte Maria Della , Benedict Helen , Klein Diane
Published: September 2008

A 50-utterance corpus for each of sixteen mothers during caretaking situations (diapering, dressing, bathing) was extracted from in-home tape recordings obtained over a three-day period. The children ranged from 1; 3.15 to 1; 7 and were classified according to Nelson's referential-expressive distinction. A coding scheme consisting of three categories – communicative intent, focus of attention and evaluation – was employed to characterize the mothers' speech. Mothers of referential children produced a greater number of utterances per caretaking incident, more description and less prescriptives than did mothers of expressive children. The findings suggest that Nelson's referential-expressive distinction in child's speech is related to differences in mothers' pragmatic speech characteristics.
Children's judgements of the functional acceptability of referential communications in discourse contexts
Authors: Ackerman Brian P.
Published: September 2008

This study determined whether young children are sensitive to the contextual influence of previous discourse on judgements of the adequacy of referential communications. Four- and six-year-old children were read short stories containing terminal referential communications that were either ambiguous or informative relative to a perceptual display of candidate-referential objects. Contextual information was given in the story prior to the terminal communication that was irrelevant to the ambiguous communications or that made these communications functionally informative. The subjects were required to say whether the listener in the story could identify one unique referent. The results showed that the judgements of both groups of children were sensitive to the discourse context of the communications. The children discriminated between the functionally informative and ambiguous communications.
Comprehending surface and deep structure subjects: children's understanding of implied vs. explicitly stated nouns
Authors: White Hedy
Published: September 2008

Previous research indicates young children are likely to interpret the surface-structure subject of a sentence as the deep subject regardless of syntax, e.g. John is chosen as subject of both John is easy to please and John is eager to please. However, with one-noun sentences, the task required both recognizing a difference between the sentences and inferring an implied noun. Thus an inability to make an inference might be responsible for the children's consistency in choosing the surface subject. Two experiments compared kindergarteners' interpretations of one- and two-noun sentences. With two-noun sentences (i.e. John is easy for Jim to please), which explicitly stated the surface object, consistency in choosing the surface subject decreased.
Child responsiveness to mother questions of varying type and presentation
Authors: Olsen-Fulero Lynda , Conforti Jill
Published: September 2008

Although questions vary considerably with respect to the responses appropriate to them and the motivations intrinsic to them, little attention has yet been given to the potential effects of these factors on the power of questions to perform turn-allocating and response-eliciting functions. The present study attempts to clarify how such variables as motivation, constraint, difficulty and function may affect the child's responsiveness to mother questions. Results suggest that functionally defined question types are differentiable not only by their relative power to elicit a response from the child, but also by the manner in which they are presented. Implications of these results in the context of mother–child conversation and its effects are considered.
Linguistic experience modifies lexical stress perception
Authors: Allen George D.
Published: September 2008

Sensitivity to differences in lexical stress pattern was examined in 4- and 5-year-old monolingual French-, German- and Swedish-speaking children. For most stimulus discriminations, the 5-year-olds outperformed their 4-year-old comparison groups. For a discrimination involving a trisyllabic distinction not found in French, however, the French 5-year-olds performed worse than their 4-year-old compatriots, suggesting that the older children had ‘learned’ not to hear the trisyllabic distinction. In follow-up testing of the French 4-year-olds six months later, half of them showed a similar decrease in performance specific to the trisyllabic stimuli. These data support an ‘attunement’ theory of language acquisition, in which potentially relevant abilities that are already partially or fully developed at birth may become attenuated or completely lost if they are inappropriate or irrelevant for the child's language.
Turn the page please: situation-specific language acquisition
Authors: Snow Catherine E. , Goldfield Beverly A.
Published: September 2008

The present paper investigates a strategy for language acquisition adopted by one child, and the usefulness of book-reading in supporting that strategy. Conversations between this child and his mother around picture-book reading were recorded and recurrent discussions of the same picture were analysed. A coding scheme was devised which identified each speaker's contribution to the exchange of information about a particular picture. By examining recurrent picture discussions, it was possible to trace the child's acquisition of the linguistic means for talking about a given picture. It was found that specific lexical items and constructions used to talk about a picture frequently recurred in subsequent discussions, and that the child learned many of these same items and constructions. Furthermore, he was most likely to acquire what he had heard his mother say about a picture if he had repeated it in an earlier discussion. The usefulness of routines for such situation-specific learning and the implications of the situation-specific approach for future investigations of input language are discussed.
Mothers' use of superordinate category terms
Authors: Shipley Elizabeth F. , Kuhn Ivy F. , Madden E. Colby
Published: September 2008

Mothers' speech in an identification task was examined for ten mother–child pairs in which the child's age varied from 1; 9 to 4; 9. Stimuli were used from three domains, animals, clothes and furniture. These varied in familiarity, centrality (goodness of exemplar) and number of items. Basic-level category terms were found to be the most frequently used labels. Superordinate category terms were elicited by (a) an unfamiliar animal and (b) groups of items from the same domain. Information on category relations was provided in several ways: alternative labels, multiple labels and explicit statements of inclusion. Competencies required to learn the correct referent for category terms and differences among superordinate categories are discussed.
Imitations, interactions, and language acquisition
Authors: Stine Elizabeth Lotz , Bohannon John Neil
Published: September 2008

The precise function of imitation in children's speech is still debated. Two hypotheses have been offered that focus on either the progressive nature of imitation to aid in the language acquisition process or the social, conversational role played by imitation in discourse. Support for these positions was sought in the imitations within the speech of a single child at ages 2; 8 and 3; 0. Evidence is presented for both roles of imitation in language acquisition. First, imitation aids in limiting the complexity (MLU) of the language environment. The effects of imitation in this role are compared and contrasted to the effects of the child's productions of what? Also, forms may appear in imitation prior to their appearance in spontaneous speech. A model is proposed in which imitation and what?-responses are overlapping phases of language acquisition which occur prior to spontaneous production of a given form.
Evaluating presuppositions and propositions
Authors: Scholnick Ellin K. , Wing Clara S.
Published: September 2008

Some conjunctions simultaneously convey speakers' presuppositions about the validity of propositions uttered and assertions of particular interclausal relations. Because conveys belief, if + indicative, uncertainty and if + subjunctive, disbelief. While all three conjuctions assert positive entailment, unless, which like if + indicative presupposes uncertainty, asserts negative entailment or denial. The relationship between pragmatic knowledge and reasoning was explored by asking 12 males and 12 females at each of three ages (12, 15, adult) to solve written syllogisms containing the four conjunctions and evaluate single sentences for their pragmatic content. In the pragmatic task, belief was easier to detect than uncertainty or disbelief. Positive entailment was easier than negative entailment. Only entailment influenced syllogistic reasoning with unless harder than the positively entailed conjunctions. At each age linguistic comprehension of negative entailment was related to understanding valid implications in unless syllogisms. The relation between comprehension of pragmatic uncertainty and detection of uncertain conclusions in reasoning increased with age.
Discernible differences in the babbling of infants according to target language
Authors: Boysson-Bardies Bénédicte De , Sagart Laurent , Durand Catherine
Published: September 2008

Samples of babbling productions of 6-, 8- and 10-month-old infants from different language backgrounds were presented to adult judges whose task was to identify the infants from their own linguistic community. The results show that certain language-specific metaphonological cues render this identification possible when the samples exhibit long and coherent intonation patterns. The segmental indications that are present in the fully syllabic productions of canonical babbling do not allow the judges to identify the infants correctly from their own linguistic community. These results seem to support the hypothesis of an early influence on babbling of the metaphonological characteristics of the target language.
Brown & Hanlon revisited: mothers' sensitivity to ungrammatical forms
Authors: Hirsh-Pasek Kathy , Treiman Rebecca , Schneiderman Maita
Published: September 2008

Brown & Hanlon (1970) reported that parents' explicit approval or disapproval of their child's utterances was not contingent on the well-formedness of that utterance. Rather, parents seemed attuned to the semantic value of their child's speech. Using 40 mother–child dyads, 10 from each of four age groups, 2–5 years, we replicated these results. We expanded upon this earlier work, however, to suggest that parents are not totally indifferent to the grammatical form of their child's utterances. Focusing on repetitions, we found that mothers are more inclined to repeat ungrammatical than grammatical sentences generated by 2- year-old subjects. This indicates that the language learning environment does present subtle cues that distinguish between well-formed and ill-formed sentences. Whether the child is capable of capitalizing on these cues remains unanswered.
Children's capacity to correct grammatical violations in sentences
Authors: Pratt Chris , Tunmer William E. , Bowey Judith A.
Published: September 2008

Previous studies of children's knowledge of grammatical well-formedness have typically involved eliciting acceptability judgements from children. In the present study, children were expected to employ their tacit knowledge of the rules of grammar to correct sentences containing grammatical rule violations. Two groups of children (mean ages of 5;5 and 6;4) were presented with ungrammatical sentences resulting from either word-order changes or morpheme deletions. The results indicated that both groups of children performed well when presented with ungrammatical sentences containing morpheme deletions; but the performance of both groups was lower for the word-order violations, with the difference between the two types being greater for the 5-year-olds. It is argued that these results reflect differences in the extent to which the two types of rule violations rendered the original sentences meaningless.
A developmental cross-linguistic study of adversative connectives: French ‘mais’ and German ‘aber/sondern’
Authors: Kail Michèle , Weissenborn Jürgen
Published: September 2008

This study concerns the acquisition of the meaning of adversative connectives in French and German children from 7; 8 to 9; 11. French mais has both a substitutive and a contrastive use which is expressed by two different connectives in German, i.e. sondern and aber. 36 French and 36 German children were tested in a completion and a judgement task. Two hypotheses are confirmed: (a) substitutive but is easier to process and hence is acquired earlier than contrastive but; (b) the interpretation of contrastive but-sentences depends on their inferential complexity relative to a given context. A third assumption about the facilitative effect of lexical differentiation in German was only partially supported by the data. This issue needs further investigation with more languages and younger children.
Expression of the part–whole semantic relation by 3- to 12-year-old children
Authors: Litowitz Bonnie E. , Novy Forrest A.
Published: September 2008

The present study investigated the expression of the part–whole semantic relation by children 3 to 12 years of age. Controlling both task format (structured vs. open-ended) and dimensions associated with experimental stimuli (part-word vs. part-object; known whole vs. unknown whole), the verbal responses of two age groups of children were analysed. While results revealed the part–whole semantic relation expressible by even the youngest children, age-group comparisons indicated that the older children preferred its use significantly more often. The part–whole semantic relation was also observed to take several linguistic forms (partitive, spatial, possessive), the selection of which varied as a function of age, task format, and type of experimental stimuli. Findings are discussed relative to issues concerning research methodology, the elicitation and assessment of children's semantic knowledge, and cognitive developmental theory.
The acquisition of voicing contrasts in Spanish and English learning infants and children: a longitudinal study
Authors: Eilers Rebecca E. , Oller D. Kimbrough , Benito-Garcia Carmen R.
Published: September 2008

The production of voice-onset time (VOT) was studied in a group of Spanish- and English-learning subjects at 1 and 2 years of age. Voice-onset time of initial stop consonants from canonical utterances was measured oscillographically. At one year no significant difference in VOT production was found between Spanish and English learners at any place of articulation. Mean VOT values for infants fell in the short lag range. By two years, four of the seven children in the English group and four of the children in the Spanish group showed significant evidence of having acquired the VOT distinction in stop consonants appropriate for their native language.
