The role of speech discrimination in developmental sound substitutions
Authors: Eilers Rebecca E. , Oller D. Kimbrough 
Published: September 2008

ABSTRACTFourteen two-year-olds (M=2; o) were presented with minimal word pairs in a new and highly efficient experimental perception paradigm. The data provide a preliminary view of the relative difficulty of various minimal phonological contrasts for children. The study specifically focuses on perception of some phonological contrasts which usually are actualized and some which usually are not actualized in two-year-old child productions. The data suggest that perceptual difficulties probably play a substantial role in some childhood speech errors, but little, if any, role in others.
The acquisition of the passive voice
Authors: Baldie Brian J. 
Published: September 2008

ABSTRACTThe study was aimed at determining the average ages at which children imitate (I), produce (P) and comprehend (C) passive constructions. The results were compared with those obtained from partial studies of the acquisition of the passive voice conducted by researchers such as Fraser, Bellugi & Brown (1963). The finding that imitation precedes comprehension which in turn precedes production (I > C > P), as reported by Fraser et al. (1963) for 12 three-year-olds, is confirmed in this study for children from 3; 0 to 8; 0. The ability to use the passive voice in various tasks was found to be generally greater than that suggested in previous studies.
Stages of egocentrism in children's use of ‘this’ and ‘that’: a different point of view
Authors: Webb Pamela A. , Abrahamson Adele A. 
Published: September 2008

ABSTRACTAcquisition of the words this and thatwas tested by a comprehension and a production task with children of ages 4 and 7. In the comprehension task, children had to choose one of two toys requested by the experimenter. Child and experimenter were seated either side by side or facing one another. It was expected that children would first learn the spatial contrast between the two words and then learn to apply it from the speaker's point of view, according to developmental stages similar to those found in other studies of spatial non-egocentrism. The prediction was confirmed, but comparison with the results of de Villiers & de Villiers (1974) suggests an alternative theoretical analysis, in which non-egocentrism is not necessary for correct use of this and that. A second prediction, that performance would be better on the unmarked word that, was not confirmed for the side-by-side condition. In the production task, only 2 of the 60 children violated the restriction that this can refer only to near objects.
Comprehension and production of adjectives and seriation
Authors: Ehri Linnea C. 
Published: September 2008

ABSTRACTTo explore adjective language development and to examine its relationship to seriation, several tasks were given to 40 children aged 4;0 to 8;0. Comprehension and production of various adjective forms were measured: vocabulary, coordination, comparison. The ability to order objects by size was used to assess intuitive-level seriation. In addition to yielding information about children's meanings and use of adjective forms, results indicated that vocabulary and comprehension were more important than language production for distinguishing senators from non-senators. The relevance of findings for Sinclair de Zwart's observations and for the Clarks' hypotheses about adjective development is discussed.
Language development as related to stage 6 object permanence development
Authors: Corrigan Roberta 
Published: September 2008

ABSTRACTA longitudinal study of three children examined the relation between object permanence and language development. Unlike other studies, an independent measure of object permanence development was provided. While there was not a one-to-one correspondence between object permanence and language, there were relations at certain points in development. There was a rough relationship between the onset of stage 6 of object permanence and the onset of single-word utterances. Total vocabulary showed a large increase around the time of entrance into the preoperational period of object permanence development. At the same time, the semantic categories Nonexistence and Recurrence appeared. No differences were found in the use of function forms and substantive forms before object permanence development.
Tone acquisition in Cantonese: a longitudinal case study
Authors: Tse John Kwock-Ping 
Published: September 2008

ABSTRACTThere have been relatively few studies on tone acquisition, as compared to studies on the acquisition of segmentals, morphology, and syntax. Still fewer are the studies on Chinese language acquisition. The present paper reports on a longitudinal case study of a Cantonese-speaking child aged 2; 8 and considers the implications of tone acquisition for tone studies in general, and Cantonese tonology in particular.
Preschool children's intraconversational narratives
Authors: Umiker-Sebeok D. Jean 
Published: September 2008

ABSTRACTAnalysis of narratives produced spontaneously within natural conversation by children from three to five years of age found age-related increases in length, number, variety, compression, and complexity of six story elements, remoteness of narrated events, and number and variety of intra- and post-narrative listener responses made to them. These and other changes indicate a considerable growth from three to five in the amount and sophistication of information furnished by preschool narrators, particularly between three and four years, as well as in the motivation of the stories with respect to the overall conversational discourse.
Social class differences and the identification of sex in children's speech
Authors: Edwards John R. 
Published: September 2008

ABSTRACTJudges were asked to identify the sex of prepubertal children by listening to their tape-recorded voices. More incorrect guesses were made of working class girls than of their male counterparts. For middle-class children, however, the pattern was reversed, with more boys being misidentified as girls than the opposite. These findings are related to work demonstrating an association between masculinity and working-class speech, and to the ‘covert prestige’ attaching to such speech as a result. Some practical implications of the results for researchers in the field of child language are also discussed.
‘What says meow?’. The role of context and linguistic experience in very young children's responses to what-questions
Authors: Allen Rhianon , Shatz Marilyn 
Published: September 2008

ABSTRACTChildren aged 1; 4 to 1; 6 were asked common what/-questions under four different contextual conditions. The presence of a gesture was found to have a significant effect on the nonverbal components of children's responses, while linguistic sophistication and type of question asked affected vocal responses, but did not produce any consistent effects on nonverbal responses. Results are interpreted as suggesting that, at this early age, gestural information is processed relatively independently of speech. These findings cast doubt on the likelihood that maternal gestures facilitate early language responding. Case-study observations of the children's interactional behaviour with mothers suggest instead that prior experience with verbal routines was a factor in the children's experimental vocal performance.
‘Do what I mean, not what I say!’. Changes in mothers' action-directives to young children
Authors: Schneiderman Maita H. 
Published: September 2008

ABSTRACTThis study investigated mothers' notions of appropriate speech to 40 children aged 1; 6 to 3; 6. Spontaneous maternal action-directives were analysed in terms of the explicitness with which they expressed syntactic and lexical clues to action-directive intentions. Cross-sectional and longitudinal changes, and progressions within maternal repetition sequences, indicated that the children perceived as most limited in inferential skills elicited the most restricted input. Most of the action-directives they heard could be interpreted non-inferentially, because syntactic and lexical clues to intentions were explicitly expressed. External supports were removed gradually in response to the mother's perception of her child's increasing ability to draw extra-linguistic inferences. Several theoretical models of non-literal speech-act comprehension are supported. It is argued that the differences in language use reflect the mother's notions of the speech a listener is likely to understand.
Error assimilation as a mechanism in language learning
Authors: Platt Carole Butler , MacWhinney Brian 
Published: September 2008

ABSTRACTThe present study tests the hypothesis that many of the grammatical errors that occur during the course of language development can serve as ‘auto-input’ leading directly to the acquisition of new expressive forms. A free-speech corpus of grammatically incorrect sentences was gathered from each of 4 four-year-old subjects. Three additional sets of sentences were constructed: sentences containing errors similar to those actually produced, sentences containing ‘baby errors’ and correct sentences. The children were asked to judge these sentences as correct or incorrect. Significantly fewer corrections were made in the sentences with subject-generated errors than in the sentences with similar errors or ‘baby errors’. These results can be explained by assuming that children learn their own errors.
More negative findings for positive prepositions
Authors: Abkarian G. G. 
Published: September 2008

ABSTRACTThree- and four-year-old children were tested on their comprehension of the locative prepositions in front of, in back of, ahead of, and behind. Results demonstrated that those prepositions characterized as positive by H. Clark (1973) were, contrary to theoretical predictions, comprehended more poorly than their ostensibly negative counterparts. Discussion of the possible reasons for these findings is included.
Phonological constraints on the emergence of two-word utterances
Authors: Donahue Mavis 
Published: September 2008

ABSTRACTConsiderable interest has been generated concerning linguistic and cognitive factors influencing the onset of early combinatorial speech. The present diary study provides evidence that, for some children, the transition between the single-word and two-word stages may be governed by phonological constraints. The presence of a phonological selection strategy and consonant harmony rule in one child's developing phonological system is described. Evidence is presented suggesting that this consonant harmony constraint operated across morpheme boundaries. This had the effect not only of delaying the onset of two-word utterances, but also of influencing the selection of words that could occur in word combinations. The implications of these findings for explaining individual variation in the transition from single-word to combinatorial speech are discussed.
Belief and quantity: three-year olds' adaptation to listener's knowledge
Authors: Perner Josef , Leekam Susan R. 
Published: September 2008

ABSTRACTTwo groups of 3-year-old children (3:0–3;6 and 3;6–4;0) observed two actions of a toy. In one condition an older partner was absent while the subject watched both of the toy actions (fully ignorant partner), whereas in the other condition the partner witnessed one of the two actions together with the subject (partially ignorant partner). When asked about the toy's actions by their partially ignorant partner both age groups adjusted their answers to their partner's ignorance and mentioned only that action which was new to their partner. However, in their answers to their fully ignorant partner the younger children tended to provide insufficient information by mentioning only one instead of both actions.
Directionality preferences in the interpretation of anaphora: data from Korean and Japanese
Authors: O'Grady William , Suzuki-Wei Yoshiko , Cho Sook Whan 
Published: September 2008

ABSTRACTRecent work by Lust and others has led to the prediction that children acquiring left-branching languages will exhibit a preference for backward patterns of anaphora. In this paper, we test this prediction against data from Korean and Japanese and show it to be false. An alternative hypothesis proposing a preference for forward patterns of anaphora is outlined and possible explanations for earlier experimental results supporting Lust's prediction are considered.
Lexical acquisition and acquisition of initial voiceless stops
Authors: Tyler Ann A. , Edwards Mary Louise 
Published: September 2008

ABSTRACTThe interaction between lexical acquisition and acquisition of initial voiceless stops was studied in two normally developing children, aged 1;9 and 1;10, by acoustically examining the token-by-token accuracy of initial voiceless stop targets in different lexical items. Production accuracy was also examined as it related to the frequency of usage of different words, as well as the time when they entered the children's lexicons. Fewer than half of the words in the children's lexicons had tokens representing the emergence of accurate voiceless stop production prior to the session at which the voicing contrast was achieved. These words were primarily ‘old’ words that had been in the children's lexicons from the beginning of data collection, as opposed to ‘new’ words, first produced in later recording sessions. Findings are discussed in reference to the ‘lexical diffusion’ model of sound change and within the framework of nonlinear underspecification theory.
Issues in the acquisition of the Sesotho tonal system
Authors: Demuth Katherine 
Published: September 2008

ABSTRACTThis paper examines the acquisition of the grammatical tone system of Sesotho, a southern Bantu language where tone sandhi is rich, and where surface and underlying representations are often quite distinct. Results of the longitudinal case study show that rule-assigned tone on subject markers is generally marked appropriately by age two. In contrast, underlying tonal representations on verb roots are learned gradually over time, showing an early Default High tone pattern. The study also finds that, while some tone sandhi rules are in the process of being acquired between 2;6 and 3;0, problems in the mapping between tonal representations and segments persist. The paper raises methodological and theoretical issues not only for the acquisition of tonal systems, but for the acquisition of phonology in general.
The relation of maternal language to variation in rate and style of language acquisition
Authors: Hampson June , Nelson Katherine 
Published: September 2008

ABSTRACTThe main thrust of this paper is to question whether in earlier studies the ‘motherese hypothesis’ has been adequately tested. The present study first explores concurrent relations between maternal and child language at an early age, using the Soyder, Bates & Bretherton (1981) questionnaire to assess vocabulary at 1;1. With a large sample of 45 subjects, videotaped at 1;1 and 1;8, it was possible to analyse earlier talkers separately from later talkers. The results indicate pre-existing differences between the mothers of earlier and later talkers as early as 1;1 – some 5 months before other studies have examined the possible facilitative effects of ‘motherese’. Secondly, and perhaps more importantly, when the sample was divided according to stylistic preference at 1;8, several associations between maternal language at 1;1 and MLU at 1;8 emerged for the non-expressive group which were non-existent for the expressive group. These results imply that earlier studies may have been looking for the effectiveness of maternal input too late. Moreover, it may continue to be difficult to demonstrate consistent effects of child-directed speech as long as researchers continue to ignore individual differences in style of language acquisition.
Infants' ability to consult the speaker for clues to word reference
Authors: Baldwin Dare A. 
Published: September 2008

ABSTRACTThis research examines whether infants actively seek information from a speaker regarding the referent of the speaker's utterance. Forty-eight infants (in three age groups: 1;2–1;3, 1;4–1;5, and 1;6–1;7) heard novel labels for novel objects in two situations: follow-in labelling (the experimenter looked at and labelled the toy of the infant's focus) vs. discrepant labelling (the experimenter looked at and labelled a different toy than that of the infant's focus). Subsequently, half of the infants were asked comprehension questions (e.g. ‘Where's the peri?’). The other half were asked preference questions (e.g. ‘Where's the one you like?’), to ensure that their comprehension performance was not merely the result of preferential responding. The comprehension results revealed developmental change in both (a) infants' ability to establish new word-object mappings (infants aged 1;2–1;3 failed to establish stable word-object links even in follow-in labelling), and (b) infants' ability to pinpoint the correct referent during discrepant labelling (only infants aged 1;6–1;7 succeeded). Thus the period between 1;2 and 1;7 represents a time of change in infants' ability to establish new word-object mappings: infants are becoming increasingly adept at acquiring new labels under minimal learning conditions.
Phonological and morphological analysis skills in young children
Authors: Smith-Lock Karen M. , Rubin Hyla 
Published: September 2008

ABSTRACTTwenty-two normally developing five-year-olds were asked to judge, identify, repair and explain phonological and morphological errors. All of the errors involved the addition, substitution or omission of a single phoneme, which in the morphological task, was also an inflectional morpheme. Stimuli were controlled for type of error (omission, addition, substitution), location of the error (word final) and word status of the resulting error (word, non-word). Children performed significantly better on the phonological task than on the morphological task. It is proposed that the results are due to differences in the type and location of linguistic information to be analysed and to differences in memory demands in the tasks.
Joint picture-book reading correlates of early oral language skill
Authors: Debaryshe Barbara D. 
Published: September 2008

ABSTRACTThe purpose of this study was to explore the relation between joint picture-book-reading experiences provided in the home and children's early oral language skills. Subjects were 41 two-year-old children and their mothers. Measures included maternal report of the age at which she began to read to the child, the frequency of home reading sessions, the number of stories read per week, and the frequency of visits by the child to the local library. Measures of language skill used were the child's receptive and expressive scores on the revised Reynell Developmental Language Scales. Multiple regression analyses indicated that picture-book reading exposure was more strongly related to receptive than to expressive language. Age of onset of home reading routines was the most important predictor of oral language skills. Directions of effect, the importance of parental beliefs as determinants of home reading practices, and the possible existence of a threshold level for reading frequency are discussed.
Early phonological and lexical development and otitis media: a diary study
Authors: Donahue Mavis L. 
Published: September 2008

ABSTRACTThis diary study describes early phonological and lexical development in a child with chronic otitis media with effusion. Equipped with the tools of a referential/analytic language-learner, the child solved the problem of reduced and fluctuating auditory input with phonological selection and avoidance strategies that capitalized on prosodie cues. This ‘tone-language’ approach resulted in a lexical inventory that would be categorized as an extreme expressive style. Having ‘boot-strapped’ her lexical learning, the child continued to rely on phonological constraints and selection strategies to fuel lexical and syntactic growth, i.e. cross-domain interactions leading to a vocabulary spurt and the onset of two-word utterances. These findings illustrate the need to consider interactions among performance, input and linguistic constraints in order to explain individual variation in language learning.
Vowel dominance in overregularizations
Authors: Stemberger Joseph Paul 
Published: September 2008

ABSTRACTWhen children produce regularizations likecomed, not all verbs are equally likely to be regularized. Several variables (e.g. lexical frequency) have been shown to be relevant, but not all the variability between verbs is understood. It is argued here that one predictor is which vowels are present in the base form vs. the past tense form. Using a notion of recessive vs. dominant vowel (where recessive vowels are more likely to be replaced by dominant vowels than vice versa) based on adult phonological processing, it is predicted that regularizations should be likely when the base vowel is dominant and unlikely when the past tense vowel is dominant. Data from 17 children reported in the literature, aged 1;6–5;6, show that this prediction is correct. Implications for the role of phonological variables in the processing of irregular past tense forms are discussed.
Early lexical development in Spanish-speaking infants and toddlers
Authors: Jackson-Maldonado Donna , Thal Donna , Marchman Virginia , Bates Elizabeth , Gutierrez-Clellen Vera 
Published: September 2008

ABSTRACTThis paper describes the early lexical development of a group of 328 normal Spanish-speaking children aged 0;8 to 2;7. First the development and structure of a new parent report instrument,Inventario del Desarollo de Habilidades Communcativasis described. Then five studies carried out with the instrument are presented. In the first study vocabulary development of Spanish-speaking infants and toddlers is compared to that of English-speaking infants and toddlers. The English data were gathered using a comparable parental report, theMacArthur Communicative Development Inventories. In the second study the general characteristics of Spanish language acquisition, and the effects of various demographic factors on that process, are examined. Study 3 examines the differential effects of three methods of collecting the data (mail-in, personal interview, and clinic waiting room administration). Studies 4 and 5 document the reliability and validity of the instrument. Results show that the trajectories of development are very similar for Spanish-and English-speaking children in this age range, that children from varying social groups develop similarly, and that mail-in and personal interview administration techniques produce comparable results. Inventories administered in a medical clinic waiting room, on the otherhand, produced lower estimates of toddler vocabulary than the other two models.
