Vocabulary simplification for children: a special case of ‘motherese’?
Authors: Hayes Donald P. , Ahrens Margaret G. 
Published: February 2009

ABSTRACTA new corpus of spontaneous conversations between adults and children is examined for evidence that adults simplify their vocabulary choices when speaking with young children. If these simplifications are found to be age-dependent, then they would broaden the pattern of simplifications characteristic of ‘motherese’ to include lexical choice as well. For the age-range newborns to 12 years, the results are both consistent with and contrary to the attested set of grammatical simplifications. In this corpus, MLU and TTR are strongly age-dependent, but adults do not choose their words from the 10,000 most common word-types in English in an age-dependent manner. Rather, the additional types for school-aged children come from the same part of the vocabulary and share the same-shaped distributions as in adult speech with preschool children and infants. This absence of an age-dependent accommodation in word choice has implications for models of child lexical acquisition which assume adult language accommodation.
Children's production of commissive speech acts
Authors: Astington Janet W. 
Published: February 2009

ABSTRACTThis study determined at what age and in what form children (aged 4;5 to 11;11) produce speech acts which commit them to some future action, by having them speak a doll's part in dialogues with the experimenter, who spoke for another doll. All children produced directive speech acts, indicating that the task was not too difficult for them, but only the commissive speech acts were analysed in detail. A majority of children at all ages produced at least one commissive speech act, but only the older children used the explicit performative verb promise to reassure the hearer of their commitment.
The acquisition of the meanings of modality in children aged eight and twelve
Authors: Coates Jennifer 
Published: February 2009

ABSTRACTLittle is known about children's acquisition of modality. It seems clear that at the age of five, when they are said to be linguistically competent, children have not mastered the adult system of modal meaning. This paper describes research which tests children's understanding of modal meaning at the ages of eight and twelve. The results of these tests are compared with the results of the same test on adult informants. The research uses the card-sorting method devised by Miller (1971) to investigate semantic similarities and dissimilarities; cluster analysis of the data reveals the underlying patterns. My tests revealed that eight-year-old children have only a rudimentary system of modal meaning, and even by the age of twelve a child's system will not be isomorphic with the adult system.
Attribute saliency and metaphor interpretation in school-age children
Authors: Evans Mary Ann , Gamble Dianna Lynn 
Published: February 2009

ABSTRACTThe present investigation examined the relationship between attribute saliency and metaphor interpretation in school children. Ortony's theory that metaphors entail salience imbalance prompted the generation of two types of metaphors, PREDICATE-PROMOTING (PP) and PREDICATE-INTRODUCING (PI) metaphors. An adult sample was used to select metaphors of each type which were then presented to 24 children in each of grades three, five, and seven (mean ages 8; 5, 10; 6 and 12; 8). The children were asked to generate attribute lists for TOPIC and VEHICLE terms and, six weeks later, to verbally explain metaphors containing those terms. Older children correctly interpreted more metaphors than younger children, and at each grade level no difference was observed between the number of correct interpretations of PP and PI metaphors. In addition, at all grade levels the incorrect ground of each child's interpretation errors most often had been listed in his/her attribute lists. This suggests that attribute saliency for the individual perceiving the metaphor plays a key role in the interpretation process.
Quality of adult vocalizations affects the quality of infant vocalizations
Authors: Bloom Kathleen 
Published: February 2009

ABSTRACTThe purpose of the present study was to determine whether the VERBAL component of babytalk affected the vocal quality of infants. Two groups of 20 0;3 infants experienced either conversational turn taking or random responsiveness of an adult. Adult responsiveness consisted of a smile, light touch to the abdomen, and a NONVERBAL ‘tsk, tsk, tsk’ sound (instead of speech). All infant vocalizations were counted and then coded as ‘syllabic’ or ‘vocalic’ sounds. The results of the study demonstrated that TURN TAKING facilitated a speak-listen pattern of vocalizing by the infant, but in the absence of the VERBAL component of the adult's response, turn taking had no special facilitative effect on syllabic sounds. It was concluded that what adults say to 3-month-old infants influences what infants ‘say’ in return. Possible mechanisms underlying the infant's vocal response to verbal input were reviewed. It was suggested that the more mature sounds (syllabic) may proportionally increase as a result of the combined effects of turn-taking and verbal stimulation on the motor control of respiration and phonation.
Role of adult input in young children's category evolution: II an experimental study
Authors: Banigan Rae L. , Mervis Carolyn B. 
Published: February 2009

ABSTRACTYoung children's initial categories often are not identical to the adult category labelled by the same word. Eventually, children's categories must evolve to correspond to the adult standard. The purpose of this study was to consider the relative effectiveness of four input strategies in inducing the child to learn the adult-appropriate label and begin to form a new category. Fifty-six children aged 2;0 were taught new labels for objects that they included in categories labelled by different names. Comprehension and production post-tests were then administered. As expected, the most effective strategy involved labelling an object and providing both a physical demonstration and a verbal description of important attributes that made the object a member of the adult-appropriate category. The label plus physical demonstration strategy was next most effective. Neither the label plus verbal description strategy nor the label only strategy was effective for children of this age. Results also indicated that these 24 month olds did not yet honour the convention of mutual exclusivity of basic level categories.
The effect of previously learned words on the child's acquisition of words for similar referents
Authors: Tomasello Michael , Mannle Sara , Werdenschlag Lori 
Published: February 2009

ABSTRACTThe current study assessed the child's learning of an object label in two conditions: when its referent was highly similar and when its referent was highly dissimilar to the referent of a known child word. Twenty-two 2-year-old children were taught the name for an object. In a session several days subsequent, they were taught names for two new objects: one which was highly similar and one which was highly dissimilar to the referent of the word learned in the first session (two stimulus sets assured counterbalancing). In this second session, children produced the word with the similar referent more often than the word with the dissimilar referent. In third and fourth sessions (several days later), children continued to show better performance with the similar word in comprehension. These results were interpreted as evidence that young children find it easier to learn a new word when they are able to contrast its referent with that of a word they already know.
Development of forms and functions of interrogatives in children: a longitudinal study in Tamil
Authors: Vaidyanathan R. 
Published: February 2009

ABSTRACTThe development of the forms and functions of interrogatives in parent-child interaction in the early stages of language acquisition is discussed with illustrative examples from data relating to two Tamil-speaking children and their parents. The analysis of the data reveals that children first acquire and use intonation questions followed byenga‘where’,enna‘what’ andyaari‘who’. Yes/no questions using the interrogative marker-aaare acquired in the next stage when the children are able to use verb endings. Similarly question words that take case markers are acquired in the next stage. It is emphasized that interrogatives serve a multiplicity of communicative functions and are not restricted to the information-seeking role. Children, when they begin to use interrogatives, model their usage of them on the adult behaviour patterns to which they have been exposed, both in terms of form and function.
Private speech: evidence for second language learning strategies during the ‘silent’ period
Authors: Saville-Troike Muriel 
Published: February 2009

ABSTRACTThis study focuses on children who go through a ‘silent’ period early in the course of second language development, during which they largely cease verbal communication with speakers of the second language (English). Video recordings with radio microphones under natural conditions revealed that most of these children engaged in extensive private speech, which they were found to use for a variety of intrapersonal learning strategies, including (1) repetition of others' utterances, (2) recall and practice, (3) creation of new linguistic forms, (4) paradigmatic substitution and syntagmatic expansion, and (5) rehearsal for overt social performance. Quantity and quality of private speech was related not only to the children's level of cognitive development and the difficulty of the learning task (confirming previous research), but also to the children's social orientation and learning style, and to the domain of knowledge (language) that was being acquired.
New names from old words: related aspects of children's metaphors and word compounds
Authors: Elbers Loekie 
Published: February 2009

ABSTRACTLanguage has two mechanisms for creating new names from old words; combining morphemes and changing word meaning. Word compounds are clear cases of ‘combining’, metaphors of ‘changing’. A categorial framework for relating compounds and metaphors is presented and used in discussing aspects of their development. compelled and preferred compounds and metaphors are distinguished. Preferred compounds tend to serve the function of being conceptually precise, whereas preferred metaphors tend to serve ‘suggestive’ functions. Metaphoric compounds, which may integrate both functions, seem to be characteristic of middle childhood. Metaphors then may also acquire a language-learning function. It is suggested that the so-called literal stage, does not exist, but that the forms and functions of metaphor change in the course of development.
Cognitive and linguistic factors in the development of word definitions
Authors: Benelli Beatrice , Arcuri Luciano , Marchesini Gianni 
Published: February 2009

ABSTRACTThree studies were carried out in order to account for development of word definitions. Study i was aimed at analysing the role of class inclusion skills and age (5– and 7–year-olds and adults) in production of definitions containing superordinate categorical terms. No differences were found between 7-year-olds who had passed a class inclusion task and those who had not passed it as regards number of definitions containing superordinates, while differences were found between younger and older children and between children and adults. Study 2 was aimed at obtaining some normative criteria on the ‘goodness’ of definitions provided in Study 1, by using adult judges. It was found that the best definitions are those which contain both categorical terms and specific information about the to-be-defined object. It was also found that adults may adjust their standard definitional criteria to the kind of interlocutor (i.e. a child or a Martian). Study 3 confirms that younger children's definitions fall far short of the adult informativeness and completeness criteria while, by the age of ten, such criteria are met. Overall results were interpreted as conforming to a progressive conventionalization of children's strategies for defining objects.
Phonological development of two-year-old monolingual Puerto Rican Spanish-speaking children
Authors: Anderson Raquel , Smith Bruce L. 
Published: February 2009

ABSTRACTPhonetic and phonological analyses were performed on spontaneous speech samples of six 2–year–old monolingual Puerto Rican Spanish-learning children. The analyses showed a number of patterns of sound usage similar to those found in English-learning children of the same age, as well as children from other linguistic backgrounds. These findings add support to the claim that certain universal patterns exist in phonological development. However, a number of patterns were also observed which seemed to be accounted for by the target language being acquired. Similarities and differences among the individual children are also discussed.
Learning to use prepositions: a case study
Authors: Tomasello Michael 
Published: February 2009

ABSTRACTThe current study documented one child's earliest use of prepositions during her second year of life. The spatial oppositions up-down, on-off, in—out and over—under were first to be learned. These words were all used initially in non-prepositional senses (mostly as holophrastic, verb-like requests for activities) prior to prepositional usage. They were seldom omitted or misused. The prepositions with, by, to, for, at and of were learned later. Four of these were used to express at least two distinct case relationships, and some case relationships (instrumental and dative) were indicated by more than one of these words. These later learned prepositions were not used by adults or learned by the child as holophrases, but rather they were acquired as distinct lexical items by means of analytic learning strategies that employed some form of ‘extraction’ from adult phrases. These words were omitted and misused much more often than the spatial oppositions. Differences in the acquisition pattern of these two groups of prepositions were attributed to linguistic rather than to cognitive factors.
Performance factors in subject-auxiliary inversion by children
Authors: Nakayama Mineharu 
Published: February 2009

ABSTRACTChildren's reported copying-without-deletion errors, like ‘Whose is that is?’, have often been interpreted as the result of a non-adult rule of subject–aux inversion. By contrast, this study presents a performance account of these errors and supports this account by investigating what factors impede children's performance. Using an elicitation task, 16 test sentences were evoked from 16 3- to 5-year-old children. In particular, errors appeared (1) when the subject NP contained a relative clause, (2) when the relative clause had an object gap, and (3) when the relative clause was long. Since errors occurred in response to some sentence types and not others, and the children who made copying-without-deletion errors produced at least four correct responses, these results were interpreted as support for the performance account.
Writing in four- to six-year-olds: representation of semantic and phonetic similarities and differences
Authors: Landsmann Liliana Tolchinsky , Levin Iris 
Published: February 2009

ABSTRACTWhen asked to write an utterance, nursery children and kindergartners often produce strings of unrelated characters. We analysed whether these invented writings reflect similarities and differences in the phonetic and semantic aspects of the utterance. One hundred and twenty Israeli children were asked to write pairs of nouns that share a syllable (e.g. pe ‘mouth’ and perach ‘flower’) and series of sentences that share either mainly nouns or mainly verbs. The older the children, the more their invented writing reflected common linguistic elements and length of utterance. Similarities and differences on the word level were represented at a younger age than those on the syllabic level. Nouns were represented in children's written productions earlier than verbs and adverbs. Invented writing was interpreted as a linguistic act, drawing on the semantic, syntactic and phonological levels of language.
Prosody and the development of comprehension
Authors: Cutler Anne , Swinney David A. 
Published: February 2009

ABSTRACTFour studies are reported in which young children's response time to detect word targets was measured. Children under about six years of age did not show the response time advantage for accented target words which adult listeners show. When semantic focus of the target word was manipulated independently of accent, children of about five years of age showed an adult-like response time advantage for focussed targets, but children younger than five did not. It is argued that the processing advantage for accented words reflects the semantic role of accent as an expression of sentence focus. Processing advantages for accented words depend on the prior development of representations of sentence semantic structure, including the concept of focus. The previous literature on the development of prosodic competence shows an apparent anomaly in that young children's productive skills appear to outstrip their receptive skills; however, this anomaly disappears if very young children's prosody is assumed to be produced without an underlying representation of the relationship between prosody and semantics.
Turn taking affects the quality of infant vocalizations
Authors: Bloom Kathleen , Russell Ann , Wassenberg Karen 
Published: February 2009

ABSTRACTTwo groups of 20 infants aged 0; 3 experienced either conversational turn taking or random responsiveness of an adult. All infant vocalizations were counted and then each was categorized as a speech-like (syllabic) sound or a nonspeech-like (vocalic) sound. The results of this experiment indicated that turn taking caused changes in the quality of infant vocal sounds. When the adult maintained a give-and-take pattern, the infant produced a higher ratio of syllabic/vocalic sounds. The effect of turn taking on infant vocalizations was discussed in terms of its possible adaptive value for adult responsiveness.
Sound-meaning correspondences in babbling
Authors: Blake Joanna , Fink Robert 
Published: February 2009

ABSTRACTThe hypothesis that prelinguistic vocalizations contain extensive and systematic sound-meaning correspondences was examined through an exhaustive analysis of the babbling of five infants in their second year. These infants were videotaped over a period of three to six months at home and at a day-care centre. Their babbled utterances were transcribed phonetically and categorized according to consonant-type and vowel-type. Contexts for each utterance were also categorized, primarily according to the infant's simultaneous action. A quantitative analysis of co-occurrences between phonetic and contextual categories determined that across infants between 14 and 40% of utterances recurred in particular contexts with a greater than expected frequency. These findings support Halliday's (1975a) notion that babbling is not entirely random but contains consistent sound-meaning relations that are not adult-modelled. They also extend the notions of continuity between prelinguistic and linguistic stages of development to the semantic domain.
Communicative functions of pitch range and pitch direction in infants
Authors: Marcos Haydée 
Published: February 2009

ABSTRACTThe communicative functions of pitch direction and pitch range during the second year were investigated. The research focusses on initial plus repeated requests, either for objects or for co-operation, which were contrasted against giving, showing and labelling. Infants aged 1; 2 to 1;10 were observed in interaction with their mothers in a semistructured situation. Vocalizations were coded separately for communicative function and for prosodic features. Results show that pitch range is consistently higher (1) for repeated requests than for initial requests for objects and (2) for initial requests for objects and for co-operation than for labelling. Giving and showing have an intermediate rank between requests and labelling. Trends in prosodic contours were observed in both requests and labelling: rising tones were more frequently associated with requests whereas falling tones appeared more often in conjunction with labelling.
Concept formation and its relation to word learning and use in the second year
Authors: Lucariello Joan 
Published: February 2009

ABSTRACTDevelopmental differences in object word learning and use were investigated. Two groups of infant speakers: Beginner (vocabularies under 50 words) and Advanced (vocabularies over 50 words), participated in a concept formation and word learning and generalization experiment. Results indicated that both speaker groups formed concepts of and learned words for the to-be-learned objects, and generalized these words. However, Advanced speakers learned more concepts and words, and engaged in broader generalization than Beginner speakers. The following variables did not account for these developmental differences: child age, object permanence development, maternal speech, child action on objects. These findings can be explained by developmental differences in both the number and kind of object concepts formed in the second year. Words were primarily acquired for object concepts by both speaker groups. However, Beginner speakers formed fewer concepts, thus having a less extensive conceptual base supporting word learning. This may account for their lower levels of vocabulary acquisition. Additionally, Beginner speakers appear to form prototype/exemplar-based object concepts, leading to limited word extension, while Advanced speakers form featurally based object concepts, leading to broader extension.
Acquisition strategies in a first and second language: are they the same?
Authors: Cain Jacquelin , Weber-Olsen Marcia , Smith Rosslyn 
Published: February 2009

ABSTRACTWill adults whose native language is English and children whose native language is Spanish follow the same strategies in acquiring the category of noun gender and its functions in Spanish? This investigation shows that there are significant differences in first- and second-language acquisition. Performance on five tasks eliciting responses containing gender agreement was measured for two groups. Results suggest that there is a developmental progression in acquisition of noun gender for both groups. Nevertheless, on tasks containing grammatical and/or semantic conflict, even the linguistically least-experienced adults reflected correct, adult-like strategies for Spanish gender agreement, whereas only the oldest children performed in this manner.
