The Relationship Between Infants’ Production Experience and Their Processing of Speech

The early relationship between childrens emerging articulatory abilities and their capacity to process speech input was investigated, following recent studies with English-learning infants. Twenty-six monolingual Italian-learning infants were tested at 6 months (no consistent and stable use of consonants, or vocal motor schemes [VMS]) and at the age at which they displayed use of at least one VMS. Perceptual testing was based on lists of nonwords containing one of three categories of sounds each: produced by infant (own VMS), not yet produced but typical of that age (other VMS), or not typically produced by infants at that age (non-VMS). In addition, size of expressive lexicon at 12 months and 18 months was assessed using an Italian version of the MacArthur-Bates Communicative Development Inventory (CDI). The results confirmed a relation between infant preverbal production and attentional response to VMS and also between age at first VMS and 12-month vocabulary. Maternal input is shown not to be a specific determinant of individual infant production preferences. A comparison between the English and Italian experimental findings shows a stronger attentional response to VMS in isolated words as compared to sentences. These results confirm the existence of an interaction between perception and production that helps to shape the way that language develops.

From phonetics to phonology: the emergence of first words in Italian.

This study assesses the extent of phonetic continuity between babble and words in four Italian children followed longitudinally from 0.9 or 0.10 to 2.0--two with relatively rapid and two with slower lexical growth. Prelinguistic phonetic characteristics, including both (a) consistent use of specific consonants and (b) age of onset and extent of consonant variegation in babble, are found to predict rate of lexical advance and to relate to the form of the early words. In addition, each childs lexical profile is analyzed to test the hypothesis of non-linearity in phonological development. All of the children show the expected pattern of phonological advance: Relatively accurate first word production is followed by lexical expansion, characterized by a decrease in accuracy and an increase of similarity between word forms. We interpret such a profile as reflecting the emergence of word templates, a first step in phonological organization.

Babbling and first words in children with slow expressive development

This study examined early vocal production to assess whether it is possible to identify predictors of vocabulary development prior to the age point at which lexical delay is usually identified. Characteristics of babbling and first words in 12 Italian children with slow expressive development (late talkers; LT) were compared with those of 12 typically developing (TD) peers. Syllable structure and phonetic characteristics of babbling and first words produced by both groups of children at 20 months were analysed during mother‐child play sessions. Results indicated that phonetic complexity and number of consonantal types were lower in the LT group. The two groups also differed in their use of sound classes and their syllable structure. Overall, it can be said that LTs development is similar to (but slower than) TDs, as opposed to having an atypical pattern of phonological development.

Characteristics of Phonological Development as a Risk Factor for Language Development in Italian-Speaking Pre-Term Children: A Longitudinal Study.

This study analysed the early linguistic development of Italian pre-term children. Samples of spontaneous pre-linguistic and verbal production were recorded at 12 and 18 months of age from two groups of children: 24 pre-term children and 15 full-term children. The Italian version of the MacArthur-Bates Questionnaire was administered at 24 months of age. Comparisons between these two groups reveal differences in many aspects of phonetic and phonological development, such as consonantal inventory at 12 and 18 months of age and syllabic babbling complexity at 18 months of age. Results evidenced that birth weight was related with phonological skills exhibited at 18 months of age, and these skills in turn are related with vocabulary size at 24 months of age. Data are discussed within a theoretical framework that hypothesizes that early phonetic abilities have long-lasting effects on the process of language acquisition.

Parents' Child-Directed Communication and Child Language Development: A Longitudinal Study with Italian Toddlers.

The present study focuses on the characteristics of parental child-directed communication and its relationship with child language development. For this purpose, thirty-six toddlers (18 males and 18 females) and their parents were observed in a laboratory during triadic free play at ages 1 ; 3 and 1 ; 9. The characteristics of the maternal and paternal child-directed language (characteristics of communicative functions and lexicon as reported in psycholinguistic norms for Italian language) were coded during free play. Child language development was assessed during free play and at ages 2 ; 6 and 3 ; 0 using the Italian version of the MacArthur-Bates Communicative Development Inventory (2 ; 6) and the revised Peabody Picture Vocabulary Test (PPVT-R) (3 ; 0). Data analysis indicated differences between mothers and fathers in the quantitative characteristics of communicative functions and language, such as the mean length of utterances (MLU), and the number of tokens and types. Mothers also produced the more frequent nouns in the child lexicon. There emerged a relation between the characteristics of parental child-directed language and child language development.

Hospitalized children’s representations of their relationship with nurses and doctors:

This article reports an explorative study which aims to investigate hospitalized children’s views of their relationships with nurses and doctors. Twenty-seven school-aged children and adolescents from 6 to 15 years old in the paediatric haematology and oncology ward of an Italian hospital participated in the study. Each participant was asked to draw him or herself with a doctor or nurse from the ward while they were doing something. The drawings were analysed using Pictorial Assessment of Interpersonal Relationships (PAIR) and a qualitative analysis. The results showed that the participants viewed their relationships with health professionals positively, in particular with the nurses. This relationship was perceived as close, intimate, cohesive and without conflict. In some cases it became an emotional bond. Finally, this relationship helped the patients to cope with painful and uncomfortable medical procedures, which gradually became familiar and accepted. The clinical implications of this study are discussed.

The transition into ambient language: A longitudinal study of babbling and first word production of Italian children

The present study investigates the appearance of certain phonetic, phonological, and prosodic aspects of Italian in the early language of native speakers; a longitudinal analysis of babbling and word production in 11 Italian children ranging in age from 0;10 to 2;0 is reported. It focuses in particular on the syllabic frequency of babbling utterances and the distribution of consonant sounds in relation to their place of articulation in babbling and first words. It analyzes also the role of phonotactic characteristics and accentual patterns of word targets in production correctness and word shape constraints. Results show that the relationships with the frequency characteristics of the Italian lexicon become increasingly evident in language production from age 0;11 on. The data also provide substantiation for the role of phonotactic characteristics and accentual patterns in influencing correct word production. Finally, a continuity between babbling and words emerged from an analysis of individual differences. The discussion focuses on the role of ambient characteristics of language versus universal articulatory constraints in early phonological development.

Speaking about emotional events in hospital The role of health-care professionals in children emotional experiences

This paper presents a qualitative study aimed at exploring the role of health-care professionals in hospitalized children’s emotional experiences. A total of 27 children and adolescents from ages 6 to 15 years admitted to the Pediatric Hematology and Oncology ward of an Italian hospital participated in the study. Each participant was asked to talk about an emotional experience of happiness, anger, sadness and fear, felt in the presence of a doctor or nurse on the ward. The emotional tales were coded and analyzed qualitatively. The results showed that all the emotions considered were experienced when the staff was present, nurses in particular. Doctors and nurses played a role of active participants, encouraging children’s emotions, especially for happy events. More research is needed to clarify the role of the staff in supporting children to cope with negative emotions.

Spontaneous Gesture Production and Lexical Abilities in Children With Specific Language Impairment in a Naming Task

PURPOSE The purpose of the study was to investigate the role that cospeech gestures play in lexical production in preschool-age children with expressive specific language impairment (E-SLI). METHOD Fifteen preschoolers with E-SLI and 2 groups of typically developing (TD) children matched for chronological age (n = 15, CATD group) and for language abilities (n = 15, LATD group) completed a picture-naming task. The accuracy of the spoken answers (coded for types of correct and incorrect answers), the modality of expression (spoken and/or gestural), types of gestures, and semantic relationship between gestures and speech produced by children in the different groups were compared. RESULTS Children with SLI produced higher rates of phonological simplifications and unintelligible answers than CATD children, but lower rates of semantic errors than LATD children. They did not show a significant preference for spoken answers, as TD children did. Similarly to LATD children, they used gestures at higher rates than CATD, both deictic and representational, and both reinforcing the information conveyed in speech and adding correct information to co-occurring speech. CONCLUSIONS These findings support the hypotheses that children with SLI rely on gestures for scaffolding their speech and do not have a clear preference for the spoken modality, as TD children do, and have implications for educational and clinical practice.

The use of sophisticated words with children with specific language impairment during shared book reading

UNLABELLED In the context of the use of sophisticated (i.e., low-frequency) words with children with specific language impairment (SLI), the present study investigates the relationship between maternal interactive support for meaning and both conversational responsiveness and lexical development of children with SLI. Fifteen Italian-speaking children with SLI (age range: 3;4-5;6) and two groups of typically developing children--15 chronological age (CA)-matched (3;8-5;8) and 15 language age (LA)-matched (1;10-3;5)--were videotaped during shared book reading with their mothers. Maternal utterances which included or were related to a sophisticated word were coded on the basis of informativeness and scaffolding provided; child utterances were coded for complexity. In addition, childs lexical development was assessed three months later. Mothers of children with SLI produced a higher percentage of directly informative utterances with gestural scaffolding than did mothers of CA-matched children, and only in the SLI group this kind of utterances were significantly followed by childs extended utterances. Childs lexical development (production) was related to direct maternal informativeness in both the SLI- and CA-matched groups, and to gestural scaffolding only in the SLI group. On the whole, these findings suggest that mothers of children with SLI attune their language to their childrens linguistic limitations and that the gestural quality of the interactive scaffolding is related to these childrens conversational participation and their level of lexical progress. LEARNING OUTCOMES The reader will recognize the importance of maternal support for the meaning of low-frequency words in promoting the childs conversational responsiveness and lexical development, particularly with children with SLI. These children seem to benefit when provided with direct information accompanied by gestural scaffolding. These findings, if replicated with a larger group of participants, could help clinicians develop improved strategies for teaching parents.
