Communicative Gestures

Use of communicative gestures in a group of children with delayed onset of expressive oral vocabulary (late talkers) was compared with such use among normal-language-matched controls and age-matched controls. Analyses revealed that late talkers used significantly more communicative gestures and for a greater variety of communicative functions than did language-matched controls. However, a 1-year follow-up revealed that 4 of the late talkers remained delayed (truly delayed late talkers) and 6 caught up (late bloomers). Reanalyses of Year 1 data based on these follow-up outcomes demonstrated that only late bloomers used more communicative gestures than did language-matched controls. Truly delayed late talkers did not differ from language-matched controls either for number of gestures, type of gestures (symbolic vs. nonsymbolic), or number of different functions for which gestures were used. Late bloomers also used more communicative gestures than did age-matched controls, suggesting that they (the late bloomers) were using gestures to compensate for their small oral expressive vocabulary. Results are discussed in the context of early predictors of risk for language impairment and relationships between language and cognition.

Three Components

AbstractThis longitudinal study assessed three acoustic components of maternal infant-directed speech (IDS) – pitch, affect, and vowel hyperarticulation – in relation to infants’ age and their expressive vocabulary size. These three individual components were measured in IDS addressed to infants at 7, 9, 11, 15, and 19 months (N = 18). All three components were exaggerated at all ages in mothers’ IDS compared to their adult-directed speech. Importantly, the only significant predictor of infants’ expressive vocabulary size at 15 and 19 months was vowel hyperarticulation, but only at 9 months and beyond, not at 7 months, and not pitch or affect at any age. These results set apart vowel hyperarticulation in IDS to infants as the critical IDS component for vocabulary development. Thus IDS, specifically the degree of vowel hyperarticulation therein, is a vehicle by which parents can provide the most optimal speech quality for their infants’ linguistic and communicative development.

Preterm Children

The vocabulary size and composition of one group of full-term and three groups of low risk preterm children with different gestational ages (GA) were longitudinally compared at 10, 22 and 30 months of age. Expressive vocabulary development was assessed through the CDI. Cognitive development was also assessed at 22 months (Batelle Developmental Inventory), and data concerning biological and environmental characteristics of the children were also obtained. Growth curve analyses indicated that there were no significant differences in vocabulary size or percentage of word categories among GA groups. Regression analyses showed that word production and cognitive scores measured at 22 months were the main predictors of total vocabulary and word categories at 30 months. Gender, maternal education and GA did not contribute in a significant way to the variance of use of the vocabulary categories or vocabulary size. Therefore, GA does not seem to affect vocabulary development and composition when biomedical complications associated to prematurity are excluded.

Communicative Participation

This study explored participation- and impairment-based outcomes for 24 late-to-talk toddlers ( M age = 20.46 months, SD = 3.09, 62.5% male) whose parents participated in Target Word™, The Hanen Program® for Parents of Children who are Late Talkers in community clinics across Ontario. Parents completed the MacArthur–Bates Communicative Development Inventories (MBCDI), The Focus on the Outcomes of Communication Under Six (FOCUS-34), and a speech sound checklist: (1) prior to starting the program, (2) at the end of direct intervention, and (3) after a consolidation period. Speech-language pathologists classified children’s communicative function using the Communication Function Classification System (CFCS) at all assessment points and provided FOCUS scores from an initial assessment. No change was recorded in CFCS levels between initial assessment and start of the program, but many children moved to a more advanced level by the end of the program ( n = 12) or consolidation period ( n = 19). Significant changes in children’s communicative participation skills (FOCUS) were found between initial assessment and the start of the program, and during the 12-week direct intervention (75% made clinically meaningful change). Significant growth in expressive vocabulary and consonant inventory occurred during direct intervention. Correlations between change on impairment- and participation-based measures were not significant. The Target Word program appears to improve communicative function for late-to-talk preschoolers. Children also made gains in communicative participation skills, expressive vocabulary, and consonant inventory during the program, but further research is needed to determine the effectiveness of Target Word in these areas.

Time Period

Purpose This research explored whether sustained maternal responsivity (a parent–child interaction style characterized by warmth, nurturance, and stability as well as specific behaviors, such as contingent positive responses to child initiations) was a significant variable predicting vocabulary development of children with fragile X syndrome through age 9 years. Method Fifty-five mother–child dyads were followed longitudinally when children were between 2 and 10 years of age. Measures of maternal responsivity and child vocabulary were obtained at regular intervals starting at age 2.9 years. Sustained responsivity was indicated by the average responsivity measured over Observations 2–5. Responsivity at the 1st time period, autism symptoms, and cognitive development were used as control variables. Results After controlling for development and autism symptoms, the authors found significant effects for sustained responsivity on receptive vocabulary, expressive vocabulary, and the rate of different words children produced through age 9. Conclusions Maternal responsivity, which is typically a variable of interest during early childhood, continues to be a significant variable, predicting vocabulary development through the middle childhood period. Thus, responsivity is a potential target for language interventions through this age period.

ABSTRACTThis study investigated vocabulary size and vocabulary composition in Greek children aged 1 ; 6 to 2 ; 11 using a Greek adaptation of Rescorla's Language Development Survey (LDS; Rescorla, 1989). Participants were 273 toddlers coming from monolingual Greek-speaking families. Greek LDS data were compared with US LDS data obtained from the instrument's normative sample (Achenbach & Rescorla, 2000). Vocabulary size increased markedly with age, but Greek toddlers appeared to get off to a slower start in early word learning than US children. The correlation between percentage word use scores in Greek and US samples was moderate in size, indicating considerable overlap but some differences. Common nouns were the largest category among the fifty most frequent words in both samples. Numbers of adjectives and verbs were comparable across languages, but people and closed-class words were more numerous in the Greek sample. Finally, Greek late talkers showed similar patterns of vocabulary composition to those observed in typically developing Greek children.

Phonological Abilities

The purpose of this investigation is to determine whether a focused stimulation intervention focusing on lexical training has indirect, secondary effects on children's phonological abilities. Twenty-five toddlers with expressive vocabulary delays and their mothers were randomly assigned to intervention and control groups. The children were between 23 and 33 months of age at entry into the study and were at the single-word stage of language development. Parents of late talkers in the experimental group were trained to employ frequent, highly concentrated presentations of target words without requiring responses. Two measures of phonological diversity (i.e., syllable structure level and consonant inventory) and one measure of accuracy of production (i.e., percent consonants correct) were measured prior to and following intervention within the context of mother-child interactions. The toddlers who received intervention made treatment gains in two areas of phonological ability. They used a greater variety of complex syllable shapes and expanded their speech sound inventories to include more consonant sounds in both initial and final position. In contrast, there were no effects of language treatment on the accuracy of correct production when compared to the adult phonological system.
