Parent reports of their children’s expressive vocabulary and word combinations were obtained for 102 21- to 27-month-old children who were exposed to Spanish and English on a regular basis. The data were collected using an adapted version of the Language Development Survey (Rescorla, 1989). Expressive vocabulary size increased with age, and the girls’ mean vocabulary was larger than the boys’ mean vocabulary. Means, medians, and ranges of expressive vocabulary size and percentage of children combining words are presented, and potential screening guidelines are discussed.

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.

Size Discrepancy

PurposeCorrelates of receptive–expressive vocabulary size discrepancies may provide insights into why language development in children with autism spectrum disorder (ASD) deviates from typical language development and ultimately improve intervention outcomes.MethodWe indexed receptive–expressive vocabulary size discrepancies of 65 initially preverbal children with ASD (20–48 months) to a comparison sample from the MacArthur–Bates Communicative Development Inventories Wordbank (Frank, Braginsky, Yurovsky, & Marchman, 2017) to quantify typicality. We then tested whether attention toward a speaker and oral motor performance predict typicality of the discrepancy 8 months later.ResultsAttention toward a speaker correlated positively with receptive–expressive vocabulary size discrepancy typicality. Imitative and nonimitative oral motor performance were not significant predictors of vocabulary size discrepancy typicality. Secondary analyses indicated that midpoint receptive vocabulary size mediated the association between initial attention toward a speaker and end point receptive–expressive vocabulary size discrepancy typicality.ConclusionsFindings support the hypothesis that variation in attention toward a speaker might partially explain receptive–expressive vocabulary size discrepancy magnitude in children with ASD. Results are consistent with an input-processing deficit explanation of language impairment in this clinical population. Future studies should test whether attention toward a speaker is malleable and causally related to receptive–expressive discrepancies in children with ASD.

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.

Significant Difference

Introduction: Expressive vocabulary plays a vital role in child language development, and its assessment can be one of the essential indicators to identify language developmental delay, especially in children with Down syndrome. We developed a list of expressive vocabulary and compared the size and class of expressive vocabularies between typically developing and Down syndrome children. Materials and Methods: Expressive vocabulary of 150 children was examined  in  this study. A total of 120 typically developing Farsi-speaking children (in four age Groups, with   a 6-month interval) and 30 children with Down syndrome (aged 24-48 months) participated in this study. The parents of the children filled out the form that included 636 words from different vocabulary classes. These classes were based on studies that investigated language development in Farsi-speaking children. Results: The expressive vocabulary size in Farsi-speaking children was significantly higher than in Down syndrome children (P≤0.001). There was no statistically significant difference between boys and girls regarding expressive vocabulary size in two Groups of children. The size of nouns in all age Groups is more than other classes, and the size of conjunctions in all age Groups is less than the other ones. A direct correlation was found between age and the size of expressive vocabulary. Conclusion: According to the study findings, the list of expressive vocabulary can detect delays in developing expressive vocabulary.

ABSTRACTThe present study examined early vocabulary development in fifty-nine French monolingual and fifty French–English bilingual infants (1;4–1;6). Vocabulary comprehension was assessed using both parental report (MacArthur-Bates Communicative Development Inventory; CDI) and the Computerized Comprehension Task (CCT). When assessing receptive vocabulary development using parental report, the bilinguals knew more words in their L1 versus their L2. However, young bilinguals were as accurate in L1 as they were in L2 on the CCT, and exhibited no difference in speed of word comprehension across languages. The proportion of translation equivalents in comprehension varied widely within this sample of young bilinguals and was linked to both measures of vocabulary size but not to speed of word retrieval or exposure to L2. Interestingly, the monolinguals outperformed the bilinguals with respect to accuracy but not reaction time in their L1 and L2. These results highlight the importance of using multiple measures to assess early vocabulary development.

This paper presents an adaptation of the MacArthur-Bates Communicative Development Inventories (short version) into three languages spoken in Southern Mozambique. The tool was adapted to study vocabulary development among children of 12 to 25 months of age in two communities: a rural, monolingual Changana speaking community and an urban bilingual Ronga and Portuguese speaking community. We present a norming study carried out with the adaptation, as well as a validation study. The norming study revealed various predictors for reported expressive and receptive vocabulary size. These predictors include age, socioeconomic status, reported health problems, caregiving practices, and location. The validation of the CDI among a small sample in both communities shows positive correlations between the reported expressive vocabulary scores and children’s recorded word production. We conclude that the adapted CDI is useful for research purposes and could be used as a template for adaptations into other languages from similar cultures.

Vocabulary growth from 2;0 to 3;0 was studied in 28 late talkers using expressive vocabulary inventories reported bimonthly on the Language Development Survey (LDS). Group milestones were 18 words at 2;0, 89 words at 2;6, and 195 words at 3;0. A sub-group of 11 children (Group 1) showed a rapid vocabulary spurt between 2;2 and 2;8, reached the 150–180 word mark by 2;6, and attained the LDS ceiling of about 300 words by 2;10. In contrast, the 17 children in Group 2 still had a mean vocabulary of fewer than 30 words at 2;6, had less of a vocabulary spurt when they did start acquiring words, and attained the 150–180 vocabulary mark at 3;0. All 3;0 language outcome measures were significantly predicted by LDS vocabulary size from 2;2 to 2;4.

This study investigated whether young children learning two languages simultaneously are inherently weaker language learners than their monolingual counterparts. Two questions were examined: (a) whether simultaneous language learning at an early age slows down the language learning process for both languages (bilingualism deficit hypothesis) and (b) whether young children use a unitary language system containing features of both languages, preventing them from separating the languages (unitary language system hypothesis). To test these hypotheses, vocabulary skills of 10 German-English bilingual toddlers were compared with those of monolingual German- and English-speaking peers around 24 months of age using Rescorla's (1989) Language Development Survey. This vocabulary checklist, based on parental report, was used in its original English and in a German translated version. Findings revealed that bilingual toddlers were not inferior in conceptual vocabulary size and verb diversity when words in both languages were pooled. Given that nearly half of the bilingual conceptual vocabulary (43%) was associated with lexical forms in both languages, it is inferred that language separation is possible at age 2. Findings from this study contribute to the growing body of evidence that early simultaneous acquisition of more that one language is not an inherent disadvantage for the child. These findings suggest further that some existing instruments may be useful for assessing the early vocabulary of German-English bilingual toddlers.
