This study presents the validation analysis of the European Portuguese version of the MacArthur-Bates Communicative Development Inventory III (CDI-III-PT). The CDI-III-PT is a parental report measure allowing researchers to assess expressive vocabulary and the syntactic abilities of children aged 2;6–4;0. In this study, we present a version comprising a lexical subscale which follows the Swedish adaptation and an original syntactic subscale allowing us to include language-specific structures. The reports of 739 children were collected; in addition, a standardized measure of language was also administered to a sub-sample of these children and the reports of preschool teachers were collected for another sub-sample. The results indicate a high internal consistency of the lexical and syntactic subscales. As for sociodemographic variables often found to be predictors of language development, as measured by this type of instrument, the results indicate that age and maternal education are significant predictors of the scores, and that first-born children attain higher scores in vocabulary than later born children, but no significant gender differences were found. The scores of the CDI-III-PT are positively correlated with the ones obtained in the standardized language measure, thus supporting their validity. A high agreement between the reports of parents and teachers was also found. These findings indicate that the CDI-III-PT has adequate psychometric properties and that it can be a useful tool for research and clinical practice. The age-based norms that are now provided can be used to evaluate whether a child is performing poorly compared to their peers.

Purpose We examined receptive verb knowledge in 22- to 24-month-old toddlers with a dynamic video eye-tracking test. The primary goal of the study was to examine the utility of eye-gaze measures that are commonly used to study noun knowledge for studying verb knowledge. Method Forty typically developing toddlers participated. They viewed 2 videos side by side (e.g., girl clapping, same girl stretching) and were asked to find one of them (e.g., “Where is she clapping?”). Their eye-gaze, recorded by a Tobii T60XL eye-tracking system, was analyzed as a measure of their knowledge of the verb meanings. Noun trials were included as controls. We examined correlations between eye-gaze measures and score on the MacArthur–Bates Communicative Development Inventories (CDI; Fenson et al., 1994), a standard parent report measure of expressive vocabulary to see how well various eye-gaze measures predicted CDI score. Results A common measure of knowledge—a 15% increase in looking time to the target video from a baseline phase to the test phase—did correlate with CDI score but operationalized differently for verbs than for nouns. A 2nd common measure, latency of 1st look to the target, correlated with CDI score for nouns, as in previous work, but did not for verbs. A 3rd measure, fixation density, correlated for both nouns and verbs, although the correlation went in different directions. Conclusions The dynamic nature of videos depicting verb knowledge results in differences in eye-gaze as compared to static images depicting nouns. An eye-tracking assessment of verb knowledge is worthwhile to develop. However, the particular dependent measures used may be different than those used for static images and nouns.

Pointing Gesture

Abstract There is evidence of a strong association between the pointing gesture and early vocabulary acquisition. This study examined the extent to which this association is moderated by the communicative function of children’s pointing. A total of 35 children participated in the study. Their use of the pointing gesture and their expressive vocabulary were assessed at 13 and 18 months using the Early Social Communication Scales and the MacArthur-Bates Communicative Development Inventory, respectively. The results of multiple linear regression analyses indicated that variations in the frequency of declarative pointing at 13 months significantly contributed to variations in vocabulary size at both 13 and 18 months, independently of variations in maternal education. In contrast, variations in the frequency of imperative pointing did not concurrently or longitudinally correlate with children’s vocabulary sizes. These results suggest that the relation between pointing and early vocabulary acquisition is moderated by the communicative function of the pointing gesture.

This article reports on data obtained through the Quebec-French adaptation of the MacArthur–Bates Communicative Development Inventories – Words and Sentences ( N = 826). Results from parent questionnaires show a steady increase in expressive vocabulary and the use of morphology and syntax with age, as well as links between the three components. Strong correlations between parent reports and sample analysis confirm the concurrent validity of the parental reports.

Good Agreement

<b><i>Introduction:</i></b> The short forms of MacArthur-Bates Communicative Development Inventories (MB-CDI) are widely used for assessing communicative and linguistic development in infants and toddlers. Italian norms for the Words and Gestures (WG) and Words and Sentences (WS) short forms overlap between 18 and 24 months. <b><i>Objective:</i></b> To evaluate the agreement between these two forms. <b><i>Methods:</i></b> Parents of 104 children aged 18–24 months filled in both questionnaires. <b><i>Results:</i></b> The two questionnaires showed high agreement in measuring expressive vocabulary size and the percentile of lexical production and good agreement in identifying children at-risk for language delay (75% of the cases were accurately identified). Both short forms include a list of 100 words and a set of questions investigating potential risk factors for communication and language disorders. Ten children with an expressive vocabulary &#x3c;10th percentile were compared to 10 with typical language development. Scores for children &#x3c;10th percentile were significantly lower than their peers, in addition to scores of lexical comprehension, gesture-word, and 2-word combinations, and phonological accuracy, imitation of new words, and decontextualized use of language. <b><i>Conclusions:</i></b> Short forms of the Italian MB-CDI can be used interchangeably for evaluating lexical production, but each one offers different quantitative and qualitative information on the behaviours related to language acquisition.

Abstract A critical question in the study of language development is to understand lexical and syntactic acquisition, which play different roles in speech to the extent it would be natural to surmise they are acquired differently. As measured through the comprehension and production of closed-class words, syntactic ability emerges at roughly the 400-word mark. However, a significant proportion of the developmental work uses a coarse combination of function and content words on the MacArthur-Bates Communicative Development Inventory (MB-CDI). Using the MB-CDI Wordbank database, we implemented a factor analytic approach to distinguish between lexical and syntactic development from the Words and Sentences (WS) form that involves both function words and the explicit categorizations. Although the Words and Gestures (WG) form did not share the factor structure, common WG/WS elements recapitulate the expected age-related changes. This parsing of the MB-CDI may prove simple, yet fruitful in subsequent investigation.

Fitting Model

Expressive vocabulary data gathered during a systematic diary study of one male child's early language development are compared to data that would have resulted from longitudinal administration of the MacArthur Communicative Development Inventories spoken vocabulary checklist (CDI). Comparisons are made for (1) the number of words at monthly intervals (9;10.15 to 2;0.15), (2) proportion of words by lexical class (i.e. noun, predicate, closed class, ‘other’), (3) growth curves. The CDI underestimates the number of words in the diary study, with the underestimation increasing as vocabulary size increases. The proportion of diary study words appearing on the CDI differed as a function of lexical class. Finally, despite the differences in vocabulary size, logistic curves proved to be the best fitting model to characterize vocabulary development as measured by both the diary study and the CDI. Implications for the longitudinal use of the CDI 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.

The Impact

Parental reports are a widely-used source of information about infants’ and toddlers’ communicative skills, but parent-report instruments valid for children older than 30 months are less known. This study explored individual variability in children’s communicative skills at the age of 3;0 via parental reports using the Estonian (E) CDI-III. The validity of ECDI-III was established through correlations with another parent-report instrument (ECDI-II) and a standardized examiner-administered language assessment (New Reynell Developmental Language Scales; NRDLS). A hundred Estonian-speaking children ( M age = 35.77 months, age range from 34 to 39 months; 20 of them with reported language difficulties) participated in the study. Relations between different communicative skills and the impact of such factors as the child’s gender, maternal and paternal education, reported language difficulties, the number of siblings, and day care attendance on variability in vocabulary size were also considered. The results showed that the ECDI-III components were moderately to strongly associated with each other, with the ECDI-II and NRDLS. Children with reported language difficulties scored lower on all language measures, except for orthographic awareness. Girls, children of more educated mothers, children with older siblings, and those who had attended day care for more months obtained higher vocabulary scores.

Background: Vocabulary skills in infants with cleft lip and/or palate (CL/P) are related to various factors. They remain underexplored among Mandarin-speaking infants with CL/P. This study identified receptive and expressive vocabulary skills among Mandarin-speaking infants with unrepaired CL/P prior to cleft palate surgery and their associated factors. Methods: This is a cross-sectional study involving patients at the Cleft Lip and Palate Center of the Stomatological Hospital of Xi’an Jiaotong University between July 2017 and December 2018. The Putonghua Communicative Development Inventories-Short Form (PCDI-SF) was used to assess early vocabulary skills. Results: A total of 134 children aged 9–16 months prior to cleft palate surgery were included in the study. The prevalences of delays in receptive and expressive vocabulary skills were 72.39% (95% CI: 64.00–79.76%) and 85.07% (95% CI: 77.89–90.64%), respectively. Multiple logistic regression identified that children aged 11–13 months (OR = 6.46, 95% CI: 1.76–23.76) and 14–16 months (OR = 24.32, 95% CI: 3.86–153.05), and those with hard/soft cleft palate and soft cleft palate (HSCP/SCP) (OR = 5.63, 95% CI: 1.02–31.01) were more likely to be delayed in receptive vocabulary skills. Conclusions: Delays in vocabulary skills were common among Mandarin-speaking CL/P infants, and age was positively associated with impaired and lagging vocabulary skills. The findings suggest the necessity and importance of early and effective identification of CL/P, and early intervention programs and effective treatment are recommended for Chinese CL/P infants.
