Instrument adaptation for measuring early child language development across multilingual and sociocultural diverse settings
This article describes the adaptation of the MacArthur-Bates Communicative Development Inventory (CDI) for South Africa's 11 official spoken languages. The CDI is a parent-report tool that measures early language development from 8 to 30 months. We developed cross-linguistically comparable CDIs, representing two distinct language families, West Germanic and southern Bantu, using a common protocol. We describe our approach to item construction and…
Mean Length of Utterance
Mean Length of Utterance (MLU) has been widely used to measure children’s early language development in a variety of languages. This study investigates the utility of MLU to measure language development in four agglutinative and morphologically complex Southern Bantu languages. Using a variant of MLU, MLU3, based on the three longest sentences children produced, we analysed the utterances of 448 toddlers (16-32 months) collected using the MacArth…
A Crosslinguistic Study of Gesture and Lexical Development in South African Infants
This study compares early gesture and lexical development in 1,199 infants (0;8–1;6) across South Africa’s 11 official spoken languages using the MacArthur-Bates Communicative Development Inventory: Words and Gestures. We examined the effect of age, sex, ecological (urban-rural) setting, and maternal level of education (MLE) on early language development. Age was a significant predictor of gesture, comprehension, and production. There was no evid…
The development of speech and gesture in Sesotho narratives
Studies show that speech and gesture develop together with age, and the nature of gestures changes with increasing cognitive and discursive abilities. While there are common developmental trends, cultural differences may also impact development. We examined gesture development in narratives of Sesotho speaking children aged 5 to 6 years ( n = 12), 9 to 10 years ( n = 12) and adults ( n = 12), who watched a wordless cartoon and narrated the story …
