Abstract:

The goal of this dissertation is to predict variation in Dutch
children’s vocabulary skills using data from the large-scale,
longitudinal YOUth cohort study. We take a dyadic approach to study
the effects of verbal, nonverbal, and multimodal behaviours during
caregiver-infant interactions on children’s vocabulary outcomes. This
dissertation consists of four empirical articles. Three key findings
emerged.

First, while there is a large interest in the annotation of
infant-directed speech, the accuracy of automatic speech recognition
tools on this speech register has remained largely unexplored. We show
that researchers can successfully use automated tools to facilitate
the labour-intensive manual annotation process. Second, we show that
key demographic factors explaining variation in children’s vocabulary
outcomes, such as maternal education, are age-specific and
task-specific. This highlights the importance of examining multiple
vocabulary outcomes across children’s development when studying
influences on variation. Third, while there is robust evidence that
infants’ gestures and vocalisations on the one hand, and caregivers’
contingent responses on the other hand, influence children’s
vocabulary outcomes, we show that dyadic and multimodal combinations
of these behaviours are stronger predictors. The findings show that
caregivers’ multimodal responses to infants’ gestures could play a
unique role in children’s expressive vocabulary development.

In research on children’s vocabulary development, we aim to describe
how infants gather sufficient information from the language input that
allows them to learn words. Studying the dyadic and multimodal nature
of early caregiver-infant interactions creates a more complete picture
of children’s learning environments which brings us closer to solving
this puzzle.
