We present a neural network model of referent identification in a visual world task. Inputs are visual representations of item pairs unfolding with sequences of phonemes identifying the target item. The model is trained to output the semantic representation of the target and to suppress the distractor. The training set uses a 200‐word lexicon typically known by toddlers. The phonological, visual,...
Recent work has investigated the origin of infant colour categories, showing pre‐linguistic infants categorise colour even in the absence of colour words. These infant categories are similar but not identical to adult categories, giving rise to an important question about how infant colour perception changes with the learning of colour words. Here we present two novel paradigms in which 12‐ and 19‐month‐old...
We compared vocabulary sizes in comprehension and production between bilingual toddlers growing up in the United Kingdom (UK) and age‐matched UK English monolinguals (12–36 months old) using parent‐report vocabulary questionnaires. We found that bilingual toddlers' vocabulary sizes in English were smaller than the vocabulary sizes of their monolingual peers. Notably, this vocabulary gap was not found...
