The Role of Onomatopoeia in Children's Early Language Development, 2017-2018

Data and analysis from two studies investigating the role of onomatopoeia in children's vocabulary development. The corpus study uses data from the Language Development Corpus (University of Chigcago) to investigate the prevalence of onomatopoeia in child-directed language and children's productions. Here, analysis files are given as well as reliability data for lemmas classed as lexicalised onomatopoeia. Full data from the corpus is not available for publication here. The word learning study investigates the effect of onomatopoeia on novel word learning in 2-3 year old English-speaking children, in both concurrent and displaced learning contexts. Data is provided from 2 initial norming studies, to select stimuli for the experiment, and from the main experiment. Analysis at both stages is detailed in corresponding jupyter notebooks.
