    "title": "Why does Joint Attention Predict Vocabulary Acquisition? The Answer Depends  on What Coding Scheme you Use",
    "subtitle": null,
    "abstract": "Despite decades of study, we still know less than we would like \nabout the association between joint attention (JA) and language \nacquisition. This is partly because of disagreements on how to \noperationalise JA. In this study, we examine the impact of applying \ntwo different, influential JA operationalisation schemes to the same \ndataset of child-caregiver interactions, to determine which yields a \nbetter fit to children's later vocabulary size. Two coding schemes—\none defining JA in terms of gaze overlap and one in terms of social \naspects of shared attention—were applied to video-recordings of \ndyadic naturalistic toy-play interactions (N=45). We found that JA \nwas predictive of later production vocabulary when operationalised \nas shared focus (study 1), but also that its operationalisation as \nshared social awareness increased its predictive power (study 2). \nOur results emphasise the critical role of methodological choices in \nunderstanding how and why JA is associated with vocabulary size.",
