In our study, association-level talk in general may have been related to deeper processing of words learned and thereby growth in receptive vocabulary. In the end, with regard to duration, more time spent on vocabulary-related association talk (e.g., What is the difference between frozen water and liquid?) was found to be related to growth in children’s general receptive vocabulary. In addition,increased time spent in comprehension-related association talk(e.g., Can you drink something that is frozen? Why or why not?) was related to greater gains in generalized receptive vocabulary.
