Using the Language ENvironment Analysis (LENA) System to Investigate Cultural Differences in Conversational Turn Count.

Purpose This study investigates how the variables of culture and hearing status might influence the amount of parent-child talk families engage in throughout an average day. Method Seventeen Vietnamese and 8 Canadian families of children with hearing loss and 17 Vietnamese and 13 Canadian families with typically hearing children between the ages of 18 and 48 months old participated in this cross-comparison design study. Each child wore a Language ENvironment Analysis system digital language processor for 3 days. An automated vocal analysis then calculated an average conversational turn count (CTC) for each participant as the variable of investigation. The CTCs for the 4 groups were compared using a Kruskal-Wallis test and a set of planned pairwise comparisons. Results The Canadian families participated in significantly more conversational turns than the Vietnamese families. No significant difference was found between the Vietnamese or the Canadian cohorts as a function of hearing status. Conclusions Culture, but not hearing status, influences CTCs as derived by the Language ENvironment Analysis system. Clinicians should consider how cultural communication practices might influence their suggestions for language stimulation.
