Abstract
This study examined sequential associations between pairs of caregiver talk and caregiver-child joint engagement categories. Sequential associations quantify the extent to which one event (such as a particular type of caregiver talk) follows another event (such as a particular type of joint engagement) in a pre-specified time window, while controlling for the chance occurrence of the sequence. Although unable to support strong conclusions about causality, the requirement of sequential analysis that key events occur within a close temporal sequence rules out alternative explanation for associations that summary-level correlations cannot. We applied sequential analysis to observational data on 98 caregiver-child dyads, fifty of which included a child with autism spectrum disorder (ASD). Groups were matched on mental age, and all were just beginning to develop spoken vocabulary. Sequential associations between supported joint engagement and caregiver follow-in utterances were stronger in ASD dyads as compared to dyads with typically developing children. Further, sequential associations between utterances related to the child's focus of attention followed by higher order supported joint engagement (HSJE) were stronger than between utterances that related to the caregiver's focus of attention and HSJE, across both groups. Finally, sequential associations between follow-in directives followed by HSJE were stronger than between follow-in comments followed by HSJE, again across both groups of children. Autism Res 2018, 11: 755-765.
