It takes two: Dynamics of conversation

One reason that face-to-face conversation may be difficult for many individuals on the autism spectrum is because multiple modalities of information (speech, eye contact, tone of voice) need to be integrated on the fly. We analysed all three of these modalities during natural conversations between school-age children and an adult partner. To look at patterns of eye gaze we had participants wear a head-mounted eye tracker.

We were also interested in how the topic of conversation might change these behaviours, so we compared conversations on neutral topics with those on either a child’s circumscribed interest (unusually intense interests that are common in autism),or their favourite hobby. One possibility is that speaking about a topic of strong interest may make children more engaged and reciprocal with their partner. On the other hand, these interests may be so consuming and perseverative in nature that they reduce reciprocal conversation.

Our findings indicated that, speaking about their circumscribed interest led children with ASD to be less adaptive to their partner verbally, but at the same time speaking about this highly practiced topic allowed for increased attention to their partner’s face. In more recent work on this topic, we have been examining how the timing of gaze to a partner’s face is coordinated with conversational turn exchanges.
