Computational Analysis of Backchannel Usage and Overlap Length in Autistic Children

Abstract

Backchanneling (e.g., right, okay, uhhuh) during a dialogue signals that a person is engaged and following along with what is being said. Although backchannels often overlap with other utterances, they are not interpreted as an attempt to take the floor when used successfully. Limited work has been done on investigating the frequency and overlap length of backchannels in the language of Autistic children. After controlling for age, sex, and IQ, we found that Autistic children used significantly less backchannels than their Typically Developing (TD) peers. Additionally, we found that Autistic children were less likely than TD children to produce a backchannel with a greater overlap length.
