Auditory Behavior of 2- to 4-year-old Children: Types of Behavior Observed and Inter-rater Reliability
Collecting reliable behavioral data from toddlers and preschoolers is challenging. As a result, our understanding of human auditory development for these age groups has significant gaps. In order to address this knowledge gap, it is critical to develop a reliable behavioral method for measuring auditory perception in toddlers and preschoolers that can be used in the laboratory. One method that appears to be promising is a recently developed testing method, in which a child’s behavior is judged by an experimenter (called an “observer”) using a two-interval, two-alternative testing paradigm (Bonino and Leibold, 2017). Children’s response to the stimulus is further shaped by training them to perform a conditioned play-based response to the sound. Preliminary data show that this method is feasible for testing the hearing abilities of 2- to 4-year-olds. However, one potential pitfall of this method is that the observer’s ability to judge a child’s behavior can influence the threshold obtained. In order to evaluate this concern, and the purpose of this project, testing sessions of 2- to 4-year-old children (n=20) were video recorded performing a tone detection in quiet task. Test session was then scored independently by two offline observers. Agreement of offline observers will be assessed trial-by-trial, as well as for signals that are above and below threshold (71%). The type of auditory behaviors demonstrated by children will also be coded. We will discuss the inter-rater reliability of this method and how that reliability is affected based on signal intensity level and the type of auditory behavior provided by the child. Pilot data from children who are developmentally delayed will also be shared.
