“…While the current study used an adaptive procedure to estimate threshold, the same procedures could be used to evaluate percent correct performance at a fixed signal and/or masker level. Another possible modification is that the stimuli can be presented through other transducers, including the soundfield 13 22 .…”

“…After each trial, the observer selects the interval containing the signal based on the infant's behavior. The results reported by Browning et al 13 demonstrated that this procedure is both feasible and efficient for use with 7 to 9 month-old infants. The method for testing toddlers and preschoolers closely follows procedures for testing infants, with the caveat that children's responses to sound are shaped using methods common with CPA.…”

“…The method described here builds on the work of Browning et al 13 , which evaluated the feasibility and efficiency of estimating infant behavioral thresholds using a two-interval, forced-choice adaptation of the observer-based psychophysical procedure 14 . In this method, the signal is presented during one of two observation intervals.…”

Collecting reliable behavioral data from toddlers and preschoolers is challenging. As a result, there are significant gaps in our understanding of human auditory development for these age groups. This paper describes an observer-based procedure for measuring hearing sensitivity with a two-interval, two-alternative forced-choice paradigm. Young children are trained to perform a play-based, motor response (e.g., putting a block in a bucket) whenever they hear a target signal. An experimenter observes the child's behavior and makes a judgment about whether the signal was presented during the first or second observation interval; the experimenter is blinded to the true signal interval, so this judgment is based solely on the child's behavior. These procedures were used to test 2 to 4 year-olds (n = 33) with no known hearing problems. The signal was a 1,000 Hz warble tone presented in quiet, and the signal level was adjusted to estimate a threshold corresponding to 71%-correct detection. A valid threshold was obtained for 82% of children. These results indicate that the two-interval procedure is both feasible and reliable for use with toddlers and preschoolers. The two-interval, observer-based procedure described in this paper is a powerful tool for evaluating hearing in young children because it guards against response bias on the part of the experimenter.

“…Researchers of hearing in infants should consider working together to develop a set of uniform stimuli that have been acoustically and psychoacoustically well characterized that would be suitable for use in infant studies. For many years, developmental psychoacoustics has focused on designing rigorous procedures for assessing performance in infants and children in a way that allows for comparison to adult performance (e.g., Aslin, Pisoni, Hennessy, & Perey, 1981;Browning, Buss, & Leibold, 2014;Schneider & Trehub, 1992;Trehub, Schneider, Thorpe, & Judge, 1991;Werker & Lalonde, 1988;Werner, 1995). As the interest in understanding infants' auditory processing in complex sound environments increases, it is imperative that we apply the same effort to the characterization of the sounds we use.…”

“…In the 2IFC observer-based procedure, a signal is presented on each trial in one of two temporal intervals; the observer must decide which interval contained the signal. Browning, Buss, and Leibold (2014) evaluated the feasibility and efficiency of a 2IFC observer-based procedure using a 500-ms low-pass filtered broadband noise for 7-to 9-month-old infants with normal hearing. The signal was presented in one of two 500-ms temporal intervals, visually marked in real time, separated with a 300-ms interstimulus interval (ISI).…”

Purpose It can be challenging to collect reliable behavioral responses to sound from individuals with significant motor or developmental impairments, the most common types of comorbid disability found in children with hearing loss (e.g., Gallaudet Research Institute, 2011 ). The purpose of this study was to test the feasibility of using a 2-interval, forced-choice, observer-based method for individuals considered to be difficult-to-test using behavioral audiometric assessments. Method Participants were 5 children with motor and developmental impairments, ages 5–15 years ( M = 11.6, SD = 4.6). The functional abilities of all participants were greater than 2 SDs below the mean, as measured by the Vineland-II Parent Caregiver Rating Form. Participants listened to either a male talker saying the word “playground” or a 1000-Hz warble tone, presented via an insert earphone or a sound field speaker. An observer, blind to signal presentation, selected 1 of 2 temporal intervals, determining which contained the signal based only on participant behavior. Criterion was reached when the observer correctly identified the interval containing the signal for 8 of the last 10 trials. Results An 80%-correct criterion was met for all participants, suggesting feasibility for use in children with motor or developmental impairment. Two participants were tested using an adaptive tracking procedure; a reliable threshold estimate was obtained for both children. This method offers promise for children who have difficulty performing behavioral audiometric assessments currently in use clinically.
