Abstract

BACKGROUND:

The recently developed Gaps-In-Noise (GIN) test has provided a new diagnostic tool for the detection of temporal resolution deficits. Previous reports indicate that the GIN is a relatively sensitive tool for the diagnosis of central auditory processing disorder ([C]APD) in adult populations.

PURPOSE:

The purpose of the present study was to determine the feasibility of the GIN test in the pediatric population.

RESEARCH DESIGN:

This was a prospective pseudorandomized investigation.

STUDY SAMPLE:

This investigation involved administration of the GIN to 72 participants divided into six groups of normal children ranging from 7 through 18 years of age.

DATA COLLECTION AND ANALYSIS:

The approximate GIN threshold (the shortest gap duration for which at least four of six gaps were correctly identified) served as the dependent variable. Results were analyzed using an ANOVA to examine between- and within-group differences.

RESULTS:

No statistically significant differences were seen in GIN thresholds among age groups. In addition, within group analysis yielded no statistically significant differences between ears within each age group. No developmental effect was seen in GIN thresholds between the ages of 7 and 18 years. Children as young as age 7 are able to complete the GIN with no significant difficulty and perform at levels commensurate with normal adults. The absence of ear differences suggests that temporal resolution as measured by the GIN is an auditory process that develops relatively early and symmetrically (i.e., no laterality or ear dominance effects).

CONCLUSIONS:

The GIN procedure appears to be a feasible measure of temporal resolution in both pediatric and adult populations.
