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.
