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.

Modality Specificity

Purpose: This article argues for the use of modality specificity as a unifying framework by which to conceptualize and diagnose central auditory processing disorder (CAPD). The intent is to generate dialogue and critical discussion in this area of study. Method: Research in the cognitive, behavioral, and neural sciences that relates to the concept of modality specificity was reviewed and synthesized. Results: Modality specificity has a long history as an organizing construct within a diverse collection of mainstream scientific disciplines. The principle of modality specificity was contrasted with the unimodal inclusive framework, which holds that auditory tests alone are sufficient to make the CAPD diagnosis. Evidence from a large body of data demonstrated that the unimodal framework was unable to delineate modality-specific processes from more generalized dysfunction; it lacked discriminant validity and resulted in an incomplete assessment. Consequently, any hypothetical model resulting from incomplete assessments or potential therapies that are based on indeterminate diagnoses are themselves questionable, and caution should be used in their application. Conclusions: Improving specificity of diagnosis is an imperative core issue to the area of CAPD. Without specificity, the concept has little explanatory power. Because of serious flaws in concept and design, the unimodal inclusive framework should be abandoned in favor of a more valid approach that uses modality specificity.

Целью исследования был сравнительный анализ жалоб и аудиологических показателей у пациентов сурдологического центра в зависимости от возраста. Представлены результаты обследования 300 первичных пациентов (случайная выборка), обратившихся к сурдологу-оториноларингологу в течение 1 мес. В группу молодых пациентов (19-44 года) вошли 40 человек; в группу среднего возраста (45- 59 лет) - 62 человека; в группу пожилых (60-74 года) - 100 человек; в группу старческого возраста (75-90 лет) - 98 человек. Обследование включало сбор жалоб и анамнеза, ЛОР-осмотр, тональную пороговую аудиометрию, импедансометрию, речевую аудиометрию в наушниках для выявления признаков центральных слуховых расстройств или в свободном звуковом поле для оценки эффективности слухопротезирования. Установлено, что для ранней диагностики тугоухости и профилактики возрастных сенсорнокогнитивных дисфункций целесообразно использовать не только результаты тональной пороговой аудиометрии, но и данные речевой аудиометрии, а также анализ субъективных жалоб. Результаты работы свидетельствуют о необходимости организации скрининга состояния слуха в рамках диспансеризации населения старше 60 лет. The aim of the study was a comparative analysis of complaints and audiological findings in patients of the audiological center depending on their age. The results of the examination of 300 fi rstly consulted patients (random sample) are presented. The group of young patients (19-44 years) included 40 people; middle age (45-59 years) - 62 people; elderly (60-74 years) - 100 people; senile age (75-90 years) - 98 people. The survey included the collection of complaints and anamnesis, ENT checkup, pure tone audiometry, impedancemetry, speech audiometry in headphones to detect the signs of Central Auditory Processing Disorder or in the free sound field to assess the effectiveness of hearing aids. It was found that for early diagnosis of hearing loss and prevention of age-related sensory-cognitive dysfunction, it is advisable to use not only the results of pure tone audiometry, but also the data of speech audiometry, as well as the analysis of subjective complaints. The results of the work indicate the need for hearing screening in the population over 60 years old.

Data Collection And Analysis

Background: Auditory gap detection is a measure of temporal acuity. The paradigm comes in two forms, distinguished by whether the sounds bounding the silent period are the same (within channel [WC]) or different (between channel [BC]). Purpose: The purpose of this study was to test normal children and children referred for auditory processing disorder (APD) assessment, with both gap detection paradigms. Research Design: Best gap durations (i.e., shortest reliably detected gaps) were measured in a two-interval, two-alternative forced-choice design embedded within a modified method of limits, for both WC and BC paradigms, with stimuli presented at 55 dB HL. Study Sample: Sixteen control children and 20 children referred for APD assessment participated in the study. Of the 20 referred children, 9 were diagnostically positive for APD (APD+), and 11 were negative (APD−). The mean age of children in all three groups was 10–11 yr. Data Collection and Analysis: Data collected were best gap durations for each paradigm, for each child. Group differences were assessed using Kruskal-Wallis analyses of variance. Results: WC best gap durations were very similar across the three participant groups. BC best gap durations varied significantly between listener groups, with the greatest difference being between controls and APD+ samples. Conclusions: BC best gap durations differed among the listener groups while WC ones did not. This suggests that the relative timing perceptual operations required by the BC task are more susceptible to the perceptual disturbances in APD than is the simple event detection required by the WC task.
