A New CAPD Battery—Multiple Auditory Processing Assessment

Abstract

Based on recommendations by Musiek & Chermak (1994, American Journal of Audiology, 3, 23-27) and ASHA (1996, American Journal of Audiology, 5(2), 41-54), a battery of four commonly used tests was selected and recorded for use in assessing school children. These tests were labeled the Multiple Auditory Processing Assessment (MAPA) and then administered to an initial sample of 81 third grade children, along with the SCAN screening test for auditory processing disorders. Afterward, several exploratory factor analyses were performed on the findings, and comparisons were made between the results for the MAPA and SCAN. Four separate factors emerged from the four MAPA tests, which were linked closely to the components of central auditory processing disorders (CAPDs) defined by ASHA (1996, American Journal of Audiology, 5(2), 41-54). These factors were labeled monaural separation/closure (MSC), auditory pattern/temporal ordering, binaural integration, and binaural separation (BS). SCAN appears to measure two of these factors, MSC and BS. Use of MAPA is encouraging. Our findings suggest it may provide an appropriate multiple-test, CAPD battery for third grade children, and it meets at least some of the objectives described in the consensus document proposed by ASHA (1996, American Journal of Audiology, 5(2), 41-54).

Educators as Referrers for Central Auditory Processing Assessments

“…Literature is available describing the close association between CAPD and literacy and academic problems and CAPD and speech and language disorders (Bamiou, Musiek, & Luxon, 2001;Banai & Kraus, 2007;Domitz & Schow, 2000). Numerous theories have been hypothesized (although not yet proven) to explain the link between CAP, language and learning difficulties.…”

Auditive Verarbeitungs- und Wahrnehmungsstörungen (AVWS): Zusammenfassung und aktualisierter Überblick

“…Ein Goldstandard für die Diagnose einer AVWS ist international bislang nicht verfügbar [11][12][13][14][15] bzw. vermutlich auch nicht erreichbar [1,4,16].…”

“…Generell sprechen Werte, die 2 oder mehr Standardabweichungen in mehr als einem Test unterhalb der Werte der Referenzpopulation liegen, für eine AVWS. Würden weniger scharfe Diagnosekriterien angewandt, würde ein nicht unerheblicher Anteil von Kindern eines unauffälligen Kollektivs als Risikopopulation bezüg-lich einer AVWS eingeschätzt werden [12,20,25].…”

Application of Neural Network Modeling to Identify Auditory Processing Disorders in School-Age Children

“…Both of these measures are highly sensitive to lesions in the CANS [48,50,51] and performance of children with APD can be compared to age norms available for school-age children on both of these tests [10,52]. These tests were also selected because they can provide useful measures of auditory pattern recognition and temporal ordering [46,47]. Tables 3 and 4 show the performance of all subjects in behavioral tests.…”

“…The subtests in the SCAN screening battery for children included (a) Filtered Words (to evaluate auditory closure), (b) Auditory Figure-Ground (to evaluate speech in noise), and (c) Competing Words (to evaluate dichotic speech). Screening by these tests provides consideration of the following factors: (a) monaural separation/closure, (b) binaural integration, and (c) binaural separation [46,47]. The two auditory pattern perception tests used for clinical assessment of APD were (1) Pitch Patterns Test (PPT) [48] and (2) Duration Patterns Test (DPT) [49].…”
