Central Auditory Processing in Severely Language Delayed Children: Six Case Study Presentations

Description: Responses of six severely language delayed (SLD) children were obtained on three measures of central auditory processing and one measure of language proficiency. The results of these measures were compared to the results obtained from six normal-hearing children, matched in age and Performance IQ on the WISC-R. The 12 children were tested with the Pitch Pattern Sequence Test (PPST), the Dichotic Digit Tests (DDT), and the Pediatric Speech Intelligibility Test (PSI). Differences in the central auditory abilities as well as the history of each child were presented in .a case study format. The results of the history information demonstrated no unusual problems among these 12 subjects. Ten out of 12 subjects demonstrated abnormal results on at least one measure of the central auditory battery.

Monaural and Binaural Speech Reception Thresholds in Normal Children and Those at Risk for Central Auditory Processing Disorders

Description: Children with central auditory processing disorders (CAPD) have a normal pure-tone audiogram, however, they have difficulty understanding speech in the presence of background noise. The present study examined binaural hearing in normal children and those with possible CAPD. Each subject was administered the SCAN or SCAN-A, screening tests for CAPD, to determine whether they were at risk for CAPD. Participants were then subjected to several monaural and binaural speech tasks, in quiet and noise. Spondee words were utilized in each task, under headphone and soundfield conditions.

A Normative Study of the Pitch Pattern Sequence and Dichotic Digits Tests in Children Aged 6 through 12

Description: Responses of 122 children were obtained on two measures of central auditory processing to establish normative data. Children aged 6.5 through 12.5 years were tested for humming and tapping responses to the Pitch Pattern Sequence Test (PPST) and the two- and four-digit Dichotic Digit Tests (DDT). Children between ages 6.5 and 9.5 years showed progressively better scores on the tapping response of the PPST and on the four-digit DDT. Children above 9.5 years of age demonstrated adult-like responses on both tests. No differences were demonstrated in performance of children aged 6.5 through 12.5 years on the two-digit DDT or on the humming response of the PPST.

Differentiation of Central Auditory Processing Disorder and Attention-Deficit Hyperactivity Disorder in Children and Adolescents

Description: The purpose of this study was to determine whether or not children diagnosed with Attention-Deficit Hyperactivity Disorder (ADHD) or Central Auditory Processing Disorder (CAPD) can be distinguished from one another on the basis of both objective and subjective assessment of attention and behavior. First, children and adolescents diagnosed with ADHD, CAPD, and concomitant ADHD/CAPD were compared to participants with emotional problems on measures of attention/concentration, depression, anxiety, and parental reports of internalzing and externalizing behaviors. Overall, statistical analyses did not reveal significant differences between performances of children diagnosed with ADHD and those diagnosed with CAPD. However, clinical comparisons across groups of children diagnosed with ADHD, CAPD, comorbid ADHD/CAPD and Affective Disorders revealed condition-specific clinical profiles, thus providing some support for CAPD as a distinct clinical entity. Second, exploratory cluster analysis was performed to further investigate the relationship between ADHD and CAPD. This procedure lead to the identification of four distinct clusters. However, analyses of these clusters revealed no distinct pattern of performance for children diagnosed with either ADHD or CAPD. Rather, participants with these diagnoses were evenly distributed throughout the clusters. Additionally, no cluster clearly represented the expected clinical profile for a diagnosis of CAPD- namely, significant auditory attentional/processing problems in the absence of other attentional difficulties. Implications for the assessment and treatment of childhood attentional disorders are discussed and recommendations for future research provided.
