Hearing is a complex ability that extends beyond the peripheral auditory system. A speech in noise/competition test is a valuable measure to include in the test battery when attempting to assess an individual’s “hearing”. The present study compared syllable vs. word scoring of the Greek Speech-in-Babble (SinB) test with 22 native Greek speaking children (6–12-year-olds) diagnosed with auditory processing disorder (APD) and 33 native Greek speaking typically developing children (6–12-year-olds). A three-factor analysis of variance revealed greater discriminative ability for syllable scoring than word scoring, with significant interactions between group and scoring. Two-way analysis of variance revealed SinB word-based measures (SNR50%) were larger (poorer performance) than syllable-based measures for both groups of children. Cohen’s d values were larger for syllable-based mean scores compared to word-based mean scores between groups for both ears. These findings indicate that the typ...

Passive electrophysiological protocols, such as the middle latency response and speech auditory brainstem response, are often advocated in the objective assessment of central auditory processing disorder (CAPD). However, few established electrophysiological protocols exist for CAPD assessment that have patients participate in active tasks which more closely approximate real-world listening. To this end, the present study used a discrimination task (i.e., oddball paradigm) to measure an enhancement of the auditory late response (N1-P2) that occurs when participants direct their auditory attention toward speech arising from an unexpected spatial location.To establish whether N1-P2 is enhanced when auditory attention is directed toward an unexpected location during a two-word discrimination task. In addition, it was also investigated whether any enhancements in this response were contingent on the stimulus being counted as part of the oddball paradigm.Prospective study with a repeated ...

Background: The known link between auditory perception and cognition is often overlooked when testing for cognition. Purpose: To evaluate auditory perception in a group of older adults diagnosed with mild cognitive impairment (MCI). Research Design: A cross-sectional study of auditory perception. Study Sample: Adults with MCI and adults with no documented cognitive issues and matched hearing sensitivity and age. Data collection: Auditory perception was evaluated in both groups, assessing for hearing sensitivity, speech in babble (SinB), and temporal resolution. Results: Mann–Whitney test revealed significantly poorer scores for SinB and temporal resolution abilities of MCIs versus normal controls for both ears. The right-ear gap detection thresholds on the Gaps-In-Noise (GIN) Test clearly differentiated between the two groups (p < 0.001), with no overlap of values. The left ear results also differentiated the two groups (p < 0.01); however, there was a small degree of overlap ...

Pediatric central auditory processing disorder (CAPD) is frequently comorbid with other childhood disorders. However, few studies have examined the relationship between commonly used CAPD, language, and cognition tests within the same sample.The present study examined the relationship between diagnostic CAPD tests and “gold standard” measures of language and cognitive ability, the Clinical Evaluation of Language Fundamentals (CELF) and the Wechsler Intelligence Scale for Children (WISC).A retrospective study.Twenty-seven patients referred for CAPD testing who scored average or better on the CELF and low average or better on the WISC were initially included. Seven children who scored below the CELF and/or WISC inclusion criteria were then added to the dataset for a second analysis, yielding a sample size of 34.Participants were administered a CAPD battery that included at least the following three CAPD tests: Frequency Patterns (FP), Dichotic Digits (DD), and Competing Sentences (CS)...

Diagnostic batteries to assess the integrity of the central auditory nervous system (CANS) include behavioral (i.e., psychophysical) tests, electrophysiologic procedures, and to some degree, electroacoustic procedures. In this chapter, we focus on behavioral tests used to identify lesions (including diffuse lesions), abnormalities, or dysfunction of the CANS, as well as identify associated functional deficits (e.g., listening in noise deficits). Following a brief review of several tests considered more peripheral in their application (e.g., pure-tone thresholds, otoacoustic emissions, acoustic reflex), we provide some historic context and a review of tests currently in use which are sensitized by design to measure central auditory function, as well as others which have not been adopted clinically and new tests and procedures which hold promise for clinical diagnosis. Tests reviewed include those of dichotic listening, temporal processing (e.g., temporal resolution and temporal patterning), binaural interaction (e.g., masking level differences), monaural low-redundancy measures (e.g., speech in noise or competition, filtered speech, time-compressed speech), and new paradigms which measure auditory evoked potentials in response to test stimuli typically used in behavioral tests.

This study was conducted to examine the auditory masking effects of classes of linguistic strings varying in syntactic and semantic constraints upon word discrimination abilities of children. Twelve fourth grade (age 9), normal hearing, native speakers of English served as subjects. Three half-lists of the Central Institute for the Deaf W-22 word lists were presented consecutively with one of three competing linguistic messages. Discrimination scores served as measures. A treatment-by-subject analysis of variance and t-tests for independent samples were used in the analysis of the data. No significant differences in word discrimination as a function of linguistic masker were found. Comparisons between the data obtained with the children of the present study and that of adult subjects of a similar investigation (Percept. Mot. Skills 41, 578-593, 1975) indicated no significant difference in mean discrimination scores under the grammatical and semantically anomalous conditions; however, significance was found for the ungrammatical masker. Selective listening and language processing were used in the discussion of the findings

Central auditory processing disorder (CAPD) and attention deficit hyperactivity disorder (ADHD) present overlapping symptomatology. Attention and listening problems, maladaptive behavior, distractibility, instruction-following difficulty, and increased time required to complete tasks appear on checklists purportedly characterizing behaviors exhibited by individuals with CAPD and ADHD. The present study compared audiologists&#39; and pediatricians&#39; rankings of 41 behavioral symptoms associated with ADHD and CAPD. Audiologists ranked the degree to which each item pertained to individuals with CAPD and pediatricians ranked the same items as related to ADHD. Item analysis revealed that only two of the most frequently cited behaviors were judged as characteristic of both disorders (i.e., inattention and distractibility). The majority of frequently cited behaviors were not seen as common to ADHD and CAPD.

Children diagnosed with attention deficit hyperactivity disorder (ADHD) frequently present difficulties performing tasks that challenge the central auditory nervous system. The relationship between ADHD and central auditory processing disorder (CAPD) is examined from the perspectives of cognitive neuroscience, audiology, and neuropsychology. The accumulating evidence provides a basis for the overlapping clinical profiles yet differentiates CAPD and ADHD as clinically distinct entities. Common and distinctive management strategies are outlined.

An educational hearing conservation (HCP) program was designed and presented to 45 normal hearing third- and fourth-grade children enrolled in regular education programs. Questionnaires assessing knowledge of hearing, noise-induced hearing loss, and hearing conservation practices were administered prior to and following a HCP which consisted of a lecture, film, hearing screening demonstration, question and answer and discovery learning periods, and distribution of earplugs and a handout. Most children reported that they did not participate in noisy activities; however, of those who did participate an average of only 5.5% (2.5) reported use of ear protection. Knowledge about noise and noise-induced hearing loss increased an average of 23% following the HCP and 91.1% reported that they "learned something" from the HCP. Post-HCP responses revealed that 96.7% of the children intended to use ear protection when engaged in the depicted noisy activities. Although students indicat...

Auditory processing disorder (APD) and attention-deficit hyperactivity disorder (ADHD) present overlapping symptomatology. Previous research has demonstrated that professionals use different behavioral descriptors to characterize APD and ADHD combined and predominantly hyperactive-impulsive subtypes, which present with hyperactivity, impulsivity, and inattention. The present study extends this research by comparing audiologists' and pediatricians' rankings of 58 behavioral symptoms associated with APD and ADHD predominantly inattentive (PI) subtype, the ADHD subtype that presents without hyperactivity and impulsivity. Audiologists ranked the degree to which each symptom pertained to individuals with APD, and pediatricians ranked the same symptom as it relates to ADHD-PI. Item analysis revealed that respondents identified a reasonably exclusive set of behaviors characterizing APD and ADHD-PI. None of the four behaviors ranked 2 SD above the grand means (i.e., inattention, aca...

The purpose of the present investigation was to establish developmental norms for work identification in quiet and in white noise in a normally hearing pediatric population. A second purpose of the study was to investigate the influence of minor variations in noise level for word identification performance. Twelve children from each of four age groups (mean age = 7.8, 9.0, 11.2, and 13.1 years) and 12 college students participated in Experiment I. NU-6 half-lists were presented in quiet and in noise (S/N = 0). Eleven college students, 7 ten-year-olds ( mean = 10.0 years) for 5 twelve-year-olds (mean = 12.0 years) served as subjects for Experiment 2. These subjects listened to NU-6 words in quiet in two noise conditions (S/N = 0 and S/N = +2). A factorial analysis of variance and Duncan&#39;s multiple range test revealed significant differences between subjects&#39; performance in quiet and in each noise condition. No age effect was observed. Results are discussed within the context of: 1) stimulus materials; 2) calibration tolerances; 3) equipment variables; 4) reinforcement; and 5) definitions of 0 dB signal-to-noise ratio.
