Purpose: In most cases, caregiver questionnaires are completed by mothers and seldom by fathers. Although parents tend to have moderate to high congruence, some studies suggest that differences between the mothers' and the fathers' answers can complicate diagnostic decision-making. The aim of this study was to determine mother-father response…

Special educators and speech pathologists were both able to distinguish adults with Down's syndrome from nonretarded adults with voice disorders based only on prolonged vowel samples. Listeners indicated that resonance differences may have helped them to identify Down's syndrome speakers. (Author)

Preliminary findings from a longitudinal study of 32 preschool children who stutter and 32 nonstuttering controls reveal 4 subgroups: (1) persistent stuttering; (2) late recovery; (3) early recovery; and (4) control. Comparative data for the groups regarding frequency of disfluency, acoustic features, phonologic skills, language development,…

Simultaneous recordings of auditory brainstem and middle latency responses were obtained in both vertex-ipsilateral and vertex-contralateral derivations in 22 children, ages 8-12. For specific recording conditions, the latencies of middle latency responses differ significantly between children with and without learning disabilities, offering…

The report describes a child with central auditory dysfunction, the first reported case where brain-stem dysfunction on audiologic tests were associated with specific electrophysiologic changes in the brain-stem auditory-evoked responses. (Author/CL)

Simultaneous auditory brainstem responses (ABRs) to click stimuli at 30 and 60 decibels were recorded from 16 full-term neonates with 4 different electrode arrays. Results indicated that ABR waveforms were morphologically similar to those recorded in adults. Waveform expression was variable with different electrode recording montages. (Author/DB)

A survey of 100 speech-language pathologists involved in the assessment and treatment of patients with dysarthria investigated their attitudes toward the Darley, Aronson, and Brown (DAB) method of classification. Results indicated that most clinicians, believing it helps in the design of a treatment protocol, used the DAB classification system.…

The perceptual assessment of voice disorders by speech pathologists and interjudge reliability were investigated through screening of 160 children (4-14 years old). Results demonstrated poor interjudge agreement between the listeners and indicate a need for more objective measures in the identification of voice disorders. (Author/SEW)

To assess diagnostic accuracy and test-retest reliability, two forms of a nonword repetition task were administered to 22 preschool children with specific language impairment and 22 controls. Nonword repetition scores provided excellent sensitivity and specificity for discrimination. Scores on nonword repetition and digit span tasks improved from…

Comments on studies that indicate delayed onset of canonical babbling may predict future language impairments. It cautions against the too-early assumption of the use of early perceptual and production capacities as clinical markers and warns that using lack of canonical babbling as a early index of language delay could lead to a high rate of…

This study evaluated an experimental articulation testing instrument for differentiating child speakers (N=21, ages 5:0 to 6:6) of African-American Vernacular English (AAVE) with atypical and typical phonologies. Significant group differences were observed, suggesting that the measure can differentiate typical and atypical development in this…

Stuttering has been considered a heritable disorder since the 1930s. There have been different models of transmission that have been proposed most involving a polygenic component with or without a major locus. In spite of these models, the characteristics being transmitted are not known. This study used two different tasks--a tapping task that is…

A panel of speech professionals was randomly presented with speech samples from four neurogenic and four developmental stutterers and was asked to classify them accordingly without any patient knowledge. Results support the view that, based on the patient's verbal output only, it is difficult to distinguish between neurogenic and developmental…

Nineteen students (ages 10-14) who had been identified during preschool or early elementary school as being at risk for auditory-language processing problems were followed for 5-7 years. Seventy-four percent of the at-risk subjects exhibited special needs profiles at follow-up. Seven students were not previously identified as language impaired but…

An evaluation of 3,469 infants at risk found that of those who showed late onset of canonical babbling, fewer than half had been diagnosed with a medical problem accounting for the delay. A follow-up study found those with delayed canonical babbling had smaller vocabularies at 18, 24, and 30 months. (Author/CR)
