Data on disfluencies in the speech of non-stuttering adults are relevant to several aspects of the assessment and treatment of adults who stutter. Currently, very few sources provide relevant data. In the existing literature on normally fluent speakers, there is no consistency in sample length or topic or in which types of disfluency are counted.…

The language transcripts of seven children with Down syndrome (DS) and seven typically developing children with comparable mean length of utterance levels were compared for verb argument structure. Findings suggest that syntactic difficulties may delay children with DS in overcoming the optional subject phenomena and the lesser number of anomalous…

This study of rapid picture naming by 20 normally developing children (mean age 11 years) found significant differences between two-and three-dimensional pictures for higher level vocabulary items, but not for lower-level vocabulary items, suggesting that dimensionality may be a critical feature for rapid lexical access for higher-level picture…

A sociolinguistic, semantic analysis of intonation was conducted on a 15-minute natural interaction between an aphasic speaker, his wife, and his neighbor. Findings indicated the neighbor made more use of two dimensions of intonation, specifically pitch movements referring to shared information and marked tones, when addressing the aphasic speaker…

Three children with developmental apraxia of speech (DAS) identified syllables in words, judged intrasyllabic sound positions, and constructed syllable shapes within monosyllabic frames. Results suggest that DAS children demonstrate an apparent breakdown in the ability to perceive "syllableness" and to access and compare syllable representations…

This study investigated the preservation of second formant transition acoustic cues to intelligibility in speech produced during simultaneous communication (SC) from a locus equation perspective with 12 normal hearing, experienced sign language users. Results were consistent with previous research indicating that temporal alterations produced by…

Conversational speech of five children who stutter was recorded and then portions manipulated to modify interval duration and vowel duration. Results indicated that both interval and vowel durations moderately affected listeners' perception of stuttering. Generally, repetitions with short vowel and interval durations were judged as more…

Fifteen children (grades 3-5) with specific language impairment (SLI) were asked to define 10 common nouns. Children with SLI scored significantly lower than children with typically developing language for both content and form. Results suggest that lexical access and/or lack of metalinguistic knowledge were potential causes for the lower scores…

This study examined articulation in 13 Dutch individuals (ages 7-29, IQs 38-83) with Prader-Willi syndrome using a picture naming test with transcribed samples subjected to analyses for articulation errors. Results suggest that the impaired articulation found is a function of IQ and that with increasing age, phonological problems gradually resolve…

Speech samples of 79 dysarthric patients were judged for voice quality, articulation, nasality, and prosody as well as overall intelligibility. Application of a multiple regression model found that intelligibility can be expressed as a linear combination of weighted perceptual dimensions with articulation as the strongest contributor to…

This introductory article introduces papers that present examples of neuroimaging applications in the field of communication sciences and disorders. It notes that neuroimaging studies were usually an outgrowth of earlier behavioral research or clinical observations with knowledge of the disorder's behavioral characteristic critical to development…

Discussion of how functional neuroimaging has been applied to the study of speech production first reviews neuroimaging methods and limitations, then describes two approaches to study of the relevant speech areas: comparison across different language production tasks and comparison of effects of different stimuli within a single task. Examples…

Studies of American Sign language including functional magnetic resonance imaging of deaf signers confirms the importance of left hemisphere structures in signed language, but also the contributions of right hemisphere regions to sign language processing. A case study involving cortical stimulation mapping in a deaf signer provides evidence for…

Positron emission tomography imaging was used to evaluate the brain's response to auditory stimulation, including speech, in deaf adults (five with cochlear implants and one with an auditory brainstem implant). Functional speech processing was associated with activation in areas classically associated with speech processing. (Contains five…

This article proposes a neurobiological account of reading and reading disability suggesting that for normally developing readers, the dorsal (tempo-parietal) circuit predominates at first, and in conjunction with premotor systems, is associated with analytic processing necessary for learning to integrate orthographic with phonological and…
