This study investigated comodulation masking release (CMR) in 42 children (ages 5 to 10) with a history of otitis media with effusion (OME) and 19 control children with no history of ear disease. Results indicated that monotic CMRs were reduced in children with hearing loss due to OME and these CMRs remained abnormally small for several months.…

A theory of neurolinguistic function is proposed to explain fluency and the production of stuttered speech disruptions. Stuttering results when the speaker is under time pressure and is unaware of the cause of dyssynchrony between the linguistic and paralinguistic components of speech which are processed by different neural systems but converge on…

The hypothesis that a person stutters because he believes in the difficulty of speech, anticipates failure, and struggles to avoid it, is said to be consistent with experimental findings on the metronome effect, the adaptation effect, the effects of white noise and delayed auditory feedback, and operant control of stuttering.

Analysis of use of positron emission tomographic measurements of resting-state regional cerebral blood flow in 29 men, 10 of whom stuttered, did not support the idea that developmental stuttering is associated with abnormalities of blood flow at rest. Findings did suggest an essentially normal functional brain terrain with a small number of minor…

Of 169 adult and adolescent stutterers studied, 112 reported family history of stuttering. Only 3 of the 112 reported birth or early childhood factors that might precipitate stuttering, as opposed to 21 of those without family history of stuttering. By considering these two conditions as separate factors in behavior, stutterers may be divided into…

Fifty adolescent or young adult stutterers and nonstutterers cancelled the auditory sensation evoked by bone-conducted sinusoidal signals. (Author)

This paper reviews evidence that characteristics of the perceptually fluent speech of stutterers change as a function of a number of variables and that, because these variables are difficult to fully control, comparison of the characteristics of the perceptually fluent speech of stutterers and nonstutterers as a method of studying stuttering…

This article reviews and critiques the research on possible genetic factors in stuttering. The failure to consider epidemiologic factors is thought to have biased previous research, but recent data provide evidence that spontaneous recovery and chronicity are influenced by genetic factors. Findings support previous conclusions about combined…

Children (ages 5-7, N=31) with expressive phonological impairments were tested on phonological awareness and compared with control children. Children with phonological impairments scored well below controls on phonological awareness and literacy, independent of other language problems. Results suggest that both speech impairment and literacy…

Comparison of the speech fluency and phonology of 18 boys (mean age 61 months) who stuttered and demonstrated either normal or disordered phonology found that the two groups were generally similar in terms of their basic speech disfluency, nonsystematic speech error, and self-repair behaviors. Predictions of the covert repair hypothesis of…

This paper, responding to Gathercole and Baddeley's commentary (EC 611 105), defends van der Lely and Howard's 1993 argument that deficits in verbal short-term memory (VSTM) do not cause children's specific language impairments (SLI). It is argued that while some children with SLI may have VSTM problems, the fact that many do not eliminates VSTM…

This article discusses the hypothesis of unilateral left hemisphere damage as an explanatory model for the neurological basis of specific language impairment considering both evidence challenging the theory as well as evidence supporting it. (Author/DB)

A theory of normal and delayed development of language is presented, arguing that linguistic capacity develops in gradual, sequential, critically timed phases; children with slowly developing brains have delays in storing utterances; a critical period for activation of experience-dependent grammatical mechanisms declines without optimal result;…

This study of 44 late-talking and normally speaking toddlers with and without histories of middle ear involvement revealed no differences in expressive language outcome attributed to history of middle ear involvement. There seemed to be intergroup differences in outcome on measures of articulation that were associated with history of middle ear…
