Vision, hearing, balancing, voice and/or speech mechanism disability", which can be categorized into "sensory / voice and speech functions and related structures" (b2, b3, s2, s3) in ICF framework, was third (14.
Besides, the final model indicated that significant predictors of employment for people with disabilities sequentially included (1) currently married / living with partner, (2) driving car / riding (re-equipped) motorcycle, (3) higher educational level, (4) picked up by families, relatives, or friends / cannot go outside, (5) female, (6) 45-54 years old, (7) living alone, (8) 55-64 years old, (9) higher level of disability, (10) not 25-34 years old, (11) not necessary to use auxiliary equipments, (12) without limbs disability, (13) without losing functions of primary organs, (14) with vision, hearing, balancing, voice and/or speech mechanism disability, and (15) 35-44 years old (Model 1-4 / Table 5).
For category of the disability, the results showed that people with vision, hearing, balancing, voice and/or speech mechanism disabilities have the best employment outcomes, whereas those with intellectual disability, autism and/or chronic psychosis had poorer outcomes, being out of work or having relatively lower salaries.
Many people who stutter consult speech-language pathologists (SLPs) for assistance because these professionals are experts in the anatomy, physiology, and motor systems of the speech mechanism and can provide education and behavior modification to achieve greater control over speech (Cooper, 1997).
These behaviors are learned by association with success in overcoming a block, that is, when a person's speech mechanism ceases "to move forward to the next sound position" (Conture, 2001, p.
Although stuttering is believed to have some connection with neurological coordination or timing of the speech mechanisms, it is not an emotional problem or nervous disorder (National Stuttering Association [NSA], 1999).
The neurological basis of speech motor control has remained unknown until now because scientists cannot study speech mechanisms in animals and because non-invasive imaging methods lack the ability to resolve the very rapid time course of articulator movements, which change in hundredths of seconds.
They are involved in very serious research into trying to help people communicate who can't speak because of a stroke, illness or damage to speech mechanisms.
Prof Robert Knight, one of the researchers from the University of California at Berkeley, said: This is huge for patients who have damage to their speech mechanisms because of a stroke or Lou Gehrigs disease and cant speak.
He suggested that this cell death could lead to a 'glitch' in the speech mechanisms, 'blocking' the ability to pronounce certain sounds and causing the stammer.
Taking a narrower view than that of MacNeilage and his collegues, Tomasello says specialized speech mechanisms, not language in general, are all that have been located in the left hemisphere.
