Nature and Causes of Stuttering

There is no single cause of stuttering to this day. Many researchers have come out a variety of results, based on some psychological and other neurological causes. There is another area that says, stuttering is a homogenous disease, but that’s not controversial. He says that stutterers suffer from one fundamental problem. Despite popular theories on the basis of heterogeneity of the disease.

One theorist claimed that since there is no measurement and causes of fluency, is more difficult to determine the cause of the disorder. For a long time, theorists believed that the concept of organic continuation or worsening of stuttering disfuency normal. However, these premises and the models are subjected to further tests and studies.

Further support for the study of stuttering, theorists have tried to categorize, and a subgroup who stutters. The first is the serious, such as the grouping variable. Several studies have used the sub-dominant mixed analysis so far. Meanwhile, an interesting sub-group is more mature of the four tracks the development of the formwork.

A model presents a fluency in two very important points to understand the categories of stuttering. First, the stuttering problem shows the temporal processing. Second, stuttering shows an imbalance between the capacities of the liquid supply system, and calls on the environment.

Once the model of fluent speaking, the type and sub groups of stuttering is formulated. First, the speech motor control sub-groups with two different, otherwise known as dyspraxic stuttering and stammering controls breathing. The first characteristic of the phonological and fluency problems, causing delays the appearance of intelligible words and phrases, articulation problems, and slow speech rates.

For example, some adults can be difficult to pronounce long words, and inconsistent articulation errors. Thus, stuttering is a long and unfamiliar words.

The second difficulty is directly related to the voluntary control of muscles of respiration. Therefore, children who stutter are likely to have asthma, allergies and upper respiratory problems. This disease is characterized unvoiced blocks and prolongations.

Some theorists also consider the language processing problems, the main etiological factor. Many children show delayed language development. This general category of the so-called linguistic stuttering. There are three types of sub-groups. The first involves the development of late aspects of language processing. The second word finding problems, and retrieval. The third generation of the problems associated with complex grammatical forms and includes the last auditory processing problems.

The second subgroup includes the cognitive processes. Problems in this area leads to disfluent speech. However, one theorist is likely that a person who stuttered in cognitive abilities that are better language and speech motor skills.

Psychologically related factors can not be eliminated in the sub-groups of the causes of stuttering. Anxiety is an important factor in stuttering. This is a critical factor in the severity of stuttering.

Theorists, these clusters is mainly based on the current tests. The sub-groups of stuttering has yet to be investigated and experimented.
