There have always been different stuttering theories, which give us different ways of seeing and understanding the problem.
However, it has not been possible to arrive at a global and demonstrable explanation of stuttering. Currently, there is a clear tendency to explain it as a multicausal speech disorder.
Today we will see the different theories that we can find depending on the field that explains it.
Neurophysiological area
- Genetics: Assuming that there is a hereditary basis in alterations in speech fluency is supported by a high family incidence. Likewise, this disorder is more predominant in boys than in girls. On the other hand, it cannot be concluded that the disorder is hereditary, but there seems to be a predisposition factor to suffer stuttering.
- Brain dominance: It has also been thought that this speech disorder could occur due to poorly established brain dominance. This was justified because a greater proportion of left-handed and ambidextrous people have been found among stutterers, who preferably use the right hemisphere of the brain, and not the left as is usually done. It has also been seen that stutterers show difficulties in planning and executing speech movements. This could be a condition for children to acquire fluency more slowly and increase repetitions and blockages during speech.
Psychosocial factors
The influence of the environment on the child, the people who interact with him, along with his way of being, the reactions to the lack of fluidity of the child on the part of the parents ..., all these are characteristics that can help establish a relationship of the Learning with the onset of speech disorder.
The negative attitude of the parents It is a determining factor in the maintenance and strengthening of stuttering. Attention to the mistakes the child makes can hinder the acquisition of fluency.
On the other hand, corrections can generate anxiety and fear towards speech and alter the learning process of our child's communication skills.
Linguistic factors
The fact that stuttering begins during the stage of extensive linguistic development can be related to different language disorders, such as language delay.
Conclusion
Stuttering is a fairly complex speech disorder in which there may be different subgroups of disorder with different causes.
There are several stuttering theories that point to various causal factors, such as genetic, family, learning or linguistic.
