Causes of acoustic dysgraphia
The occurrence of acoustic type dysgraphia is based on a violation of phonemic hearing and perception. They help to correctly recognize the sound structure of a word, determine the number of syllables, the location and exact meaning of the phoneme.
Zones located in the temporal regions of the brain are responsible for differentiating sound images of words. It is here that the acoustic signal is encoded and transmitted to Wernicke's area, where the received information is analyzed and synthesized. Violations that arise in these zones lead to incorrect phonetic perception.
The causes of violations can be various factors:
- Intrauterine lesions of the fetal brain.
- Infections during pregnancy.
- Serious illnesses of a child at an early age.
- Social or psychological reasons (insufficient amount of communication with the child, bilingualism, pedagogical neglect).
There are also cases of hereditary disorders.
