Forms of systemic speech underdevelopment
A mild degree of systemic speech underdevelopment is characterized by minor disturbances in sound pronunciation. The child begins to stammer only when he tries to say a complex phrase. He loses secondary lines of meaning in his attempts to convey the main idea. The child cannot use prepositions, “loses” conjunctions, does not always form the “noun-adjective” chain correctly, and gets confused in quantitative characteristics. Vocabulary is less than that of peers.
With an average degree of systemic underdevelopment of speech, the child “floats” in cases and genders and does not coordinate them with each other. As for speech, a violation is recorded only when trying to pronounce sounds of one group. Complex everyday words remain an unconquered peak for the baby. Words united by one semantic line are designated by the child as one word. For example, a sofa, a wardrobe, a TV, a carpet - this is all “home”.
Severe form of systemic speech underdevelopment.
The child cannot form a phrase from words, hence the incoherent speech. One sound can mean both “mother” and “eat”. The problem is in the pronunciation of several sound groups at once: voiced, voiceless, hissing, voiced - all are pronounced incorrectly. The child perceives speech with inhibition. The speech contains incorrect use of cases and numbers.
Systemic underdevelopment of speech against the background of mental retardation is complemented by increased physical activity, inability to concentrate, and poor memory.
