Symbolic Functions
They are specific to humans and are the result of higher nervous activity.[1]
Distribution of symbolic functions [1][edit | edit source]
Phatic fuction[edit | edit source]
These include the ability to speak, read, write, calculate and think in abstract terms including semantics (the meaning of words).
Gnostic functions[edit | edit source]
They are the result of a higher synthesis of sensory perception. They make it possible to recognize objects by sight, hearing and touch.
Practical functions[edit | edit source]
It includes the ability to perform more complex purposeful movements
Symbolic functions and hemispheric dominance[1][edit | edit source]
Dominant Hemisphere[edit | edit source]
It is primarily responsible for phatic, less practical and least Gnostic functions. The dominant hemisphere mainly provides the following functions:
- Speech
- Reading
- Writing
- Counting
- Comprehension and repetition (words, sentences)
- Logical and analytical thinking
Non-dominant hemisphere[edit | edit source]
It ensures visual and spatial perception, behavior and orientation in the contralateral half of space. The majority of the population has a non-dominant right hemisphere, so this hemisphere will ensure the perception of the left half of space. Furthermore, the non-dominant hemisphere adds an affective and emotional component to speech.
