Symbolic Functions

From WikiLectures

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.
