Ophavsmanden til teorien er A. Jean Ayres. Hun er en amerikansk ergoterapeut og psykolog, der i 1960erne begyndte at udvikle sanseintegrations teorien. Hun udviklede smagssans
teorien for bedre at kunne beskrive og forudsige specielle sammenhænge mellem udviklingen af sansemotorisk adfærd, neurale processer og indlæring. Hun påviste, at dårlig sansebearbejdning og – samordning i hjernen er årsagen til mange motoriske, indlærings- og adfærdsmæssige problemer.
Sensory experiences include touch, movement, body position,vision,smell,taste, sound and the pull of gravity. The process of the brain organising and interpreting this information is called sensory integration. Sensory integration provides a crucial foundation for later, more complex learning and behaviour.
Some signs of Sensory Integration Dysfunction:
Difficulty learning new movements
Activity level unusually high or low
Poor body awareness
Inappropriate response to touch, movements, sights or sounds
Poor self esteem
Social and/or emotional difficulties
Overly sensitive to touch, movements, sights, or sounds. Behavior issues: distractible, withdrawal when touched, avoidance of textures, certain clothes, and foods. Fearful reactions to ordinary movement activities such as playground play. Sensitive to loud noises. May act out aggressively with unexpected sensory input.
Unusually high/low activity level. Constantly on the move or may be slow to get going, and fatigue easily.
Delays in academic achievement or activities of daily living. May have problems in academic areas, despite normal or above normal intelligence. Problems with handwriting, scissors use, tying shoes, buttoning and zipping clothes.
Poor self concept. May appear lazy, bored, or unmotivated. May avoid tasks and appear stubborn.
Underreactive to sensory stimulation. Seeks out intense sensory experiences such as body whirling, falling and crashing into objects. May appear oblivious to pain or to body position. May fluctuate between under and over-responsiveness.
Coordination problems. May have poor balance, may have great difficulty learning a new task that requires motor coordination, appears awkward, stiff, or clumsy.
Poor organization of behavior. May be impulsive, distractible, lack of planning in approach to tasks, does not anticipate result of actions. May have difficulty adjusting to a new situation or following directions. May get frustrated, aggressive, or withdraw when they encounter failure.
