We are constantly taking in information––particularly sights, smells, and sounds–– and our Sensory Integration skills help us make sense of it all. Sensory Integration involves the brain's ability to receive, process, and organize multiple sources of sensory information and transform that information into physical and emotional regulation that adhere to societal norms. Sensory Integration difficulties can interfere with peer relationships, participating in classroom activities, and getting adequate Sleep, all of which can contribute to difficulties staying engaged and learning.
Sensory discrimination supports the ability to process aspects of the sensory input from our environment, including duration, intensity, and spatial. Children with Sensory Integration and processing challenges can have discrimination difficulties in one or more sensory domains (e.g., tactile, auditory, visual, etc.).
Children vary in how they process sensory input (neurological threshold) and their behavioral response (both action and reaction) which contribute to their sensory modulation. There are some basic patterns of Sensory Integration and modulation however children can have any combination or may react differently in different contexts:
In addition, some children with Sensory Integration difficulties may experience sensory-motor based challenges in organizing vestibular (related to gravity and movement) and proprioceptive (related to the position of our muscles and joints) input, which may impact balance, body and spatial awareness, and motor planning. This can potentially contribute to challenges, in completing multi-step directions related to physical tasks, and engaging in unstructured play with peers, and lead to low self-confidence or frustration.
Difficulties with Sensory Integration often, though not always, co-occur with developmental disorders, including ADHD and autism, which may be driven in part by differences in executive function. Efficient Sensory Integration frees up cognitive resources to support executive functions, and in turn efficient executive functions help modulate Sensory Integration making them closely intertwined. Because difficulties with Sensory Integration are tightly connected to cognitive, physical, and social-emotional well-being, students can best be supported through relationship-building and Self-Regulation supports, in addition to traditional sensory supports.
