Sensory processing is the ability to perceive, process and organise information that is received through our senses. Once we receive this information our brain reacts to these sensations and this is displayed in our behaviours and motor responses. As infants and children grow, so do their sensory development as they interpret and comprehend from their body and environment to respond in a consistent and meaningful manner. For efficient sensory processing, the seven senses below must work together for this to be achieved, which include;
Visual sense:
Is the ability to understand and interpret what is seen. The visual system uses the eyes to receive information about contrast of light and dark, colour and movement. It detects visual input from the environment through light waves stimulating the retina.
Auditory Sense:
Is the ability to interpret information that is heard. The auditory system uses the outer and middle ear to receive noise and sound information. They receive information about volume, pitch and rhythm. It is important for the refinement of sounds into meaningful syllables and words.
Gustatory Sense:
Is the ability to interpret information regarding taste in the mouth. It uses the tongue to receive taste sensations, and detects the chemical makeup through the tongue to determine if the sensation is safe or harmful.
Olfactory Sense:
Is the ability to interpret smells. It uses the nose to receive information about the chemical makeup of particles in the air to determine if the smell is safe or harmful.
Tactile sense:
Is the ability to interpret information coming into the body by the skin. It uses receptors in the skin to receive touch sensations like pressure, vibration, movement, temperature and pain. It is the first sense to develop (in the womb), and as such is very important for overall neural organisation.
Proprioceptive Sense:
Is the ability to interpret where your body parts are in relation to each other. It uses information from nerves and sheaths on the muscles and bones to inform about the position and movement of body through muscles contracting, stretching, bending, straightening, pulling and compressing.
Vestibular sense:
Is the ability to interpret information relating to movement and balance. The vestibular system uses the semi-circular canals in the inner ear to receive information about movement, change of direction, change of head position and gravitational pull. It receives information about how fast or slow we are moving, balance, movement from the neck, eyes and body, body position, and orientation in space.
Why is sensory processing important?
Sensory processing plays a crucial role in self regulating emotions. With sensory processing skills, children are able to better regulate their emotions and calm themselves down with things like deep breathing exercises, tight hugs, blowing pinwheels or bubbles, walking barefoot on the grass, smelling herbs and essential oils. Sensory processing also affects a child’s actions in their environment, from how they walk to how they interact with their peers and teachers. Sensory processing also promotes fine motor skills, builds language skills, develops cognitive skills, improves social skills.
