Throughout our life, the 8 senses are the guides and motivators that our bodies use to connect us with the environment and each other. The 8 senses bring us growth, development and learning.

At Sense-able Connections, we use each of the senses to access a child’s brain potential throughout their development. By honing in on each sense, our team works to improve motor skills, sensory perception and processing to facilitate successful higher learning, whether behavioral or academic.


The auditory system is positioned together with the vestibular system inside the ear. This system enables a person to identify where a sound is coming from and to differentiate among various sounds. When sound enters the ear, both high- and low-frequencies are perceived. Higher-toned sounds, such as a person’s voice, carry a lot of information. A lower-toned sound, such as thunder, tends to be deeper and not carry as much information. The auditory system also helps to tune out extraneous auditory information in order to focus on pertinent sounds.

When this processing does not occur, a child might appear inattentive or unable to “listen.” There is a difference between hearing and listening. Hearing is the passive reception of sound. Listening is active and requires effort and intention: You must want to do it.

The visual system is the part of the central nervous system which gives us the ability to process visual detail, as well as enabling the formation of several non-image photo response functions. It detects and interprets information from visible light to build a representation of the surrounding environment.

The visual system is closely related to the development of normal movement patterns, and therefore, children need to perceive their environment visually in order to accurately orient themselves to their surroundings. Children who are sensitive to various visual stimuli may not explore or learn about their surroundings. As a result, they may have difficulty carrying out activities of daily living and attending to classroom tasks.

Related to the visual system are ocular motor skills: the smooth and coordinated movement of the eyes to attend to and follow objects and people in the environment. Controlled eye movements are needed to find and track a moving object, scan the environment, sustain eye contact on a fixed object or person, shift gaze from one thing to another (e.g., the blackboard to paper) and for eye/hand or eye/foot coordination skills.

Some children without any vision or ocular motor limitations get visually over-stimulated by their everyday environment. These children can be easily distracted by bright lights or a busy decor - (e.g., wall decorations) and be unable to make eye contact or visually attend to activities.

The gustatory system is the sensory system responsible for the perception of taste and flavour. In humans, the gustatory system is comprised of taste cells in the mouth (which sense the five taste modalities: salty, sweet, bitter, sour and umami), several cranial nerves, and the gustatory cortex. This system pertains to textures, tastes and temperatures that enter the mouth. When referring to the oral sense in relation to the therapy we offer children, we are usually discussing oral defensiveness or hypersensitivity to oral sensations (picky eaters). Oral defensiveness is usually seen in conjunction with tactile defensiveness. However, some kids seek out strong oral input or display excessive drooling, indicating hypo-sensitivity to oral sensations (messy eaters).

The olfactory system, or sense of smell, is the part of our sensory system used for smelling (olfaction). The smells of a rose, perfume, freshly baked bread and cookies...these smells are all made possible because of your nose and brain. The sense of smell, called olfaction, involves the detection and perception of chemicals floating in the air. Chemical molecules enter the nose and dissolve in mucous within a membrane called the olfactory epithelium. In humans, the olfactory epithelium is located about 7 cm up and into the nose from the nostrils.

This system pertains to the ability to detect and differentiate odors. Smell is the only system that has a direct route through the limbic system to the brain. Smell has a powerful influence on our behavior and often is a link to powerful emotions and memories. Many times we are unaware of the overwhelming influence smell holds.

The tactile system functions as both a protective sense and a discriminatory sense. The protective sense alerts a child to danger (e.g., hot/cold). The discriminatory sense provides information to the child about the quality of objects in the environment (e.g., soft/hard, rough/scratchy/smooth). Children can be over-responsive, under-responsive or combine a little bit of both. Difficulty in this system can also affect feeding skills.

This “hidden sense,” located in the inner ear, takes in information from the environment and sends it to the brain. The vestibular system registers the position of one’s body in relation to gravity and lets you know if it’s moving or still, or speeding up or slowing down. The vestibular system has a strong influence on the muscles that control posture, including the muscle tone and strength needed to sit in a chair, hold one’s head up or play a sport.

This is the sense responsible for detecting internal regulation responses, such as respiration, hunger, heart rate, and the need for digestive elimination. It is detected through nerve endings lining the respiratory and digestive mucous membranes. It completes the internal picture of how the human body is perceived, along with the vestibular and proprioceptive senses.

If interoception is well modulated, these sensations will be detected normally, and will not be overly agitating or needed in large quantities for regulation. A pounding heartbeat won't feel great, but it won't be traumatizing and it won't be craved. The same is true for hunger and thirst, as well as the feeling of the need to urinate or have a bowel movement.

This is another “hidden sense” that takes in information from the environment and sends it to the brain. It is registered by receptors located in muscles, tendons, ligaments and surrounding joints. The proprioceptive system tells the brain where body parts are and what they are doing in relation to each other and objects – in particular, at times when vision is occluded.

For example, this system helps children to subconsciously know the exact amount of force needed to throw or kick a ball, to reach for a toy/pencil, to write/draw or to just sit in a chair. The proprioceptive system is closely linked to the vestibular system. Both work together to help the individual know exactly what is happening within the body and to the body as we move through space and interact with our environment.

Proprioceptive input, a name for therapeutic heavy work or deep pressure to the muscles and joints, can be both calming and alerting to the nervous system. Unlike other sensory input, it is rarely overloading. It can improve a child’s body image, muscle tone and physical strength.
