How Audiovisual Integration Affects Cognitive Behavior

Humans have various different sensory organs but the five basic senses are sight, hearing, smell, taste, and touch. We are able to function on a day-to-day basis primarily because of these five senses.

Senses and Sensory Organs


Seeing anything happens when the brain is stimulated visually thus recognizing what our eyes see.


The brain is able to interpret sounds through our ears.


We have 400 smelling receptors which communicate with our brains to ascertain what it is we smell.


A majority of our taste buds are located on our tongues. The taste buds can differentiate between five tastes – salty, sweet, sour, bitter, and savory.


We feel everything through our skin. The particular neurons, which correspond with the brain, interprets the sensations we feel.

Cognitive Behavior

Studies published in The Journal of Neuroscience were conducted to see the timing of cognitive reactions in different parts of the brain. This was achieved through the synchronized stimulation of audiovisual, auditory, and visual incitements.

Audiovisual Stimulation

This is used by provoking the central nervous system using certain audio and visual signals. Audiovisual stimulation has been used in several forms of therapy to treat ADD, dementia, emotional disorders, sleep disorders, and many more.

Auditory Stimulation

By using specific sounds, this creates a reaction between the brain and the nervous system. It has been an effective treatment therapy for those suffering from autism, ADD, deafness, and blindness.

Deaf patients have been found to acquire an increased ability to process different sounds. Autistic patients who have been exposed to a therapy called Snoezelen Multi-Sensory Environment Therapy experience greater relaxation and learning processes.

Visual Stimulation

The retina in our eyes is responsible for visual recognition. Stimulation such as using positive images to create reactions is because the retina receives light from the images. It converts it into neural signals sent to the brain, thus resulting in the recognition of whatever it is we are looking at.

We have our eyes to see things, ears to hear sounds, a nose to smell, skin to feel sensations of touch, and our tongues to taste. Our sensory organs affect our cognitive behaviors as each sense affects our thoughts, feelings, and decision-making.
