Sensory processing and information overload

Most behaviour is directly linked to how a person processes and reacts to the sensory input they receive through the senses. It is very common to observe sound, visual and tactile sensitivities or sensory overload leading to melt-downs, retraction into their own world or 'unacceptable' behaviour due to frustration.

Sensory processing and information overload

It is important to understand that we receive huge amounts of information through the senses of vision, hearing, touch, smell, taste and balance. The brain receives about 11 million bits of information each and every second of our waking day. However, we can only pay attention to around 70 to 80 bits per second, so one of the main functions of the brain is to filter, redirect or delete most information that comes in. Some people are not so good at this and either let too much information through or filter the wrong information out. This can lead to sensory overload and sensitivities, resulting in a range of difficulties, including sometimes 'autistic-like behaviour'. Much of this behaviour is simply a reaction to the unrelenting assault of information on the brain. Improve the sensory filtering and processing in the brain and behaviour will change for the better.

One of the ways the brain filters sensory input is by comparing the signals from the right ear and right field of vision, with those from the left ear and left field of vision. The brain uses these two separate and slightly different signals to, for instance, concentrate on a single sound source or limit our visual awareness. By training the brain to make better and faster connections between the two sides, it is possible to improve the filtering of sensory input, reduce sensitivities and boost attention.

Auditory processing in the brain

Sounds received through our right ear is mainly processed in the left brain half and sounds coming into our left ear are mainly processed in the right half.

Speeding up the brain

There is little doubt that faster and more efficient processing in the brain will help a person to perform better and achieve more. But is it possible to change how the brain processes information?

Synchronising the two sides of the brain

It is the left side of our brain that ensures that we understand language and produce speech, but it is the right side of our brain that looks after the intonation of our speech. This was discovered around 150 years ago, when doctors noticed that patients with a stroke on the left side of the brain often lost speech, and that those with a stroke on the right side mostly spoke in a monotonous voice, without any intonation, rhythm or stress.

Activating specialised functions

The adult brain of a human weighs about 1.4 kg (3 pounds), and in relation to the size of our body, is much bigger than what would be expected compared with other creatures. This large size does pose special problems for an effective communication between the two sides of the brain and this is probably the reason why specialised centres for specific processes developed in the human brain.
