What is a stimulus shelter?

Stimulus shelter is a mechanism that shields us from the barrage of information coming our way every minute. An individual is constantly bombarded by television, mobile phone calls, text messages, emails, social networking messages and the resultant multi-tasking puts a lot of pressure on the brain. In such a situation, concentration and focus is lost and the person has to devise a method to filter out the unimportant stimuli and retain the important ones, by building a stimulus shelter.
