Change blindness

Explanation:

Change blindness describe a situation in which an observer fails to detect an important details of an object in a scene due to limited attention. It also occur as a result of failure on the part of the observer to notice the movement or disappearance of an object.

Example of change blindness is when an observer is discussing certain subject matter with someone, whereas the attention of the person has shifted to other areas but the observer continues the discussion on same subject matter. Here, the observer fails to spot changes in object's behaviour before continuing with the discussion.

A number of factors can cause change blindness;

-Limited attention on the part of the observer. He fails to pay close attention to the object hence miss vital change in the object.

-it could also be as a result of damage or injury to the brain hence unable to notice either major or minor change of an object.

One of the remedy to change blindness is to pay close or maximum attention to details.
