It is established that many behaviors can be observed by others. These behaviors are referred to as overt behaviors. Overt behaviors are anything that can be publicly observed by another person. An example of this is walking, running, hand gestures and speaking. Any person can observe these actions.
But, many behaviors can not be observed. These behaviors are referred to as covert behaviors. They are hidden behaviors which another person can not observe. These behaviors are classified as internal and private. Some examples are thinking, daydreaming, deception and reasoning. The behaviors can not be determined publicly by another person.
Another example of these behaviors is observing a woman walking. Walking is a covert behavior that this woman is demonstrating. But, the we can not observe the covert behavior which is possibly where she is going or why she is going to that place.
