It is the way our behaviour presents when exposed to phobic stimulus or irrational fear. One behavioural characteristic is panicking in the presence of the phobic stimulus; it can include crying or running away. Another is avoidance and it is when the person avoids the presence of the phobic stimulus and will do anything to prevent contact from the phobic stimulus, making it hard to go about everyday life. Final characteristic is endurance and it is when a person chooses to remain in the presence of a phobic stimulus.
