Anxiety is a
physiological state characterized by
cognitive, somatic, emotional, and
behavioral components (Seligman, Walker
& Rosenhan, 2001).
These components
combine to create the feelings that we
typically recognize as fear,
apprehension, or worry.
Anxiety is often
accompanied by physical sensations such
as heart palpitations, nausea, chest
pain, shortness of breath, stomach
aches, or headache.
The cognitive
component entails expectation of a
diffuse and certain danger.
