Overview
Anxiety is a physiological state characterized by cognitive, somatic, emotional, and behavioral components. 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, or headache.
Historical Perspective
Sigmund Freud recognized anxiety as a "signal of danger" and a cause of "defensive behavior". He believed we acquire anxious feelings through classical conditioning and traumatic experiences.
We maintain anxiety through operant conditioning; when we see or encounter something associated with a previous traumatic experience, anxious feelings resurface. We feel temporarily relieved when we avoid situations which make us anxious, but this only increases anxious feelings the next time we are in the same position, and we will want to escape the situation again and therefore will not make any progress against the anxiety.
