Fear is a normal human emotional reaction - it is a built-in survival mechanism with which we are all equipped. Fear is a reaction to danger that involves both the mind and body. It serves a protective purpose – signalling us of danger and preparing us to deal with it. The major components of fear are sensations, feelings, cognitions and behaviours. Fear can be individual or collective such as expressed in the national fear in the United States related to terrorism. The Washington DC sniper attacks caused widespread fear in a large geographic region far out of proportion to the real danger. Individuals must cope with fear on a daily basis in a myriad of forms: financial fears, health fears, relationship conflict fears, dental appointments, fears about the future etc. This new book collects important research which helps shed light on important issues in this field which touches all of us each day.
