Anxiety
Anxiety has been discussed and studied as a concept and
psychological phenomenon for a long time. According to The American
Heritage College Dictionary (1993), anxiety is “a state of intense, often
disabling apprehension, uncertainty, and fear caused by the anticipating
of something threatening” (p.61).
Spielberger defines anxiety as “the
subjective feeling of tension, apprehension, nervousness and worry
associated with an arousal of the autonomic nervous system.”
(Spielberger 1966a, p.16).
Spielberger further mainly divided anxiety
into two kinds. One is trait anxiety, which is more permanent
predisposition to be anxious. The other is state anxiety, which is
experienced with some particular events (Speiberger, 1966 a).
