A procedure in which an individual in inundated
with experiences in order to develop an aversion to an unwanted habit (e.g.,
continuously smoking cigarettes until the thought or sight of a cigarette makes
one feel sick) or to extinguish the disabling anxiety associated with a phobia
(e.g., a person who fears snakes is continuously presented with the feared
stimulus until it no longer elicits anxiety). This procedure is also called
flooding.
