The invention described herein provides computer-implemented methods and systems for alleviating an abnormal behavior, such as a behavior associated with a fear, abnormal activity, or obsession. It has been found that behaviorally abnormal self-sustaining behaviors may be unlearned or diminished through directed forms of computer-implemented interaction. The computer-implemented interaction is generally directed to reduce the neurological representations of inputs and actions associated with the abnormal behavior. The interaction will typically comprise strategically and repeatedly presenting computer-implemented stimuli including context related to the abnormal behavior. The computer-implemented stimuli are then repeatedly presented and altered over time in a manner that alleviates the abnormal behavior. For example, the content of the computer-implemented stimuli may change to gradually vary in their ability to trigger an episode in the person. In this manner, the neurological representation pertaining to the undesirable behavior may be gradually reduced.
