The advent of the computer has given rise to several types of reactions, ranging from fear, avoidance and sabotage, on the one hand, to patterns of headlong involvement and overuse comparable to addiction, on the other. The significance of the more extreme reactions, which may be labelled pathological or counter-productive, is discussed, as well as possible means of preventing such exaggerated responses. Approaches to modifying computer fear and avoidance are followed by proposed means of modifying computer overuse or addiction.
