Venture into a new clinical office where an agoraphobic can manipulate a projected image of himself into an actual crowd, where a woman afraid of flying can desensitize herself through virtual reality exposure, where an ill-socialized adolescent or a depressed elderly patient can visit a virtual community. Dr Jeri Fink introduces the brave new world of psychotechnology with a mix of imagination, enthusiasm and authority. She logs on by exploring computer assisted therapeutic interventions for treating individuals and groups based on accepted theories of practice; next, she raises and answers questions about such pivotal attendant issues as the rise of Internet Addiction Disorder and the implications of cybertherapies for managed care; and finally, she supplies a resource guide to the Internet as a channel for professional communications as well as for professional reference.
