Transfer of fear reduction through systematic desensitization

Systematic desensitization therapy involves the presentation of fear-provoking situations through visualization As the visualizations cease to evoke emotional responses, the fear-provoking potential of the real situations decreases. Research has clearly shown that such transfer does indeed occur with a wide variety of fears. Transfer has been demonstrated, for example, with fear of small animals (Lang and Lazovik, 1963), interpersonal performance anxiety (Paul, 1966), classic phobias (Lazarus, 1961), test anxiety (Katahn, Strenger and Cherry, 1966), impotence (Wolpe, 1958) and frigidity (Lazarus, 1963). However, the nature of transfer has received little attention. Wolpe (1963) has claimed that transfer from therapy to the real life situation is almost complete and direct: “There is almost invariably a one-to one relationship between what the patient can imagine without anxiety and what he can experience in reality without anxiety”. This claim has received support from Rachman (1966) who found that fear reduction transferred immediately to the real situation in 82 per cent of his observations. Hoenig and Reed (1966) reported that after a brief delay, transfer effects were observed in the case of words representing fearful stimuli but were inconsistent in the case of the real stimuli. Agras (1967) found transfer to be delayed in all his cases. He further reported that, though all patients improved, a direct relationship between therapeutic progress and symptom reduction was not found. Both Hain et al. (1966) and Meyer and Crisp (1966) have described the failure of therapeutic effects to transfer to real life.These somewhat inconsistent reports may stem in part from the measurement of transfer effects at different times. Another possibility is that more fearful Ss may evidence less transfer than less fearful Ss. Lang and Lazovik (1963) reported that Ss who completed less than 75 per cent of the hierarchy showed little improvement although direct transfer effects were observed for less fearful Ss (those who complete 75 per cent or more hierarchy items). The present study of transfer effects was designed to remove confoundingof level of fear with extent of progress in systematic desensitization.
