| Abstract: | Behavioral and self-report measures of snake fear were obtained from three groups of male snake phobies (10 in each group) before and after systematic desensitization therapy. The stimulus hierarchy was presented to one group by using the standard imagination method; to another group by projecting the photographed scenes on a screen; and to the third group by enacting the same scenes in vivo before the group. Each group demonstrated substantial reduction in snake fear during treatment (t = 2.08-5.16, p = 0.05-0.0005), and there were no significant differences among the groups. A three week follow-up revealed further reductions in snake fear in some instances. |
