Problem:A counseling psychologist is interested in three types of therapy for modifying snake phobia. However, she does not believe that one type of therapy is necessarily best for everyone; instead, the best type might depend on the severity of the phobia. Undergraduate students enrolled in an introductory psychology course

who volunteer are given the Fear Schedule Survey (FSS) to screen out those who show no fear of snakes. Those displaying some fear are classified as either mildly, moderately, or severely phobic on the basis of the FSS. One third of subjects withineach level of severity is randomly assigned to a treatment condition (treat): systematic desensitization (des), implosive therapy (impl), or insight therapy (insig). After the end of treatment, each participant completes the Behavioral Avoidance Test (high scores indicate a better outcome, less phobic).

**QUESTION I NEED TO ANSWER/HELP** This question pertains to the snake phobia study. Assume that there is an interaction effect, use the information in the graphs and output to provide a practical interpretation of the study results. Think in terms of whether or not a treatment works better or worse for a particular phobia severity level.
