Final answer:
Becci's therapist used exposure therapy to help her overcome her snake phobia.
Step-by-step explanation:
Becci's therapist helped her overcome her snake phobia through the use of exposure therapy, which is a technique used by cognitive-behavioral therapists. Exposure therapy involves gradually exposing the patient to the feared object or situation in a controlled and safe manner, helping them gradually reduce their anxiety and fear response.
In Becci's case, being placed in a room full of harmless garter snakes allowed her to confront her fear and realize that her anxiety was unfounded. The therapist's guidance and support throughout the process were crucial in helping Becci overcome her snake phobia.
