The study, published in Frontiers in Psychiatry on April 23, showed 424 participants segments of the Sony Pictures film Spider-Man 2, the Marvel film Ant-Man, a natural scene or the Marvel opening credits scene. Prior to viewing and after viewing they measured the participants' responses in an online quiz that assessed their socio-demographic variables, familiarity with the films and phobic symptoms.

The team showed watching Spider-Man 2 alleviated some of the symptoms of spider phobia. Post-viewing phobia symptoms were decreased, relative to pre-viewing, by 20%. Similar results were seen with Ant-Man.
