Alien abduction claimants (also called abductees and experiencers) are people who have claimed to have been abducted by aliens. The term "abduction phenomenon" describes claims of non-human creatures kidnapping individuals and temporarily removing them from familiar terrestrial surroundings. The abductors, usually interpreted as being extraterrestrial life forms, are said to subject experiencers to a forced medical examination that emphasizes the alleged experiencer's reproductive system.
The first alien abduction narrative to be widely publicized was the Betty and Barney Hill abduction in 1961. Since that time, the credibility and mental health of alleged experiencers has taken on great importance to those seeking to determine the veracity of the abduction claims. Mainstream academics and members of the skeptics movement generally doubt that the phenomenon occurs literally as reported, and have proposed a variety of alternate explanations.
Such skeptics often argue that the phenomenon might be a modern-day folk myth or vivid dreams occurring in a state of sleep paralysis. On the contrary ufologists and paranormal researchers hold positions closer to the face-value of abduction claims. The discovery of common psychological traits shared by abductees would have the potential to determine a neurological explanation for the claims, while other commonalities or differences may serve to reinforce that the claims of the experiencers do in fact correspond with objective reality.
As a category, abductees have some psychological characteristics that render their testimony suspect. Dr. Elizabeth Slater conducted a blind study of nine abduction claimants and found them to be prone to "mildly paranoid thinking," nightmares and having a weak sexual identity. According to Yvonne Smith, some alleged abductees test positive for lupus, despite not showing any symptoms.
Alleged abductees are seen by many pro-abduction researchers to have a higher incidence of non-abduction related paranormal events and abilities. Following an abduction experience, these paranormal abilities and occurrences sometimes seem to become more pronounced. According to investigator Benton Jamison, abduction experiencers who report UFO sightings that should have been, but are not, reported by independent corroborating witnesses often seem to "be 'psychic personalities' in the sense of Jan Ehrenwald."
