This 1996 paper has the patina of scholarship, but is it really scholarly?
I have never been a follower of the so-called alien abduction thesis, but have presented various pieces about the "phenomenon" -- especially after the exchanges I've had, in the past, with the credible Will Bueche (a colleague of John Mack).
Alien abductions are, for me, a psychological or neurologgical matter incurred by various stimuli. You can find my suggestions via Google.
CDA notes the diminishment of interest in the matter.
