developed measurement tools that can be used in a clinical setting. According to Kinsella, no other researcher, besides Moody, has done more to "influence public opinion on the subject of NDEs" than Kenneth Ring. However, Bruce Greyson has the greatest output of material and remains the leading scholar in the field. The 1980s also introduced the research of Melvin Morse, another profile in the field of near-death studies. Morse and colleagues investigated near-death experiences in a pediatric population. They found that children reported NDEs that were similar to those described by adults. Morse later published two books, co-authored with Paul Perry, that were aimed at a general audience: Closer to the light: learning from children's near-death experiences (1990) and Transformed by the light: the powerful effect of near-death experiences on people's lives (1992). Another early contribution to the field was the research of British neuropsychiatrist Peter Fenwick, who started to collect NDE-stories in the 1980s, following appearance in television programs. The responses from Near-death experiencers later served as the basis for a book published in 1997, The Truth in the light, co-authored with his wife Elizabeth Fenwick. In the book the authors investigated more than 300 NDEs and concluded that the "subjective experience" is the key to understanding the phenomenon of NDEs. Co-operating with other researchers, among others Sam Parnia, Fenwick has reviewed and researched the potential relationship between near-death experiences and cardiac arrest Early investigations into the topic of near-death experiences were also being conducted at the University of Virginia, where Ian Stevenson founded the Division of Perceptual Studies in the late sixties. The division went on to produce research on a number of phenomena that were not considered to be mainstream. In addition to near-death experiences this included: reincarnation and past lives, out-of-body experiences, apparitions and after-death communications, and deathbed visions. Stevenson, whose main academic interest was the topic of reincarnation and past lives, also made contributions to the field of near-death studies. In a 1990 study, co-authored with Owens & Cook, the researchers studied the medical records of 58 people who were thought to have been near death. The authors judged 28 candidates to actually have been close to dying, while 30 candidates, who merely thought they were about to die, were judged to not have been in any medical danger. Both groups reported similar experiences, but the first group reported more features of the core NDE-experience
