%A Michael Jawer %J Journal of the Society for Psychical Research %T Environmental Sensitivity: Inquiry Into a Possible Link with Apparitional Experience %X Psi researchers often use the term ?sensitivity? when theorizing that certain persons may be more apt to register anomalous influences than others. Through a review of the literature, it is argued that some individuals are disposed toward a range of innate sensitivities that, in novelty as well as intensity, distinguish them from the general population. It is hypothesized that such persons will exhibit greater susceptibility to a range of environmental factors including allergies, migraine headache, chronic pain and chronic fatigue. Furthermore, it is suggested that sensitive individuals will report a higher than average degree of psi perception as well as apparent electromagnetic influence. Through a 54-item survey designed by the author, the following issues are evaluated: the extent to which persons who describe themselves as ?sensitive? appear to be affected by such factors; whether their immediate family members may be similarly affected; to what extent environmental sensitivity parallels apparitional experience; and how such findings compare or contrast with questions asked of a control group. Based on both the literature and the survey results, the author argues that sensitivity is a bona fide neurobiological phenomenon. While no single factor in a person's background is likely to distinguish him/her as ?sensitive,? eight demographic or personality factors are found to be statistically significant. If further studies were to document similar results, a more tangible basis would be provided for the study of apparitional experience than has been possible to date. %N 882 %K neurobiology, sensitive, sensitivity, survey, environmental, anomalous, perception, migraine, allergy, synesthesia, nightmares, sleep, disorder, chronic, pain, fatigue, fibromyalgia, psi, apparition, apparitional, gender, women, female, laterality, handedness, trauma, childhood, early, depression, alcoholism, electrical, chemical, immune, fantasy-prone, imagination, absorption, mystical, transliminal, transliminality, electromagnetic, personality, temperament, introversion, extroversion, ambidextrous, first-born %P 25-47 %E Christopher Roe Ph.D. %V 70 %D 2006 %I Society for Psychical Research %L cogprints4846
