Although cerebral anoxia is not thought to be responsible for triggering near-death experiences (NDEs), the issue is not so clear in the case of hypercapnia. Detection of normal blood gases in Michael Sabom's (1982) case study seems to be the major reply to suggestions that hypercapnia may have a causal role in NDEs. We argue, however, that routine arterial measures of blood gases are not a reliable indicator of cerebral levels. 相似文献

Learning to be possessed has been described elsewhere by the writer as a form of pathogenic relating begun when children are taught by adults that they will receive a lesser penalty for misbehavior if they can show they were not responsible, such as if it were caused by an evil agent or the Devil. It was suggested that learning to be possessed can be an underlying cause of psychopathology, the delusion of persecution in particular. Two short stories by the distinguished American writer Edgar Allan Poe are examined to develop the formulation of learning to be possessed, especially when it has passed to a delusion of persecution. Two propositions are offered: (1) Where it appears that a family member is murdered by a delusional assailant by accident, it is not an accident; and (2) the delusion of persecution entails a memory loss so that the murderer not only can claim lack of personal responsibility for the act, but also spares himself the guilt of having broken a fundamental taboo. Further comparison is made between learning to be possessed as a cause of delusion, and the psychoanalytic theory in which the defense mechanism of projection is central. In the latter theory, interpretation of the delusion is critical; whereas in the former, interpretation is counterproductive because it merely reinforces the delusion.Probably a note of appreciation is due the writer's daughter Cary, who at age 14 is an expert at badgering her father for help with homework assignments. For several weeks the writer was alternatively pestered and cajoled to help Cary with her Poe Project for high school English which required an essay analyzing the work of a great American writer denigrated by the author as weird by his recollection formed decades earlier. Cary's persistence required the author to consider Poe anew, to recognize his unwarranted earlier prejudice, and to recognize that Poe offered him a gift of understanding regarding a topic about which the author had been thinking for several years, namely that form of pathogenic relating named learning to be possessed. 相似文献

This article attempts to assist the cognitive understanding of children and adults with significant physical disability. A discrimination is offered between disability and handicap. Common cognitive schemes and irrational beliefs of people with physical disabilities are explored. The development of belief systems from a social learning perspective and several cognitive assumptions of parents and families of children who have physical disabilities are presented. Finally, certain self evaluative beliefs specifically related to physical disability are examined in terms of how they relate to self image and, concomitantly, behavior. The article offers information arrived upon from the author's clinical practice as well as the author's personal experience as a person with a physical disability.Dr. John D. Sweetland, received his Ph.D. in Clinical and School Psychology from Hofstra University in 1979. His doctoral dissertation involved the application of a Rational Emotive Education program specifically for severely physically disabled children. He is a licensed psychologist in New York State, a school psychologist with the Port Washington Public Schools and in private practice with offices in Merrick and Massapequa, Long Island. Dr. Sweetland had polio and is semiambulatory. He was also a gymnast and a nationally ranked competitive acrobat. 相似文献

In the discussion of the responsibilities of society to the HIV infected and uninfected, a serious question seems to have been left out of the picture: To what extent are people who are not infected, have no special relationship to the infected and have no professional responsibilities for the care of AIDS patients under an obligation to come to the aid of people with the HIV? In this paper, I shall examine our responsibilities, as members of society, for the welfare of others to whom we may or may not have a special relationship. I shall argue that those responsibilities flow from the conditions that structure our transactions with others; conditions that make such transactions possible. 相似文献

Growth systematically changes the body proportions of both humans and animals so that the ratio of head height to body height decreases with age. Prior studies have demonstrated that body proportions provide effective information for age perception. To test the proposal that illustrators incorporate this information into their drawings, measurements were made of the head and body heights of 100 pairs of animals appearing in children’s picture books. In 93 pairs, the animal intended to be perceived as older had a smaller head-to-body ratio than did the younger animal. Ratings collected for 25 of these pairs showed that both perceived age and cuteness are significantly correlated with body proportions. The magnitudes of the correlations were only modest, suggesting that other aspects of the drawings influenced perceived age and cuteness. In addition, observers reported that body proportions are only one of a variety of factors influencing age and cuteness perception. As has been found in other studies, perceived age and cuteness were negatively correlated. 相似文献
