Resource summary

Out of body and near death experiences
1 Outline
1.1 A pereption of floating outside one's body, or being able to see one's body from an exterior place.
1.2 Three areas of the brain associated to OBEs are the temporal lobe, parietal lobe and angular gyrus.
2 Research
2.1 Blanke et al 2005 - Found that OBEs were simulated in particpants with no history of OBEs by electrical stimulation of the right temporal-parietal brain area, suggesting a biological explanation.
2.2 Ehrsson et al 2007 - Stimulated OBEs using virtual - reality googles. Participants were then touched which made Ps believe that they were have an OBE.
2.3 Van Lommel et al 2001 - Studied 344 Ps who had been sucessfully resucitated after having heart attacks. 18% reported having a NDE during a period of low brain activity.
2.4 Irwin 1985 - Reported that OBEs occur with either very little or very high arousal.
2.4.1 Green 1968 - Found that 75% of Ps who experienced OBEs had very low arousal levels.
2.5 Greyson 1997 - Reported that during cardioverter-defibrillator implantations doctors induce heart attacks with pictures on the wall. During post-op recovery Ps guessed the image that was displayed on the wall and no results beyond chance occurence were found.
2.6 Gow, Lang and Chant 2004 - link belief in OBEs to personality – those who had experiences of OBEs were more ‘fantasy prone’, had greater belief in the paranormal and showed more somatoform dissociation – characteristics of believers.
3 Evaluation
3.1 Blackmore 1982 - Believed that OBEs occur if a person loses contact with sesnory inputs and perceptions occur from elsewhere whilst still awake.
3.2 Blackmore 2007 - Praised Ehrsson's 2007 research
3.3 Practical application - creating video games that give a high sense of reality.
3.4 Moody 1998 - After years of studying NDEs concluded that they were wonderful experiences for the people who had them.
3.4.1 However 15% of people who experienced NDEs described them as hellish.
3.5 Interpreted as a religious experience - many people report entering into a tunnel of light.
