Extra Sensory Perception - Ganzfield
- Preparing the reciever - relaxes in a room for half hour, recieving white or pink noise to eliminate sensory input from sounds. Halved table tennis balls are placed on the eyes and a red light shone in the face producing an overall mild sense of sensory deprivation. A relaxation tape is also played, hallucinations can occur.
- Sending the target - sender is in another soundproof room with opaque packets filled with 4 images. The sender uses mental intention to telepathetically relay the message.
- Judging the outcome - a session last between 15 and 30 minutes, then the reciever is relieved and presented with four images to rate from the mental imagery recieved. The order is randomised.
- Recievers should achieve about 25 per cent success rate.
- Ray Hyman produced flaws:
- Security - sensory leakage by experimenters talking to recievers.
- Statistical - wrong choice of tests and inappropriate forms of analysis
- Procedural - randomisation and documentation problems.
- Honorton and Ferrari conducted a meta-analysis that found 30% significance.
- Milton and Wiseman found no significance…
