What is the difference between extrasensory perceptions and supranormal perceptions?
Let us define these concepts precisely. An extrasensory perception is a perception that “takes place without the involvement of the senses”. It describes what is perceived without the participation of the physical senses. But without the senses perception is not possible. It is an absurd concept though certain persons try to “send thoughts” to other people. This is irrelevant. If a person goes into a floatation tank, his or her physical senses are not stimulated. Nevertheless, that person still has many perceptions: colors, images, sounds, synesthesian sensations, odors, etc. This would demonstrate the existence of perceptions existing without the participation of physical senses. But in fact, these perceptions are not separated from the physical senses. An extrasensory perception would be “a perception happening without the involvement of the brain”, something that is not possible. On the contrary the sensory deprivation experience underscores certain particular abilities of the brain
