  1. Perceptual Interpretation

  2. Sensory Deprivation • What happens when vision is restricted from birth? Critical Period

  3. Willed Deprivation Pol Pot of Cambodia

  4. Perceptual Adaptation • In vision, the ability to adjust to an artificially displaced or even inverted visual field.

  5. Perceptual Set • A mental predisposition to perceive one thing and not another. • Based on schemas; why? Kiss the Guy

  6. Context Effects • Based on immediate context, not schemas. • You do not hear the word, but can guess at it based on the context it was said in.

  7. Extrasensory Perception • Refers to extraordinary perception such as • Clairvoyance – awareness of an unknown object or event • Telepathy – knowledge of someone else’s thoughts or feelings • Precognition – foreknowledge of future events • Research has been unable to conclusively demonstrate the existence of ESP

  8. Ganzfeld Procedure • Bem & Honorton, 1994 • All sensory information reduced • “receiver” in reclining chair in sound proof chamber with ping-pong balls, red light, earphones, white noise • In Separate room, “sender” concentrates on visual stimuli • 32% hit rate better than chance • Has not been replicated • Experimentation has not yet given scientific support
