Sensory deprivation (Sendep) or perceptual isolation[1] is the deliberate reduction or removal of stimuli from one or more of the senses. Simple devices such as blindfolds or hoods and earmuffs can cut off sight and hearing, while more complex devices can also cut off the sense of smell, touch, taste, thermoception (heat-sense), and 'gravity'.
The Inkblots: Hermann Rorschach, His Iconic Test, and the Power of Seeing by Damion Searls. Look at the ink blots and tell me what you see. Itâs how millions of psychological tests have started for the best part of the past century.
There are many types of projective tests, but the most widely used is the Rorschach Inkblot Test. In this test individuals are shown various ambiguous inkblot pictures and asked to describe what they see. By analyzing the responses given by the people, psychologists attempt to understand the person's inner feelings, thoughts, and issues.
