Document Summary
Some people have claimed that messages recorded backward on rock music produce dangerous effects on listener"s behavior. Even if present, back ward messages would have no effect on behavior. Is a stimulus is slightly weaker than the absolute sensory threshold, how often would we expect a person to be able to identify its presence? a little less than half the time. A one-eyed person can detect depth in many ways, but is unable to use these two ways: retinal disparity and convergence. People can detect stimuli weaker than physicist can measure. As you watch a car drive toward you, you do not perceive it as growing larger, even though its image on your retina grows larger. The name for this phenomenon is size constancy. One reversible figure can be seen either as a vase or as two profiles looking toward each other. This example illustrates the gestalt principle of figure and ground.
