As third level reversals come from the very core of ones' being, they are very powerful in their meaning. It has been discovered that children begin speaking in reverse before they learn to speak forwards. This indicates that forwards speech is learned in order to protect ourselves from those who would use our true feelings against us. As children are born without inhibitions, it is only logical that they would learn to speak from the unconscious first, then learn to speak forwards to keep their thoughts and feelings from being known, like a built in defense mechanism. A child's Reverse Speech progresses much like their forward speech development.
Children begin speaking in reverse at about four months of age, using only one word reversals.
As they grow older they begin to put more words together and by the time they are eighteen months old, they begin using metaphors. The metaphors children begin using are handed down to them from thelr parents. By the age of two years, the child's reversals are very complex, the personality and future behavioral patterns are being formed. Learning Reverse Speech is similar to learning a new language. The unconscious mind does not use all the colorful and detailed language that we learn to use in speaking forwards.
