This is another reason to avoid superficial analyses based on isolated signals and to look for as many indicators as possible, especially subtle clues when one suspects that things are not as they seem. Manipulative politicians and salespeople come to mind for one reason or another. These are the body language signals that are discussed below: the results show that manipulating visual information about a limb using feedback reflects the tactile sensitivity of healthy participants to conditions in which there was no visual feedback from the limb`s movement. However, the direction of this effect seemed different from what was expected. The following body language signals are grouped by body parts. Body language of the legs and feet is more difficult to consciously control or falsified than body language of the arms, hands and face. Legs and feet can therefore give good indications about feelings and moods if you know the signs. The mouth is associated with very many body language signals, which is not surprising given its functions – obviously language, but also those related to infant nutrition, psychologically related to feelings of security, love and sex afterwards of one`s life. All these sound signals occur for a purpose. We may not know so easily what the purpose is, but being aware of it is the beginning to better understand it, in others, and perhaps also in ourselves. Often the most striking useless signals are ornaments or tusks – a kind of frimeur or protection. Left and right are for the person who gives the signals and makes the movements. One way to study the effects of sensitive incongruity is through the use of feedbacks.
When a mirror is placed perpendicular to the torso and a person puts his arms on both sides, the hand in the reflection of the mirror seems to occupy the same room as the hand behind the mirror. Performing symmetrical bilateral movements during the observation of the reflected image makes the person feel like they are looking at the hand behind the mirror and not the reflected image of the other hand. The incongruity between visual information and proprioceptive and motor signals can be generated by observing the reflected image while it expresses asymmetrical movements: the direction in which the arm appears to be moving is opposite to the intended direction of motion and the direction in which the arm appears to be moving. . . .
