F. Matthias Alexander developed an ability that avoided what negative bodily issue?
Alexander Technique The Alexander Technique (A.T.), named after Frederick Matthias Alexander, is an educational process that attempts to develop the ability to avoid unnecessary muscular tension by retraining physical movement reactions. Alexander believed the individual's spatial self-awareness was related to psychological conditioning; questionably trained foundation habits of posture can be unsuitably added into procedural skills. Alexander observed that those whose goals justified it necessary to have trained themselves to overcompensate could not trust their judgment of physical orientation and required effort, (their "sensory appreciation.").
Calypsis Calypsis ( "καλυψις" --- "kalupsis" or "kalypsis".) is the act of covering, concealing, hiding, or veiling. In kinesics, the science of body language, calypsis is the act of covering or concealing certain parts of one's own body. Calypsis is a type of closed, negative or defensive body language used to express disapproval, discomfort or fear in certain situations. The term usually refers to the act of covering or concealing one’s face, or sexually attractive parts (including certain sexually attractive clothing), especially in the presence of someone who is a sexual turn-off (extremely anerotic), or someone who is uncomfortable to be around. The term "calypsis" was derived from the Greek "καλυπτω" ---"kalupto" or "kalypto", meaning to cover, to veil, to hide, or to conceal. Calypsis is a type of closed or negative body language often expressing extremely anerotic feelings, sexual abhorrence, scorn and contempt toward someone viewed as a sexual turn-off in terms of physical appearance, in terms of personality and social behavior, or both. The term calypsis can also refer to a bride placing a veil over her face during her wedding while preparing to marry her groom, or to a criminal concealing his/her face with a ski mask while perpetrating a burglary, robbery, or sniper attack. Calypses (plural of calypsis) are done in many different ways by various people in various situations for various reasons (including for defensive purposes), and are often done subconsciously like most other forms of body language.
