Unconscious muscular movements often attributed to the supernatural through physical guidance, especially artistic activity (i.e. writing, drawing, painting, playing musical instruments, composing, dancing, and singing). Automatism was often attributed to spirits and the divine since ancient times when inspired activity was considered to be the gift of the gods. The prevailing contemporary view is that most automatisms are the product of secondary personalities who produce knowledge or information the person has learned and repressed or forgotten. The most common forms of automatism are automatic writing and automatic painting. In automatic painting, individuals who have little or no artistic training suddenly feel overcome by the desire to draw or paint in distinctive professional styles. They may feel guided by a spirit, or that an invisible hand is pushing theirs. In some cases, the style is recognizable as that of a deceased artist. Other types of motor automatisms include impulsive behavior, sudden inhibitions and sudden physical incapacities. Problems associated with automatisms include compulsion, obsession, and a feeling of possession. Sensory automatisms, those produced by an inner voice or vision, can include apparitions of the living, inspirations, hallucinations, and dreams.
