 Paranoiac-critical method is a technique invented by Salvador Dalí which consists of the artist invoking a paranoid state (fear that the self is being manipulated, targeted or controlled by others).The result is a deconstruction of the psychological concept of identity, such that subjectivity becomes the primary aspect of the artwork.Parsemage is a surrealist and automatic method in the visual arts invented by Ithell Colquhoun in which dust from charcoal or colored chalk is scattered on the surface of water and then skimmed off by passing a stiff paper or cardboard just under the water's surface.
