Elements of thought:

© SPMM Course 6. Disorders of Thought:

Normal thinking: Normal thinking is of three types (or functions):

  1. Fantasy/dereistic thinking or autistic thinking: There is no goal direction, unrealistic - daydreaming type. Predominant in cluster A personality, dissociation and pseudologia fantastica.
  2. Imaginative thinking: Again fantasy elements but admixed with memory, involving abstract concepts but goal-directed and does not cross boundaries of possibility and realism. Determining the tendency of thoughts preserved e.g. lateral thinking.
