APPERCEPTIVE HALLUCINATION

   Also known as hallucination of apperception. The term apperception comes from the Latin verb percipere, which means to perceive through and through. It translates loosely as 'conscious perception' and was introduced by the German rationalist philosopher Gottfried Wilhelm Leibniz (1646-1716). During the era of classic psychiatry, the term apperception was used to denote the process by which sense impressions or ideas are assimilated with the individual's pre-existing body of cognitions and emotions. In the classical psychiatric literature, the term apperceptive hallucination has been used as a synonym for both "reflex hallucination and "pseudohallucination.
