ILLUSIVE CONCEPTION

   Also known as spectral illusion. The two terms were introduced as synonyms in 1847 by the British surgeon Walter Cooper Dendy (17941871), denoting a subclass of'ghosts of the mind's eye', which itself constitutes a subclass of what Dendy calls "phantoms or ghosts. The notion of illusive conception may be seen as a forerunner of the present-day notion of "cognitive illusion. Dendy uses the term illusive conception in opposition to the term "illusive perception.
