The sparse literature, especially involving dynamic considerations, concerning echolalia and echopraxia is reviewed. Two cases of schizophrenic reaction are presented in which the use of these mechanisms indicate a regressive manifestation of hostility toward and mockery of a feared mother. Thus nothing is digested that comes from the feared and hated person. Features of identification with the aggressor are also prominent, as both mothers used mimicry in a hostile, mocking manner. Consequent therapeutic technique is considered briefly.
