DISCUSSION: Dr. Richard Yazmajian acknowledged the interrelatedness of the Isakower phenomenon and the primal scene but felt that the phenomenon comprised a broad range of experience referable to libidinal and ego regression, determined genetically by all phases of development and characterized by poor differentiation of self and object; such experiences are encountered in virtually every analysis where deep regressions occur. The Isakower phenomenon can not only be related to the primal scene but also to overwhelming masturbatory stimuli arising independently of the primal scene. Various screen memories where smell is the central element he has found to be derivatives of memory traces of early oral phases with incomplete differentiation of self and object.
