Optimally, a child's experiences with his parents are smoothly incorporated and synthesized by the ego toward the end of mastering the drives and enhancing the ego's autonomous potential. If the relationship interferes with this autonomous potential, the ego institutes defenses against this experience that prevent the establishment of introjects utilizable for ego adaptation. Instead, the parental relationship becomes fragmented from the rest of the ego. In psychoanalysis the analyst becomes cathected and consequently there is a relative withdrawal of cathexis from introjects, including destructive and archaic ones. The impact of object relations as an integrative factor is highlighted in the transference regression. The incorporation of the analyst corresponds to the acquiring and synthesis of introjects in the infant, but the reaction to the introject is multidimensional and all stages of development contribute to it.
