To the analyst who, like other clinicians, sometimes fails to diagnose sufficiently early certain borderline patients, Appelbaum's experience in psychological testing is relevant. He has noted that in a number of instances such patients will wait until the very last response to a test, such as the Rorschach or Word Association test, to reveal the chinks in their armor. He compares this finding to the often clinically noted fact that patients will save an important communication until the end of an hour; or, he might have added, until the late stages of treatment when termination threatens.
