The author reviews Schafer's contributions to psychological testing, emphasizing his development of the test battery, his significant contributions to psychoanalytically oriented Rorschach interpretation, and his understanding of the complex interpersonal dynamics involved in psychological test interpretation. The author also discusses his use of Schafer's writing in his own teaching and academic work, noting that Schafer's contributions have not only provided innovative methods for examining test data, but have also promoted a respectful, humanistic, and individualized approach to the patient in testing and treatment. The author asserts that Schafer's later seminal contributions to psychoanalysis had their origins in his early career as a psychologist applying psychoanalytic ideas to testing.
