Defense Mechanisms and Projective Tests

A researcher scores 20 participants’ responses to the Rorschach inkblot test for ‘aggressive content’ on a scale of 1 to 10, yielding the following data: 3, 7, 4, 8, 3, 5, 6, 4, 7, 8, 2, 5, 6, 9, 4, 3, 5, 7, 6, 4. From a psychodynamic perspective, a high score, indicating the perception of aggression in the inkblots, is interpreted as evidence of which defense mechanism?
