Final answer:
The psychologist is using the Rorschach Inkblot Test, a projective test developed in 1921 to reveal a person's unconscious thoughts by analyzing their perceptions of inkblots.
Step-by-step explanation:
If a psychologist asks you to describe what you see in a set of ten inkblots that vary in color, shading, form, and complexity, the psychologist is using the Rorschach Inkblot Test. Developed in 1921 by Hermann Rorschach, this projective test consists of symmetrical inkblot cards that are shown to individuals to reveal their unconscious desires, fears, and struggles. The imagery that test-takers report is believed to reflect their inner thoughts and feelings.
The Rorschach Inkblot Test has been standardized using the Exner system and is effective in measuring psychological issues such as depression, psychosis, and anxiety. Unlike self-report inventories, such as the Minnesota Multiphasic Personality Inventory-2 (MMPI-2) which consists of true/false questions to provide a clinical profile, projective tests are less susceptible to intentional distortion because there is no clear 'correct' answer.
