Final answer:
The psychologist is using the Rorschach Inkblot Test, a projective test that uses inkblots to uncover unconscious psychological states.
Step-by-step explanation:
When asked 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. This is a projective test designed to reveal unconscious desires, fears, and struggles, as what the test-taker sees can be indicative of their inner psychological state. Developed by Hermann Rorschach in 1921, it has been standardized using the Exner system and is considered effective in measuring psychological issues like depression, psychosis, and anxiety.
The Thematic Apperception Test (TAT), another projective test, utilizes ambiguous pictures to encourage storytelling, thereby uncovering subconscious details about a person's social world. In contrast, the Minnesota Multiphasic Personality Inventory-2 (MMPI-2) employs a series of true/false questions and is classified as a self-report inventory, unlike the projective tests which use ambiguous stimuli.
