Step 1: Understanding the Question:
The question asks us to identify the projective personality tests from the given list of psychological instruments.
Step 2: Key Formula or Approach:
Projective tests are psychological assessments that present ambiguous, unstructured stimuli to a subject.
The underlying theory is that the individual will project their unconscious feelings, desires, and conflicts onto these stimuli.
Step 3: Detailed Explanation:
• Let us evaluate each instrument listed:
• A. Street Gestalt Completion Test: This is a non-verbal cognitive/perceptual test designed to measure visual closure, not a projective test.
• B. Gottschaldt Figures Test: This is a perceptual performance test used to assess cognitive style (field dependence or independence).
• C. Rorschach Inkblot Test: This is a classic, widely used projective test where individuals interpret symmetrical inkblots, projecting their internal perceptual and emotional patterns.
• D. Barron-Welsh Art scale: This is an objective visual preference scale used to measure aesthetic preference and creativity.
• E. Washington University Sentence completion test: This is a semi-structured projective test designed to measure ego development using unfinished sentence stems.
• Thus, only C (Rorschach Inkblot Test) and E (Washington University Sentence completion test) meet the criteria for projective testing.
Step 4: Final Answer:
The correct choice is C & amp; E Only, which matches Option (C).
