Which instrument identifies 16 personality types based on four dichotomies: introversion-extroversion, sensing-intuition, thinking-feeling, judging-perceiving?

• A. CoGAT
• B. MBTI
• C. SASSI-A4
• D. GRE

Answer: (B)

The main idea here is a personality assessment that creates 16 distinct types from four opposing preferences. This tool, the Myers-Briggs Type Indicator, asks you to reflect on where you lean in each of four dichotomies: introversion versus extroversion, sensing versus intuition, thinking versus feeling, and judging versus perceiving. By selecting a preference in each pair, you’re grouped into one of 16 personality types that describe typical patterns in how you energize, take in information, make decisions, and approach the outer world. In counseling-like contexts, this helps clients understand their natural tendencies and how they might interact with others or approach problems, without claiming to measure skill or risk.

The other instruments serve different purposes. CoGAT is a cognitive abilities assessment, focusing on things like verbal and nonverbal reasoning and quantitative skills. SASSI-A4 screens for substance use risk, not personality structure. GRE assesses readiness for graduate study across verbal, quantitative, and writing tasks. None of these map people into 16 personality types based on the four dichotomies that MBTI uses.
