Final answer:
The Cognitive Reflection Test (CRT) measures the tendency to engage in system 1 or system 2 thinking, while inventories like the MMPI are used for clinical personality profiling.
Step-by-step explanation:
The test measures one's tendency to use system 1 or system 2 thinking is the Cognitive Reflection Test (CRT). This test assesses an individual's propensity to either react quickly and intuitively, which is classified as system 1 thinking, or respond in a more deliberative and reasoned way, known as system 2 thinking. Options such as the Minnesota Multiphasic Personality Inventory (MMPI), Myers-Briggs Type Indicator (MBTI), and Wechsler Adult Intelligence Scale (WAIS) serve different purposes. The MMPI is a self-report inventory composed of true/false questions designed to establish a clinical profile of an individual's personality. It involves the assessment and diagnosis of personality characteristics and psychopathology. To clarify, the MMPI (Option a) is a self-report inventory, not a projective test, and it employs a series of true/false questions. The WAIS is an intelligence test, not related to personality tendencies.
