Final answer:
Intelligence is not one of Cattell's 16 factors of personality in his 16PF questionnaire, as his model includes factors like warmth and social boldness, but not intelligence.
Step-by-step explanation:
The question is about identifying which of the following is not one of Cattell's 16 factors or dimensions of personality. Raymond Cattell's personality theory identified 16 personality factors, which includes dimensions such as warmth, reasoning, emotional stability, dominance, and openness to change, but does not specifically include intelligence as a named factor. Intelligence is therefore the correct answer as it is not one of Cattell's 16 personality factors. These factors were meant to capture a wide range of human personality traits in his tool called the 16PF (Personality Factor questionnaire).
In contrast, the Five Factor Model, or the Big Five, includes factors such as openness (often confused with Cattell's openness to change), conscientiousness, extraversion, agreeableness, and neuroticism. These are often remembered by the acronym OCEAN. Notably, intelligence does not appear as a factor in this model either.
