Final answer:

Raymond Cattell is known for developing the 16 Personality Factors (16PF) questionnaire, which marked a significant advancement in quantitatively assessing and understanding personality traits.

Step-by-step explanation:

Raymond Cattell advanced the study of personality by developing the 16 Personality Factors (16PF) questionnaire. He used factor analysis to reduce prevalent personality traits to 16 primary factors, each representing a dimension along which individuals can vary. This was a significant progression in the quantitative study of personality. Instead of a trait being present or absent, Cattell scored each trait along a continuum, such as how 'warmth' might be expressed in a person's interactions ranging from distant and cold to supportive and comforting.

Cattell's work offered a nuanced view of personality, emphasizing a spectrum of traits rather than binary categorization. The 16PF questionnaire measures traits such as warmth, reasoning, emotional stability, dominance, and more.
