Final answer:
The statement regarding the incorporation of dispositional traits into the BIG FIVE framework in the 1990s is TRUE. The BIG FIVE, encapsulating openness, conscientiousness, extraversion, agreeableness, and neuroticism, is essential in personality psychology for understanding and measuring personality dimensions.
Step-by-step explanation:
The statement is TRUE. In the 1990s, the concept of dispositional traits was indeed encompassed within the BIG FIVE framework of personality traits. The BIG FIVE personality traits framework, also known as the Five Factor model, represents a widely accepted theory that delineates five broad dimensions of personality. These dimensions are openness, conscientiousness, extraversion, agreeableness, and neuroticism, which can be conveniently remembered with the mnemonic OCEAN.
The BIG FIVE factors of personality each describe a spectrum between two extremes, where individuals lie somewhere along the continuum of each factor. This model has the advantage of being applicable across different cultures and demographic groups. It also corresponds with a genetic basis for personality traits and their relative stability over the lifespan, making it a comprehensive framework for personality psychology.
Overall, trait theorists, including prominent figures like Raymond Cattell, have contributed to the evolution of our understanding of personality by moving from a vast number of potential character traits to a more manageable and quantifiable set of traits described in the BIG FIVE framework.
