Step-by-step explanation:
The science of personality is a branch of psychology that focuses on understanding behavior and the underlying cognitive and physiological processes. Personality psychologists aim to identify and measure personality traits, and determine how these traits interact in different contexts to predict behavior. The field of personality psychology has evolved from early approaches like phrenology, which attempted to correlate personality with physical measurements, to a more quantitative approach that includes theories like the Five Factor model, which identifies five major dimensions of personality.
