Final answer:
True, psychologists increasingly understand personality as involving traits, motivations, and integrative life narratives. The layered model reflects in trait theories like the Five Factor Model and humanistic approaches by theorists like Maslow and Rogers, and Freud's psychoanalytic model.
Step-by-step explanation:
True, a growing number of psychologists today conceive of personality as a multi-layered arrangement of selfhood that includes the actor's dispositional traits, the agent's motivational agenda, and the author's integrative life story. This three-tiered model echoes current understandings in personality psychology which sees our personality as a complex interplay of our consistent behavior patterns or traits (the actor), our goals and motivations (the agent), and our personal narratives that integrate our life experiences into a coherent story (the author).
Trait theorists like Gordon Allport organized personality traits into cardinal, central, and secondary traits, indicating a layered structure of personality. Also, the Big Five or the Five Factor Model, which includes dimensions of conscientiousness, agreeableness, neuroticism, openness, and extraversion, suggests that these traits cover the broad spectrum of personality.
Furthermore, humanistic psychologists such as Abraham Maslow and Carl Rogers emphasized self-actualization, congruence between one's real self and ideal self, indicating an integrative aspect to personality. And Freud's structure of the psyche with id, ego, and superego reflects the multi-layered nature of personality through different forces and dynamics within an individual.
