Final answer:
The personality theory that accounts for the whole environment influencing a person's personality is the social-cognitive theory, which includes concepts like reciprocal determinism and the impact of culture on personality.
Step-by-step explanation:
The personality theory that considers the entire environment in which a person lives and reacts is typically referred to as the social-cognitive theory of personality. Influential psychologists like Albert Bandura have contributed to this perspective, embracing reciprocal determinism, which suggests that cognitive processes, behavior, and context all interact with each other. Within this theory, culture is an important environmental factor that shapes personality. Cultural differences influence personality traits, and the nature of individualist versus collectivist cultures affects the development of personality traits differently.Furthermore, this theory posits that we learn and develop personality through our interactions with the environment, which includes both personal experiences and cultural influences. Additionally, concepts like self-efficacy and observational learning are integral to understanding how we develop and express our personalities within the social-cognitive framework.
