Final answer:
The concept of human nature in naturalistic assumptions about existence is chiefly linked to behavioral determinism, implying that behavior is influenced by both genetic predispositions and environmental conditioning.
Step-by-step explanation:
The concept of human nature primarily relates to behavioral determinism in naturalistic assumptions about existence and man. This view suggests that human behaviors are the result of inherited genetic patterns and physical drives, as well as prior experiences, such as conditioning and learned behaviors. Factors like innate sucking in newborns, hunger, thirst, and complex social behaviors suggest that there's an interplay between innate tendencies and environmental influences, particularly cultural pressures, which help shape social behavior and criteria for social approval.
Cognitive psychology, which focuses on human thinking, and social psychology, which studies the impact of situational factors, both contribute to understanding human behavior. The theory that individuals seek congruence between their self-perception and actions adds another layer to the understanding of human behavior. Moreover, temperament, or inborn personality differences, also plays a crucial role in individual behavioral patterns.
