Final answer:
The correct statement about social development theories is that they regard development as occurring on biological and psychological levels, encompassing a lifelong process across various domains and influenced by both nature and nurture.
Step-by-step explanation:
The true statement regarding social development theories is that they consider the primary levels on which human development occurs to be biological and psychological.
Social development theories do not assume that development begins at a specific age such as five, nor do they solely focus on the transition from childhood to adulthood or on individual criminal incidents.
Instead, these theories, as studied by developmental psychologists, view development as a lifelong process across three domains which include: physical, cognitive, and psychosocial.
The influence of both nature and nurture is considered in understanding human development.
Key theorists like Sigmund Freud, Erik Erikson, and Jean Piaget have contributed to the understanding of personality and cognitive development through various life stages.
Lawrence Kohlberg, on the other hand, focused on moral development. Lev Vygotsky emphasized the sociocultural aspects of development, suggesting the critical role of one's culture and social interactions in shaping language, thought, and the developmental process.
