Final answer:
Understanding the whole person in human development is crucial because development is an integrated process influenced by a combination of genetic, environmental, and social factors across physical, cognitive, and psychosocial domains. Therefore correct option is C
Step-by-step explanation:
It's essential to understand the whole person in studying human development because we function in an integrated manner. Our developmental outcomes are not just a result of external factors; they emerge from the complex interplay of genetics, environment, culture, and social relationships. The fields of psychology and sociology both emphasize the importance of early stages of development and social interaction for self-development. Development is ongoing and multidimensional, including physical, cognitive, and psychosocial development.
Developmental psychologists use various approaches to explore questions like whether development is continuous or discontinuous and how nature and nurture contribute. Socialization is a crucial component, as illustrated by theories such as those by Charles Cooley, George Mead, Lawrence Kohlberg, and Carol Gilligan. Similarly, developmental biology shows how environmental factors can affect biological development even from the womb, highlighting the importance of considering a holistic approach.
Attachment theory in psychosocial development, for example, underscores the significance of relationships in early infancy for subsequent development. Likewise, twin studies offer valuable insights into the nature versus nurture debate by comparing the development of genetically identical individuals in different environments.
