Final answer:
Multidimensional development refers to how development occurs in different areas simultaneously. It includes the idea that development can be continuous, with gradual improvements, or discontinuous, occurring in distinct stages. This complexity is studied across physical, cognitive, and psychosocial domains. Option 3.
Step-by-step explanation:
Multidimensional development means that development occurs in many different areas at the same time (option 3). In the field of developmental psychology, this concept is explored with various theories that investigate whether development is continuous or discontinuous, follows a universal course or multiple unique courses, and the influence of nature versus nurture. The continuous development view posits that development is a cumulative process, characterized by gradual improvements on existing skills. In contrast, discontinuous development suggests that changes occur in distinct stages at specific times or ages, such as sudden cognitive leaps during infancy. Developmental psychologists study these changes across three domains: physical, cognitive, and psychosocial development. Moreover, the lifespan theories suggest that different stages of development, paralleling concepts like Erikson's stages, encompass prenatal, infant, child, adolescent, and adult development, emphasizing the complexity and varied timing of developmental events.
