When a psychologist claims that experience and learning are key elements in initiating developmental changes the psychologist most likely supports which theories of development?

When a psychologist emphasizes the importance of experience and learning in initiating developmental changes, they are likely supporting behavioral and cognitive development theories. Behavioral theories, like those proposed by B.F. Skinner and Albert Bandura, focus on how environment and experiences shape behavior through reinforcement and observational learning. Cognitive development theories, such as those by Jean Piaget and Lev Vygotsky, highlight the role of social interactions and experiences in shaping cognitive abilities and understanding.
