Stage theories, like Piaget's, propose that cognitive development occurs in qualitatively distinct stages, with each stage representing a different level of cognitive functioning. Continuity theories, however, view cognitive development as a continuous process without distinct stages, emphasising gradual and incremental changes. Both theories have their strengths and limitations. While stage theories provide a structured framework for understanding cognitive development, continuity theories acknowledge the ongoing nature of development and the interconnectedness of different cognitive abilities. Ultimately, both theories are important for understanding cognitive development, and their appropriateness depends on the specific aspects being studied.
