Described the role of private speech an scaffolding in the cognitive development of children?

Private speech, or self-directed speech, is when children talk out loud to themselves during tasks. It plays a role in cognitive development by helping children regulate their thoughts and actions, solve problems, and communicate their understanding. Scaffolding, on the other hand, is the support provided by a more knowledgeable individual to help a child accomplish tasks beyond their current ability, promoting cognitive growth and skill development. Together, private speech and scaffolding contribute to a child's cognitive development by enhancing their problem-solving abilities and fostering independence.
