Final answer:
In the secondary circular reactions stage, three main things happen: repetition of pleasurable actions, intentional behavior, and imitation/invention of new actions.
Step-by-step explanation:
In the secondary circular reactions stage of cognitive development, three main things happen:
- The child repeats actions or behaviors that are pleasurable or interesting to them, such as shaking a rattle or dropping objects from a high chair.
- The child starts to show signs of intentional behavior, meaning they purposefully repeat actions to achieve a specific goal. For example, they may intentionally shake the rattle to make noise.
- The child begins to imitate and invent new actions. They may imitate actions they have seen others do, or they may come up with their own actions or solutions to problems.
