Answer:
- Means-end behavior
- Object permanence
- A circular reaction
Step-by-step explanation:
Means-end behavior can be defined as a planned sequence of steps taken by a child to achieve their goal. in achieving this goal they face certain obstacles which they remove. They can remove these obstacles because they learned it in the previous three stages of development.
Object permanence is the stage where the child knows about the existence of the object even if they can not see it.
In the given question, Danny, who is one-year-old is expecting things to reappear which shows that he is showing object permanence.
Circular Reaction is the stage in the cognitive development of Piaget's theory in which the child starts repeating certain action.
Danny is showing this stage of development with his repeating habit of flushing.
