Piaget's theory of cognitive development proposes that individuals move through sensorimotor stages.

The correct answer is 6 sensorimotor stages.

6 sensorimotor stages.

Explanation:

The sensorimotor stage of development according to Piaget has 6 sub-stages. These include:

Simple reflexes: In the first month of life, a neonate is capable of responding to external stimuli with innate reflex actions.Primary circular reactions: Between 1 and 4 months, intentionally repeated pleasurable actions are performed by the baby on its body.Secondary circular reactions: Between 4 and 8 months, these intentionally repeated pleasurable actions are performed not only on the baby's body but also with objects.Coordination of reactions: Occurring between 8 and 12 months, a baby now uses acquired knowledge to achieve a goal. Tertiary circular reactions:  In this stage, babies are more intentional about adaptations to certain situations. Rather than pull objects apart, they attempt putting objects back together. Early symbolic thought: In this stage, mental representations of objects are now formed.
