AP PSYCHOLOGY

Detailed explanation-1: -The child who likes peekaboo is in the sensorimotor stage (between birth and age 2). Before the age of about 8 months, they do not understand the concept of object permanence-that is, they think if they can’t see something it isn’t actually there anymore.

Detailed explanation-2: -The sensorimotor stage is the first of the four stages of Piaget’s theory of cognitive development. It is marked by a child’s knowledge that the outside world exists separately from themselves. Once the child has fully realized this, they will move on to the next stage within Piaget’s stages of development.

Detailed explanation-3: -Stage 4. Coordination of secondary circular reactions (infants between 8 and 12 months). At this stage, infants’ behavior becomes goal-directed in trying to reach for an object or finding a hidden object indicating they have achieved object permanence.

Detailed explanation-4: -Piaget designated the first two years of an infants lifeas the sensorimotor stage. During this period, infants are busy discovering relationships betweentheir bodies and the environment. Researchers have discovered that infants haverelatively well developed sensory abilities.

Detailed explanation-5: -This is what defines the sensorimotor stage. For example, a baby might giggle or smile because he or she perceived something as funny or interesting. Giggling or smiling is an example of a reaction induced by cognitive development, so it would fall under the sensorimotor stage.
