AP PSYCHOLOGY

Detailed explanation-1: -This developmental milestone is a primary goal of the sensorimotor stage. It’s your child’s ability to understand that objects and people continue to exist even when they can’t see them. It’s when your child starts to realize the things-and people, like you!

Detailed explanation-2: -Your baby will begin to understand the concept of object permanence when she is around 7 or 8 months old. You can tell that your baby is starting to understand object permanence if she starts looking around for a toy you’ve just hidden. Separation anxiety usually starts around this time, too.

Detailed explanation-3: -During this stage, children will discover pleasurable actions around their bodies. It occurs in the first four months of their lives. Hallmarks of this stage include wiggling their fingers, kicking their legs, or sucking their thumbs.

Detailed explanation-4: -Object permanence is a major milestone in the first of four stages-sensorimotor stage. This stage marks the period between birth and age 2. During this stage, your baby learns to experiment and explore through movement and their senses, since they don’t yet understand symbols or abstract thought.
