AP PSYCHOLOGY

Detailed explanation-1: -crawl. Moving by pulling with the arms, but not lifting the abdomen from the floor.

Detailed explanation-2: -What is scooting? Scooting is one (adorable) way some babies get around when they first start moving independently. It’s a prelude to traditional crawling for some babies, but others prefer scooting to get around and may stick with it until they’re ready to start pulling up and try walking.

Detailed explanation-3: -What is the difference between ‘crawling’ and ‘creeping’? Your babies are ‘crawling’ when they move around using the commando style tummy crawl. ‘Creeping’ begins when they lift their tummies off the floor and move around on their hands and knees.

Detailed explanation-4: -The cephalocaudal trend acknowledges a top-down growth trend. For example, infants may use their upper limbs before their lower limbs. The proximodistal trend, on the other hand, acknowledges growth from the center of the body outwards. For example, infants use their arms before they can use their fingers effectively.
