AP PSYCHOLOGY

Detailed explanation-1: -Creeping and crawling are different names for the same skill. Some children begin walking when they are one-year-old. The Palmar reflex is replaced with voluntary grasping in the first year. Differences in physical development are due to both genetic ad environmental factors.

Detailed explanation-2: -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-3: -Crawling is the action of moving the body forward with reciprocal movements of the arms and legs while the belly is on the ground. This term is commonly used for what pediatric physical therapists call “creeping.” Creeping is the act of crawling forward on hands-and-knees with the belly lifted.

Detailed explanation-4: -A good example of a fine motor skill is grabbing for a toy or object nearby.

Detailed explanation-5: -In order to crawl, a baby needs a sense of his body in space (vestibular sense), a sense of his body parts and how they work (proprioceptive sense), and muscle strength to propel movement-all of which have been developing during months of tummy time, rolling and sitting up.
