Option 2 : Proximodistal
Development refers to an increase in structure for better and enhanced functioning of organs. A child develops in an orderly sequence which is almost similar in all children.
- The rate and speed of development may vary in individual cases but the sequence of development patterns is almost the same in all children. Thus human development is based on certain principles.
Child development takes place in two directions, one is from the head-to-foot direction and the second is from near to distant (center of the body to the peripheral).
Sequential pattern of development can be seen in two directions:
- Cephalo-caudal sequence: It means that development spreads over the body from head to foot, i.e. individual begins to grow from head region downwards.
- For example, The child first gains control on her head, then she could catch hold of objects, sit, crawl, and later she could stand and walk.
- Proximodistal sequence: It means that the development proceeds from the central part of the body towards the peripheries. In this sequence, the spinal cord of the individual develops first, and then outward development takes place.
- For example, the child could use her arms before her hands and use her hands before she could control the movement of her fingers.
- Children learn to grasp large things with hands before learning to pick up a pea using a pincer grasp.
Thus, it is concluded that the above-mentioned situation illustrates the proximo-distal principle.
