A young child may have an existing schema for dogs.She knows that dogs have four legs, so she might automatically believe that all animals with four legs are dogs.For example, imagine a young boy raised in a home that presents a stereotyped schema about another social group.Because of his upbringing, he might even harbor prejudices toward people in this group.l When the young man moves away to college, he suddenly finds himself surrounded by people from this group.New schemas may also be developed during this process.Consider, for example, how small children learn about different types of animals.The Accommodative IOL (intraocular lens implant) is designed to mimic the movement of the natural crystalline lens of the eye.When we are younger, the natural lens is very flexible and easily moves back and forth within the eye as we change our visual focus from up close to distance objects.
Unlike conventional “single vision” intraocular lenses (IOLs), accommodating IOLs are lens implants that are designed to help patients see at varying distances using different points of focus.
One of these methods that was described by an early psychologist is known as accommodation.
Accommodation is part of the learning process that allows us to change our existing ideas in order to take in new information.
As we age however, most commonly in our early to mid 40s, the eye loses its flexibility and can no longer easily accommodate those changes in our focus.
To imitate the action of the young natural lens, the accommodating IOLs are able to move and/or change shape inside the eye to allow focus at multiple distances.
