Use of schema

Schema is a mental framework that represents some aspect of the world. Schemas can be used for objects, others, and even about yourself. Schema is like a list of things we know from past experiences. For example, when we look at a chair, we compare what we know to what we see, so we can label it as a chair. But if it is a weird looking chair with only 2 legs, we modify our list to accommodate the difference. As we grow up, we develop our list of understanding and we start to compare and adjust to objects we have never seen before but of course, it's different for a child as they have no reference to new objects. An example for adults can be simply trying to take a shower in a different bathroom. We know how to turn the water on but sometimes we experience a difficult time trying to figure out how to use the damn thing. We already have schemas around this problem as we can identify what it is and how it operates but when our schemas don't work, we start to collect other informations like how to turn on a faucet etc. The moment we figure out how to use the shower, we add the instruction to our list (schema).
