Document Summary

Dogs can be similar to each other: they are both dogs, they both bark , they have tails, drools. Important when you recognoize objects, retrieve memories, solve problems: the way in which we understand in one cognitive process is likely going to be the same way similarity operates in another cognitive process. It is a construct that is general in its approach and cognitive processes.
