Classification: allows you to treat objects that appear differently as belonging together, ex. Red apples, green apples and yellow apples appear different but are still classified as apples. Seeing two people shout, we understand they are in a fight. Predicting: categorizing current experience and comparing it with similar past experiences, you can predict your current situation. Communication: words refer to some type of category or concept. Illusion of the expert: feeling that something must be easy because you are so good at it.
