Social cognition researchers are interested in how new information is integrated into pre-established schemas, especially when the information contrasts with the existing schema. For example, a student may have a pre-established schema that all teachers are assertive and bossy. After encountering a teacher who is timid and shy, a social cognition researcher might be interested in how the student will integrate this new information with his/her existing teacher schema. Pre-established schemas tend to guide attention to new information, as people selectively attend to information that is consistent with the schema and ignore information that is inconsistent. This is referred to as a confirmation bias. Sometimes inconsistent information is sub-categorized and stored away as a special case, leaving the original schema intact without any alterations. This is referred to as subtyping.
