Social schema theory builds on and uses terminology from schema theory in cognitive psychology, which describes how ideas or "concepts" are represented in the mind and how they are categorized. According to this view, when we see or think of a concept a mental representation or schema is "activated" bringing to mind other information which is linked to the original concept by association. This activation often happens unconsciously. As a result of activating such schemas, judgements are formed which go beyond the information actually available, since many of the associations the schema evokes extend outside the given information. This may influence social cognition and behaviour regardless of whether these judgements are accurate or not. For example, if an individual is introduced as a teacher, then a "teacher schema" may be activated. Subsequently, we might associate this person with wisdom or authority, or past experiences of teachers that we remember and consider important.
