We develop schemas about the different types of real life situations that we encounter one of the more prominent theories in this domain has focused on schemas about the sequences of events that occur in different situations. Scripts allow us to make a series of inferences about the sequence of events that raise in daily situations so that we know how to act in any given situation. These scripts operate a the unconscious level in guiding our behaviour. We follow them without consciously knowing we are doing so. Essential elements of schemas are that (1) common situations have consistent attributes, (2) people have specific roles. Sometimes our schemas can lead to distortions in memory. For most part they help us interact with external world efficiently within the situational context. Schemas and scripts can sometimes have unintended consequences, such as reinforcing sexist or racist belief. What we view as appropriate is shaped by culture.
