The purpose of this assignment is to assess a number of key theories and issues associated with the error, particularly in relation to personal perception. Perception is a process that helps people in organizing and interpreting their sensory impressions so that they can give meaning to their environment. For example, when people are loud, attractive or unattractive, they are noticed more in a group. The context is important too. The time when the perception is made, the location, light, heat, etc. are the things that influence the perception.
