Answer: Frame of reference
Explanation: A frame of reference could be referred to a set of ideas, assumption, schemas, values or belief on which an individual's decision, understanding or judgement is based. The frame of reference might introduces bias into an individual's understanding or judgement as the frame of reference differs from person to person. This might introduce a sort of bias into a person's concept of understanding by giving or creating meaning to our perception.
Frame of reference could yield breakdown in communication due to differences in belief, experience, assumptions or background of individuals thus, resulting in differences in encoding and interpretation of messages, stimulus or perception.
