     and cultural background. 
  •  refers to the setting or environment in which a perception is made. 
   •  is the predisposition or 'readiness' to perceive something in accordance with what we 
       expect it to be. Our expectations of what an object or event will be make us more 
        likely to interpret the object or event in the predetermined way.
