Introduction “Our perceptions are determined by a  combination of automatic processes that  begin with the properties of the stimulus,  and individualistic processes that depend  on the person’s past experiences,  knowledge and expectations.”    E.  Goldstein (2007) In other words, we are hypothesis testing—we  do not perceive in an automatic nonthinking  way.
