Palmer states that people have ideas about how the world looks like, and they use that knowledge to figure out what things are. He did a study in 1975 to show this. In his study, people were shown groups of 4 pictures. One picture was a location, a kitchen for example. The other three pictures were one object you would find in a kitchen (bread) , and two pictures that had no ties to the kitchen (an instrument and a mailbox). This was repeated with many different places and objects. His findings showed that people found it harder to recognize the objects that had no relationship to the location.
