Gestalt Effect And Schema Theories


1)    Name three laws of Gestalt Theory and provide examples to illustrate your point.


Answers: 


According to Breidbach (2006), "Gestalt is the invariants of a collection of patterns that can mutually be transformed into each other through a class of transformations encoded by or conversely determining that Gestalt".


1. First law is Proximity

       It means fixation of eyes. According to Dr Chris Woo's lecture, objects near each other are naturally grouped together. For example, a media student was searching for books about semiotic. Previously, he had been borrowed a book from the related field. He already had an idea on how to search for books for his course. Media books are grouped together in one corner of shelf. In other words, our eyes are fixed to something that have a connection between each other.




2. Second law is Pregnantz

      According to Chris Woo's lecture notes, pregnantz is diversity while providing the same information.  For example, look at the sample of questions below. 

  

       The two questions asking about the positives of studying Media to the population. The structure of the questions are different or diversity. However, the questions provide the same information. In exam, students are often confused with some sort of the questions given. The questions and structures are sometimes confusing which lead to a mistake. 


Another example is:                             
                        

      The two pictures above are toilet signs of men and women.  The structures of a man and woman in picture 1 are different from those in picture 2. We may see the woman in picture 1 has two legs whereas the woman in picture has one leg and look more thinner than the woman in the first picture. However, both pictures do provide the same information to the public about the location of men and women's toilet eventhough the pictures made are distinctive. 


3. The third law is closure

       According to Dr Chris Woo's lecture note, its purpose is to manipulate perception and create subtle effect. For example the picture below:



       Our first perception by looking at this picture: A straw passed through an apple. How could it possible? A straw is a flexible object. How can it passed through it?


After looking the picture for a second time, we realized that the straw was not actually passed through the apple. The straw was actually not moving. It was just staying behind the apple. 


      In conclusion, the picture above has been created in manipulating our first perception about it.
