Development of humor

I undertook some of the early work on the incongruity and resolution theory of humor, ideas that are still used in contemporary psychological and brain-imaging research. The essence of this theory is that humor results from noticing and resolving an incongruity (example below). Incongruity is defined as a surprise (defeated expectations), typically conveyed in the punchline. The theory was supported by evidence that removing a joke's resolution ruined the joke, and removing the incongruity ruined the joke even more.  A developmental finding was that understanding of incongruity emerges before understanding of resolution, explaining the young child’s fondness for material that adults would consider merely silly rather than funny.

A single, representative example of the incongruity and resolution theory is provided by the Ocean View Restaurant joke. Over the years, there have been many versions of this joke. This version is probably closest to that presented by Garrison Keillor on his radio show A Prairie Home Companion.

• On their honeymoon, a couple went to the Ocean View Restaurant because it was so romantic.
  
• On their 10th wedding anniversary, they went to the Ocean View Restaurant because they liked to dance.
  
• On their 25th wedding anniversary, they went to the Ocean View Restaurant because it had a heart-healthy menu.
  
• On their 40th anniversary, they went to the Ocean View Restaurant because it offered an early bird special.
  
• On their 50th anniversary, they went to the Ocean View Restaurant because it was wheelchair accessible.
  
• On their 60th wedding anniversary, they decided to go to the Ocean View Restaurant because they had never been there before.
