Facial feedback hypothese focuses on whether the facial muscles affect the humor ratings. Before the test, students are told to put the pens in mouths but to hold them in different ways. One way is hold it with lips, another is biting the pen horizontally with the teeth. For this research, independent variable is facial expression and how funny students thought the cartoon is. Dependent variable is the extent of the humor.
The facial feedback hypothesis claims relevant facial movement can influence
emotional experience. The students who is biting the pens horizontally are
actually forced to use face muscles that they might use to smile. While holding the pens with lips, this would
prevent to use the smiling miscles, which might affect the humor ratings. Indeed, most emotions
are associated with some facial expressions. However, we cannot
just simply conclude that making some relevant smiling faces will cause the different ratings of humors. The
relationship between the facial expressions and emotions is not causation but correlation.
There may be some other rival elements that will influence the humor ratings. For
example, when we are doing this experiment with a group of people, we may be influenced by other
students. Because they may laugh before you which might make you laugh even you don't think the cartoon is funny. Besides, as a international student, there is some cartoons I cannot understand, I will just choose zero no matter what kind of facial expression I am. So I would suggest the research group can just set a rule that this research just allows american or change the content of the text into multiple languages.
