The Effect of Smiling on Whether or Not Others Are
More Inclined to SmileBy: Andrew Brindell
Mrs. Pietrangelo’s Honors Biology
Period 3
Problem Statement and Hypothesis
Problem Statement: If I smile at a person will they be more inclined to smile immediately after?
Hypothesis: If I smile at a group of 160 strangers I have never met, then over fifty percent of them will smile back at me.
Reasoning A topic unknown by me. Appeared fairly interesting. Based on human personality and
patterns. Fascinated to see the results.
Basic Concepts -Contagiousness-
tending to spread from person to person -Inclination-
a disposition or bent, esp. of the mind or will. -Smile-
to assume a facial expression indicating pleasure, favor, or amusement, but sometimes derision or scorn, characterized by an upturning of the corners of the mouth.

Whether or Not Others Are More Inclined to Smile
Hypothesis: If I smile at a group of 160 strangers I have never met, then over fifty percent of them will smile back at me.
IV: The Amount of Times I Smiled at Strangers.
DV: The Amount of Strangers That Smiled Back.
Design Diagram (Continued)
Constants: The type of smile that I use from person to person for each level. Not knowing or having and bias of the people in the experiment. The absence of humorous instigators near by. The speed at which you walk around when conducting the experiment as defined by the procedure. The period of time that the smile is held for during the experiment. The period of which the strange is given to smile back. A similar amount of total people in the public area. The type of area that the experiment is taken place in from level to level. Locations of Smiling Trials.Materials: 1 pad of college ruled paper to record results from experiment on. 1 #2 pencil to write down the recorded results from the experiment on the pad of paper. The ability to smile to carry out the experiment and its goals A setting that will easily allow the experiment to take place (Ex. A mall or a park)

Trials 40 40 40 40
Procedure Create four charts on the pad of college ruled paper using your pencil each having two defined
sections. One for strangers that smiled back, and one for strangers that did not. They all should look something like the following:
Go to the Montgomery Mall to conduct the different levels of the experiment. Do 10 trials of “Average Smile”, 10 trials of “Slightly Exaggerated Smile”, 10 trials of “Hysterical Smile”, and 10 trials of the “Control Group”.
Slowly walk around the area that you have selected, if a stranger makes eye contact with you smile at them according to the proper level of the experiment that you are testing.
If the stranger smiles back at you put a tally in your table under the column titled “Strangers That Smiled Back”, if the stranger does not smile at you put a tally under the column titled “Strangers That Did Not Smile Back”.
Repeat steps 3 and 4 until you have a total of 40 combined tallies in the different tables on your pad of paper, 10 for each table.
Repeat steps 2 through 5 but instead of the Montgomery Mall change the location to a different location for every 40 people that you tally. Other locations include Plymouth Meeting Mall, King of Prussia Mall, and Willow Grove Mall.
Repeat steps 3 through 5 changing the levels as necessary until you have filled all the tables on your pad of paper, having each table with 40 tallies. Make sure that you are not repeating the strangers that you smile at.
Once finished analyze data to see whether your hypothesis was either supported, refuted, or neither supported nor refuted.
