I did social cognition. Specifically where I observed my family members to see if they would mirror my behavior at dinner. But to narrow it down I chose to take a sip of my drink to see if they would as well. In the many times a tried this, I did not notice them copy my behavior once. I even would purposely mirror them when they would take a sip of their drinkś and still, they would not mirror me back which I thought was interesting. 

What is one third variable (confounding variable) that was not accounted for in the experiment?
Can this experiment be generalized to other people in the same testing group? (Other teenagers, other adults / parents etc)  Why?
