Human Factors
The situation took place as I touched down onto the runway. Directly after I touched down the aircraft sharply turned to the left; making it feel as though I had little control with the rudders in order to straighten out. The aircraft went off the side of the runway slightly; before correcting it back. I had initially believed I had a flat tire; because of the little control I was feeling with the rudder pedals. After having the aircraft inspected that did not seem to be the issue. I believe that I either accidentally partially pressed on the left brake instead of only rudder; or that my passenger may have accidentally stepped on the rudder while bracing for landing. This scenario seems most likely to me; as a sharp turn while landing would make it hard to regain control of the aircraft at the speed of landing roll. In order to prevent a recurrence; I would need to feel positively confident on my coordination while landing; and diligence on keeping clear of the brakes. Another thing I can do is to reiterate to my passenger before landing to keep hands and feet clear of the controls and pedals.
C182 pilot reported loss of directional control after landing that was probably related to the passenger depressing a rudder unintentionally.
