In a study of twelve members of the University of Pennsylvania’s varsity soccer teams (all native English speaking), researchers found that participants called approximately three more fouls when images of soccer plays where viewed from right-to-left (66.5 fouls) compared to mirror images moving left-to-right (63.3 fouls). Participants were statistically more likely to call a foul when seeing a right-to-left attack.
