3.1.1. Participants

The results from the fMRI pilot motivated the design and interpretation of our fully-powered EEG experiment. Forty-four right-handed participants were recruited from the University of Oregon Human Subjects Pool (22 males, 22 females), with ages ranging between 18 and 39 years old ( *M* = 19.5, *SD* = 3.2). All of the participants had normal or corrected-to-normal vision, had no history of head trauma or seizures, and were not consuming medication that could a ffect their EEG. The participants were pre-screened online for their experience with football to reduce the chance of contextual familiarity confounding di fferences in skill acquisition rate. Only those subjects that were comfortable recognizing football defensive formations were allowed to participate. The University of Oregon and Brain Electrophysiology Laboratory Company (BELCO) institutional review boards approved the research protocol, and the study took place in the laboratory of BELCO.
