a. Percent accuracy. Average percent accuracy (±Standard Error of the Mean (SEM)) of Lewis and Fischer rats across 7 stable baseline sessions. Lewis rats are represented by triangles and Fischer rats are represented by circles. * indicates p < .05. b. Premature responses. Average premature responses (±SEM) of Lewis and Fischer rats across 7 stable baseline sessions. Lewis rats are represented by triangles and Fischer rats are represented by circles. + indicates p < .01; * indicates p ≤ .05; # indicates p = .05. c. Omissions. Average omissions (±SEM) of Lewis and Fischer rats across 7 stable baseline sessions. Lewis rats are represented by triangles and Fischer rats are represented by circles. + indicates p < 0.01.
