FIGURE 1.
Overall choice of the four RGT options shown as mean (solid line) and one standard deviation band (fill). Only sessions after 10 are shown to maximize visualization of stable choice preference, which represents approximately weeks 4–8 post-injury. There were significant Injury effects on each choice option (P1 and P2: p < 0.001; P3: p = 0.048; P4: p = 0.022) and P1 had a slight, but significant decline over time (p = 0.001). Analyses indicated substantial individual variation in choice.
