FIGURE 2.

Familiar stimuli elicit incongruency-related impairments in NoGo accuracy. Participants exhibit outcome-insensitivity when managing familiar stimuli with color-response mappings that are incongruent with their daily experiences (p < 0.001). Newly learned Go/NoGo signals evoke no significant change in NoGo accuracy regardless of color-response mapping, indicating intact goal-directed performance (p = 0.279). The differential habit expression effect across Stim_Familiarity conditions depicted here is independent from ADHD symptom severity (see Table 1 for individual difference measure contributions to habit expression). Color of bars reflects NoGo stimulus colors.
