Note. This table displays the trials that were presented in each phase of the study. For each type of relation (e.g., A→B, A→C) participants began MTS training with stimuli from Sets 1 and 2. Following mastery, participants completed training with Sets 3 and 4 followed by a phase with all four sets of stimuli presented (see Figure 1 for description of the stimuli).
