Figure 1

Visual progress display presented during neuroimaging rest periods. Informational display highlighting each experimental task, a progress bar and subject-identified rewards earned for completing tasks. The display was presented between imaging tasks and functioned as a supplement to researcher's instructions and verbal praise/encouragement for participation. Tasks are listed by imaging runs, such that those requiring multiple runs are listed multiple times. Task-paired rewards, listed as 'prizes,' were identified prior to neuroimaging using a preference assessment procedure and were earned contingent upon task completion, regardless of performance accuracy. The progress bar descended after a task was completed.
