AF–MATB task overall, lights, dials, and system monitoring throughput capacity as a change from 1600. a Throughput capacity on all subtasks of the AF–MATB as a change from 1600. b Throughput capacity on the lights subtask of the AF–MATB as a change from 1600. c Throughput capacity on the dials subtask of the AF–MATB as a change from 1600. d Throughput capacity on the system monitoring subtask of the AF–MATB as a change from 1600. Error bars on a–d are mean + /− SE.
