  "summary": "Pupil size has been shown to reflect physical effort during brief, discrete motor tasks. It remains unknown whether pupil size similarly scales with effort during sustained repetitive movement, or whether it also reflects the accumulation of motor fatigability, a reduction in motor performance during prolonged movements. In our previous work, sustained maximal tapping induced motor slowing, a…",
