Something’s off.A report describes experiments in which participants tried to maintain a maximum grip for 12 seconds while also viewing images. When the images came with a memory-and-judgment task, participants reportedly sustained stronger grips than when they merely watched the images; the most demanding memory condition produced the highest grip-task scores.
The odd part is that multitasking is generally expected to divide attention and impair performance. The report says the added cognitive task may instead have raised arousal, with larger pupil size occurring alongside stronger grip performance. But pupil size can also vary with tension and reward expectation, and the experiments did not directly manipulate arousal. The finding was limited to combinations of tasks said not to interfere strongly with one another—not a claim that multitasking improves performance in general.
