Randomized trials evaluate multitasking efficiency in different task conditions, suggesting metrics impact assessments.

This research aims to explore discrepancies between subjective multitasking impressions and objective performance metrics.
Conducted two experiments on multitasking efficiencies with 18 and 32 individuals respectively.
Applied a Psychological Refractory Period (PRP) paradigm in Experiment 1 with distinct tasks.
Utilized identical task sets in Experiment 2 to increase interference during overlapping dual-task conditions.
Shorter time on task (ToT) observed in overlapping dual-task conditions compared to sequential ones, N=50, indicating potential efficiency.
Minimal evidence found for compensatory effects in multitasking performance.

Jung et al. (2026) studied this question.
