| Abstract: | Cognitive offloading research typically assumes uniform effects across users, yet individual differences in metacognitive awareness may influence these effects differently. We examined how users’ everyday spell-checking practices interact with their metacogni-tive awareness. Using a behavioral measure of awareness (proportion of errors detected and corrected), we conducted a 2×2 experiment (awareness × tool usage, n=88). Participants completed a three-phase spelling task.baseline, error review, and validation.with performance assessed by the number of spelling errors. Results revealed a significant interaction effect (F(1, 84) = 3.950, p = .050, η2 = .045): spell-checking tools minimally affected high-awareness users but resulted in significantly poorer performance among low-awareness users (M = 1.70 vs. M = 7.74, d = 1.07). These findings suggest that cognitive offloading tools may have differential effects depending on users’ metacognitive capabilities, raising considerations for incorporating individual differences into assistive technology design and questioning one-size-fits-all design assumptions. |
