Abstract Humans must weigh various factors when choosing between competing courses of action. In case eye movements, for example, a recent study demonstrated that the human oculomotor system trades off temporal costs movements against their perceptual benefits, visual search targets. Here, we compared such trade-offs different effectors. Participants were shown displays with targets and distractors from two stimulus sets. each trial, they chose which target to for, and, after finding it, discriminated feature. Targets differed in (how many target-similar shown) discrimination difficulty. rewarded or penalized based on whether target’s feature was correctly. Additionally, participants given limited time complete trials. Critically, inspected items either by only manual actions (tapping stylus tablet). Results show traded difficulty both effectors, allowing them perform close predictions an ideal observer model. However, behavioral analysis computational modelling revealed performance more strongly constrained decision-noise (what choose) sampling-noise information sample during search) than search. We conclude trade-off accuracy constitutes general mechanism optimize decision-making, regardless effector used. slow-paced are robust detrimental influence noise, fast-paced movements. New & Noteworthy trade benefits decision-making. Is this effector-specific does it constitute decision-making principle? investigated question contrasting tablet) task. found evidence costs-benefits however, compromised noise at levels
