Abstract
= 127; data collected in 2023) performed a signal detection task with and without support from a diagnostic aid, where task difficulty and aid reliability varied between subjects. Analyses compared observed levels of aided performance with the predictions of an optimal strategy. Aided performance was consistently suboptimal but fell furthest from optimal when the aid was most reliable and when the task was most difficult. Costs of disuse to decision accuracy were substantial. Findings replicate and extend earlier patterns of suboptimal use, indicating that a mechanism of disuse is a failure to increase aid dependence appropriately in response to increases in aid quality or task demand.
