Short answer
Sleep loss, stress and interruptions can affect performance. They do not let us calculate an individual's “true score” by adding a fixed number of points. AurorIQ cannot diagnose a sleep or mental-health condition from a task result.
What sleep research found
Lim and Dinges’s meta-analysis examined short-term total sleep deprivation. Effects varied by task, with substantial effects on attention lapses and smaller, sometimes nonsignificant effects on reasoning accuracy. These experimental conditions should not be equated with every ordinary poor night's sleep.
Stress is not one uniform effect
Shields and colleagues’ meta-analysis found average impairments in working memory and cognitive flexibility under acute stress, with more complex findings for inhibition. Effects depended on other variables. A simple rule that a particular amount of stress always helps or harms everyone is too strong.
Using an AurorIQ result
If you were interrupted, rushing or struggling to stay alert, record that context. The result still describes the answers submitted, but does not isolate a stable ability from those conditions. AurorIQ's internal posterior-spread diagnostic does not account for all such influences, and no population confidence interval is displayed.
A retake prefers items not previously recorded as seen on this browser, but overlap and format familiarity can still contribute to a changed result. A better score on a rested day cannot tell us exactly how much was due to rest, practice or other differences.
A practical approach
Choose a time when you can follow the instructions comfortably. Reduce interruptions if possible, and stop if you do not feel able to continue. There is no need to use stimulants, change medication or sacrifice sleep to improve a practice score. This guide does not prescribe treatment.
Read the methodology limits and accuracy guide. For persistent concerns about sleep or daily functioning, a short web task is not an appropriate evaluation.
