A complex-span working-memory task combining a rotation judgment with spatial memory storage.
Configure parameters and run an interactive preview exactly as participants will experience it. No data is recorded.
Adjust parameters below, then start the preview on the right.
Include practice trials
Shown with feedback before the main task
Task parameters
Sets run from size 2 up to this maximum (two sets per size).
Practice always runs 2 sets of size 2. Outputs: recall accuracy, processing accuracy, longest correct set (span score).
This is a researcher preview. No participant data is recorded.
Simulated participant view
A complex-span working-memory task combining a rotation judgment with spatial memory storage.
No data is recorded
Short sequences combine a processing judgment with later recall of stored spatial information.
Useful when the study specifically needs a stronger working-memory-capacity estimate than a simple span or 1-back task.
Not suitable for lightweight daily sampling because onboarding and task complexity are relatively high.
Use only after piloting participant comprehension and completion burden.
An advanced module best used selectively in studies that truly need complex span measurement.
