Simulated participant view
An executive-function task where participants alternate between different response rules across trials.
No data is recorded
A visible cue indicates which rule applies to the current central stimulus.
Useful when the study needs explicit rule-switching rather than only interference control.
Less suitable for highly frequent field sampling because instructions and cognitive load are heavier.
Use only two rules at first and keep the cue highly visible on every trial.
More demanding than flanker or go/no-go, so participant burden should be considered carefully.
