How the task works
Apply the letter rule in one position and the number rule in the other. Each position change requires you to retrieve the newly relevant rule before responding.
Rule Shift
Use the highlighted position to decide whether to apply the letter rule or the number rule.
Choose session length
Keep both rules ready as the active one changes.
Task guide and research
Task-switching game: alternate between letter and number rules
Rule Shift changes the active decision according to stimulus position. It is based on the alternating-runs task-switching paradigm rather than a personality or diagnostic test.
Research connection
Rogers and Monsell measured switch costs using letter and number classifications arranged by position. Their experiments showed that preparation reduces, but does not always remove, the cost of changing task sets.
How to interpret your result
Your score mixes rule accuracy, reading speed, and response speed. Improvement can be specific to these cues and rules and does not establish broad cognitive flexibility.
