Task Switching

Each card shows a letter and a number. A cue tells you the rule: number (odd or even) or letter (vowel or consonant). Sometimes the rule stays. Sometimes it flips. The flip is the test. Score is correct answers minus errors in the time window.

Task Switching

Each card shows a letter and a number. A cue tells you the rule: number (odd or even) or letter (vowel or consonant). Sometimes the rule stays. Sometimes it flips. The flip is the test. Score is correct answers minus errors in the time window.

Each card has a letter and a number. The cue says which rule to use. It sometimes flips.

Pick a length

Short is a quick check. Long is the full run. Your best for each is stored on this device.

What this measures

Task switching measures how much you pay to abandon one rule and load another. Stay trials are cheaper. Switch trials cost time and errors, the switch cost. That cost shows up when a chat ping forces you off a spreadsheet and back again. We mix stay and switch so you cannot park on one rule. Long runs show whether the cost grows as you tire. Short runs still contain enough flips to score.

Where this shows up in real life

A chat ping that forces you off a spreadsheet and back again is a switch cost. Shrinking that cost is why this drill exists.

How to improve

  • Read the cue first, then the pair. The pair without the cue is a trap.
  • Use the same two fingers for the two answers so the mapping stays stable.
  • On a switch, pause one beat. The pause is cheaper than a wrong tap.
  • Say the rule in one word: number, or letter. Keep it that short.

Frequently asked questions

What is a good switching score?

Around 20 points is typical on Long. High 20s means you keep accuracy on the flips, not only the stay trials.

Why do I feel slower after a flip?

That delay is the switch cost. It is supposed to be there. Training shrinks it. It does not vanish.

Is this the same as Trail Making B?

Same family. Trails alternate two ordered lists. This page alternates two classification rules on fresh cards.
