Part of the Thomas D. Stoker Cognitive Test Battery
What to do: A colour word will appear on screen, printed in coloured ink. Press the key for the ink colour — not the word itself.
For example, if the word RED appears in blue ink, press B.
Go as fast as you can without making too many errors. Both speed and accuracy are recorded.
60 trials in total. A new word appears the moment you press a key.
