Word Recognition Speed
Words flash on screen. Decide as fast as possible: is it a real word or a made-up word? Your reaction time is your score.
REAL
e.g. "table"
FAKE
e.g. "blick"
30 words · ~2 minutes
01 /How to Play
- Words and non-words will flash on screen briefly.
- Decide as fast as possible: real word (YES) or made-up word (NO).
- Reaction time is measured for each decision.
- Your average lexical decision time is your score — lower is faster.
- Speed and accuracy are both measured.
02 /The Science
Lexical decision tasks — deciding whether a letter string is a real word — are the gold standard measure of orthographic processing speed and lexical access in cognitive psychology. Response times in lexical decision tasks are highly predictive of reading fluency, verbal working memory efficiency, and crystallized intelligence. Average lexical decision RT in skilled adult readers is approximately 600-800ms. Faster access indicates more efficient mental lexicon organization and stronger orthographic representations in the left fusiform gyrus.
03 /Pro Tips
- Trust your instinct — if it feels like a word, it probably is.
- Common high-frequency words (the, run, big) will feel faster than rare words.
- Non-words that sound like words (e.g., 'blick') are harder — this is normal.
- Reading volume predicts word recognition speed — avid readers are systematically faster.
- Bilingualism can sometimes slow lexical decision due to cross-language competition.
