Learn the rule
Choose New the first time a word appears. Choose Seen when the same word appears again. Keyboard: N and S.
Decide whether each word is new or has already appeared in this session. Track recognition errors across a short sequence, starting with 15 presentations.
Practise recognising earlier items while keeping missed words, mistaken familiarity and successful repeat recognition distinct.
This English word task depends on vocabulary, familiarity and attention. It is not a diagnosis, a general memory score or evidence of improvement on other tasks.
Use one short task to explore its specific rule, then compare matching sessions.
Choose New the first time a word appears. Choose Seen when the same word appears again. Keyboard: N and S.
Keep the same settings, input and device. Check mistakes and misses before interpreting a faster response.
Keep local numeric history or save an accepted session to your optional account. You do not need to upload private practice material.
Choose 15, 20 or 30 presentations. The default has 8 new words and 7 repeats; longer sessions have 10/10 or 15/15. The order changes each session.
Choose New or Seen within 10 seconds. A word may repeat more than once; Seen means it appeared at any earlier point in this session.
Results separate correct new-word decisions, correct repeat recognition, false alarms and missed responses. Compare English sessions with the same word-bank version.
A false alarm means a new word was marked Seen. Correct repeat recognition means an earlier word was recognised; missed responses count separately.
| Metric | Meaning |
|---|---|
| Correct decisions | Correct answers plus correctly withheld WAIT responses for Go/No-Go. Missed responses remain separate from answered errors. |
| Median answer time | Middle answer time among answered presentations. Speed is secondary to correct recognition. |
| Missed responses | Presentations that reached the deadline without the required decision. Withholding a WAIT response is correct, not a miss. |
| Interruptions | A count of pauses or hidden-tab interruptions. Keep interrupted sessions separate from clean timing comparisons. |
Try another short session later. Keep attention on whether the word appeared in this session, rather than whether it feels familiar from everyday life.

This English word task depends on vocabulary, familiarity and attention. It is not a diagnosis, a general memory score or evidence of improvement on other tasks.
The task keeps stimuli and answer order in memory for the current session. Saved history and completion reporting use allowlisted settings and numeric summaries, without the words, cue sequence or individual answers.
