Episodic Memory - Recognition
Verbal Memory Test
Words appear one at a time. Click Seen if you've encountered the word before, New if it's your first time. Three strikes and the test ends.
Verbal Memory
You will be shown words, one at a time. If you've seen a word during the test, click SEEN. If it's a new word, click NEW.
What Verbal Memory Measures
Verbal memory is the ability to encode, retain, and retrieve words and language-based information. This test specifically measures recognition memory - Deciding whether a word was previously encountered - Which is distinct from recall (reproducing words without cues). Recognition is generally easier and more resistant to aging, making it a sensitive early indicator of memory decline.
The test taps into episodic memory, the memory system that records personally experienced events and encountered information. Episodic memory is mediated primarily by the hippocampus and surrounding medial temporal lobe structures. The three-strike failure condition introduces an element of false alarm detection - Being overconfident about "Seen" judgments leads to mistakes.
Signal Detection Theory: Reading Your Score
Every response you make falls into one of four categories. Understanding them reveals the quality of your underlying memory - Not just how cautious or bold you were.
| Response | Word Was | Outcome | What It Means |
|---|---|---|---|
| Seen → Correct | Old (seen before) | Hit | Strong memory trace - You remembered it |
| New → Wrong | Old (seen before) | Miss | Encoding or retrieval failed |
| Seen → Wrong | New (first time) | False alarm | Overconfidence or proactive interference |
| New → Correct | New (first time) | Correct rejection | Good inhibition, no false memory |
Key insight: The best verbal memory performers aren't just good at recognizing old words - They're also excellent at correctly rejecting new ones. A high score with many false alarms indicates a liberal response bias, not strong memory.

Verbal Memory Across the Lifespan
Recognition memory for words is more resistant to aging than processing speed or visuospatial memory, but it does decline. The hippocampal-dependent encoding system that supports verbal recognition shows gradual volume loss starting in the 40s, accelerating after 60.
