CVLT-II Scores and Descriptions
| Score | Description |
|---|---|
| List A Trial N | Number of words recalled following the Nth exposure to List A, where N=1 to 5 |
| List A Trials 1–5 | Total number of words recalled across all 5 List A exposure trials |
| List B | Number of words recalled following exposure to List B, the “interference list” |
| Short-Delay Free Recall (SDFR) | Immediately after List B recall, number of List A words recalled (List A is not read again for this trial or for the remainder of the test) |
| Short-Delay Cued Recall (SDCR) | Immediately after SDFR, number of List A words recalled when the subject is provided with each of the four semantic categories (furniture, vegetables, ways of traveling, animals) for List A as cues |
| Long-Delay Free Recall (LDFR) | Following a 20-minute delay after SDCR, number of List A words recalled |
| Long-Delay Cued Recall (LDCR) | Immediately after LDFR, number of List A words recalled when the subject is provided with each of the four semantic categories (furniture, vegetables, ways of traveling, animals) for List A as cues |
| Long-Delay Recognition | Immediately after LDCR, percentage of words identified accurately as List A words from a list of 48 words (16 List A words, 16 List B words, and 16 distractor words) |
| Primacy Recall | Percentage of the first four words on the list that are recalled on a trial or set of trials (note that this measure differs from the method of calculating Primacy Recall in the CVLT-II manual) |
| Pre-recency Recall | Percentage of the middle 8 words on the list that are recalled on a trial or set of trials |
| Recency Recall | Percentage of the last four words on the list that are recalled on a trial or set of trials (note that this differs from the method of calculating Recency Recall in the CVLT-II manual) |
| Serial Clustering | Chance adjusted score for recall clustering based on serial order, obtained by taking the difference between observed number of words recalled in the same serial order as presented and the the number of words that would be recalled in the same serial order as presented by chance alone |
| Semantic Clustering | Chance-adjusted score for recall clustering based on semantic category, obtained by taking the difference between observed number of words from the same semantic category recalled by the subject in serial contiguity and the expected number of words from the same semantic category that would occur in serial contiguity by chance alone |
| Subjective Clustering | When subject uses the same unique idiosyncratic clustering strategy in free recall across trials following each list presentation. |
| Intrusions | Words recalled by the subject that were not part of the target list |
| Perseverations (Repetitions) | Words repeated by the subject in response to the same trial |
