The CVLT was expanded to younger ages with the publication of the CVLT-C. It not only extended the age downward to 5, it also modified the content to be more relevant for children. The word list was shortened to 15 words derived from three semantic categories. The semantic categories reflect categories common in childhood. Two of these categories overlap with the semantic categories contained in the adult forms. Similar to the administration of the original CVLT, the child is read the list of 15 words across five learning trials, followed by an interference list trial. Just as in the original CVLT, the lists are presented as Monday and Tuesday shopping lists. Following the interference trial, the child recalls the original list in both short-delay free- and cued-recall trials. The examiner then completes nonverbal testing for 20 min before administering long-delay free- and cued-recall trials, as well as a delayed recognition trial (see Figure 1.1). All trials are required to derive the primary scores. Scores derived on the CVLT-C assess auditory attention, learning strategies and characteristics, recall accuracy and consistency, proactive and retroactive interference, recall errors, and recognition.

A T score is derived for the learning trials (Trials 1–5 Total) with a mean of 50 and a standard deviation of 10. The process scores provided in the CVLT-C provide detailed information about the learning and memory processes required to recall verbal information. For these scores, age-corrected z scores are provided with a mean of 0 and a standard deviation of 1. The scores derived in CVLT-C are listed in in Rapid Reference 1.1 by condition. Detailed information on calculating scores is provided in Chapter 3.
