Patterns of verbal learning after closed head injury.

Cluster analysis of the learning trials and delayed free-recall trials of 70 patients with closed head injury on the California Verbal Learning Test (CVLT) revealed 3 distinct patterns of memory performance. The clusters differed in the amount and rate of learning, retroactive interference, and the level of delayed recall. There was a significant positive relationship between performance on the CVLT and performance on concurrent measures of attention, semantic memory, and intellectual ability.
