Abstract
Auditory verbal learning and memory was assessed in 18 patients with moderate-severe closed-head injury (CHI). Compared to a matched control group, performance of the CHI subjects on all measures of the Auditory Verbal Learning Test (AVLT) was significantly worse. Discriminant function analysis correctly classified 90% of subjects as CHI or control using the three most reliable measures of the AVLT. Retention of the learning list following the distractor trial varied with severity of injury as indexed by duration of post-traumatic amnesia (PTA). The more severe the injury (longer PTA), the fewer words were recalled after interference (r= −0–72). Susceptibility of verbal memory to retroactive interference is sensitive to the presence and severity of CHI.Keywords
