Increased Susceptibility

Schizophrenia spectrum patients (N = 143) and healthy controls (N = 160) were administered the Rey Auditory Verbal Learning Test (RAVLT) and tests of executive functioning to directly investigate the effects of proactive interference (PI) and retroactive interference (RI) on word list recall. It was hypothesized that by virtue of the predicted preferential association between executive functioning and RI (relative to PI), patients would demonstrate increased susceptibility to RI in their ability to recall word lists. Results indicated that patients show increased susceptibility to RI relative to PI. Furthermore, this difference appeared to be related to the frontally-mediated central executive functions that were preferentially associated with RI but not PI susceptibility.

Memory Interference

AbstractThis study investigated memory interference in amnestic mild cognitive impairment (aMCI) and normal aging. Participants were 27 young adults, 44 healthy older adults, and 15 older adults with aMCI. Memory interference was examined on the California Verbal Learning Test (CVLT) and on a modified AB-AC paradigm. Despite significant differences in memory performance on the CVLT, interference measures on this test did not distinguish individuals with aMCI and healthy older adults. The AB-AC task involved first learning a list (AB list) of 12 semantically related word pairs (e.g., knee-bone). Twenty minutes later, a second list (AC list) was learned in which the same stimulus words were paired with new response words (e.g., knee-bend). Both lists were repeated until 100% accurate recall was achieved. Finally, participants recalled the first (AB) list. Proactive interference (PI) was greater among older than younger adults, and greater still among individuals with aMCI, but the older and aMCI groups showed similar levels of retroactive interference. This study suggests that PI contributes to the memory deficits seen in aMCI and that tests sensitive to PI may assist in the early identification of aMCI. Memory interventions aimed at alleviating PI may improve memory functioning in individuals with aMCI. (JINS, 2009, 15, 83–93.)

Underlying Mechanisms

AbstractThis study investigated underlying mechanisms of the verbal memory disorder associated with chronic alcoholism. Previous investigations have suggested that alcoholics are more vulnerable to interference effects on verbal learning and memory tasks, both with respect to retroactive interference (RI) and proactive interference (PI); this was the hypothesis of the current study. Measures of RI and build-up and release from PI were administered to 31 abstinent male chronic alcoholics and 24 healthy male nonalcoholic control subjects. Alcoholics demonstrated more sensitivity to RI than controls. Additionally, alcoholics displayed a more rapid build-up of PI, although they showed normal release. An increased interference effect was found to be a component of chronic alcoholics’ verbal memory impairment and may differentiate chronic alcoholism from other disorders affecting verbal learning and memory.

Ptsd Symptoms

Impairments in declarative memory have been reported in posttraumatic stress disorder (PTSD). Fragmentation of explicit trauma-related memory has been assumed to impede the formation of a coherent memorization of the traumatic event and the integration into autobiographic memory. Together with a strong non-declarative memory that connects trauma reminders with a fear response the impairment in declarative memory is thought to be involved in the maintenance of PTSD symptoms. Fourteen PTSD patients, 14 traumatized subjects without PTSD, and 13 non-traumatized healthy controls (HC) were tested with the California Verbal Learning Test (CVLT) to assess verbal declarative memory. PTSD symptoms were assessed with the Clinician Administered PTSD Scale and depression with the Center of Epidemiological Studies Depression Scale. Several indices of the CVLT pointed to an impairment in declarative memory performance in PTSD, but not in traumatized persons without PTSD or HC. No group differences were observed if recall of memory after a time delay was set in relation to initial learning performance. In the PTSD group verbal memory performance correlated significantly with hyperarousal symptoms, after concentration difficulties were accounted for. The present study confirmed previous reports of declarative verbal memory deficits in PTSD. Extending previous results, we propose that learning rather than memory consolidation is impaired in PTSD patients. Furthermore, arousal symptoms may interfere with successful memory formation in PTSD.

Rehabilitation Potential

Summary: Dynamic assessment is a diagnostic approach in which specific interventions are integrated into assessment procedures to estimate cognitive modifiability. The study investigates the utility of this approach in persons with compelling rehabilitational needs. Samples of schizophrenic patients and of elderly with and without dementia were assessed with dynamic versions of the Wisconsin Card Sorting Test and the Auditory Verbal Learning Test. Both tests were administered by applying specific procedures of verbal mediation designed to increase performance. Results demonstrated superior predictive validity with regard to proficiency in a clinical training in schizophrenic subjects and better discrimination of nondemented and demented elderly with the help of dynamic measures compared to static test scores. Subsequent correlational analyses indicated that, for both tests, performance change following intervention is related to the processing of verbal context information. Results are discussed with respect to the concept of verbal working memory as one component of the patients' rehabilitation potential.

Learning Test

Performance on a German version of the Rey Auditory-Verbal Learning Test (AVLT) was investigated for 64 juvenile patients who were subdivided in 6 clinical groups. In addition to standard evaluation of AVLT protocols which is usually confined to items recalled correctly, an error analysis was performed. Differentiating between total errors (TE), repetition errors (RE), and misnamings (ME), substantial differences between clinical groups could be demonstrated. It is argued that error analysis of verbal memory and learning enriches the understanding of neuropsychological syndromes, and provides additional information for diagnostic and clinical use. Thus, it is possible to gain a more accurate picture so that patients can be appropriately retrained, and research into the functional causes of memory and learning disorders can be intensified.
