Do recognition-free recall discrepancies detect retrieval deficits in closed-head injury? An exploratory analysis with the California verbal learning test.

The present study examined the validity of the Recognition Discriminability-Long Delay Free Recall discrepancy from the California Verbal Learning Test (CVLT) as a sign of retrieval deficits in closed-head injury (CHI). Discrepancy and nondiscrepancy groups who differed in their Recognition Discriminability performance but were equated on Long-Delay Free Recall were compared on indices hypothesized to reveal performance patterns consistent with retrieval deficits. Results showed that the discrepancy group produced fewer intrusions. The two groups did not differ in their consistency of recall or relative degree of benefit from semantic cuing. Additional analysis using a discrepancy group with normal Recognition Discriminability scores but abnormal Long-Delay Free Recall performance did not alter these results. The hypotheses were not supported when patients with language deficits were excluded. The findings did not support the use of this discrepancy from the CVLT as a marker for retrieval deficits in CHI.

The clinical utility of the Hopkins Verbal Learning Test as a screening test for mild dementia.

OBJECTIVE: The purpose of this study was to determine whether the Hopkins Verbal Learning Test (HVLT) could be used as a valid and reliable screening test for mild dementia in older people, and to compare its performance to that of the Mini-Mental State Examination (MMSE). METHOD: Using a cross-sectional design, we studied three groups of older subjects recruited from a district geriatric psychiatry service: (1) 26 patients with DSM-IV dementia and MMSE scores of 18 or better; (2) 15 patients with psychiatric diagnoses other than dementia; and (3) 15 normal controls. The relationship of each potential cutting point on the HVLT and the MMSE was examined against the independently ascertained DSM-IV diagnoses of dementia using a Receiver Operating Characteristic (ROC) analysis. RESULTS: The subjects consisted of 21 (37.5%) males and 35 (62.5%) females with a mean age of 74.7 (SD 6.1) years and a mean of 8.5 (SD 1.8) years of formal education. ROC analysis indicated that the optimal cutting point for detecting mild dementia in this group of subjects using the HVLT was 18/19 (sensitivity=0.96, specificity=0.80) and using the MMSE was 25/26 (sensitivity=0.88, specificity=0.93). CONCLUSIONS: The HVLT can be recommended as a valid and reliable screening test for mild dementia and as an adjunct in the clinical assessment of older people. The HVLT had better sensitivity than the MMSE in detecting patients with mild dementia, whereas the MMSE had better specificity.

Deception strategies in children: examination of forced choice recognition and verbal learning and memory techniques.

Thirty-five children ages 6-12 years were asked to complete two alternate forms of the Hopkins Verbal Learning Test-Revised (HVLT-R), once with the instruction to feign cognitive impairment and once instructed to do their best. They were also asked to complete the Test of Memory Malingering (TOMM). Regardless of condition, children performed comparably to adult norms on the TOMM, obtaining a score of 45 or above on Trial 2. Regarding the HVLT-R, differences emerged only when children were initially told to "do their best," followed by a subsequent trial in which they were told feign impairment. Within this group of participants, children demonstrated significantly lower levels of learning across trials and fewer words recalled in comparison to when they were instructed to do their best. In contrast, no reliable differences on the HVLT-R were observed among children who were initially told to feign impairment and subsequently told to do their best. These results suggest that the elicitation of "feigned" impairment within this age group on the HVLT-R requires the initial provision of an opportunity for optimal performance.
