The objective of the present study was to provide normative data for Trail Making Test (TMT) time to completion and performance errors among cognitively normal older adults, and to examine TMT error rates in conjunction with time scores for pre-clinical and clinical Alzheimer's disease (AD) diagnostic decision-making. A sample of 526 individuals was(More)
The detection of suboptimal effort has become crucial in clinical neuropsychological practice in order to make accurate diagnoses, prognoses, and referrals. Symptom Validity Testing (SVT) has been the most commonly utilized model for assessing effort, and frequently includes recognition memory tasks. Some conflicting views on this model purport, however,(More)
The presence of third parties during neuropsychological evaluations is an issue of concern for contemporary neuropsychologists. Previous studies have reported that the presence of an observer during neuropsychological testing alters the performance of individuals under evaluation. The present study sought to investigate whether audio-recording affects the(More)
It is well established that performance on the Wisconsin Card Sorting Test (WCST) tends to decline with advanced age, but the reason for this decline has not been established. The objective of the present study was to clarify this question using a qualitative approach to the task. The WCST was administered to 19 older adults and 25 younger participants. In(More)
The current study examined the effect of diagnosis threat on self-efficacy and neuropsychological performance in mild traumatic brain injury (TBI). Forty-nine participants with a history of mild TBI were randomized to a diagnosis threat or control group. The diagnosis threat group were told they were selected based on their history of TBI, while control(More)
UNLABELLED The Finger Tapping Test (FTT) and Grooved Pegboard Test (GPT) are commonly used in neuropsychological assessments. The performance of healthy older adults on these tasks has not been well characterized in the existing literature. The present study examines FTT and GPT performance in a sample of 307 community-dwelling older individuals (ages(More)
Tests of possible malingering are in increasing demand among neuropsychologists. The Test of Memory Malingering (TOMM) is resistant to many neurological conditions, including traumatic brain injury, dementia, and aphasia. Less clear is the impact of psychological conditions on TOMM performance. This study examined a sample of community-based older adults(More)
The primary goal of this study was to establish the stability of the Wide Range Achievement Test (WRAT-3) Reading score across two annual assessments of aging individuals. Participants were classified as controls (n = 200), mild cognitive impairment (MCI; n = 137), or possible or probable Alzheimer's disease (AD; n = 41). Test-retest stability was(More)
Strategies for the detection of possible malingering have largely taken two forms. First is the development and validation of domain-specific measures of malingering designed specifically for the detection of malingering (e.g., Test Of Memory Malingering, Word Memory Test, and Word Completion Memory Test). The second has been the development and evaluation(More)
Longitudinal normative data obtained from a robust elderly sample (i.e., believed to be free from neurodegenerative disease) are sparse. The purpose of the present study was to develop reliable change indices (RCIs) that can assist with interpretation of test score changes relative to a healthy sample of older adults (ages 50+). Participants were 4217(More)
