OBJECTIVE: Multi-trial memory tests are widely used in research and clinical practice because they allow for assessing different aspects of memory and learning in a single comprehensive test procedure. However, the use of multi-trial memory tests also raises some key data analysis issues. Indeed, the different trial scores are typically all correlated, and this correlation has to be properly accounted for in the statistical analyses. In the present paper, the focus is on the setting where normative data have to be established for multi-trial memory tests...

OBJECTIVE: Schizophrenia is characterized by hallucinations, delusions, disorganized speech and behavior, and other symptoms that cause social or occupational dysfunction. However, some of these symptoms, such as hallucinations and delusions, can be indicative of other phenomena such as synesthesia and savant abilities. The aim of this paper is to highlight how neurological and psychiatric conditions can be confused and how formal neuropsychological evaluations can be necessary to distinguish them...

OBJECTIVE: Excessive Decline from Premorbid Functioning (EDPF) is presented as a construct and defined as a discrepancy between predicted premorbid ability and current test performance that is so atypical of individuals with true neurocognitive impairment that it is likely the product of performance invalidity. New embedded PVTs (EDPF-FSIQ, EDPF-VW, and EDPF-PP) were derived by comparing scores from the WAIS-IV to TOPF demographically predicted premorbid estimates and then examined for classification accuracy...

OBJECTIVE: While recognition memory has been the primary tool for the assessment of performance validity in neuropsychological evaluations, some consideration has also been given to embedded measures from other cognitive domains, including processing speed. The present study evaluated the classification accuracy of several speed-based measures in a Veterans Affairs Medical Center Polytrauma sample. METHOD: The present sample consisted of 114 military veterans (Mean age = 35...

OBJECTIVE: Given the hazards of knowledge about performance validity tests (PVTs) being proliferated among the general public, there is a continuous need to develop new PVTs. The purpose of these studies was to validate the newly developed Visual Association Test-Extended (VAT-E). METHOD: The VAT-E consists of 24 pairs of line drawings; it is partly based on Green's Word Memory Test (WMT) paradigm. In study 1, we compared VAT-E total scores of healthy controls (n = 226), patients with mild cognitive impairment (MCI) (n = 76), patients with Alzheimer's disease (AD) (n = 26), and persons instructed to feign memory deficit (n = 29)...

OBJECTIVE: The present study evaluated strategies used by healthy adults coached to simulate traumatic brain injury (TBI) during neuropsychological evaluation. METHOD: Healthy adults (n = 58) were coached to simulate TBI while completing a test battery consisting of multiple performance validity tests (PVTs), neuropsychological tests, a self-report scale of functional independence, and a debriefing survey about strategies used to feign TBI. RESULTS: "Successful" simulators (n = 16) were classified as participants who failed 0 or 1 PVT and also scored as impaired on one or more neuropsychological index...

OBJECTIVE: There is increasing recognition that socio-cognitive skills, such as moral reasoning (MR), are affected in a wide range of developmental and neuropsychological conditions. However, the lack of appropriate measures available to neuropsychologists poses a challenge for the direct assessment of these skills. This study sought to explore age-related changes in MR using an innovative visual tool and examine the developmental sensitivity of the task. METHOD: To address some of the methodological limitations of traditional measures of MR, a novel, visual task, the Socio-Moral Reasoning Aptitude Level (So-Moral), was used to evaluate MR in 216 healthy participants aged 6-20 years...

OBJECTIVE: Computerized tests have increasingly garnered interest for assessing cognitive functioning due to their potential logistical and financial advantages over traditional 'pencil and-paper' neuropsychological tests. However, psychometric information is necessary to guide decisions about their clinical and research utility with varied populations. We explored the convergent construct validity and criterion validity of the CogState computerized tests in breast cancer survivors, a group known to present with mostly mild, subtle cognitive dysfunction...

Andrew Gelman, Hilde M Geurts
There is currently increased attention to the statistical (and replication) crisis in science. Biomedicine and social psychology have been at the heart of this crisis, but similar problems are evident in a wide range of fields. We discuss three examples of replication challenges from the field of social psychology and some proposed solutions, and then consider the applicability of these ideas to clinical neuropsychology. In addition to procedural developments such as preregistration and open data and criticism, we recommend that data be collected and analyzed with more recognition that each new study is a part of a learning process...

OBJECTIVE: A 71-year-old (MN) with an 11-year history of left onset tremor diagnosed as Parkinson's disease (PD) completed longitudinal brain magnetic resonance imaging (MRI) and neuropsychological testing. MRI scans showed an asymmetric caudate nucleus (right < left volume). We describe this asymmetry at baseline and the progression over time relative to other subcortical gray, frontal white matter, and cortical gray matter regions of interest. Isolated structural changes are compared to MN's cognitive profiles...
