Cognitive Testing Group

The Cognitive Testing Group (CTG), part of the Laboratory of Behavioral Neuroscience (LBN) provides cognitive and neuropsychological testing expertise and services to the Baltimore Longitudinal Study of Aging, as well as other National Institute on Aging research projects (e.g., Exendin, GESTALT). CTG administers, scores, enters and verifies cognitive and neuropsychological tests and adjudicates data discrepancies. The measures performed are designed to assess normal cognitive aging, pre-clinical predictors of cognitive decline and dementia, specifically Alzheimer’s disease (AD) and the detection of dementia, in addition to decision making and hippocampal activation during functional magnetic resonance imaging. CTG conducts assessments of everyday functioning required for the adjudication of Mild Cognitive Impairment (MCI) and diagnosis of dementia and AD and contributes to consensus case conferencing used to assign MCI and dementia. CTG trains psychometric testers for LBN collaborators, monitors their data and conducts quality assurance to ensure that data are collected according to strict psychometric parameters. The group provides guidance on test selection based on psychometric study needs and makes suggestions for test procurement. The CTG head prepares poster presentations and manuscripts for submission and contributes cognitive testing and interpretation expertise for posters, presentations and manuscripts prepared by LBN colleagues and external collaborators.
