Edith F. Kaplan (February 16, 1924 – September 3, 2009) was an American psychologist. She was a pioneer of neuropsychological tests and did most of her work at the Boston VA Hospital. Kaplan is known for her promotion of clinical neuropsychology as a specialty area in psychology. She examined brain-behavioral relationships in aphasia, apraxia, developmental issues in clinical neuropsychology, as well as normal and abnormal aging. Kaplan helped develop a new method of assessing brain function with neuropsychological assessment, called the "Boston Process Approach."
Kaplan was a Professor in the departments of Neurology and Psychiatry, and in the Behavioral Neuroscience PhD Program at Boston University School of Medicine at the time of her death. Kaplan was also Professor of Psychology at Suffolk University and Affiliate Professor of Psychology at Clark University. She was also a member of the Psychology Department at the Baycrest Hospital in Toronto, Ontario, Canada.
Kaplan was a leader in developing education and training of neuropsychologists. From 1976 to 1987, Kaplan was the director of Clinical Neuropsychological Services at the Boston Veterans Administration Medical Center where she was responsible for the development of pre- and post-doctoral clinical neuropsychological internship training program. Later, at Suffolk University, Boston University School of Medicine, and Tewksbury Hospital, she continued this work. She also did philanthropic work with the National Head Injury Foundation and the World Health Organization.
Kaplan made important contributions to clinical neuropsychological assessment. Her observations and assessment methods evolved into a philosophical school of neuropsychological assessment, called by most people the "Boston Process Approach." Kaplan also re-purposed intelligence tests such as the Wechsler Adult Intelligence Scale as tools to localize functional deficits in the brain (whether developmental or due to lesions).
Prior to the introduction of the process-oriented approach, clinical neuropsychological assessment followed a fixed-battery global-achievement approach, and stressed quantitative interpretation of test results (for example the Halstead-Reitan battery). The process-oriented approach offered advances in test interpretation, stressing the qualitative aspects of patients' performance profiles. The Boston Process Approach examines the qualitative process by which the patient solves a problem rather than simply looking at the patient's quantitative numerical scores. The Boston Process also tailors which tests to give a patient instead of administering an entire test battery to every subject, regardless of their condition. This alternative approach improved clinical understanding of brain functions and generated discussion about diagnostic issues in clinical neuropsychology.
Kaplan developed and co-authored The Boston Diagnostic Aphasia Examination, The Boston Naming Test, The Boston Stimulus Board, The California Verbal Learning Test (Adult and Children's Versions), Microcog: A Computerized Assessment of Cognitive Status, the Wechsler Adult Intelligence Scale - Revised, as a Neuropsychological Instrument (WAIS-RNI), the Wechsler Intelligence Scale for Children - III, as a Neuropsychological Instrument (WISC-IIINI), The Baycrest Assessment of Neuropsychological Status, and The Delis-Kaplan Executive Function System (D-KEFS), a refined and expanded selection of tasks from the widely used Halstead-Reitan battery. She also contributed analytical methods for clock drawings as neuropsychological assessment tools, especially in regards to spatial neglect and attention.
Kaplan also contributed a body of research, including (with Norman Geschwind) the first paper on cerebral disconnection syndrome. She also investigated Parkinson's disease, schizophrenia, dementia, and other neuropsychological disorders.
Kaplan was one of the founders of the American Board of Clinical Neuropsychology and was among the first to be awarded the Diplomat in Clinical Neuropsychology. Kaplan was president of the International Neuropsychological Society, president of the Clinical Neuropsychology Division of the American Psychological Association (Division 40), and president of the Boston Neuropsychological Foundation, which she co-founded in 1983.
She received many awards, including The National Academy of Neuropsychology Distinguished Clinical Neuropsychologist Award in 1993, The Edith Kaplan Neuroscience Scholarship Fund in 1994, and The New England Psychological Association first annual Distinguished Contributions Award in 1996. She also won The Massachusetts Psychological Association Career Contribution Award in 1998 and The Massachusetts Neuropsychological Society Career Contribution Award in 1999.
