Psychology is the science of mind and behavior. Psychology includes the study of conscious and unconscious phenomena, as well as feeling and thought. It is an academic discipline of immense scope. Psychologists seek an understanding of the emergent properties of brains, and all the variety of phenomena linked to those emergent properties, joining this way the broader neuro-scientific group of researchers. As a social science, it aims to understand individuals and groups by establishing general principles and researching specific cases.
Neuropsychology is a branch of psychology that is concerned with how a person's cognition and behavior are related to the brain and the rest of the nervous system. Professionals in this branch of psychology often focus on how injuries or illnesses of the brain affect cognitive and behavioral functions.
Dr. Karl H. Pribram was a professor at Georgetown University, in the United States, an emeritus professor of psychology and psychiatry at Stanford University and distinguished professor at Radford University. Board-certified as a neurosurgeon, Pribram did pioneering work on the definition of the limbic system, the relationship of the frontal cortex to the limbic system, the sensory-specific "association" cortex of the parietal and temporal lobes, and the classical motor cortex of the human brain. He worked with Karl Lashley at the Yerkes Primate Center of which he was to become director later. He was professor at Yale University for ten years and at Stanford University for thirty years.
Neuropsychological tests are specifically designed tasks that are used to measure a psychological function known to be linked to a particular brain structure or pathway. Tests are used for research into brain function and in a clinical setting for the diagnosis of deficits. They usually involve the systematic administration of clearly defined procedures in a formal environment. Neuropsychological tests are typically administered to a single person working with an examiner in a quiet office environment, free from distractions. As such, it can be argued that neuropsychological tests at times offer an estimate of a person's peak level of cognitive performance. Neuropsychological tests are a core component of the process of conducting neuropsychological assessment, along with personal, interpersonal and contextual factors.
Clinical neuropsychology is a sub-field of psychology concerned with the applied science of brain-behaviour relationships. Clinical neuropsychologists use this knowledge in the assessment, diagnosis, treatment, and or rehabilitation of patients across the lifespan with neurological, medical, neurodevelopmental and psychiatric conditions, as well as other cognitive and learning disorders. The branch of neuropsychology associated with children and young people is pediatric neuropsychology.
Neuropsychological assessment was traditionally carried out to assess the extent of impairment to a particular skill and to attempt to determine the area of the brain which may have been damaged following brain injury or neurological illness. With the advent of neuroimaging techniques, location of space-occupying lesions can now be more accurately determined through this method, so the focus has now moved on to the assessment of cognition and behaviour, including examining the effects of any brain injury or neuropathological process that a person may have experienced.
Edith F. Kaplan 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."
Muriel Deutsch Lezak is an American neuropsychologist best known for her book Neuropsychological Assessment, widely accepted as the standard in the field. Her work has centred on the research, assessment, and rehabilitation of brain injury. Dr. Lezak is Emeritus Professor of Neurology at the Oregon Health and Science University School of Medicine.
Jochen Fahrenberg is a German psychologist in the fields of Personality, psychophysiology and philosophy of science.
Raymond S. Dean was an American psychologist who was the George and Frances Ball Distinguished Professor of Neuropsychology and Professor of Psychology at Ball State University.
Pediatric neuropsychology is a sub-speciality within the field of clinical neuropsychology that studies the relationship between brain health and behaviour in children. Many pediatric neuropsychologists are involved in teaching, research, supervision, and training of undergraduate and graduate students in the field.
Thomas Hice Budzynski was an American psychologist and a pioneer in the field of biofeedback, inventing one of the first electromyographic biofeedback training systems in the mid-1960s. In the early 1970s, he developed the Twilight Learner in collaboration with John Picchiottino. The Twilight Learner was one of the first neurotherapy systems.
Common factors theory, a theory guiding some research in clinical psychology and counseling psychology, proposes that different approaches and evidence-based practices in psychotherapy and counseling share common factors that account for much of the effectiveness of a psychological treatment. This is in contrast to the view that the effectiveness of psychotherapy and counseling is best explained by specific or unique factors that are suited to treatment of particular problems. According to one review, "it is widely recognized that the debate between common and unique factors in psychotherapy represents a false dichotomy, and these factors must be integrated to maximize effectiveness". In other words, "therapists must engage in specific forms of therapy for common factors to have a medium through which to operate". Common factors is one route by which psychotherapy researchers have attempted to integrate psychotherapies.
The Halstead-Reitan Neuropsychological Test Battery (HRNB) and allied procedures is a comprehensive suite of neuropsychological tests used to assess the condition and functioning of the brain, including etiology, type, localization and lateralization of brain injury. The HRNB was first constructed by Ward C. Halstead, who was chairman of the Psychology Department at the University of Chicago, together with his doctoral student, Ralph Reitan. A major aim of administering the HRNB to patients was if possible to lateralize a lesion to either the left or right cerebral hemisphere by comparing the functioning on the both sides of the body on a variety of tests such as the Suppression or Sensory Imperception Test, the Finger Agnosia Test, Finger Tip Writing, the Finger Tapping Test, and the Tactual Performance Test. One difficulty with the HRNB was its excessive administration time. In particular, administration of the Halstead Category Test was lengthy, so subsequent attempts were made to construct reliable and valid short-forms.
William T. "Bill" O'Donohue is an American psychologist who focuses on human sexuality, especially child sexual abuse. In 2009 O'Donohue was appointed as advisor to the DSM-V Work Group on Sexual and Gender Identity Disorders of the American Psychiatric Association.
The Division of Clinical Neuropsychology of the American Psychological Association is a scientific and professional organization of psychologists interested in neuropsychology and clinical neuropsychology, the study of brain-behavior relationships with a focus on applying this knowledge to human problems. The Division of Clinical Neuropsychology was established as a specialty organization within APA in 1980 and was formally recognized by APA in 1996 via the Committee for the Recognition of Specialties and Proficiencies in Professional Psychology". It has become one of APA's largest and most active divisions with over 4200 members worldwide. The Division of Clinical Neuropsychology has been instrumental in the development of clinical neuropsychology as a psychological specialty. This organization helped to establish policies and standards for practice and training in clinical neuropsychology as well as developed the definition of a clinical neuropsychologist, which has been used as a foundation by other neuropsychological organizations.
Gerald Paul Koocher is an American psychologist and past president of the American Psychological Association (APA). His interests include ethics, clinical child psychology and the study of scientific misconduct. He is Dean Emeritus Simmons College and also holds an academic appointment at Harvard Medical School. Koocher has over 300 publications including 16 books and has edited three scholarly journals including Ethics & Behavior which he founded. Koocher was mentioned in the Hoffman Report, an APA investigation into psychologists' involvement in interrogation at Guantanamo Bay, Cuba.
Vittorio Filippo Guidano was an Italian neuropsychiatrist, creator of the cognitive procedural systemic model and contributor to post-rationalist constructivist cognitive psychotherapy. His cognitive post-rationalist model was influenced by attachment theory, evolutionary epistemology, complex systems theory, and the prevalence of abstract mental processes proposed by Friedrich Hayek. Guidano conceived the personal system as a self-organized entity, in constant development.
Alfredo Ardila is a Colombian neuropsychologist living in Miami, USA. He graduated as a psychologist from the National University of Colombia and received a doctoral degree in neuropsychology from the Moscow State University where he was working with Alexander R. Luria. He has published in cognitive and behavioral neurosciences, especially in neuropsychology.
Developmental neuropsychology combines the fields of neuroscience and developmental psychology, while drawing from various other related disciplines. It examines the relationship of behavior and brain function throughout the course of an individual’s lifespan, though often emphasis is put on childhood and adolescence when the majority of brain development occurs. Research tends to focus on development of important behavioral functions like perception, language, and other cognitive processes. Studies in this field are often centered around children or other individuals with developmental disorders or various kinds of brain related trauma or injury. A key concept of this field is that looks at and attempts to relate the psychological aspects of development, such as behavior, comprehension, cognition, etc., to the specific neural structures; it draws parallels between behavior and mechanism in the brain. Research in this field involves various cognitive tasks and tests as well as neuroimaging. Some of the many conditions studied by developmental neuropsychologists include congenital or acquired brain damage, autism spectrum disorder, attention deficit disorder, executive dysfunction, seizures, intellectual disabilities, obsessive compulsive disorder, stuttering, schizophrenia, developmental aphasia, and other learning delays such as dyslexia, dysgraphia, and dyspraxia.
