Psychology is the study of mind and behavior in humans and non-humans. Psychology includes the study of conscious and unconscious phenomena, including feelings and thoughts. It is an academic discipline of immense scope, crossing the boundaries between the natural and social sciences. Psychologists seek an understanding of the emergent properties of brains, linking the discipline to neuroscience. As social scientists, psychologists aim to understand the behavior of individuals and groups.
Cognitive neuroscience is the scientific field that is concerned with the study of the biological processes and aspects that underlie cognition, with a specific focus on the neural connections in the brain which are involved in mental processes. It addresses the questions of how cognitive activities are affected or controlled by neural circuits in the brain. Cognitive neuroscience is a branch of both neuroscience and psychology, overlapping with disciplines such as behavioral neuroscience, cognitive psychology, physiological psychology and affective neuroscience. Cognitive neuroscience relies upon theories in cognitive science coupled with evidence from neurobiology, and computational modeling.
A mental disorder is an impairment of the mind disrupting normal thinking, feeling, mood, behavior, or social interactions, and accompanied by significant distress or dysfunction. The causes of mental disorders are very complex and vary depending on the particular disorder and the individual. Although the causes of most mental disorders are not fully understood, researchers have identified a variety of biological, psychological, and environmental factors that can contribute to the development or progression of mental disorders. Most mental disorders result in a combination of several different factors rather than just a single factor.
In the field of psychology, cognitive dissonance is the perception of contradictory information and the mental toll of it. Relevant items of information include a person's actions, feelings, ideas, beliefs, values, and things in the environment. Cognitive dissonance is typically experienced as psychological stress when persons participate in an action that goes against one or more of those things. According to this theory, when two actions or ideas are not psychologically consistent with each other, people do all in their power to change them until they become consistent. The discomfort is triggered by the person's belief clashing with new information perceived, wherein the individual tries to find a way to resolve the contradiction to reduce their discomfort.
Philosophy of psychology is concerned with the history and foundations of psychology. It deals with both epistemological and ontological issues and shares interests with other fields, including philosophy of mind and theoretical psychology. Philosophical and theoretical psychology are intimately tied and are therefore sometimes used interchangeably or used together. However, philosophy of psychology relies more on debates general to philosophy and on philosophical methods, whereas theoretical psychology draws on multiple areas.
Neuropsychology is a branch of psychology 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.
Social cognition is a topic within psychology that focuses on how people process, store, and apply information about other people and social situations. It focuses on the role that cognitive processes play in social interactions.
Clinical psychology is an integration of human science, behavioral science, theory, and clinical knowledge for the purpose of understanding, preventing, and relieving psychologically-based distress or dysfunction and to promote subjective well-being and personal development. Central to its practice are psychological assessment, clinical formulation, and psychotherapy, although clinical psychologists also engage in research, teaching, consultation, forensic testimony, and program development and administration. In many countries, clinical psychology is a regulated mental health profession.
Behaviorism is a systematic approach to understanding the behavior of humans and other animals. It assumes that behavior is either a reflex evoked by the pairing of certain antecedent stimuli in the environment, or a consequence of that individual's history, including especially reinforcement and punishment contingencies, together with the individual's current motivational state and controlling stimuli. Although behaviorists generally accept the important role of heredity in determining behavior, they focus primarily on environmental events.
Psychology is defined as "the scientific study of behavior and mental processes". Philosophical interest in the human mind and behavior dates back to the ancient civilizations of Egypt, Persia, Greece, China, and India.
Michael I. Posner is an American psychologist who is a researcher in the field of attention, and the editor of numerous cognitive and neuroscience compilations. He is emeritus professor of psychology at the University of Oregon, and an adjunct professor at the Weill Medical College in New York. A Review of General Psychology survey, published in 2002, ranked Posner as the 56th most cited psychologist of the 20th century.
Energy is a concept in some psychological theories or models of a postulated unconscious mental functioning on a level between biology and consciousness.
Neuropsychoanalysis integrates both neuroscience and psychoanalysis, to create a balanced and equal study of the human mind. This overarching approach began as advances in neuroscience lead to breakthroughs which held pertinent information for the field of psychoanalysis. Despite advantages for these fields to interconnect, there is some concern that too much emphasis on neurobiological physiology of the brain will undermine the importance of dialogue and exploration that is foundational to the field of psychoanalysis. Critics will also point to the qualitative and subjective nature of the field of psychoanalysis, claiming it cannot be fully reconciled with the quantitative and objective nature of neuroscientific research. However, despite this critique, proponents of the field of neuropsychoanalysis remind critics that the father of psychoanalysis, Sigmund Freud himself, began his career as a neuroanatomist, further arguing that research in this category proves that the psychodynamic effects of the mind are inextricably linked to neural activity in the brain. Indeed, neuroscientific progress has created a shared study of many of the same cognitive phenomenon, and proponents for a distinct field under the heading of neuropsychoanalysis point to the ability for observation of both the subjective mind and empirical evidence in neurobiology to provide greater understanding and greater curative methods. Therefore, neurospsychoanalysis aims to bring a field, often viewed as belonging more to the humanities than the sciences, into the scientific realm and under the umbrella of neuroscience, distinct from psychoanalysis, and yet adding to the plethora of insight garnered from it.
Nora S. Newcombe is the Laura H. Carnell Professor of Psychology and the James H. Glackin Distinguished Faculty Fellow at Temple University. She is a Canadian-American researcher in cognitive development, cognitive psychology and cognitive science, and expert on the development of spatial thinking and reasoning and episodic memory. She was the principal investigator of the Spatial Intelligence and Learning Center (2006-2018), one of six Science of Learning Centers funded by the National Science Foundation.
Some of the research that is conducted in the field of psychology is more "fundamental" than the research conducted in the applied psychological disciplines, and does not necessarily have a direct application. The subdisciplines within psychology that can be thought to reflect a basic-science orientation include biological psychology, cognitive psychology, neuropsychology, and so on. Research in these subdisciplines is characterized by methodological rigor. The concern of psychology as a basic science is in understanding the laws and processes that underlie behavior, cognition, and emotion. Psychology as a basic science provides a foundation for applied psychology. Applied psychology, by contrast, involves the application of psychological principles and theories yielded up by the basic psychological sciences; these applications are aimed at overcoming problems or promoting well-being in areas such as mental and physical health and education.
Cultural neuroscience is a field of research that focuses on the interrelation between a human's cultural environment and neurobiological systems. The field particularly incorporates ideas and perspectives from related domains like anthropology, psychology, and cognitive neuroscience to study sociocultural influences on human behaviors. Such impacts on behavior are often measured using various neuroimaging methods, through which cross-cultural variability in neural activity can be examined.
Psychology encompasses a vast domain, and includes many different approaches to the study of mental processes and behavior. Below are the major areas of inquiry that taken together constitute psychology. A comprehensive list of the sub-fields and areas within psychology can be found at the list of psychology topics and list of psychology disciplines.
Russell "Russ" Alan Poldrack is an American psychologist and neuroscientist. He is a professor of psychology at Stanford University, associate director of Stanford Data Science, member of the Stanford Neuroscience Institute and director of the Stanford Center for Reproducible Neuroscience and the SDS Center for Open and Reproducible Science.
Social cognitive neuroscience is the scientific study of the biological processes underpinning social cognition. Specifically, it uses the tools of neuroscience to study "the mental mechanisms that create, frame, regulate, and respond to our experience of the social world". Social cognitive neuroscience uses the epistemological foundations of cognitive neuroscience, and is closely related to social neuroscience. Social cognitive neuroscience employs human neuroimaging, typically using functional magnetic resonance imaging (fMRI). Human brain stimulation techniques such as transcranial magnetic stimulation and transcranial direct-current stimulation are also used. In nonhuman animals, direct electrophysiological recordings and electrical stimulation of single cells and neuronal populations are utilized for investigating lower-level social cognitive processes.
