Psychophysiology is the branch of psychology that is concerned with the physiological bases of psychological processes. While psychophysiology was a general broad field of research in the 1960s and 1970s, it has now become quite specialized, based on methods, topic of studies and scientific traditions. Methods vary as combinations of electrophysiological methods, neuroimaging, and neurochemistry. Topics have branched into subspecializations such as social, sport, cognitive, cardiovascular, clinical and other branches of psychophysiology.
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.
Affective neuroscience is the study of how the brain processes emotions. This field combines neuroscience with the psychological study of personality, emotion, and mood. The basis of emotions and what emotions are remains an issue of debate within the field of affective neuroscience.
Social neuroscience is an interdisciplinary field devoted to understanding the relationship between social experiences and biological systems. Humans are fundamentally a social species, rather than solitary. As such, Homo sapiens create emergent organizations beyond the individual—structures that range from dyads, families, and groups to cities, civilizations, and cultures. In this regard, studies indicate that various social influences, including life events, poverty, unemployment and loneliness can influence health related biomarkers. The term "social neuroscience" can be traced to a publication entitled "Social Neuroscience Bulletin" which was published quarterly between 1988 and 1994. The term was subsequently popularized in an article by John Cacioppo and Gary Berntson, published in the American Psychologist in 1992. Cacioppo and Berntson are considered as the legitimate fathers of social neuroscience. Still a young field, social neuroscience is closely related to personality neuroscience, affective neuroscience and cognitive neuroscience, focusing on how the brain mediates social interactions. The biological underpinnings of social cognition are investigated in social cognitive neuroscience.
Jean Decety is an American–French neuroscientist specializing in developmental neuroscience, affective neuroscience, and social neuroscience. His research focuses on the psychological and neurobiological mechanisms underpinning social cognition, particularly social decision-making, empathy, moral reasoning, altruism, pro-social behavior, and more generally interpersonal relationships. He is Irving B. Harris Distinguished Service Professor at the University of Chicago.
The theory of constructed emotion is a theory in affective science proposed by Lisa Feldman Barrett to explain the experience and perception of emotion. The theory posits that instances of emotion are constructed predictively by the brain in the moment as needed. It draws from social construction, psychological construction, and neuroconstruction.
Vagal tone is activity of the vagus nerve, the 10th cranial nerve and a fundamental component of the parasympathetic branch of the autonomic nervous system. This branch of the nervous system is not under conscious control and is largely responsible for the regulation of several body compartments at rest. Vagal activity results in various effects, including: heart rate reduction, vasodilation/constriction of vessels, glandular activity in the heart, lungs, and digestive tract, liver, immune system regulation as well as control of gastrointestinal sensitivity, motility and inflammation.
Polyvagal theory (PVT) is a collection of proposed evolutionary, neuroscientific, and psychological constructs pertaining to the role of the vagus nerve in emotion regulation, social connection and fear response. The theory was introduced in 1994 by Stephen Porges. There is consensus among experts that the assumptions of the polyvagal theory are untenable. PVT is popular among some clinical practitioners and patients, but it is not endorsed by current social neuroscience.
Michael Inzlicht is professor of psychology at the University of Toronto recognized in the areas of social psychology and neuroscience. Although he has published papers on the topics of prejudice, academic performance, and religion, his most recent interests have been in the topics of self-control, where he borrows methods from affective and cognitive neuroscience to understand the underlying nature of self-control, including how it is driven by motivation.
John Terrence Cacioppo was the Tiffany and Margaret Blake Distinguished Service Professor at the University of Chicago. He founded the University of Chicago Center for Cognitive and Social Neuroscience and was the director of the Arete Initiative of the Office of the Vice President for Research and National Laboratories at the University of Chicago. He co-founded the field of social neuroscience and was member of the department of psychology, department of psychiatry and behavioral neuroscience, and the college until his death in March 2018.
Stephen W. Porges is an American psychologist and neuroscientist. He is the Professor of Psychiatry at the University of North Carolina at Chapel Hill. Porges is also currently Director of the Kinsey Institute Traumatic Stress Research Consortium at Indiana University Bloomington, which studies trauma.
Howard C. Nusbaum is professor at the University of Chicago, United States in the Department of Psychology and its College, and a steering committee member of the Neuroscience Institute. Nusbaum is an internationally recognized expert in cognitive psychology, speech science, and in the new field of social neuroscience. Nusbaum investigates the cognitive and neural mechanisms that mediate spoken language use, as well as language learning and the role of attention in speech perception. In addition, he investigates how we understand the meaning of music, and how cognitive and social-emotional processes interact in decision-making.
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.
Error-related negativity (ERN), sometimes referred to as the Ne, is a component of an event-related potential (ERP). ERPs are electrical activity in the brain as measured through electroencephalography (EEG) and time-locked to an external event or a response. A robust ERN component is observed after errors are committed during various choice tasks, even when the participant is not explicitly aware of making the error; however, in the case of unconscious errors the ERN is reduced. An ERN is also observed when non-human primates commit errors.
The Society for Psychophysiological Research is an international scientific organization with over 800 members worldwide. The society is composed of scientists whose research is focused on the study of the interrelationships between the physiological and psychological aspects of behavior.
Interoception is the collection of senses providing information to the organism about the internal state of the body. This can be both conscious and subconscious. It encompasses the brain's process of integrating signals relayed from the body into specific subregions—like the brainstem, thalamus, insula, somatosensory, and anterior cingulate cortex—allowing for a nuanced representation of the physiological state of the body. This is important for maintaining homeostatic conditions in the body and, potentially, facilitating self-awareness.
The Federation of Associations in Behavioral & Brain Sciences is a Washington, D.C.-based coalition of learned societies dedicated to psychology and related behavioral sciences. Its official journal is Policy Insights from the Behavioral and Brain Sciences, which is published by SAGE Publications.
Neuro-Information-Systems (NeuroIS) is a subfield of the information systems (IS) discipline, which relies on neuroscience and neurophysiological knowledge and tools to better understand the development, use, and impact of information and communication technologies. The field has been formally established at the International Conference on Information Systems (ICIS) in 2007.
