Systems psychology is a branch of both theoretical psychology and applied psychology that studies human behaviour and experience as complex systems. It is inspired by systems theory and systems thinking, and based on the theoretical work of Roger Barker, Gregory Bateson, Humberto Maturana and others. [1] Groups and individuals are considered as systems in homeostasis. Alternative terms here are "systemic psychology", "systems behavior", and "systems-based psychology".[ citation needed ]
In the scientific literature, different kinds of systems psychology have been mentioned:
Ergonomics, also called "human factors", is the application of scientific information concerning objects, systems and environment for human use (definition adopted by the International Ergonomics Association in 2007). Ergonomics is commonly described as the way companies design tasks and work areas to maximize the efficiency and quality of their employees' work. However, ergonomics comes into everything which involves people. Work systems, sports and leisure, health and safety should all embody ergonomics principles if well designed.[ citation needed ]
Equipment design is intended to maximize productivity by reducing operator fatigue and discomfort. The field is also called human engineering and human factors engineering. Ergonomic research is primarily performed by ergonomists who study human capabilities in relationship to their work demands. Information derived from ergonomists contributes to the design and evaluation of tasks, jobs, products, environments and systems in order to make them compatible with the needs, abilities and limitations of people.[ citation needed ]
Family system therapy, also referred to as "family therapy" and "couple and family therapy", is a branch of psychotherapy related to relationship counseling that works with families and couples in intimate relationships to nurture change and development. It tends to view the family as a system, family relationships as an important factor in psychological health. As such, family problems have been seen to arise as an emergent property of systemic interactions, rather than to be blamed on individual members. [11] Marriage and Family Therapists (MFTs) are the most specifically trained in this type of psychotherapy.[ citation needed ]
Industrial and organizational psychology also known as "work psychology", "occupational psychology" or "personnel psychology" concerns the application of psychological theories, research methods, and intervention strategies to workplace issues. Industrial and organizational psychologists are interested in making organizations more productive while ensuring workers are able to lead physically and psychologically healthy lives. Relevant topics include personnel psychology, motivation and leadership, employee selection, training and development, organization development and guided change, organizational behavior, and job and family issues.[ citation needed ]
Perceptual control theory (PCT) is a psychological theory of animal and human behavior originated by William T. Powers. In contrast with other theories of psychology and behavior, which assume that behavior is a function of perception – that perceptual inputs determine or cause behavior – PCT postulates that an organism's behavior is a means of controlling its perceptions. In contrast with engineering control theory, the reference variable for each negative feedback control loop in a control hierarchy is set from within the system (the organism), rather than by an external agent changing the setpoint of the controller. [12] PCT also applies to nonliving autonomic systems. [13]
Evolutionary psychology is a theoretical approach in psychology that examines cognition and behavior from a modern evolutionary perspective. It seeks to identify human psychological adaptations with regards to the ancestral problems they evolved to solve. In this framework, psychological traits and mechanisms are either functional products of natural and sexual selection or non-adaptive by-products of other adaptive traits.
Psychology is the scientific study of mind and behavior. Its subject matter includes the behavior of humans and nonhumans, both conscious and unconscious phenomena, and mental processes such as thoughts, feelings, and motives. Psychology is an academic discipline of immense scope, crossing the boundaries between the natural and social sciences. Biological 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.
Personality psychology is a branch of psychology that examines personality and its variation among individuals. It aims to show how people are individually different due to psychological forces. Its areas of focus include:
Systems theory is the transdisciplinary study of systems, i.e. cohesive groups of interrelated, interdependent components that can be natural or artificial. Every system has causal boundaries, is influenced by its context, defined by its structure, function and role, and expressed through its relations with other systems. A system is "more than the sum of its parts" when it expresses synergy or emergent behavior.
Albert Bandura was a Canadian-American psychologist. He was a professor of social science in psychology at Stanford University.
Abnormal psychology is the branch of psychology that studies unusual patterns of behavior, emotion, and thought, which could possibly be understood as a mental disorder. Although many behaviors could be considered as abnormal, this branch of psychology typically deals with behavior in a clinical context. There is a long history of attempts to understand and control behavior deemed to be aberrant or deviant, and there is often cultural variation in the approach taken. The field of abnormal psychology identifies multiple causes for different conditions, employing diverse theories from the general field of psychology and elsewhere, and much still hinges on what exactly is meant by "abnormal". There has traditionally been a divide between psychological and biological explanations, reflecting a philosophical dualism in regard to the mind–body problem. There have also been different approaches in trying to classify mental disorders. Abnormal includes three different categories; they are subnormal, supernormal and paranormal.
Applied psychology is the use of psychological methods and findings of scientific psychology to solve practical problems of human and animal behavior and experience. Educational and organizational psychology, business management, law, health, product design, ergonomics, behavioural psychology, psychology of motivation, psychoanalysis, neuropsychology, psychiatry and mental health are just a few of the areas that have been influenced by the application of psychological principles and scientific findings. Some of the areas of applied psychology include counseling psychology, industrial and organizational psychology, engineering psychology, occupational health psychology, legal psychology, school psychology, sports psychology, community psychology, neuropsychology, medical psychology and clinical psychology, evolutionary psychology, human factors, forensic psychology and traffic psychology. In addition, a number of specialized areas in the general area of psychology have applied branches. However, the lines between sub-branch specializations and major applied psychology categories are often mixed or in some cases blurred. For example, a human factors psychologist might use a cognitive psychology theory. This could be described as human factor psychology or as applied cognitive psychology. When applied psychology is used in the treatment of behavioral disorders there are many experimental approaches to try and treat an individual. This type of psychology can be found in many of the subbranches in other fields of psychology.
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.
Activity theory is an umbrella term for a line of eclectic social-sciences theories and research with its roots in the Soviet psychological activity theory pioneered by Sergei Rubinstein in the 1930s. It was later advocated for and popularized by Alexei Leont'ev. Some of the traces of the theory in its inception can also be found in a few works of Lev Vygotsky. These scholars sought to understand human activities as systemic and socially situated phenomena and to go beyond paradigms of reflexology and classical conditioning, psychoanalysis and behaviorism. It became one of the major psychological approaches in the former USSR, being widely used in both theoretical and applied psychology, and in education, professional training, ergonomics, social psychology and work psychology.
Theoretical psychology is concerned with theoretical and philosophical aspects of psychology. It is an interdisciplinary field with a wide scope of study.
Person-centered therapy (PCT), also known as person-centered psychotherapy, person-centered counseling, client-centered therapy and Rogerian psychotherapy, is a form of psychotherapy developed by psychologist Carl Rogers and colleagues beginning in the 1940s and extending into the 1980s. Person-centered therapy seeks to facilitate a client's actualizing tendency, "an inbuilt proclivity toward growth and fulfillment", via acceptance, therapist congruence (genuineness), and empathic understanding.
Perceptual control theory (PCT) is a model of behavior based on the properties of negative feedback control loops. A control loop maintains a sensed variable at or near a reference value by means of the effects of its outputs upon that variable, as mediated by physical properties of the environment. In engineering control theory, reference values are set by a user outside the system. An example is a thermostat. In a living organism, reference values for controlled perceptual variables are endogenously maintained. Biological homeostasis and reflexes are simple, low-level examples. The discovery of mathematical principles of control introduced a way to model a negative feedback loop closed through the environment, which spawned perceptual control theory. It differs fundamentally from some models in behavioral and cognitive psychology that model stimuli as causes of behavior. PCT research is published in experimental psychology, neuroscience, ethology, anthropology, linguistics, sociology, robotics, developmental psychology, organizational psychology and management, and a number of other fields. PCT has been applied to design and administration of educational systems, and has led to a psychotherapy called the method of levels.
Cognitive ergonomics is a scientific discipline that studies, evaluates, and designs tasks, jobs, products, environments and systems and how they interact with humans and their cognitive abilities. It is defined by the International Ergonomics Association as "concerned with mental processes, such as perception, memory, reasoning, and motor response, as they affect interactions among humans and other elements of a system. Cognitive ergonomics is responsible for how work is done in the mind, meaning, the quality of work is dependent on the persons understanding of situations. Situations could include the goals, means, and constraints of work. The relevant topics include mental workload, decision-making, skilled performance, human-computer interaction, human reliability, work stress and training as these may relate to human-system design." Cognitive ergonomics studies cognition in work and operational settings, in order to optimize human well-being and system performance. It is a subset of the larger field of human factors and ergonomics.
Gary Klein is a research psychologist famous for pioneering in the field of naturalistic decision making. By studying experts such as firefighters in their natural environment, he discovered that laboratory models could not adequately describe decision making under time pressure and uncertainty. His recognition-primed decision (RPD) model has influenced changes in the ways the Marines and Army train their officers to make decisions. The concept of expertise has been central to the models he has developed, the research he has conducted, and the training and design efforts he has accomplished.
A system is a group of interacting or interrelated elements that act according to a set of rules to form a unified whole. A system, surrounded and influenced by its environment, is described by its boundaries, structure and purpose and is expressed in its functioning. Systems are the subjects of study of systems theory and other systems sciences.
Organismic theories in psychology are a family of holistic psychological theories which tend to stress the organization, unity, and integration of human beings expressed through each individual's inherent growth or developmental tendency. The idea of an explicitly "organismic theory" dates at least back to the publication of Kurt Goldstein's The organism: A holistic approach to biology derived from pathological data in man in 1934. Organismic theories and the "organic" metaphor were inspired by organicist approaches in biology. The most direct influence from inside psychology comes from Gestalt psychology. This approach is often contrasted with mechanistic and reductionist perspectives in psychology.
Functional psychology or functionalism refers to a psychological school of thought that was a direct outgrowth of Darwinian thinking which focuses attention on the utility and purpose of behavior that has been modified over years of human existence. Edward L. Thorndike, best known for his experiments with trial-and-error learning, came to be known as the leader of the loosely defined movement. This movement arose in the U.S. in the late 19th century in direct contrast to Edward Titchener's structuralism, which focused on the contents of consciousness rather than the motives and ideals of human behavior. Functionalism denies the principle of introspection, which tends to investigate the inner workings of human thinking rather than understanding the biological processes of the human consciousness.
Anthony D. Andre is a researcher, practitioner, and academic in the fields of human factors, ergonomics, usability and product design. He is the founding principal of Interface Analysis Associates, an international human factors and ergonomics consultancy. Andre pioneered the behavioral approach to ergonomics which included behavior modification and computer skill development as its basis, in direct opposition to common product-based approaches. He is a founding member and adjunct professor of the HF/E Graduate Program at San Jose State University. He founded the International Conference on Human Factors and Ergonomics in Health Care, co-created the Ergo-X conference, managed the ergonomic content for several of the annual California Association of Rehabilitation and Re-employment Professionals (CARRP) conferences, and recently produced, hosted, and presented a COVID-19 ergonomics virtual summit on how to work/school from home more safely and comfortably. He has served as president of the Human Factors and Ergonomics Society. Andre is a Certified Professional Ergonomist (CPE), recognized by the Board of Certification of Professional Ergonomists (BCPE).
Ergonomics, also known as human factors or human factors engineering (HFE), is the application of psychological and physiological principles to the engineering and design of products, processes, and systems. Primary goals of human factors engineering are to reduce human error, increase productivity and system availability, and enhance safety, health and comfort with a specific focus on the interaction between the human and equipment.
