Systems psychology

Systems psychology is a branch of both theoretical psychology and applied psychology that studies human behaviour and experience in 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. Groups and individuals are considered as systems in homeostasis. Alternative terms here are "systemic psychology", "systems behavior", and "systems-based psychology".

In the scientific literature different kind 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.

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.

Family systems 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. Marriage and Family Therapists (MFTs) are the most specifically trained in this type of psychotherapy.
