The Evolution of Environmental Psychology: A Historical Overview

Every building you walk into, every park bench you sit on, and every crowded subway car you endure shapes how you feel, think, and behave. This idea-that our physical surroundings have a measurable impact on our psychology-seems obvious today. But for most of psychology’s history, the physical environment was treated as background noise. It took a unique convergence of urban crises, architectural failures, and cross-disciplinary thinking in the mid-20th century to give rise to environmental psychology, a field dedicated to understanding the two-way relationship between people and their surroundings. Let’s trace how this discipline grew from scattered observations into a recognized area of study.

Early roots: before there was a name 🔗

Long before “environmental psychology” became an established term, researchers in different parts of the world were already exploring connections between people and their surroundings. In the early 1900s, German scholars such as Willy Hellpach examined how weather, climate, and landscape influenced the human psyche. His work, published as Geopsyche in 1911, is considered one of the earliest attempts to systematically link environmental conditions to psychological experience. Around the same time, Gestalt psychologists were developing ideas about how people perceive their environments as organized wholes rather than isolated stimuli. These early European contributions laid important conceptual groundwork, even though a distinct discipline had not yet formed.

In the United States, the Chicago School of Sociology in the 1920s and 1930s became another crucial influence. Sociologists like Robert Park and Ernest Burgess studied urban life, examining how the structure of city neighbourhoods shaped social behavior, crime patterns, and community identity. Their ecological approach to understanding cities-treating urban areas as living organisms with distinct zones-foreshadowed many ideas that environmental psychologists would later adopt.

The post-war building boom and the need for research 🔗

World War II proved to be a major turning point. The massive destruction caused by the war created an urgent need for reconstruction across Europe and North America. Governments needed evidence-based guidance on how to design housing, hospitals, schools, and workplaces that actually served the people who used them.

In the United Kingdom, institutions like the Building Research Centre began studying how people used living spaces, investigating everything from noise levels and heating to lighting requirements. At the same time, the Pilkington Research Unit-led by Thomas Markus-focused on the influence of natural daylight in buildings and developed practical guidelines for architects. These applied research efforts were among the first to bring psychological questions directly into architectural practice.

In the United States, a parallel development was underway. Psychiatrists and architects began collaborating to improve the design of psychiatric hospitals. The existing hospital environments were often found to worsen patients’ conditions rather than aid recovery. This realization-that the built environment could actively harm mental health-pushed professionals to rethink the relationship between design and well-being.

Roger Barker and the birth of ecological psychology 🔗

One of the most important precursors to environmental psychology was the work of Roger Barker. In 1947, Barker and his colleague Herbert Wright established the Midwest Psychological Field Station in Oskaloosa, Kansas-a small town of fewer than 2,000 people. Their goal was to study human behavior in natural, everyday settings rather than in the artificial conditions of a laboratory.

Over 25 years of meticulous observation, Barker developed the concept of behavior settings-the idea that specific physical and social environments carry their own programs of expected behavior. A church service, a basketball game, and a classroom each demand different actions from the people within them. Barker’s research demonstrated that the best predictor of a person’s behavior was not their personality traits but the setting they were in. This finding was radical for its time and provided a strong empirical foundation for the idea that environments shape behavior in powerful, predictable ways.

Barker’s work was published in his landmark book Ecological Psychology (1968), and it influenced generations of researchers interested in person-environment interactions.

The 1960s: environmental psychology becomes a discipline 🔗

The 1960s are widely regarded as the decade when environmental psychology formally emerged as its own field. Several forces converged to make this possible: rapid urbanization, growing environmental concerns about pollution, and an increasing awareness that poorly designed buildings and cities were taking a psychological toll on their inhabitants.

The CUNY program and the founding figures 🔗

A defining moment came in 1968, when the City University of New York (CUNY) Graduate Center launched what is widely considered the first doctoral program in environmental psychology. The program was spearheaded by Harold Proshansky, William Ittelson, and Leanne Rivlin-social and developmental psychologists who had been studying how the design of psychiatric hospitals affected patient behavior and mental health outcomes.

Their collaborative work at CUNY produced the first major textbook in the field, Environmental Psychology: Man and His Physical Setting (1970), which was instrumental in defining the boundaries and scope of the discipline. Proshansky, in particular, championed a problem-oriented and value-oriented approach. He argued that environmental psychology should study real-world problems as they occurred in actual settings, not in controlled laboratory conditions. He also emphasized that the field had a responsibility to improve people’s lives, not just to produce abstract knowledge.

Key concepts that shaped the early field 🔗

During this same period, several other scholars made contributions that became foundational to environmental psychology:

Robert Sommer published Personal Space (1969), a groundbreaking exploration of how people use and defend the invisible boundaries around their bodies in social interactions. Edward T. Hall, an anthropologist, coined the term proxemics to describe how people from different cultures relate to one another spatially. And architect Amos Rapoport demonstrated in House Form and Culture (1969) that the design of buildings was not purely functional but deeply influenced by cultural values and social norms. These diverse contributions highlighted the inherently interdisciplinary nature of environmental psychology from its very beginning.

The 1970s and 1980s: growth and expansion 🔗

The 1970s saw environmental psychology gain broader academic legitimacy. University courses and research programs began appearing across the United States and Europe. In the UK, David Canter at the University of Strathclyde expanded traditional ergonomics into a broader study of how people are “situated” within their environments. He went on to found the Journal of Environmental Psychology in 1981, which became one of the field’s most important publication outlets. The University of Surrey launched one of the first dedicated architecture-psychology courses in the UK in 1973.

This era also saw the founding of key professional organizations like the Environmental Design Research Association (EDRA), which brought together architects, urban planners, social scientists, and psychologists to share findings and develop shared frameworks.

The rise of environmental stress research 🔗

During the 1980s, researchers increasingly turned their attention to environmental stress-the psychological and physiological harm caused by factors like noise pollution, crowding, poor air quality, and lack of access to natural environments. This line of research had significant practical implications, influencing building codes, urban planning policies, and workplace design standards.

A particularly influential figure was Robert Ulrich, whose 1984 study found that hospital patients with a view of trees recovered faster than those facing a brick wall. This study became one of the most cited in environmental psychology and helped establish a strong evidence base for the psychological benefits of contact with nature.

The shift toward sustainability 🔗

By the late 1980s and into the 1990s, environmental psychology began undergoing a significant transformation. The field had originally been focused primarily on the built environment-how the design of buildings, rooms, and cities affected behavior and well-being. But growing awareness of global ecological crises, from ozone depletion to climate change, prompted a major shift in focus.

As researchers from multiple disciplines noted, environmental psychology increasingly took on questions about pro-environmental behavior: Why do some people recycle while others don’t? What motivates energy conservation? How can communities be encouraged to adopt sustainable practices? This “green” turn transformed the discipline from one concerned primarily with how environments affect people into one equally concerned with how people affect environments.

Enric Pol, a professor of social psychology at the University of Barcelona, described this evolution in his influential series Blueprints for a History of Environmental Psychology (2006, 2007). He argued that the field had moved through four broad stages: from its early German origins, through an American transition period, into the era of architectural psychology, and finally into the current focus on environmental psychology for sustainability.

Two strands of modern environmental psychology 🔗

This shift was not entirely smooth. As the field expanded, it split into two somewhat distinct strands. The first, often called “social” environmental psychology, continued the tradition of studying how physical spaces affect human experience, drawing heavily on social psychology and emphasizing experiential and symbolic aspects of person-place relationships. The second strand, “green” environmental psychology, adopted approaches from cognitive psychology and environmental science, with a focus on ecological challenges, environmental attitudes, and resource management behaviors.

The challenge of integrating these two strands-understanding both the impact of environments on people and the impact of people on environments-remains one of the central tasks of the field today.

The interdisciplinary character of environmental psychology 🔗

One of the most distinctive features of environmental psychology, evident throughout its history, is its deeply interdisciplinary nature. Unlike many subfields of psychology that developed primarily within psychology departments, environmental psychology drew contributors from architecture, urban planning, geography, sociology, anthropology, and the design professions from the very start.

The early scholars of the field included psychologists like Barker, Proshansky, and Ittelson, but also anthropologists like Edward T. Hall, architects like Amos Rapoport, and urban planners influenced by thinkers such as Jane Jacobs-whose advocacy for walkable, human-scale cities resonated deeply with environmental psychology’s core concerns. This cross-pollination gave the field a practical orientation that set it apart: environmental psychologists were not just interested in understanding behavior in theory but in designing better spaces, policies, and interventions.

As the field matured, it also adopted a wide range of research methods. While early researchers like Barker favoured naturalistic field observation, later scholars incorporated experimental studies, surveys, geographic information systems (GIS), ethnographic research, and even virtual reality simulations. This methodological pluralism remains one of the field’s strengths.

Environmental psychology today 🔗

Today, environmental psychology is a well-established area of research and practice with particular urgency given current global challenges. Climate change, urbanization, environmental injustice, and the growing role of digital environments have all expanded the field’s scope. Researchers are now studying topics like climate anxiety, the psychological effects of digital and virtual spaces, the impact of green building design on occupant well-being, and how to encourage communities to adopt sustainable behaviors at scale.

Despite its growth, environmental psychology still faces challenges. Harold Proshansky himself expressed concern that the field had not grown enough to match the size and influence of mainstream psychology subfields like social, cognitive, or personality psychology. The number of dedicated graduate programs remains limited-the CUNY program is still one of the only doctoral programs in the United States specifically devoted to environmental psychology.

Yet the questions environmental psychology asks have never been more relevant. As cities grow denser, as climate impacts intensify, and as our understanding of the built environment’s influence on health deepens, this field is uniquely positioned to offer evidence-based insights that can improve the design of our homes, workplaces, cities, and public spaces.

What do you think? How much do your daily surroundings-your office, your neighbourhood, the parks you visit-affect how you feel and behave? And as cities continue to grow and change, whose responsibility should it be to ensure that built environments support psychological well-being?
