Psychology in Architectural Design | SXSW 2021

The Psychological Impact of Physical Space
📌 The difference between a house and a home is psychological, rooted in feelings of protection, provision, and love.
🏠 Humans have an inherent desire to create and inhabit spaces, moving from the basic need for shelter to creating spaces for delight and joy.
🏢 Buildings serve as the physical foundation of contexts upon which individual success and interactions with society are built.
🧠 The physical environment impacts almost every aspect of psychology, including happiness, productivity, and creativity, often on an unconscious level.

Design, Psychology, and Connection to Space
🔬 Research aims to bridge the gap between design/architecture and psychology to better understand human-environment interactions.
🔄 People connect to spaces in three main ways: identity claims (statements of self), thought and feeling regulators (personal mementos for emotional control), and behavioral residue (traces of past actions, like messiness).
🌳 A famous study by Roger Ulrich showed that patients with views of trees required less pain medication and had shorter hospital stays than those facing a brick wall, demonstrating the power of natural views.
💡 Personalization is key in one's "near environment" (immediate surroundings) to allow individuals to express themselves functionally and aesthetically.

Collaboration and Evidence-Based Design
❓ Intentions are crucial in design; decisions like paint color or furniture choice are arbitrary without knowing the desired psychological outcome for a space (e.g., home vs. classroom).
📊 Research involves defining a lexicon of terms to systematically describe space dimensions and the desired emotional states (ambiances) within them.
📝 For individual workspaces, desired ambiances included comfortable, productive, focused, and organized, whereas social spaces favored entertaining, fun, friendly, and communal.
🚫 Designers relying solely on intuition often disagree; collaborating with psychologists allows for an evidence-based approach, moving beyond subjective opinions.

Key Points & Insights
➡️ Architects should develop a scientific language to match design decisions with specific psychological outcomes, much like calculating structural requirements.
➡️ Psychologists must package their findings into usable guides so designers can look up procedures to evoke specific ambiences (e.g., "create a sense of wonder").
➡️ A critical area for low-hanging fruit improvement is sleep quality; understanding psychological factors to improve sleep by even 10% offers massive societal benefits.
➡️ Designers should take responsibility to engage in evidence-based practice, setting ego aside to focus on research for the betterment of the collective good.
