Abstract

The impact of interior design on human psychology is one of the relevant directions of modern scientific research. Human behavior, emotional state, and overall psychological comfort are shaped by both visual and functional environmental factors. The color of space, lighting, material selection, furniture arrangement, and decorative elements directly influence people’s behavioral responses and emotional states. A psychologically well-designed interior reduces stress levels, increases productivity, and improves overall quality of life. The aim of the study is to examine the psychological effects of interior design on a scientific basis, identify the mechanisms through which modern design elements influence human psychology, and present practical recommendations. Within the scope of the research, various scientific methods were used to evaluate the impact of visual and functional parameters on human behavior, emotional state, and social interactions. Research findings indicate that spatial color palettes, lighting levels, acoustic conditions, positioning, and scale can significantly influence human behavior and emotional responses. For example, warm colors increase energy levels and stimulate activity, while cool colors have a calming effect. Lighting plays a crucial role in ensuring psychological comfort and minimizing eye strain. In addition, furniture layout and spatial organization shape freedom of movement, social interaction, and the sense of personal space. The results of the study demonstrate that a synthesized application of elements such as color, lighting, acoustics, and spatial planning in interior design is more effective in enhancing psychological comfort. This approach allows for the optimization of behavioral patterns and emotional states in both individual and public spaces.
