A recent study indicates that the human brain applies different aesthetic standards when evaluating paintings and architectural structures, suggesting that these preferences are domain-specific rather than universal.
A recent study published in the journal Psychology of Aesthetics, Creativity, and the Arts sheds light on the intricate ways in which the human brain perceives beauty in different forms of visual art, revealing that aesthetic judgments for paintings and architectural designs are governed by distinct standards. The research, led by Norberto Grzywacz, a professor of psychology at Loyola University Chicago, indicates that architects and painters evaluate key aesthetic features such as symmetry, balance, and complexity in fundamentally different ways.
Grzywacz’s inquiry into the brain’s Valuation System—responsible for assigning value in decision-making processes—has led him to explore whether aesthetic values are universal across different sensory domains, such as vision and audition, or if they vary depending on the type of visual art. “At some point, I asked myself whether aesthetic values in a sensory domain, for example vision, are universal or specific to different domains,” Grzywacz explained.
Understanding Aesthetic Values
The Valuation System utilizes various neural circuits to establish our preferences, functioning across multiple sensory modalities, including visual perception, taste, and smell. Grzywacz’s research highlights the surprising finding that even within the visual domain, the brain stores aesthetic values differently based on the category of art.
Current computational models that attempt to describe how individuals learn aesthetic values generally assume a universal application of visual criteria across different artistic forms. However, this assumption is challenged by observable differences in how people respond to paintings versus buildings. For example, a poorly balanced structure may evoke discomfort, leading architects to enhance balance in their designs to promote a sense of stability, while artists may intentionally create imbalance to convey movement or emotional intensity in their work.
Research Methodology
To investigate these hypotheses, the researchers conducted a comparative analysis of visual properties between architecture and paintings from a specific era characterized by artistic and architectural freedom. The study focused on Haussmann’s Renovation of Paris, which occurred between 1853 and 1870. During this period, architects were afforded significant financial resources to redesign the city, coinciding with a flourishing art scene populated by many prominent artists.
The study involved collecting photographs of 55 residential building facades constructed during this renovation, ensuring that the images were taken under similar lighting conditions and angles. For the artistic counterpart, 142 paintings completed between 1853 and 1870 were selected from the Louvre and Orsay museum collections, ensuring both historical and geographical consistency.
Utilizing a computer program, the researchers analyzed various visual properties of both sets of images, measuring aspects such as light intensity, spatial arrangement, and color variation. They specifically assessed three types of visual complexity and calculated the balance and symmetry of each image, using statistical tests to compare the two domains’ data.
Findings and Conclusions
The analysis revealed significant differences in how aesthetic variables were applied to architecture versus paintings. Interestingly, the study found that buildings exhibited higher levels of visual complexity than paintings, with architectural styles displaying greater variations in light and spatial boundaries. In contrast, many paintings featured uniform skin tones and blended backgrounds, resulting in lower complexity scores.
Architectural images were characterized by a pronounced sense of balance and symmetry, often evenly distributing visual weight across their center. Conversely, paintings frequently displayed more imbalance, as artists tended to cluster important elements on one side of the canvas. The study also noted that buildings exhibited high spatial periodicity, showing a tendency for repeating patterns, which were less prevalent in paintings, where a variety of orientations were more common.
Moreover, the research indicated that the medium or artistic movement did not substantially influence the aesthetic values measured, with the exception of Impressionist works, which presented a noticeable increase in color complexity. Both categories, however, demonstrated a preference for warm, orange tones, suggesting a universal human affinity for calming earth colors.
Limitations and Future Research
While the findings contribute to understanding aesthetic values, the study’s reliance on analyzing final artistic products instead of directly assessing human observers presents a limitation. Grzywacz cautioned that these results do not definitively establish whether the brain possesses separate aesthetic values for art and architecture, as future research could benefit from involving participant feedback.
Another limitation arises from focusing on a specific historical period and geographic location, with the potential for different statistical patterns emerging from other eras, such as the Renaissance or Baroque periods. Grzywacz emphasized the need to explore varying factors influencing aesthetic values, including personal differences, mental health considerations, and the impact of artificial intelligence on societal values.
In conclusion, the study titled “Domain-Specific Aesthetic Values: A Comparison of Paintings and Architecture,” authored by Norberto M. Grzywacz, Consuelo M. Correa, and Ivan Correa-Herran, opens new avenues for understanding how we perceive beauty across different artistic domains and highlights the complexities of human aesthetic appreciation.
