Emotional State as a Key Driver of Public Preferences for Flower Color
Summary
Researchers investigated what drives public preferences for flower colors in urban landscapes using an online survey with precisely calibrated color samples. They found that emotional state was the strongest predictor of color preference, more influential than demographic or socioeconomic factors. While not directly related to microplastics, the study contributes to understanding how people perceive and value natural environments in urban settings.
Flowers, as integral elements of urban landscapes, are critical not only for aesthetic purposes but also for fostering human–nature interactions in green spaces. However, research on flower color preferences has largely been descriptive, and there is a lack of exploration of potential mechanisms influencing flower color preferences, such as economic and social factors. This study created visual samples through precise color adjustment techniques and introduced the L*, a*, and b* parameters from the CIELAB color system to quantify the flower colors of the survey samples, conducting an online survey with 354 Chinese residents. The complex aesthetic process’s driving factors were unveiled through a comprehensive analysis using a Generalized Additive Model (GAM), a piecewise Structural Equation Model (SEM), and linear regression models. The results show that the public’s flower color preference is primarily related to the a* and b* parameters, which represent color dimensions in the CIELAB color space, and it is not significantly related to L* (lightness). Factors such as age, annual household income level (AI), personal income sources (PI), nature experience, and emotional state (TMD) significantly influence color preferences, with emotional state identified as the most critical factor. Lastly, linear regression models further explain the potential mechanism of the influencing factors. This study proposes a framework to assist urban planners in selecting flower colors that resonate with diverse populations, enhancing both the attractiveness of urban green spaces and their potential to promote pro-environmental behavior. By aligning flower color design with public preferences, this study contributes to sustainable urban planning practices aimed at improving human well-being and fostering deeper connections with nature.

Public perception of microplastics pollution in Switzerland: Psychological distance, concern, and willingness to engage in mitigation activities
Researchers surveyed over 900 people in Switzerland to understand how the public perceives microplastic pollution and their willingness to take action. The study found that people perceive microplastics as a relatively close threat on most psychological dimensions, and that concern about the issue, particularly concern for nature, is a stronger predictor of willingness to engage in mitigation activities than psychological distance alone.
Who worries about microplastics? The relative importance of personal values and individual risk judgements / ¿A quién le preocupan los microplásticos? La importancia relativa de los valores personales y los juicios individuales de riesgo
Researchers surveyed nearly 700 people in Norway to understand what drives public worry about microplastic pollution. They found that personal values and individual risk perceptions were the strongest predictors of concern, more so than demographic factors or general environmental attitudes. The study suggests that communication strategies about microplastic risks should account for how people personally evaluate threats rather than relying solely on scientific information.
Drivers of green purchasing behaviour: a systematic review and a research agenda
This systematic review of 41 studies found that environmental concern, health consciousness, social influence, and perceived value are the strongest drivers of green purchasing behavior. While not directly about microplastics, the findings are relevant to understanding what motivates consumers to choose plastic-free or reduced-plastic products.
Explicitly and Implicitly Measured Valence and Risk Attitudes Towards Plastic Packaging, Plastic Waste, and Microplastic in a German Sample
This psychology study measured both explicit and implicit attitudes toward plastic packaging and microplastics in German consumers, finding that people simultaneously appreciate the convenience of plastic while expressing concern about pollution. The gap between attitudes and behavior helps explain why plastic consumption continues despite public concern about microplastics.
Public knowledge of microplastics for pro-environmental behavior
Researchers analyzed public knowledge of microplastics and its relationship to pro-environmental behavior, finding that because microplastics are invisible to the naked eye, public perception depends entirely on external information sources rather than direct experience, with implications for environmental communication strategies.
