Understanding public perceptions of Sustainable Drainage Systems (SuDS) is critical for addressing barriers to their implementation. Perceptions are typically evaluated using explicit measures (e.g. questionnaires) that are subject to biases and may not fully capture attitudes towards SuDS. A novel image-based application of the Implicit Association Test is developed to investigate unconscious perceptions of SuDS in public greenspace and combined with explicit tests to evaluate perceptions of greenspace with and without SuDS, focusing on a sample population in Newcastle-upon-Tyne. Greenspace with or without SuDS is perceived positively by the sample population. Overall, respondents implicitly and explicitly prefer greenspace without SuDS and perceive greenspace without SuDS as more attractive, tidier and safer. The wide distribution of scores for SuDS, nonetheless, suggests a range of opinions and illustrates the complex nature of preferences for the use of greenspace. That the strongly negative explicit scores were not reflected in the implicit tests may suggest that explicit attitudes towards tidiness and safety may not be deep-rooted and are subject to social bias. Combined explicit and implicit tests may help us to understand any disconnect between expressed positive attitudes to natural spaces and behaviours around them and inform SuDS design to increase public acceptance. This article is part of the theme issue 'Urban flood resilience'.
了解公众对可持续排水系统 (SuDS) 的看法对于解决其实施障碍至关重要。通常使用可能存在偏差的明确措施（例如问卷调查）来评估这些看法，但这些措施可能无法完全捕捉到公众对 SuDS 的态度。本研究开发了一种新颖的基于图像的内隐联想测验应用程序，以调查公众对公共绿地中 SuDS 的无意识看法，并将其与明确测试相结合，评估有和没有 SuDS 的绿地的看法，重点关注纽卡斯尔的样本人群。有或没有 SuDS 的绿地受到了样本人群的积极评价。总体而言，受访者在潜意识和意识上都更倾向于没有 SuDS 的绿地，他们认为没有 SuDS 的绿地更具吸引力、更整洁和更安全。然而，SuDS 的评分分布广泛，这表明存在各种意见，并说明了对绿地使用偏好的复杂性质。强烈的负面明确分数并未反映在潜意识测试中，这可能表明对整洁和安全的明确态度可能不是根深蒂固的，并且受到社会偏见的影响。明确和潜意识测试的结合可能有助于我们理解对自然空间的表达积极态度与周围行为之间的脱节，并为提高公众接受度而设计 SuDS。本文是主题为“城市洪水韧性”的特刊的一部分。
