Emerging new materialism scholarship provides an exciting theoretical space not only for challenging traditional conceptions of human agency but also for rethinking the role of the material world in shaping political outcomes. Although a wildly diverse intellectual movement, this scholarship shares the common goal of widening traditional understandings of agency to include nonhuman objects. This article adopts insights from cognitive science to extend the concept of political agency beyond the confines of human intention. Instead of focusing on the constraining material characteristics of the nonhuman within a large-scale relational framework, we argue in support of a distributive understanding of agency based on the co-constitutional essence of the mind itself. Specifically, we integrate insights from embodied cognition grounded in dynamical systems theory into the established framework of the hydrosocial cycle to argue that residents’ experiences within an active material world help explain the existence of certain flood risk perceptions. In other words, human intention or agency—as it is commonly understood—comes into existence through a co-constitutional process involving brain, body, and aspects of a wider environment. Using qualitative interview data from two communities along the Yellowstone River in eastern Montana, we support our arguments through an investigation of three types of embodied experiences between residents and the levees that shape risk perception. Key Words: embodied cognition, hydrosocial cycle, new materialism, risk perception.

新兴的唯物主义奖学金不仅为挑战人类代理的传统观念提供了令人兴奋的理论空间，而且为重新思考物质世界在塑造政治结果中的作用提供了令人兴奋的理论空间。尽管这是一场千差万别的知识运动，但这项奖学金的共同目标是扩大对代理的传统理解，以涵盖非人类对象。本文采用认知科学的见解，将政治代理的概念扩展到人类意图之外。我们争论的重点不是支持在大规模关系框架内限制非人类的物质特性，而是基于心理本身的合宪本质，支持对代理的分布式理解。特别，我们将基于动力系统理论的内在认知的见解整合到水社会循环的既定框架中，以论证居民在活跃物质世界中的经历有助于解释某些洪水风险感知的存在。换句话说，人类的意图或代理（通常被理解）是通过涉及大脑，身体和更广阔环境的各个方面的合宪过程而存在的。利用来自蒙大拿州东部黄石河沿岸两个社区的定性访谈数据，我们通过对影响风险感知的居民和堤岸之间的三种类型的体验进行调查，来支持我们的论点。以及更广泛的环境方面。利用来自蒙大拿州东部黄石河沿岸两个社区的定性访谈数据，我们通过对影响风险感知的居民和堤岸之间的三种类型的体验进行调查，来支持我们的论点。以及更广泛的环境方面。利用来自蒙大拿州东部黄石河沿岸两个社区的定性访谈数据，我们通过对影响风险感知的居民和堤岸之间的三种类型的体验进行调查，来支持我们的论点。关键词：体现的认知，社会水循环，新唯物主义，风险感知。
