Abstract (English) Current research on cross-species empathy mostly relies on material and phenomenological evidence such as genetic homology, neural circuits, and behavioral observation, presenting a research characteristic of "emphasizing carriers over mechanisms", and has not yet formed a unified, formalizable, and quantifiable underlying explanatory framework. From the perspectives of information science and topology, this paper proposes the Empathetic Topological Theory (Emotional Isomorphism Hypothesis), arguing that the core mechanism of cross-species emotional intercommunication lies in the topological isomorphism of emotional information processing pathways between different living systems, rather than the complete identity of material carriers. This paper constructs a five-layer topological model of emotional information processing with its formal expression, provides an operational definition of topological isomorphism at three scales and designs corresponding quantitative indicators, proposes a cross-species empirical verification scheme based on brain network data, and completes the demarcation from classical theoretical positions at the level of scientific philosophy. Ultimately, it provides a clear, computable, and falsifiable unified theoretical framework for cross-species empathy research, promoting the expansion of this field from the material-centered paradigm to the structure-centered paradigm.

摘要(中文) 当前跨物种共情研究多聚焦基因同源性、神经环路、行为观察等物质与现象层面,呈现“重载体、轻机制”的特征,尚未形成统一、可形式化、可量化的底层解释框架。本文从信息科学与拓扑学视角出发,提出共情拓扑理论(情感同构假说),认为跨物种情感互通的核心机制是不同生命系统间情感信息处理通路的拓扑同构,而非物质载体的完全同一。 文章构建情感信息处理五层拓扑模型并给出形式化表达,对拓扑同构进行三尺度操作化定义与量化指标设计,提出基于脑网络数据的跨物种实证检验方案,在科学哲学层面完成与经典理论立场的划界,最终为跨物种共情研究提供一套结构清晰、可计算、可证伪的统一理论框架,推动该领域从物质中心范式向结构中心范式拓展。 关键词:跨物种共情;信息涌现;拓扑同构;情感信息处理;结构中心主义;情感计算
