Concepts, episodes, percepts, and task contexts are represented as typed, weighted graphs whose nodes may carry internal subgraph payloads; edges are typed under six relation classes—causal, containment, temporal, associative, evidential, and spatial. Durable belief graphs are separated from capacity-limited working-memory graphs that may host transient non-belief content. WM–belief grounding, conflict catalogs, and belief-update operators specify how transient structure is tested against stored knowledge and how belief is revised. A reusable operator toolkit—activation, graph-property functionals, working-memory transitions, awareness and trajectory functionals, and belief update—organizes the formal core. Derived diagnostics such as fragmentation, involvement, signed evaluation, coherence, and active conflict define familiar phenomena in the same ontology; self-related processing is modeled through designated self-image subgraphs within belief. Subsequent sections instantiate this core without new primitives: phenomena signatures, a task-instantiation schema for action selection and failure modes, and compatibility mappings that embed ACT-R, Soar, Sigma, the Common Model of Cognition, Global Workspace Theory, semantic networks, Theory-Theory, and chunking as constrained regions of one language. Mappings constitute the culminating technical section; discussion addresses scope, limitations, and open research directions. The contribution is intentionally foundational: a transparent representational substrate for later empirical, computational, and domain-specific work.  \n1 Introduction  \nTheoretical cognitive science has long been marked by fragmentation. The field has produced many successful local theories of memory, reasoning, perception, language, control, and learning, but it still lacks a common representational language in which these theories can be stated, compared, and revised on equal footing [29, 24] . This makes integration difficult: two theories may appear incompatible simply because they are expressed in different formal systems, even when they are making structurally similar claims. The central problem, then, is not only how cognition works, but how cognitive science should represent what its theories are about.  \nMany integrative architectures unify cognition by committing to a particular processing mechanism, such as a production system, a workspace, or a control loop. That approach is valuable, but it often forces translation into one architecture’s native procedural vocabulary before theories can be compared. What is missing is a representational layer prior to mechanism: a shared substrate in which theories can be expressed as structural commitments, so that comparison turns on what cognitive structure they assume rather than on how they happen to be implemented.  \nNEST (Nested Episodic State Topology) is motivated by this gap. It proposes a graph-theoretic representational ontology in which cognition is modeled as structured state formation and transformation. Cognitive states are nested graphs whose nodes can carry internal structure, including  \nsubgraphs, so that concepts, episodes, percepts, and task contexts can be represented in one formal language while preserving typed relations among causal, temporal, spatial, associative, evidential, and containment structure.  \nHuman cognition must also distinguish transient content from durable knowledge—tentative hypotheses, unresolved conflict, and stored beliefs that guide interpretation and action. A single undifferentiated memory store does not capture these distinctions well enough ","cbCaijA64RzNsd8O","https://ap.wps.com/l/cbCaijA64RzNsd8O","pdf",557683,2,1,41,"English","en",105,"#
