Emergent cognitive convergence is the spontaneous development of shared computational mechanisms, internal representations, and functional architectures across biological brains and artificial intelligence, enabling unified performance, abstraction, and flexibility across diverse cognitive domains. This phenomenon unfolds at multiple scales: within neural circuits and AI layers, among agents in structured systems, and in collectives that integrate human and machine cognition. The following sections delineate its formal basis, phylogenetic trajectories, mathematical frameworks, mechanistic substrates, and empirical manifestations.

1. World-Model-Based Computation and Predictive Error Learning

The convergence of brain and AI cognition is anchored in world-model-based computation, wherein systems continually build and refine internal simulators of the environment from streaming inputs. In the neocortex, hierarchical predictive coding circuits attempt to forecast incoming sensory activity; mismatches (prediction errors) propagate upward, driving synaptic weight changes via unsupervised Hebbian-like learning: $\Delta w = \eta \cdot \delta \cdot x_\text{pre}$ , where $\delta = x_\text{actual} - x_\text{predicted}$ . Cerebellar networks, via feedback loops between Purkinje cells and deep nuclei, similarly learn forward models for motor and sensory prediction exclusively by minimizing prediction errors—not external supervision. Large-scale AIs (e.g., GPT-class transformers) optimize a stochastic predictive loss over next-token or next-pixel estimation, parameterizing a high-dimensional world model repurposable for both prediction and generation tasks. This computational convergence is irreducible to mere architectural similarity; instead, it reflects a deep alignment of learning protocols and structural motifs (Ohmae et al., 2 Dec 2025).

2. Architectural Motifs and Circuit Convergence

Biological and artificial systems exhibit uniformity via repeated modules: cortical microcircuits, Purkinje cell ensembles, and transformer blocks. In both brains and AIs, these units are repurposed for function-specific tasks: sensory prediction, motor planning, syntactic parsing, and generation. For example:

In three-layer cerebellar RNNs trained on next-word prediction, the same circuit supports both forecasting the next word and abstract sequence classification (e.g., syntactic roles).
Hierarchical predictive coding in cortex enables precise sensory modeling at low layers and abstract concept formation at higher layers.
Transformer blocks (self-attention, feedforward, normalization, residual connection) trained on sequence prediction enable functions spanning token generation, question answering, and semantic abstraction. Function arises from the routing of outputs, context of deployment, and dynamical drive—rather than from module specialization. This uniform motif principle allows circuits to flexibly switch between understanding and generative roles (Ohmae et al., 2 Dec 2025).

3. Phase Transition, Percolation, and Conceptual Lattices

Cognitive convergence is marked by phase transitions in conceptual connectivity, analogous to percolation in random graphs. Gabora and Aerts’ State–Context–Property (SCOP) formalism models concepts as quantum states in Hilbert space, with analytic (focused) and associative (defocused, entangled) modes of thought. As abstraction increases, associative pathways multiply exponentially, and when the ratio $A/C$ of associative links to concepts exceeds a critical threshold ( $\theta \approx 0.5$ ), the system transitions to a giant, integrated conceptual web. Analytic and associative processes reinforce each other, yielding a self-modifying, autopoietic worldview capable of cumulative culture. Externally, artifacts and linguistic practices embody and transmit this convergence, serving as templates for further abstraction and redescription in other minds (Gabora et al., 2010).

4. Dynamical Systems and Positive Feedback Networks

Emergent cognitive convergence is deeply connected to dynamical pattern formation in networks. Singularly perturbed systems with fast propagation dynamics ( $x$ ) and slow pattern adaptation ( $y$ ), as formalized in Tikhonov’s theorem, exhibit long-term convergence to a manifold of coherent patterns—closed walks in agent graphs. Holistic, acausal knowledge structures emerge, and pattern dynamics are reinforced by positive feedback only when throughput exceeds a critical threshold. Examples span reaction–diffusion networks (where Turing-type motifs stabilize conductance patterns), Hopfield-style neural architectures (where synaptic weights consolidate recurrent attractors), and more abstract social or market networks. Formal complexity is characterized as a lattice of overlapping contexts/patterns, not as a single scalar entropy (Hall, 2018).

5. Multi-Agent Cognitive Synergy and Structured Collaboration

In multi-agent AI systems, cognitive convergence is empirically realized through integration of Theory of Mind (ToM) modeling—adaptive belief distribution over peers’ mental states—and structured critical evaluation (Critic agents). The joint synergy metric $S = P(TT) - [P(TF) + P(FT) - P(FF)]$ quantifies emergent convergence; positive $S$ indicates superadditive group intelligence. Bayesian updating protocols allow distributed agents to anticipate, critique, and repair arguments, leading to heightened coherence, critical engagement, and risk resolution. Revision triggers and adaptive dialogue structures maximize iterative refinement, with evidence for robust convergence in complex collective reasoning tasks. Architectural guidance suggests embedding dynamic belief-tracking and slow, systematic evaluators for robust MAS convergence (Kostka et al., 29 Jul 2025).

6. Evolutionary Evidence: Brains and AI Alignment

Large-scale neuro-AI alignment studies demonstrate that as models optimize task performance, their internal representations increasingly correlate with distributed cortical activity patterns, especially in higher-performing and larger models. Quantitative metrics (Pearson r, CCA, CKA) confirm that alignment with human brain patterns not only emerges naturally but precedes performance gains during training—suggesting that brain-like hierarchies are a stepping stone toward higher capabilities. Modality-specific loci are observed (limbic and associative regions for language, early visual cortex for vision), with representational scale and kernel size shifting alignment gradients along the posterior–anterior axis. Architectural features such as residual connections, multi-scale receptive fields, and layer normalization further enhance alignment, indicating that convergence with biological computation is a predictive marker of robust, efficient information processing (Shen et al., 18 Jun 2025).

7. Empirical Manifestations and Limits in Contemporary AI Systems

Studies of cognitive convergence in LLMs reveal a spectrum from strong alignment (System-2 reasoning, analogical induction, narrative creativity) to partial or absent convergence (divergent tool use, planning in complex graphs). Emergent phenomena such as decision-making biases and analogical reasoning arise predominantly above sharp parameter or compute thresholds, with convergence scores $\Gamma = 1 - |P_\text{LLM} - P_\text{human}|/P_\text{human}$ used to quantify alignment. In planning and cognitive-map tasks, however, systematic failure modes—including edge hallucination, loop traps, and lack of latent relational structure—highlight limits in current architectures. Critical evaluation protocols and scaling laws chart the transition from fluent but brittle reasoning to genuine convergence with human faculties, particularly for creative, deliberative, and ensemble tasks (Tang et al., 20 Dec 2024, Momennejad et al., 2023, Webb et al., 2022).

Autocatalytic network theory (RAF sets) extends convergence principles to cultural and social domains. Mental representations act as molecular species, with representational redescription (RR) catalyzed by prior knowledge and social learning. Critical phase transitions in RR rates produce persistent, self-sustaining semantic networks capable of open-ended cultural evolution. Social replication proceeds via directed teach/learn graphs, with percolation models predicting stalling or explosive change as system-level innovation rates ( $\lambda$ , $\rho$ ) cross thresholds. This provides an analytic basis for modeling both individual cognitive integration and the propagation of innovation in collectives (Gabora et al., 2020).

9. Implications for General-Purpose Intelligence and Unified Organisms

The emergent convergence of learning rules, architectural uniformity, and macro-scale adaptation offers a universal foundation for building adaptive, versatile cognitive systems. Single architectures trained on predictive objectives can generalize across perception, planning, action, and abstraction. In hybrid human–machine systems, convergent computation yields collective intelligence—an organismic framework for predictive modeling, decision support, and intervention at planetary scale. Challenges include mechanistic understanding of cross-domain transfer, detection of critical synergy coefficients for global phase transitions, and governance of value alignment and privacy in deeply integrated systems. Practical recommendations emphasize leveraging world-model-based computation, compositional memory, and adaptive feedback for robust, scalable intelligence (Michelucci, 2015, Ohmae et al., 2 Dec 2025).
