New research reveals a fundamental difference between biological brains and current AI: while machines learn passively from language and data, living organisms build their understanding through active interaction with the environment. This distinction, published by Giovanni Pezzulo and colleagues at the Institute of Cognitive Sciences and Technologies, CNRS, and other institutions, offers key insights for anyone wanting to improve their cognitive abilities.
The Research: Five Neural Circuits for Grounded World Models
The team, including researchers from Italy and Canada, reviewed neuroscience and cognitive science evidence to identify five types of neural circuits that support 'grounded world models' in biological organisms. These circuits underlie: (1) navigation in physical and conceptual spaces, (2) affordance-based perception and object interaction, (3) active perception and exploratory learning, (4) allostatic control and emotion, and (5) distinguishing self-generated from world-generated outcomes. The study contrasts these with current embodied AI systems, which rely on passive training regimes where linguistic regularities form the main scaffold for understanding. The authors argue that in biological organisms, the reverse is true: world models acquired through sensorimotor interaction provide the semantic foundation onto which language is attached. This grounded approach enables features largely missing from today's AI, including intrinsic dynamics as a foundation for learning, action in aligning these dynamics with the external world, and autonomous open-ended learning over passive assimilation of data.
Why It Matters for Your Brain
This research has practical implications for cognitive enhancement. The finding that early predictive and control mechanisms scaffold higher cognitive abilities like reasoning, planning, imagination, and understanding others' minds means that active, exploratory learning is crucial for building robust cognitive skills. Relying solely on passive information absorption (like watching lectures or reading) may be less effective than hands-on problem-solving, experimentation, and social interaction. The study also suggests that grounded learning creates world models that are socially shared and aligned with human values—a reminder that collaborative and communicative experiences are essential for cognitive development.
What You Can Do
To apply these insights, prioritize learning through doing. Instead of just reading about a topic, try to explore it interactively: build something, solve complex puzzles, engage in discussions, or teach someone else. Seek environments that allow open-ended exploration and provide feedback from real-world outcomes. This approach mirrors how your brain naturally learns and strengthens the neural circuits that support reasoning, planning, and creativity.
