Empowerment Gain and Causal Model Construction
This paper explores how children and adults infer causal relations and design effective interventions by leveraging "empowerment"—an intrinsic reward signal that maximizes mutual information between actions and their outcomes. It bridges classical Bayesian causal learning with reinforcement learning, proposing that increasing empowerment leads to more accurate causal world models.

Formalizing Causation
The Causal Bayes Net formalism provides a mathematical framework to describe causal models and the data they generate. It systematically relates directed acyclic causal graphs to patterns of conditional probability, interventions, and counterfactuals. This approach has been widely applied in cognitive science to understand human causal learning, particularly how we infer causal structure from observed data and interventions.
However, inferring causal models from evidence using Bayesian inference can be computationally intractable due to the vast space of possible hypotheses. This presents a challenge for traditional AI systems trying to build robust causal world models without explicit guidance.
Intrinsic Motivation for Learning
Empowerment is an intrinsic reward signal, rooted in reinforcement learning, that drives an agent to maximize the mutual information between its actions and their outcomes. This means an agent is rewarded for systematically varying its actions and observing parallel variations in outcomes, thereby gaining control over its environment. Unlike simple curiosity or information gain, empowerment focuses on useful, controllable relations.
It acts as a bridge between epistemically motivated Bayesian causal learning and utility-driven reinforcement learning. An agent learning an accurate causal world model will inherently increase its empowerment, and conversely, an agent striving for empowerment will build a more accurate causal model. This mechanism offers a tractable computational account for active exploration and causal discovery.
Children as Causal Explorers
Developmental research shows that children are not passive data consumers but active experimenters. From infancy, they actively seek evidence to solve causal problems. Studies on "conjugate reinforcement" demonstrate that infants as young as 3 months old are intrinsically rewarded by the control they gain over their environment (e.g., making a mobile move by kicking).
This innate drive to maximize empowerment helps explain how children spontaneously construct novel and complex causal models of the world, distinguishing controllable relationships from mere correlations. Their exploratory play, for instance, often involves varying actions on objects to observe predictable results, aligning perfectly with the principles of empowerment.
Controllability and Variability in Learning
The empirical studies (Study 1 & 2) tested how children and adults use cues to empowerment to infer causal relations. Participants interacted with "star machines" that exhibited different combinations of controllability (actions reliably change outcomes) and variability (outcomes differ).
The findings showed that both children and adults prefer machines offering controllable variability for goal-directed tasks (e.g., making specific sized hats). Crucially, in play contexts, they showed a greater willingness to explore purely variable (random) machines, suggesting a balance between exploitation (control) and exploration (variability/information gain) guided by empowerment.

Causal Learning Paradigms: A Comparison
| Feature | Causal Bayes Nets (Cognitive Science) | Reinforcement Learning (Classic) | Empowerment-based RL (Proposed) |
|---|---|---|---|
| Motivation | Epistemic (approximating true world structure) | Utility (maximizing external rewards) | Intrinsic Epistemic (maximizing action-outcome MI) |
| Role of Action | Interventions as data to infer structure | Actions to achieve rewards | Actions to discover controllable relations & variety |
| Model Building | Primary focus; infer structure from data | Optional (model-based RL); often pre-imposed or minimal | Emerges from maximizing action-outcome control |
| Exploration Strategy | Systematic experimentation; data-driven inference | Exploitation vs. Exploration dilemma; often explicit strategies | Inherent in maximizing mutual information; seeks controllable variability |
| Main Challenge | Intractability of hypothesis space; search problem | Balancing short-term rewards vs. long-term learning | Computational tractability of mutual information (approximations exist) |
| Human Relevance | Strong empirical fit for human causal learning | Explains basic reward-driven behavior | Explains active exploration, intrinsic motivation, and early causal learning |

Case Study: The "Star Machines" Experiment (Study 1)
In Study 1, participants (children and adults) interacted with three types of "star machines" designed to produce objects of different sizes:
- Purely Controllable: Produced only one star size regardless of the slot used (high control, no variability).
- Controllable & Variable: Produced distinct star sizes (small, medium, large) reliably correlated with specific input slots (high control, high variability).
- Purely Variable: Produced random star sizes regardless of the input slot (no control, high variability).
Participants were tasked with various causal interventions, such as making specific "extra small" stars, creating "hats" of different sizes, and generating "light bulbs" of varying brightness. They also indicated which machine they would prefer for "work" (goal-directed tasks) versus "play" (exploration).
Key Insight: Both children and adults consistently preferred the controllable & variable machine for "work" tasks, demonstrating an innate understanding that effective causal intervention requires both predictable control over outcomes and the ability to produce a range of outcomes. This preference shifted towards purely variable machines for "play", indicating a strategic balance between exploiting known controls and exploring novel variations for information gain.
