## Summary  
The paper investigates how incorporating think‑aloud language traces can improve the discovery of automated cognitive models beyond what is possible using behavioral data alone. By treating these verbal reflections as additional constraints, the authors demonstrate that model fitting improves and that the structural form of the recovered models changes systematically. The work shows that process‑level linguistic information not only yields better predictive performance but also reshapes the underlying cognitive architecture that large language models infer. This dual benefit—enhanced fit and novel mechanistic insight—highlights a gap in current automated discovery pipelines.

## Key Contributions  
- [Finding 1] Adding think‑aloud traces as constraints significantly improves predictive performance on held‑out risky decision‑making data compared with models built only from behavioral trajectories.  
- [Finding 2] For the majority of participants (69.4 %), the cognitive models recovered include a shift from an “Explicit comparator” structure to an “Integrated utility” structure, indicating a systematic re‑orientation of model architecture.  
- [Finding 3] Process‑level language data enables the identification of mechanisms that are not recoverable from behavior alone, thereby expanding what can be inferred about underlying cognitive processes.

## Methodology  
The authors employ automated cognitive model discovery using large language models (LLMs) trained to generate latent representations of decision‑making processes. First, they collect standard behavioral data for participants making risky choices and also record think‑aloud verbalizations during the same task. The think‑aloud traces are parsed into structured constraints that guide the LLM’s inference process. Models discovered from behavior alone serve as a baseline; those incorporating think‑aloud constraints are then compared on held‑out test sets to assess fit and structural differences.

## Results  
Experimental results show that models built with think‑aloud constraints achieve markedly higher accuracy (p < 0.01) than the behavioral‑only models. A statistical analysis of model structures reveals a 69.4 % shift from explicit comparator frameworks—where decisions are judged against fixed criteria—to integrated utility frameworks—where outcomes emerge from combined value assessments. The latter class better predicts novel scenarios, confirming that think‑aloud data reshapes both performance and architecture.

## Significance  
This study demonstrates that augmenting automated discovery with process‑level language traces yields not only improved fit but also a reconfiguration of the inferred cognitive model, unlocking insights inaccessible to behavior‑only approaches. By bridging behavioral outcomes with explicit mental reasoning, the work opens pathways for more mechanistic explanations in AI‑driven cognitive modeling.
