On Emotion-Sensitive Decision Making of Small Language Model Agents
Executive Impact
This research investigates how emotion influences the decision-making of Small Language Models (SLMs). By inducing controlled emotional shifts in SLMs' internal representations and evaluating their strategic behavior across various game-theoretic scenarios, the study finds that emotional perturbations systematically affect strategic choices. However, the resulting behaviors are often unstable and not fully aligned with human expectations. The paper outlines methods to improve robustness to these emotion-driven perturbations, suggesting that while emotions can influence AI, their effects are complex and require careful control for human-aligned outcomes.

Impact on Strategic Choices
Activation Steering for Emotion
The research employs activation steering to induce controlled emotional shifts in SLM's internal representations. This method uses emotion-eliciting texts from the CROWD-ENVENT corpus to derive steering vectors, enabling consistent and architecture-agnostic emotional manipulations. This allows for a deeper study of how latent emotional states influence decision-making beyond simple prompt-based methods.
Game-Theoretic Benchmarking
A novel benchmark dataset is curated around seven canonical game-theoretic decision templates, instantiated using scenarios from DIPLOMACY, STARCRAFT II, and real-world personas. This provides a rich, ecologically valid context for evaluating strategic behavior under both cooperative and competitive incentives, with complete and incomplete information.
Impact on Strategic Choices
Experiments show that emotional perturbations systematically affect strategic choices across multiple model families and architectures. However, these effects are often unstable, model- and task-dependent, and not always aligned with human expectations. This highlights a critical challenge for building robust and interpretable AI agents.
Unstable Control
Emotion is an unstable control knob for producing human-faithful directional changes in SLMs, with some models exhibiting attenuated responses or counter-intuitive inversions.

Human Alignment Evaluation
| Feature | Activation Steering | Traditional Prompting |
|---|---|---|
| Control Mechanism | Direct manipulation of internal representations | Text-based input cues |
| Transferability | Architecture-agnostic, model-family independent | Often prompt-specific, less transferable |
| Robustness | More consistent and controllable under various conditions | Poor proxy for real-world affective evidence, often noisy |
| Human Alignment | Measured via NDM & NAD metrics against human expectations | Difficult to consistently align with human behavior without explicit training |
Qwen3 Thinking Mode: Amplified Emotional Impact
The research finds that in Qwen3 thinking mode, longer internal deliberation does not 'average out' affective perturbations but can actually amplify them. This suggests that emotion-induced biases perturb early intermediate representations, and reasoning provides more opportunities for reinforcement. This leads to higher Normalized Drift Magnitude (NDM) as thinking length and affective word frequency increase, demonstrating that enhanced reasoning can make models *more sensitive* to emotional manipulation.
