# Role-Sensitive Control in Collaborative AI

Role-sensitive control refers to computational frameworks, algorithms, and interaction protocols that explicitly model, monitor, and update the internal representations ("mental models") of multiple interacting agents according to their respective roles within a collaborative task. These representations guide the agents' explanations, actions, and joint policies with the goal of achieving mutual understanding, effective coordination, and dynamic adaptation—particularly in settings where one or more agents are artificial (e.g., robots, AI systems) and where the content, granularity, or sequencing of information and interventions depend sensitively on the agents’ role-specific knowledge states. Recent work operationalizes this concept through sequential explanation policies, interactive reconciliation of agent and user models, after-action review systems, and spatially-anchored visualizations—all focused on aligning and tuning internal states across agent roles to achieve demonstrable gains in team performance, learning efficacy, and trust calibration.

## 1. Foundational Concepts: Mental Model and Shared Mental Model Dynamics

At the core of role-sensitive control lies the notion of a mental model—an agent’s internal representation of the relevant aspects of the world, task, and its teammates. In human–AI teaming contexts, the intersection or alignment of these models becomes the shared mental model (SMM), whose growth or maintenance is both a theoretical and practical objective [2503.19607, 2503.07547].

Several frameworks formalize individual mental models as sets of task-relevant facts $F = \{f_1, ..., f_K\}$, with each agent $i$’s model at time $t$ given by $c_t^i \subseteq F$ or equivalently a binary vector $m_t^i \in \{0,1\}^K$. Joint policies derive from both self-models and predictions of other agents' models, yielding $\pi^i$ (self-policy) and $\pi^{i(j)}$ (agent $i$’s estimate of agent $j$’s policy) [2503.07547].

The shared mental model is thus the degree of overlap or alignment in the sets $c_t^i$ across agents, with formal metrics such as set edit distance $d_c(c^1, c^2) = |c^1 \Delta c^2|$ or divergence of policy distributions (e.g., $L_1$ or KL divergence). SMM growth ($G(t)$) is quantified as the reduction in these discrepancies over time or episodes, directly reflecting the efficacy of role-sensitive interventions [2503.19607].

## 2. Sequential Explanations and Mental Model-Based Policies

A central paradigm for role-sensitive control involves the stepwise adaptation of explanations and pedagogical signals to the evolving mental models of target agents. Yeung et al. formalize this as a dynamic loop: at each turn $t$, the explainer observes a representation $s_t = [\mathrm{sat}_t, \mathrm{sim}_t^{TP}, \mathrm{sim}_t^{TN}, \mathrm{sim}_t^{FP}, \mathrm{sim}_t^{FN}]$, where $\mathrm{sat}_t$ is self-reported satisfaction and $\mathrm{sim}_t^{c}$ is simulatability for each outcome class $c$ [2007.09028].

Explanatory actions $a_t$ are selected from a discrete set (e.g., prototype or saliency-based visualizations, each type specific to a class outcome). The choice of action is determined by greedy policies that target the specific dimensions of $s_t$ where user proficiency is weakest, thereby optimizing an interpretability reward (sum of simulatability scores). Over multiple iterations, this leads to measurable increases in both local simulatability and global SMM alignment, especially when policy choice is sensitive to the role-specific weaknesses and preferences of the explainee (e.g., switching explanation type if satisfaction drops) [2007.09028].

## 3. Bi-Directional Mental Model Reconciliation Protocols

Effective role-sensitive control requires not only the explainer to adapt but also support for two-way correction and hybridization of models between agents. In the framework of bi-directional mental model reconciliation [2503.07547], both human and robot agents maintain explicit, fact-based models and engage in dialogue whenever discrepancies between predicted and observed actions arise. The reconciliation algorithm iteratively launches semi-structured natural-language exchanges, parsed by a large language model to extract missing facts, which are then added to the appropriate agent’s context set.

The process iterates until policy divergences ($d_\pi$) between actual and predicted behaviors for both agents fall below a pre-defined threshold. Update operators $U$ apply set-union of fact sets and re-plan policies accordingly. This loop enforces role-sensitive symmetry: neither agent is privileged as "ground truth," and both can supply and absorb missing context in a controlled, convergence-guaranteed manner. Quantitative evaluation demonstrates that such protocols sharply reduce inter-agent fact and policy edit distances, accelerate team task completion, and improve subjective trust and workload measures [2503.07547].

## 4. Shared Mental Model Alignment Tools and Testbeds

Role-sensitive control is further operationalized in instrumented environments that scaffold deliberate SMM development. Gu et al. present an After-Action Explanation (AAE) tool within a browser-based Minecraft testbed [2503.19607], unifying synchronized video replay (from all agent perspectives), explicit mission context documents, fully timestamped event logs, and a GPT-4–augmented chat interface for querying and explaining agent decision policies.

This infrastructure supports systematic post-mission review, enabling participants to interrogate role-specific surprises (e.g., unexpected agent phase switches) and iteratively align their models through rich, context-aware feedback. Formal evaluation protocols measure SMM growth using alignment accuracy (agreement between participant prediction and actual agent action), KL-divergence between predicted and actual policy distributions, and classical task metrics (build completion time, fluency, situational awareness accuracy).

Ablation and sensitivity analyses on such testbeds isolate the value of each explanation modality, while browser-based deployment accelerates research iteration in collaborative, partially observable environments [2503.19607].

## 5. Cartographic Visualization for Role-Specific Cognitive Anchoring

Spatial and cartographic approaches to SMM—particularly CODEMAP in software engineering [1001.2386]—embed a continuous, stable spatial representation of system structure into the workflow of collaborating teams. By mapping code artifacts to 2D coordinates using blended lexical and structural dissimilarities and rendering these as cartographic terrains (with overlays reflecting bug density, coverage, and active users), teams acquire a persistent, role-agnostic frame of reference.

Such visualizations enable role-based indexing of system regions and navigation (e.g., newcomers addressing UI code in the “east,” security teams locating authentication logic “north”), reinforcing communal model coherence through spatial cues and thematic overlays. Metric-based and landmark-driven spatial consistency minimize layout drift, supporting long-term SMM stability despite codebase evolution. Empirical studies show increased mental model congruence and navigation efficiency, particularly for less-experienced team members, though adaptation costs exist for experts [1001.2386].

## 6. Formal Metrics, Evaluation Methodologies, and Experimental Findings

Advances in role-sensitive control are characterized by rigorous use of quantitative and qualitative metrics:

- **Model and policy divergence:** Set edit distance $d_c$, $L_1$ or KL divergence on action or policy distributions.
- **SMM growth:** Improvement in alignment accuracy (fraction of correctly predicted teammate actions), and reduction of $D_{KL}$ or $d_\pi$.
- **Subjective outcomes:** Likert-scale trust, NASA-TLX workload, explanation satisfaction.
- **Task outcomes:** Completion/integration time, fluency measures (redundancy, handoffs), error counts.

Pilot and full-scale studies consistently indicate that role-sensitive, model-aligned protocols—especially those incorporating interactive, explanation-rich, and bidirectional mechanisms—yield substantial improvements in mental model alignment, task performance, error minimization, and participant trust relative to random, static, or solely unidirectional strategies [2007.09028, 2503.07547, 2503.19607, 1001.2386].

## 7. Limitations and Future Directions

Despite substantial empirical and methodological advances, several open challenges remain. Purely greedy (γ=0) or heuristic explanations lack principled convergence guarantees, particularly in heterogenous real-world settings [2007.09028]. Current testbeds are often constrained to post-hoc alignment, with limited real-time adaptation [2503.19607]. While LLM-mediated reconciliation is effective in task-oriented dialogue, robustness to noise and scale-out to multi-agent, multi-human scenarios are active areas for exploration [2503.07547].

Future work involves integrating richer observational signals (trust, cognitive load) into agent state, online/in-mission adaptation, automated mining of policy corrections from after-action transcripts, and validation across more diverse domains and roles. Persistent anchoring and longitudinal studies are needed to establish the durability and transferability of role-sensitive SMM growth strategies in large, dynamic teams [2007.09028, 2503.19607, 1001.2386].
