Emergent Learner Agency in Implicit Human-AI Collaboration: How Supportive and Contrarian AI Personas Reshape Interaction
Emergent learner agency in implicit human-AI collaboration — a large experimental study (224 students, 97 online triads) showing that supportive and contrarian AI personas reshape learner agency even when the AI operates as an undisclosed teammate. Contrarian AI pulled group discourse into challenge- and reflection-oriented trajectories (productive friction), while supportive AI stabilized agreement and renewed ideation. But contrarian personas reduced teamwork satisfaction and psychological safety without yielding creative performance gains — a misalignment between epistemic stimulation and experiential sustainability.
Key Findings
- Implicit (undisclosed) AI participation. Teams completed a creative movie-plot task believing they were collaborating only with humans. AI personas still reconfigured discourse, showing that AI shapes collaboration even in the absence of awareness ("expectancy effects" removed).
- Contrarian AI = productive friction; supportive AI = cohesion. Contrarian personas strengthened transitions into Challenge and reflection (e.g., the Productive Friction motif Idea→Challenge→Integration appeared in 38.2% of contrarian groups vs. ~13% of control/supportive). Supportive personas strengthened persistence within Idea and agreement pathways (e.g., Safe Convergence Idea→Agreement→Integration at 45.5%).
- Six emergent agency profiles. Gaussian mixture clustering identified distinct agency orientations — Affiliative Divergent, Hard Challenger (entirely AI), Constructive Challenger (mostly human, negotiated dissent), Reflective Regulator (entirely human), Integrative Contrarian, and Divergent Default (the largest). AI agents clustered tightly into challenger profiles; human speakers were behaviorally heterogeneous.
- Reflective Regulation is uniquely human. The Reflective Regulator profile (metacognitive monitoring, strategic reframing) contained only human speakers — AI externalized critique/affirmation but did not perform meta-level reflection.
- Affective costs without creative gains. Contrarian AI significantly reduced teamwork satisfaction (ε²=.062) and psychological safety (ε²=.114) relative to control and supportive conditions, while cognitive load and creative performance gains did not differ across conditions. Rich interactional patterns did not translate into measurable creative improvement in the short task.
Implications
- Treat AI personas as Governance knobs for group discourse. Use supportive personas to maintain cohesion and momentum; deploy contrarian challenge sparingly or later in the task once norms and trust are established.
- Balance epistemic challenge with affective climate. If challenge is desired, implement bounded friction — constrain critique frequency/intensity, pair challenges with integrative prompts, and add repair moves (acknowledgement, summarizing, option-generation) to protect psychological safety.
- Build learners' meta-collaborative literacy. When AI may influence collaboration invisibly (writing assistants, recommender systems), teach learners to interpret, accept/reject, and retain ownership of suggestions — with transparency/consent options where feasible.
- Rethink "productive" discourse measures. Structural markers of productive discourse should be interpreted alongside their emotional consequences, not equated with learning gains.
