q2 i? Across similar topic complexity levels with interaction duration controlled, curiosity-modulated interactions produced roughly 2.4× more conversational turns than Baseline (overall means 6.66 vs 16.12), with turn counts increasing by approximately 2–3× throughout. → Ganganath 2026

q2 · i? · causal · r2

Engagement-depth analysis (§5.1) across 270 conversations reported in Table 2: overall mean turns 6.66 (Baseline) vs 16.12 (CURIOBOT), with per-condition means ranging from 4.74 to 20.00. Descriptive means reported; no inferential test statistic printed for this contrast.

"Table 2 shows that, across similar topic complexity levels (with interaction duration controlled by time spent in dialogue), curiosity-modulated interactions produced roughly 2.4× more conversational turns than Baseline."

Discussion¶

Learner Variables¶

• Interest — predictor: learners who differ on it differ in outcomes

Related Claims¶

• Curiosity-oriented linguistic interventions via CURIOBOT consistently improve all learner-side exploratory dimensions relative to baseline LLM tutoring across model families — related
• Learner-side gains from curiosity modulation generalize across model families, academic domains, and topic complexity levels — related
• Learner-side gains from curiosity modulation persist even when tutor-side instructional quality remains unchanged or degrades, suggesting curiosity operates as a partially independent interaction-level mechanism — related
• Voice modality roughly doubled dialogue turns and question-asking on equal engaged time within the same students — related
• The number of conversational turns is more closely associated with children's language skills and language-related brain function than the raw number of words heard, regardless of family income or education. — related
• Trained students engage in more conversational turns with the GenAI tool — related
• Curiosity gains depend on operator sequencing: how operators are ordered across turns, not only which operator is applied, shapes curiosity induction — related
• Commercially optimized study-oriented modes achieve higher learner-side scores than baseline, and CURIOBOT shifts general-purpose LLM behavior toward those patterns via prompting alone — related
• Students who engaged more meaningfully with the GenAI tended to have more sustained interest than control students (exploratory) — related
