This document discusses recent developments in causal inference methods. It contains summaries of talks on several causal inference topics:
1. Miguel Hernan discusses the g-formula approach and inverse probability weighting for estimating causal effects under confounding.
2. Judith Lok discusses marginal structural models and g-estimation of structural nested models for longitudinal data, which allow controlling for time-varying confounding.
3. James Robins discusses single world intervention graphs for representing counterfactuals and the g-formula for estimating effects of dynamic treatment regimes.
4. Tyler VanderWeele discusses approaches for causal mediation analysis, including the difference method and natural direct and indirect effects.

11. 今後の展望 Future Directions
• 新たな計算機的方法の模索new computational approach
• 同時間の同期だけではなく、時間のずれたlags同期(leader-follower dynamics)
• 交流への関わりや維持を含めたダイナミックな関係性
• 脳同士の補完的役割(a calm parent – an anxious child)
• まだ発見されていない時間的・空間的同期
• フィードバックループ:交流によってもたらされた共通の意識による関係修飾(a shared
language and shared norms that are themselves the product of social
interactions)
• 生態学的妥当性の向上toward more ecological validity
• より自然な状況での交流における測定を目指す
