タウ、 オプティカルフロー、 アフォーダンス、 運転行動、 リスク式抄録
本稿の目的は,生態心理学の初学者に向けて,「タウ ( )」という概念を起点に,人間の知覚と行動を定量化し,数理モデルとして構築していく方法論 (How)を実践的に解説することである.自動車の運転行動を題材とし,実験室 (Lab)での基礎研究からリアルワールド (Road)での検証へと至る5つのステップを紹介する.具体的には,(1) 環境中の光学的変数 (オプティカルフロー)の特定,(2) 心理物理学的手法による主観的リスク感の測定,(3) 位相平面を用いた行動のモデル化とカップリング理論との統合,(4) アフォーダンスと満足化の概念による個人の多様性の包摂,そして(5) ナチュラリスティックな運転行動データ (NDS)を用いたモデルのリアルワールド検証である.本稿を通して,生態心理学的アプローチのダイナミズムとその実践的有用性を提示する.
