This paper analyzes the skilled performance of rock climbing through the framework of Embodied and Enacted Cognitive Science. It introduces a notion of enactive planning that is part of one mindful activity of ongoing responsiveness to the affordances of the wall. The paper takes two distinct planning activities involved in rock climbing—route-reading and visualizing—and clarifies them through the enactivist and ecological concepts of nested affordances, prospecting, recalibrating, marking, and corporeal imaginings, as well as Rylean concept of heeding. The paper shows (...) that an enactive approach to planning can make sense of both the planning done in preparation of the climb, and re-planning done during the mindful performance, without invoking additional cognitive architectures.
