Mind in Motion
Tversky's 2019 synthesis of four decades of research on spatial cognition — the book that argues action shapes thought and that the mind extends through tools and representations.
Mind in Motion: How Action Shapes Thought (Basic Books, 2019) presents the synthesis of Tversky's research program: the claim that human cognition is fundamentally spatial and embodied, that we think through our bodies and through the external representations we construct, and that action — moving, gesturing, sketching, arranging — is not downstream of thought but constitutive of it. The book articulates nine laws of cognition that together replace the image of the mind as a sealed processor with the image of the mind in continuous engagement with space, body, and artifact.

Tversky's laws formalize this insight: the mind fills in missing information,
