Check out our preprint thread for more details!.
Human behavior is hierarchically structured. But what determines *which* hierarchies people use? In a preprint, we run an experiment where people create programs that correspond to hierarchies, finding that people prefer structures with more reuse. 1/7

My paper on hierarchical plans is out in Cognition!🎉. tldr: We ask participants to generate hierarchical plans in a programming game. People prefer to reuse beyond what standard accounts predict, which we formalize as induction of a grammar over actions.

Lightbot (@lightbotcom) was originally built by @dannyaroslavski. We build on an open-source version by @laurenthaan (. Animation in first tweet was inspired by M. C. Escher’s Ascending and Descending and the game Monument Valley (by @ustwogames). 7/7.

Human behavior is often assumed to be hierarchically structured, made up of abstract actions that can be decomposed into concrete actions. However, behavior is typically measured as a sequence of...

We find that people have a bias towards reuse, beyond the reuse that naturally occurs when minimizing program length. Drawing from theories of word learning, we account for this by modeling participants' program-writing as if they were creating & using an action grammar. 4/7

Importantly, a program isn't just a sequence of instructions. Participants can define and use parts of programs (called processes), making it possible to write shorter, more compact programs. 3/7

We use a process-tracing paradigm where people create hierarchical plans. Based on the educational game @lightbotcom, research participants drag and drop instructions to write programs. Lightbot follows these instructions, with the goal of activating all lights. 2/7
