On Distinguishing Epistemic from Pragmatic Action
Open accessAbstract
We present data and argument to show that in Tetris—a real‐time, interactive video game—certain cognitive and perceptual problems are more quickly, easily, and reliably solved by performing actions in the world than by performing computational actions in the head alone. We have found that some of the translations and rotations made by players of this video game are best understood as actions that use the world to improve cognition. These actions are not used to implement a plan, or to implement a reaction; they are used to change the world in order to simplify the problem‐solving task. Thus, we distinguish pragmatic actions—actions performed to bring one physically closer to a goal—from epistemic actions—actions performed to uncover informatioan that is hidden or hard to compute mentally. To illustrate the need for epistemic actions, we first develop a standard information‐processing model of Tetris cognition and show that it cannot explain performance data from human players of the game—even when we relax the assumption of fully sequential processing. Standard models disregard many actions taken by players because they appear unmotivated or superfluous. However, we show that such actions are actually far from superfluous; they play a valuable role in improving human performance. We argue that traditional accounts are limited because they regard action as having a single function: to change the world. By recognizing a second function of action—an epistemic function—we can explain many of the actions that a traditional model cannot. Although our argument is supported by numerous examples specifically from Tetris, we outline how the new category of epistemic action can be incorporated into theories of action more generally.

Written from the paper’s full text.
TL;DR
The paper argues that Tetris players perform some rotations and translations not to advance a physical goal but to simplify cognition, introducing epistemic actions as distinct from pragmatic actions. A classical sequential information-processing model and an interleaving variant fail to explain extra rotations and translate-to-wall routines, which are better explained as actions that uncover information, reduce mental rotation, or verify placement.
Key findings
- Players rotate zoids more than expected for purely pragmatic placement: each zoid is rotated more than half its possible rotations; for a shape with four distinct orientations, the expected average would be 1.5 rotations, but observed rotations exceed this. Rotations sometimes begin before 100 ms, before the zoid is fully visible.
- Early rotation can expose hidden parts 150 to 300 ms earlier than waiting for natural appearance; partially hidden zoids ambiguous in both shape and position are more likely to be rotated than those ambiguous in shape alone, though no player reported noticing that zoids begin falling in different columns.
- Physical rotation of a zoid 90° can take as few as 100 ms, whereas mental rotation of a zoid 90° is estimated at 800 to 1200 ms. The translate-to-wall verification routine occurs in about 1% of drops; experts drop a zoid on average 15.65 squares from resting position ordinarily versus 20.05 squares after the translate routine, with intermediate players 13.18 versus 19.04 and advanced players 13.69 versus 19.33.
- The translate-to-wall routine moves the zoid away from the intended column, so it cannot be a pragmatically good move; its function is to verify the column and reduce error, and higher drops are more likely to be verified this way.
Methods
- Design: Tetris was used as a real-time, interactive video game domain; the authors implemented a computational laboratory to unobtrusively record the timing of all keystrokes and game situations, collected tachistoscopic mental rotation tests, and designed and implemented the RoboTetris expert system to compare human and machine performance.
- Sample: the mental rotation pilot had three Tetris players—one intermediate, one advanced, and one expert—each seeing eight presentations of each possible pair of L-shaped or S-shaped zoids; human gameplay data came from subjects playing Tetris.
- Analysis: a classical four-phase information-processing model was constructed (bitmap representation, chunked symbolic representation, placement computation, motor plan computation), then relaxed to allow cascade/interleaving; model predictions such as expected rotation counts were compared with observed keystroke timing and frequency, and deviations were interpreted as epistemic actions.
Limitations
- The paper states it is often hard to prove that an agent performs a particular action for epistemic rather than pragmatic reasons, because an action can serve both epistemic and pragmatic purposes simultaneously, making the relative influence difficult to quantify.
- The paper states it is an open question whether agents use multiple-perspective representations of zoids; the mental rotation data are described as pilot data from only three players, so the mental rotation time estimates are preliminary.
- Evident from the text: many epistemic interpretations are inferred from timing and behavioral regularities rather than direct experimental manipulation, and the mental rotation comparison rests on a very small sample.

“…human problem solving behavior, which, as Vera and Simon accept, often involves interactions with the environment whose role is epistemic (Kirsh and Maglio 1995), i.e. part of the problem-solving itself (aimed for instance at simplifying the problem at hand, as when a puzzle piece is…”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
A language model drew the claims from the paper on 2026-10-12, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).
A second model labelled each claim on 2026-10-12 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
