Gestures, but not meaningless movements, lighten working memory load when explaining math

Abstract

Gesturing is ubiquitous in communication and serves an important function for listeners, who are able to glean meaningful information from the gestures they see. But gesturing also functions for speakers, whose own gestures reduce demands on their working memory. Here we ask whether gesture's beneficial effects on working memory stem from its properties as a rhythmic movement, or as a vehicle for representing meaning. We asked speakers to remember letters while explaining their solutions to math problems and producing varying types of movements. Speakers recalled significantly more letters when producing movements that coordinated with the meaning of the accompanying speech, i.e., when gesturing, than when producing meaningless movements or no movement. The beneficial effects that accrue to speakers when gesturing thus seem to stem not merely from the fact that their hands are moving, but from the fact that their hands are moving in coordination with the content of speech.

TL;DR

Speakers recalled more letters while explaining math problems when they produced meaningful gestures than when they produced meaningless circular movements or kept still. The working-memory benefit of gesture therefore appears to depend on movement being coordinated with speech meaning, not merely on rhythmic hand movement.

Key findings

  • Participants were more likely to remember the six consonants when gesturing during explanations than when producing meaningless movements (β = −.17, z = 3.23, p < .01) or no movement (β = −.13, z = 2.61, p < .01).
  • The gesture advantage held in a between-subjects analysis limited to each participant’s first condition: meaningless movement β = −.30, z = 1.90, p = .057; no movement β = −.36, z = 2.30, p = .02.
  • Instructed gesturing produced more gestures than spontaneous gesturing in prior work: mean 13 gestures, maximum 88, versus mean 6, maximum 33 in Wagner et al. (2004).
  • Meaningless movement affected verbal production—more words (52.8 vs. 46.9 meaningful, 46.3 no movement) and fewer non-juncture filled pauses (.16 vs. .24 meaningful, .26 no movement)—but these verbal measures did not account for the working-memory benefit.

Methods

  • 115 college students (62 females; mean age = 19.6 years) solved 30 quadratic factoring problems, then held six consonants in memory for 2.5 seconds while explaining their solutions under instructed conditions: meaningful movement/gesture, meaningless circular movement, or no movement.
  • Because pilot testing showed three instruction changes were difficult, each participant completed two of the three conditions, yielding three groups; order was counterbalanced, and problems and memory lists were randomized.
  • Recall of each of the six letters was analyzed with multilevel logistic regression including condition and trial as fixed effects and subject, math problem, and working-memory list as random effects; verbal explanations were also analyzed with multilevel regression.

Limitations

  • The paper states that the gestures produced were primarily deictic and directed at visible entities, so findings might be restricted to gestures that point out objects in the immediate environment, though it cites other work suggesting the benefit may not be limited to such gestures.
  • The paper states that the data do not pinpoint a mechanism for gesture’s working-memory benefit, only narrowing it to mechanisms involving gesture as a vehicle for meaning.
  • Evident from the text: participants were college students performing a specific math-factoring task, gesture was experimentally instructed rather than spontaneous, and each participant completed only two of three conditions, which may limit generalizability and full within-subject comparison.

    “It has been shown that making gestures can be used for cognitive offloading of information during problem-solving, leading to a reduction in working memory load (Wagner-Cook et al. 2012; Goldin-Meadow et al. 2001; Ping and Goldin-Meadow 2010; Risko and Gilbert 2016).”

    The Discussion reports that gesturing reduces demand on working memory during math explanations. But in “How does gesture lighten the load? Potential mechanisms,” externalizing information is presented as a possibility, and the authors explicitly say their data do not pinpoint the mechanism. The claimed cognitive-offloading explanation is therefore not established by this paper. (LLM, conf=0.88)

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.
