Do gestures merely reflect problem-solving processes, or do they play a functional role in problem solving? We hypothesized that gestures highlight and structure perceptual-motor information, and thereby make such information more likely to be used in problem solving. Participants in two experiments solved problems requiring the prediction of gear movement, either with gesture allowed or with gesture prohibited. Such problems can be correctly solved using either a perceptual-motor strategy…

Effects of Gesture on Analogical Problem Solving: When the Hands Lead you Astray
The results suggest that gestures can be detrimental to analogous problem solving when the perceptual elements of a story are irrelevant to its schematic similarity with a problem.
Co-thought gesturing supports more complex problem solving in subjects with lower visual working-memory capacity
Investigating whether gesticulation during silent problem solving supported subsequent performance in a Tower of Hanoi problem-solving task, in relation to visual working-memory capacity and task complexity found gesturing benefited complex problem-Solving performance for participants with a lower visualWorking-Memory capacity, but not for participantsWith a lower spatial working- memory capacity.
The Role of Gesture in Supporting Mental Representations: The Case of Mental Abacus Arithmetic
It is concluded that premotor processes involved in the planning of gestures are critical to mental representation in MA, a technique in which users not only imagine moving beads on an abacus to compute sums, but also produce movements in gestures that accompany the calculations.
In which direction to move? Facilitative and interference effects of gestures on problem solver's thinking
ABSTRACT Recent research shows that co-speech gestures can influence gesturers’ thought. This line of research suggests that the influence of gestures is so strong, that it can wash out and reverse
The Gesture-for-Conceptualization Hypothesis
A new theoretical framework, the Gesture-forConceptualization Hypothesis, is proposed, which explains the self-oriented functions of representational gestures, which are generated from the same system that generates practical actions, such as object manipulation; however, gestures are distinct from practical actions in that they represent information.
How Do Gestures Influence Thinking and Speaking? The Gesture-for-Conceptualization Hypothesis
A new theoretical framework is proposed, the gesture-for-conceptualization hypothesis, which explains the self-oriented functions of representational gestures, which are generated from the same system that generates practical actions, such as object manipulation; however, gestures are distinct from practical actions in that they represent information.
Co-thought gestures: Supporting students to successfully navigate map tasks
Gesturing was most influential when students encountered unfamiliar tasks or when they found the tasks spatially demanding, since students tended to not use gesturing in tasks where the spatial demands were low.
Instructed Hand Movements Affect Students' Learning of an Abstract Concept From Video
Two studies investigate the impact of instructed hand movements on students' subsequent understanding of a concept by finding that students in the content-match group performed better on the posttest, and showed less variation in performance, than did students inthe content-mismatch group, with control students falling in between.
Moving your Eyes to Solution: Effects of Movements on the Perception of a Problem-Solving Task
This study investigated participants’ gaze behaviour in the first phase of arithmetic problem solving with two groups to explore a spatial bias toward the left or the right while perceiving a problem-solving task, and showed a right shift of spatial bias for the plus and to the left for the minus group in the perception and problem tasks.
A new perspective on the cognitive function of gestures: The “spatializing” gesture hypothesis
: Human beings often make gestures when talking or thinking. Gestures are generated automatically during cognitive processing or communication, and as representations, they in turn affect human


The nature of gestures' beneficial role in spatial problem solving.
It is concluded that gestures enhance performance on spatial visualization tasks by improving the internal computation of spatial transformations and the benefit of gestures persists even in subsequent spatial visualization problems in which gesture is prohibited.
The Role of Gestures in Mental Animation
The results indicate that gestures are a natural way of expressing the results of mental animation processes and suggest that spatial working memory and premotor representations are involved in mental animation.
Gesture highlights perceptually present information for speakers
Why do speakers produce gestures? This study tests the hypothesis that gesture facilitates the conceptual planning of speaking, and in particular, gesture promotes thinking about perceptually present
Making children gesture brings out implicit knowledge and leads to learning.
Telling children to gesture encourages them to convey previously unexpressed, implicit ideas, which, in turn, makes them receptive to instruction that leads to learning.
Illuminating Mental Representations Through Speech and Gesture
Can the gestures people produce when describing algebra word problems offer insight into their mental representations of the problems? Twenty adults were asked to describe six word problems about
Gesture and the process of speech production: We think, therefore we gesture
At what point in the process of speech production is gesture involved? According to the Lexical Retrieval Hypothesis, gesture is involved in generating the surface forms of utterances. Specifically,
Gesture Changes Thought by Grounding It in Action
It is shown that gesture introduces action information into speakers’ mental representations, which, in turn, affect subsequent performance, and when gestures are no longer compatible with the action constraints of a task, problem solving suffers.
Visible embodiment: Gestures as simulated action
This work argues that gestures emerge from perceptual and motor simulations that underlie embodied language and mental imagery, and proposes the gestures-as-simulated-action framework to explain how gestures might arise from an embodied cognitive system.
Gestures maintain spatial imagery.
It is argued that spatial imagery serves a short-term memory function during lexical search and that gestures may help maintain spatial images when spatial imagery is not necessary and when reliance on gestures is reduced or eliminated.
Gesturing Gives Children New Ideas About Math
The findings suggest that body movements are involved not only in processing old ideas, but also in creating new ones, and that the authors may be able to lay foundations for new knowledge simply by telling learners how to move their hands.
