Researchers at Florida Atlantic University and Brown University found that participants learned visual categories based on integrated patterns more accurately when they used larger arm movements than when they pressed a button. The advantage did not appear for categories learned through explicit rules and persisted when participants later switched to button presses.
Researchers from Florida Atlantic University and Brown University found that people learned some visual patterns more effectively when they responded with larger arm movements rather than simple button presses. In a virtual reality experiment reported in Science Advances, movement improved learning of categories that required participants to combine features and recognize similarities, but did not meaningfully help when categories could be learned using explicit rules.
The research team tested participants in an immersive virtual reality task. Participants categorized visual patterns either by pressing a button or by making a larger movement: swinging a virtual lightsaber at a target or punching a virtual response box. The response-box task did not involve direct contact with the visual pattern, allowing the researchers to test whether movement itself mattered, rather than an action physically matching the stimulus.
The researchers examined two forms of category learning. In rule-based learning, a person can use stated features or rules to decide which category an item belongs to. In similarity-based learning, a person must integrate several features and recognize a pattern, sometimes without being able to explain the judgment in a simple rule. Participants who made larger movements learned the similarity-based categories more accurately than those using button presses. The movements did not produce a meaningful advantage on the rule-based task, including when researchers made that task more difficult.
The team also tested whether viewing time or response speed could account for the result and modified the rule-based task to increase its complexity. According to the report, the selective advantage for larger movements remained. Participants who first learned with larger movements also retained an advantage after switching to button presses, a result the researchers say points to an effect on learning rather than only on immediate response performance.
Movement May Help Pattern-Based Training
The findings suggest that how a person responds during training may influence learning itself, at least for tasks that depend on combining multiple pieces of information. Many practical judgments, such as interpreting medical images or recognizing patterns in aviation settings, involve more than applying a single explicit rule. The study raises the possibility that training for such tasks could benefit from purposeful physical action rather than relying exclusively on seated, button-based exercises.
That possibility is not yet a recommendation for changing professional training. The experiment tested a controlled visual categorization task, not clinical diagnosis, flight performance or other real-world outcomes. Still, the reported carryover after participants switched response methods gives researchers a reason to investigate whether movement can support learning beyond the moment of action. If replicated in applied settings, the approach could inform the design of virtual reality training and other exercises built around complex pattern recognition.

Testing Action During Categorization
Category learning is often studied as a process in which people identify what they are seeing and then make a response. In that approach, movement is treated mainly as the way a decision is communicated. The Florida Atlantic and Brown team instead tested whether the physical response made while learning could affect how well categories were acquired.
Lead researcher Luke Rosedahl, an assistant professor of biomedical engineering at Florida Atlantic, said the result was selective: larger movements aided learning when participants had to integrate features, but offered no meaningful benefit for explicit-rule learning. He also noted that the effect appeared whether participants swung at a target or punched a separate response box. The study therefore points to movement as a possible contributor to learning, while leaving open which aspects of movement produce the benefit.
The researchers’ stated interest includes difficult training tasks where conventional instruction may not be enough. The report says Rosedahl’s earlier research found that written instructions explaining how to perform a task did not improve performance. The new experiment does not establish that movement will solve those training challenges, but it tests a different way to structure practice.
“Larger movements substantially improved learning when people had to recognize patterns by integrating multiple features, but provided no meaningful benefit when people learned categories using explicit rules.”

Real-World Effects Remain Untested
The reported findings come from a virtual reality categorization experiment. The available report does not specify the participant count, the size of the accuracy difference, or how long the retained advantage lasted. It also does not establish whether similar benefits occur in real-world settings, in other age groups, or during training for specific professions.
The study identifies a difference between larger movements and button presses for one category-learning task, but it does not determine why the effect occurs. The researchers say further work is needed to test whether the result carries over beyond the experiment. It is also unclear which kinds, duration or intensity of movement would be useful in practical training.
Researchers Must Test Applied Training
The next step identified in the report is to determine whether the learning benefit extends to real-world settings. Further studies could test purposeful movement in training tasks that require people to combine information and recognize patterns, including medical or aviation-related exercises. Those tests would need to establish whether improved performance in a laboratory-style categorization task translates into durable skills and better results in practical settings.
For now, the study supports a narrower conclusion: larger movements helped participants learn similarity-based visual categories in the tested virtual reality task, while explicit-rule learning did not show a meaningful benefit. Until follow-up research tests applied training, movement-based methods should be treated as a research direction rather than a proven replacement for existing instruction.
Key Questions
What did the study find?
Participants using larger arm movements learned visual categories requiring them to integrate features more accurately than participants using button presses. The study found no meaningful movement advantage for categories learned through explicit rules.
Did movement help every kind of learning tested?
No. The reported benefit was specific to similarity-based category learning. Researchers found no meaningful improvement for the rule-based task, even after making it more challenging.
Did the effect depend on touching the visual target?
The report says the advantage occurred both when participants swung at a virtual target and when they punched a separate response box. That suggests direct interaction with the visual stimulus was not required in the experiment.
Does this prove movement improves medical or aviation training?
No. The researchers said movement could inform training for complex tasks, but the reported experiment tested visual categories in virtual reality. Whether the benefit carries over to professional or real-world training remains unclear.
