Why a room can make learning harder
Cognitive load theory divides mental effort into three types: intrinsic load (the difficulty of the material itself), extraneous load (unnecessary effort caused by how information is presented or the surroundings), and germane load (effort that helps build understanding). The theory's core guideline is that extraneous load should be reduced so that working memory is free for actual learning [3]. A physical learning environment—such as a noisy room, poor lighting, or distracting displays—can act as a source of extraneous load because students must expend mental effort to filter out or cope with those conditions instead of focusing on the lesson.
In online learning, for example, the physical separation between learner and classroom can create extraneous load that hinders learning, and poor instruction can worsen it [2]. While that study focused on e-learning, the underlying principle applies to any setting: when the environment forces students to manage irrelevant information, their capacity for learning is reduced.
Sometimes extra load comes with a benefit
Not all extraneous load is purely negative. Research on digital and online learning has found that design factors such as interactive media, immersion, disfluency, realism, and redundant elements can induce task-irrelevant cognitive load while still promoting motivation and learning [3]. This means a physically rich or stimulating environment might add load but also engage students in ways that support deeper learning. The key is whether the added load is balanced with the learning goal—what researchers call constructive alignment—so that the overall effect is positive [3].
This nuance matters for the physical environment: a classroom with interesting displays or flexible seating might increase extraneous load, but if those features also increase attention or motivation, the net effect on learning could be neutral or even beneficial. The evidence does not yet specify which physical features fall into which category, but it warns against assuming that all added load is harmful.
When load becomes a barrier to persistence
Extraneous load can also affect students' psychological response to difficulty. In a study of Grade 10 mathematics students, extraneous cognitive load was the strongest predictor of learned helplessness—a sense of giving up when faced with challenges—while germane load was negatively associated with helplessness [5]. This suggests that when the learning environment or instructional design imposes unnecessary mental demands, students may become more likely to feel helpless and disengage.
The same study found that intrinsic load also positively predicted helplessness, but extraneous load had a larger effect [5]. This reinforces that reducing unnecessary load from the environment is important not just for comprehension but for students' confidence and persistence. However, the study was correlational and focused on mathematics instruction, so it does not directly measure physical classroom features; it does show that extraneous load from instructional conditions can have a meaningful psychological cost.
What this means for judging a learning space
For a curious reader, the practical takeaway is to look for sources of extraneous load that clearly compete with the task—such as background noise, visual clutter, or uncomfortable seating—and reduce them when possible. At the same time, recognize that some environmental features that add load may also support motivation or engagement, so the goal is not a sterile room but a space aligned with what you are trying to learn [3]. The evidence also suggests that scaffolding—step-by-step guidance and gradually reduced support—can lower extraneous load even in complex lessons, which means the environment's effect can be moderated by how instruction is designed [1].
What remains less clear is exactly which physical features of a classroom or study space add extraneous load and how large their effect on learning is compared to other factors. The studies here focus on instructional design, digital environments, and psychological responses rather than direct measurements of physical surroundings, so the answer to the question is a qualified yes: the physical environment can add extraneous load and reduce learning, but the size and direction of the effect depend on whether that load is managed and whether it brings motivational benefits.
