"It's Like Drinking from a Fire Hose": Understanding and Characterizing Video Learning Experiences for Individuals with ADHD
This paper investigates the specific challenges individuals with ADHD face when watching video lectures by combining eye-tracking data with retrospective think-aloud reflections from 16 participants to identify hindering design elements, characterize behavioral patterns, and derive design implications for future adaptive learning systems.

Learning from video has become a standard part of modern education and professional training, offering flexibility that textbooks cannot match. For many, the ability to pause, rewind, or watch at a different speed transforms how they absorb information. However, for people with Attention Deficit Hyperactivity Disorder, or ADHD, this same medium can present a unique set of hurdles. ADHD is a condition that affects how the brain manages attention and impulses, often making it difficult to sustain focus on tasks that are not immediately stimulating or to filter out distractions when the environment is too busy. While general theories of learning suggest that combining pictures and words helps everyone understand better, these same combinations can sometimes overwhelm a brain that struggles to process multiple streams of information at once. The question researchers have long faced is how to design educational videos that work for everyone, including those whose brains process the world differently.
To answer this, a team of researchers at the University of Wisconsin-Madison conducted a detailed study with sixteen adults who have ADHD. They wanted to understand exactly what happens inside the mind of a viewer when a video lecture becomes difficult to follow. Instead of just asking people what they thought after the fact, the researchers set up a special viewing room where participants watched two different video lectures while their eye movements were tracked by a sensitive camera. This technology allowed the scientists to see exactly where a person was looking, how long they stared at a specific spot, and when their eyes wandered away from the screen. After watching, the participants spoke aloud about their experience while the researchers played back the video, showing them their own eye movements on the screen. This method helped the participants remember exactly what they were feeling and thinking at specific moments, turning vague memories into concrete data about how their attention shifted.
The study revealed that the biggest barrier to learning was not a lack of interest, but rather a mismatch between the video's design and the viewer's ability to process it. One major issue was cognitive overload, which happens when a video presents too much information at once. The researchers found that when slides were packed with dense text or complex charts, viewers with ADHD often felt like they were being hit with a flood of data they could not catch. One participant described the sensation vividly, comparing it to drinking from a fire hose. In these moments, the eye-tracking data showed that viewers would either skip over most of the text, reading only a few words before giving up, or they would stare blankly at the screen, their eyes moving across the lines without actually understanding the words. They were physically looking at the content, but their minds had checked out.
Another significant challenge was the opposite problem: understimulation. When a video was too slow, monotone, or visually static, viewers with ADHD would lose their focus entirely. The eye-tracking cameras captured this clearly, showing long periods where a person would stare at a single point on the screen for several seconds without moving their eyes. This was not a sign of deep concentration, but rather a state of boredom where the brain had stopped engaging with the material. To cope with this, many participants developed their own strategies. Some would speed up the video to make the speech feel more energetic, while others would look at secondary details, like the captions or the background, just to give their brains a small jolt of stimulation to help them stay awake. Some even admitted to intentionally letting their minds wander during boring parts, trusting that they could snap back to attention when the speaker said something important.
The researchers also discovered that abrupt changes in a video could break a viewer's train of thought. If a video switched suddenly from showing a speaker to showing a slide, or if the speaker jumped to a new topic without warning, viewers with ADHD often struggled to remember what they had just seen. Their eyes would scatter across the screen as they tried to figure out where they were in the lesson. To fix this, many participants relied on the ability to pause and rewind, but this strategy had a cost. It turned a smooth learning experience into a stop-and-start process that required extra mental effort to restart their focus every time they hit play again.
Beyond the video itself, the study found that people with ADHD often turned to outside tools to make sense of what they had watched. Several participants used artificial intelligence to rewrite confusing notes or to check if they had understood the main points correctly. However, this came with its own set of worries. They were concerned that an AI might summarize the video in a way that missed the teacher's true intent or got the facts wrong. Because their brains often struggle with tedious tasks, they found it hard to spend the extra time needed to double-check the AI's work, leaving them in a difficult position where they needed help but were afraid to trust it completely.
The findings suggest that making video learning accessible for people with ADHD requires more than just adding captions or slowing down the speech. It demands a design that balances stimulation without causing overload. The researchers propose that future video systems should be able to notice when a viewer is struggling—perhaps by seeing that their eyes have stopped moving or are wandering—and then gently adjust the presentation to help them refocus. This could mean highlighting key points when a topic changes or offering a simpler view of the content when the screen becomes too crowded. The ultimate goal is to create a learning environment where the technology adapts to the person, rather than forcing the person to adapt to the technology, ensuring that the wealth of knowledge available in video lectures is truly accessible to everyone.
