Reading on a screen is harder than reading on paper, and the SAT is now on a screen
Across 54 studies and about 171,000 readers, people understand the same text less well on a screen. The gap is widest under the two conditions the SAT Reading section happens to combine, and it has not narrowed as screens became normal.
The assumption everyone makes about the digital SAT is that screens are not a problem for students who grew up with them. The research points the other way, and the two conditions that widen the gap are both present in the Reading and Writing section.
A 2018 review by Pablo Delgado and colleagues pulled together 54 studies covering roughly 171,000 readers and compared how well people understood the same text on paper and on a screen. On average, readers understood the same text less well on a screen. The overall effect was modest rather than dramatic, and it is an average across many studies and text types rather than something that happens to every reader every time. Two details about it matter for this exam.
The two details that matter
The gap widened under time pressure. Across the studies where reading was self-paced, paper held little or no advantage. Where reading was timed, the advantage for paper was clear. The SAT gives you about 71 seconds per question in Reading and Writing.
The gap was about informational text, not stories. Narrative passages showed essentially no screen penalty. Writing that explains or argues showed a clear one. SAT Reading draws on literature as well as science, history, and the humanities, so this applies to a large share of what you will read rather than all of it.
A clock and informational prose, in other words. Both are features of the section you are about to sit.
A third finding undercuts the usual reassurance. Studies published more recently show a larger gap, not a smaller one. That is a pattern across publication years rather than a study that followed the same readers over time, so it is not proof that exposure fails to help. But if growing up with screens closed the gap, the more recent research is where you would expect to see it closing, and it is not.
Why screens make close reading harder
The research does not settle the mechanism, but the most supported explanation is about how people behave on a screen rather than anything about eyes or displays.
Screens are where you skim. Years of reading feeds, messages, and articles have trained a scanning habit: move fast, get the gist, keep going. That is efficient for most of what anyone reads on a phone and actively wrong for a passage where the answer depends on one qualifying word.
Readers also judge their own understanding differently on screen. In several studies people felt they had understood a screen text as well as a paper one, then scored lower on it. Feeling finished arrives sooner than being finished. Under time pressure you act on that feeling, move to the answers, and pick the choice that matches the gist rather than the text.
Paper also gives you position. You remember roughly where on a page something sat, and you can keep a finger on it. Screens weaken that, which matters more for long texts than for the SAT, where a Reading and Writing passage is usually only a few sentences. The habit it leaves behind is the part that carries over: not going back to look, because looking feels like it costs time.
How to practise for a screen
Unless you have an approved accommodation for a paper version, you are testing on a screen. What you can change is how you practise.
Practise on the same screen you will test on. If you do most of your reading practice on paper, you are training in the condition where you are already stronger and testing in the one where you are weaker. Do timed reading on a screen, deliberately.
Make the passage physically active. Mark the sentence you are relying on before you look at the choices. On the real exam you can highlight. The point is not the mark, it is that selecting a specific sentence forces you to locate evidence rather than answer from an impression. If you find you cannot pick a sentence, you do not have the answer yet.
Answer from the text, not from memory of the text. After you read a passage you have a summary in your head. The wrong choices on SAT Reading are frequently written to match that summary while contradicting a specific line. Go back and look. Of everything here, this is the habit I would build first.
Slow down at the qualifiers. Words like most, some, only, rarely, and unlike carry the answer more often than the nouns do, and they are what skimming drops first.
Do not trust the feeling of being done. If a passage felt easy and quick, that is the exact condition the research describes. Spend the extra ten seconds checking one choice against one line.
A habit, not a limitation
None of this means you are worse at reading than students who took the paper test. It means the format asks for a mode of reading that screens have trained most people out of, and that this is a habit rather than a limitation. Habits respond to practice in the right conditions.
It also means the most common piece of reassurance you will hear about the digital SAT, that your generation is fine with screens, is not supported. Comfort with screens is real. Careful reading on screens under a clock is a separate skill, and it is the one being tested.
