The Science Behind Highlighting: Are You Doing It Correctly?


Highlighting is one of the most common study and workplace habits. From learners preparing for exams to professionals reviewing reports, adding colour to a page feels productive.

But here’s the real question: Is highlighting actually helping you remember information — or just making your notes look organised?

Let’s explore the science.

Does Highlighting Improve Memory?

Research in educational psychology shows that highlighting can improve learning — but only when used strategically.

For reliable, brilliant results, the Schneider Assorted Highlighter Pouch (4’s) is designed with a large ink reservoir capable of highlighting more than 15 000 words — making it a smart choice for learners and professionals alike.

Because smart highlighting leads to smarter studying — and smarter working.
