Memory Test
Is screen time ruining your memory?
Three quick tests measure your word recall, digit span, and pattern memory. See how your score stacks up against screen-time research - and what you can do about it.
How it works
Word recall
Memorise 10 words, then pick them from a list
Digit span
Remember increasingly long number sequences
Pattern memory
Memorise and recreate a grid pattern
Takes about 90 seconds. No sign-up needed.
Does screen time actually affect your memory?
Multiple peer-reviewed studies have found that heavy smartphone use is associated with reduced working memory capacity. A 2023 study published in Nature linked four or more hours of daily screen time to measurable declines in short-term recall. The mechanism involves constant context-switching, which prevents the brain from consolidating new information into memory.
What is working memory and why does it matter?
Working memory is your brain's ability to hold and manipulate information over short periods - like remembering a phone number while you dial it, or keeping track of instructions. It underpins reading comprehension, problem-solving, and learning. When working memory is impaired, everyday tasks feel harder and information slips away faster.
Can you reverse memory effects from screen time?
The cognitive effects of excessive screen time are largely reversible. Research shows that reducing phone use, increasing sustained reading, improving sleep quality, and practicing focused attention can measurably improve working memory within weeks. The brain is highly plastic - it adapts to whatever demands you place on it.
How this memory test works
The test includes three standard cognitive assessments: word recall (memorise and identify 10 words), digit span (remember increasingly long number sequences), and pattern memory (memorise and recreate a visual grid pattern). Your scores are combined into an overall memory rating and contextualised against screen-time research.
