When was the last time you read someething longer than a few pages without checking your phone?

From TikTok to Instagram Reels, today, our digital lives are built around speed. Content is short, auto-played, and algorithmically personalised.

There is always something new waiting. It’s convenient, of course, but it may also be reshaping how we tolerate boredom, effort and delay.

Many platforms rely on what psychologists call “variable reinforcement schedules.”

Rewards for your dopamine receptors, which can take the form of new likes, messages, comments or content updates arriving unpredictably, triggering dopamine pathways associated with anticipation and motivation.

The uncertainty of when these “rewards” will arrive is what keeps us scrolling. It’s the same behavioural principle used in slot machines. We are not powerless, but we are being nudged.

Over time, this design may condition us to expect constant stimulation. University work, by contrast, often demands the opposite: sustained attention, delayed gratification, and the ability to sit with complexity.

Reading a dense theory text cannot compete with an infinite feed of easily consumable visually stimulating content, tailored to our exact interests and engineered to refresh every few seconds.

While many student will brush off a study session broken up by scrolls and messages in the group chat for a quick Red Bar pint as multitasking, research suggests this is actually called “task-switching”.

Each switch carries a cognitive cost. Working memory becomes strained, comprehension dips and mistakes increase.

When studying happens alongside notifications and group chats, the brain is constantly resetting rather than deepening focus.

There are wider cultural signals too. Teachers and lecturers increasingly report students struggling with long-form reading, and literacy organisations have warned of declining reading for pleasure among young people.

While it would be simplistic to blame TikTok alone, educational policy, pandemic disruption and economic stress all matter. This makes it difficult to ignore the shift in how attention is trained.

Crucially, attention is not disappearing. Students can spend hours gaming, editing videos, or deep-diving into niche online communities.

Is the issue, therefore, conditioning over capacity?

If we are becoming so accustomed to rapid rewards and compressed information, it’s no wonder delayed gratification now requires deliberate effort.

This does not mean our brains are irreparably damaged. Neuroplasticity works both ways.

But it does mean we may need to actively reclaim focus rather than assume it will ome naturally.

Maybe the question is no longer whether technology affects attention; we know now it clearly does.

The real question is whether universities and students, themselves, are ready to push back against systems designed to shatter attention spans.
