Why Does a Clicking Pen Drive Some People Mad?

Exam season is under way in many UAE schools. Picture the room: forty desks, one clock, total silence. Then a pen starts clicking. For the student holding it, that click is doing a job. For the student two rows back, it can land like an alarm.

Both reactions are real, and neither is about manners. Here is what the science says about each side, and how to keep the useful part of fidgeting without the sound.

One sound, two very different brains

Some people react to specific everyday sounds with a surge of irritation, anxiety or anger that feels out of proportion. Researchers call this misophonia. The trigger is usually a sound another person makes: chewing, breathing, tapping, clicking.

It is more common than most people think. In a 2023 survey of 772 UK adults, sampled to match the population by age, sex and ethnicity, 18.4% reported misophonia symptoms that caused them significant burden (Vitoratou et al., 2023). Only 13.6% had ever heard the word. One caveat: this was a questionnaire cut-off, not a clinical diagnosis, and it covered adults only.

What happens in the body

In a small laboratory study, adults with misophonia showed larger skin conductance responses to trigger sounds than a matched control group (Edelstein et al., 2013). Skin conductance tracks the sympathetic nervous system, the branch that prepares the body for fight or flight. In interviews from the same study, pen clicking was named among the problem sounds. Only six people with misophonia took the lab test, so treat it as a starting point.

Why the person clicking rarely notices

The same interviews revealed something useful for families: 10 of the 11 participants said their own trigger sounds did not bother them. The sound that is unbearable from a neighbour can be invisible when you make it yourself. That helps explain why the clicker is usually the last to know.

Why children hear the room differently

Children are still building the skill of tuning sounds out. A review of noise and learning research concluded that children are less able than adults to ignore irrelevant sounds (Klatte et al., 2013). In one study it cites, first-graders' memory performance dropped with non-verbal classroom sounds that did not affect older children or adults. The authors note these effects are usually small, but in a silent exam room, small adds up.

How it shows up in exam week

The clicker is often a sensory seeker. Movement and touch help them hold attention, a pattern we looked at in why some fidgets help focus and others get in the way. When the stakes rise, the hands look for something to do.

The neighbour may tense up, lose their place in a question, or feel a flash of irritation they cannot explain. Some people with misophonia even copy the sound back, a coping strategy several participants described in the Edelstein interviews.

None of this is limited to children. Teens revising in a library and adults in an open-plan office meet the same clash every day.

What helps: keep the input, lose the sound

The goal is simple. The fidgeter keeps the input their nervous system is asking for. The room keeps its quiet.

Swap clicking for squeezing

A silent squeeze ball gives the hand resistance and pressure with no sound at all, and it works one-handed, without looking.

Give the pen-chewer a better option

Many students chew or bite pens while they think. A chewable silicone pen topper gives the same oral input on the pen they are already holding. Silicone has no crunch, and with lips closed it stays quiet.

Check the rules before exam day

Exam rooms often limit what can sit on the desk. Ask the school what is allowed, then practise with the same tool during a timed session at home so it feels familiar on the day.

If your child is the one bothered

Take the reaction seriously rather than asking them to ignore it. Ask whether they can sit further from the source, and whether ear defenders are allowed. If strong reactions to everyday sounds keep disrupting school or family life, raise it with your child's doctor.

Quiet works both ways

Fidgeting is a regulation strategy, and sound sensitivity is a real nervous system response. A quiet tool respects both: one child keeps the input that helps them focus, and the child beside them keeps the silence that helps them think.
