Attention is the gatekeeper of thinking. If it doesn’t filter the right information in, memory and reasoning never even get a chance to work.
Tasks like the Stroop test and Flanker task show how your attention system handles conflict and distraction.
1. Two systems of attention
We can roughly separate two mechanisms:
- Bottom-up attention: pulled automatically by sudden or intense events (notifications, sounds, flashes).
- Top-down attention: guided by your goals and intentions.
Focus means keeping top-down control strong enough to resist bottom-up distractions.
2. What interference tasks reveal
In the Stroop task, reading the word interferes with naming the ink colour. In the Flanker task, side arrows push you toward the wrong answer.
These mimic real life: phones lighting up, side conversations, busy open-office environments, or internal thoughts interrupting a task.
3. Why notifications are so powerful
Apps are optimised to hijack bottom-up attention: sound + colour + social meaning = “something needs you”.
Even a quick glance breaks mental continuity. You return to the task, but the mental context reloads, costing more time than you feel.
4. Mental noise & stress
Even without external triggers, internal noise (worries, plans, self-talk) drains attention. Under stress, this noise gets louder, leaving less capacity for focused tasks.
5. Building an attention-friendly environment
- Silence non-critical notifications during focus time
- Keep only needed tabs and documents open
- Use headphones or quiet spaces
- Set up “do not disturb” agreements if possible
6. Training focus wisely
Don’t force marathon concentration. Use short, structured focus intervals:
- 15–30 minutes of single-task work
- 3–5 minute breaks
- Repeat a few cycles
Occasionally check tasks like Stroop or Flanker to see how your attention behaves under different life conditions.
