Flanker test: train selective attention and focus

The Eriksen Flanker Test trains selective attention and distractor resistance. Learn how this exercise can improve your focus.

SynapseGym Team

The Eriksen Flanker Test was developed in 1974. It measures the ability to ignore irrelevant information. You are shown a row of arrows — you must only respond to the middle one and ignore the surrounding 'Flankers'. In incongruent trials (Flankers point in a different direction) you are slower.

The Flanker Effect:

Congruent (easy)

→ → → → →

All point to the right

Incongruent (difficult)

← ←← ←

The middle point is different.

Task: Only respond to the MIDDLE arrow!

Scientific significance

The Flanker test measures selective attention, conflict processing, and cognitive control. Over 5,000 scientific studies use it. fMRI studies show activation in the anterior cingulate cortex. The Flanker interference can be reduced through training.

Application in daily life

In the office: finding important information despite distractions, in meetings follow the speaker, in open office work. In road traffic: recognizing the relevant sign among advertisements, paying attention to the correct road user. While learning: distinguishing key points from details, not letting yourself be misled by incorrect answer options.

Improvement strategies

Narrow your focus: consciously concentrate only on the center. Anticipation: expect conflicts will occur. Speed vs. accuracy: prioritize accuracy at first, later increase speed. After 2-3 weeks of training, measurable improvements are typical.

Only look at the center

Anticipation

Expect conflicts

Balance

Accuracy before speed
