Measure your visual attention, processing speed, and cognitive flexibility by connecting numbered and lettered circles in sequence.

Takes approximately 3-5 minutes

What is the Trail Making Test?

Tests your ability to scan and locate targets quickly across a visual field, a fundamental skill for reading and navigation.

Part B specifically measures your ability to switch between different categories (numbers and letters), a key executive function.

Connect circles numbered 1 through 25 in order. This measures your basic visual scanning and processing speed.

Alternate between numbers and letters: 1 → A → 2 → B → 3 → C... This adds the challenge of task switching.

Complete each part as quickly as possible while avoiding errors. The difference between Part B and Part A reveals your "switching cost."

Good cognitive flexibility helps you switch between tasks efficiently, essential in today's multi-demand environments.

Visual scanning and attention skills support efficient navigation of complex problems and information.

The TMT is widely used to assess cognitive health and can track changes over time. Regular practice may help maintain these abilities.
