What Is the Schulte Grid? A Complete Guide to Attention Training

What Is the Schulte Grid?

The Schulte Grid (also called Schulte Table) is a classic psychological exercise designed to improve attention, concentration, and peripheral vision. Originally developed by German psychiatrist Walter Schulte for studying attention span, it has become a popular training tool for anyone looking to sharpen their focus.

How Does It Work?

A standard Schulte Grid is a 5×5 table containing numbers 1 to 25 arranged in random order. The task is simple: find and click (or point to) each number in ascending order as quickly as possible.
