The perception test checks your ability to perceive, store, and compare visual information in a short period of time. The test shows a series of multicolored object arrangements. Your task is to identify the differences (changes) in the second image.

Train at four different difficulty levels and learn step by step. The difficulty varies in the following parameters:

• Number of objects
• Seconds
• Number of changes
• Complexity of the arrangements

For supported learning, you can (optionally) activate the solutions directly while training.

We’ve also enhanced the test with a mode: You can either select statements (e.g. how many items changed), directly select the objects that have been modified, or mix both modes.

This test also supports our testing philosophy: The tasks are generated dynamically to create a lasting learning effect.
