tricks, such as reading backwards or reading aloud, to keep your brain from altering the way you process visual information when proofreading.

The answer is Perceptual Tricks.

Proofreading is not just scanning up and down the page. There are techniques that can be used to make proofreading a methodological process that can ensure high-quality output, like using perceptual tricks. Our brain can trick us because it has a skill that can supply missing pieces and can correct mistakes subconsciously, making us miss some errors in our output. To avoid this, we can trick our brain by changing the way we process visual information such as reading backward.
