Selective adaptation is when we view a stimulus with a specific property, and the neurons tune to that property fire, eventually becoming fatigued.

Neurons tune to a particular attribute fire when we see a stimulus with that property; over time, this firing fatigues the neurons or causes them to adapt. The neuron's firing rate drops due to this adaptation and fires less often when the same stimulus is provided to it again right away.

For instance, a page of plain black text on a white backdrop will undoubtedly capture your attention and make it easier for you to identify important information. However, if you keep viewing pages and pages of mainly neon pink highlights, you'll probably grow accustomed to them, and they will eventually stop drawing your attention.
