My overconfident understanding is that "regular people" notice a "regular" amount, but let themselves forget about or ignore a "regular" amount of what they found. People with Autism are less able to let go of what they find, and often struggle with over-stimulation from it. People with ADHD start at an under-stimulated baseline, are instinctively looking for too much, and often overcompensate; which leads to a similar over-stimulation.
