A cognitive illusion can be defined as the viewer's knowledge and assumptions about the world, or unconscious inferences. There are three categories of cognitive illusions: ambiguous illusions, distorting illusions, and paradox, or fiction, illusions. Ambiguous illusions are images or objects that allow for the viewer to have two valid interpretations of what the object represents or what it actually is. The viewer is usually able to mentally visualize one interpretation right away and eventually the second, after some time.
Cognitive deficit or cognitive impairment is an inclusive term to describe any characteristic that acts as a barrier to the cognition process. The term may describe. deficits in overall intelligence (as with intellectual disabilities), specific and restricted deficits in cognitive abilities (such as in learning disorders like dyslexia), neuropsychological deficits (such as in attention, working memory or executive function), or it may describe drug-induced impairment in cognition and memory (such as that seen with alcohol, glucocorticoids, and the benzodiazepines.)
