1.​ This effect shows that prior knowledge of words influences early stages of visual
perception, allowing the brain to use context to improve letter recognition.
2.​ The data show the word superiority effect because accuracy was higher when letters were
presented as part of real words compared to when they were presented in nonwords or
alone. This pattern suggests that similar word structure helped guide perception, making
it easier to correctly identify letters even under brief or challenging viewing conditions.
3.​ The word superiority effect can seem counterintuitive because it might be expected that
identifying a single letter would be easier when it appears alone, but without any
surrounding visual information. Instead, the effect shows that additional letters actually
help perception rather than interfere with it. This indicates that the brain processes words
as meaningful whole rather than as a series of isolated letters.
