Why does reading comprehension decline for text displayed on low-contrast signage in a dense urban environment with varying ambient light?

💡 Explanation

Reading comprehension suffers because the low contrast combined with environmental distractions increases demands on bottom-up processing, requiring excessive cognitive resources for basic character recognition. Therefore, higher-level comprehension suffers, rather than being impacted primarily by semantic priming or phonological loop issues, which would have distinct cognitive signatures.
