How does the use of all caps affect those with learning disabilities?

The use of all caps can significantly impact readability for individuals with learning disabilities. All capital letters change the shape of words, creating a uniform appearance that can make it more challenging to differentiate between letters and to recognize whole words quickly. This is particularly problematic for those who rely on visual cues or the unique shapes of lower-case letters to assist them in reading.

For many people, especially those with dyslexia or other learning disabilities, the use of mixed case (upper and lower case) can provide more distinct features that aid in word recognition, speeding up the reading process and enhancing comprehension. Therefore, presenting text entirely in all caps can hinder rather than help readability and understanding.
