Letter addition/subtraction - People with dyslexia may perceive a word with letters added, subtracted, or repeated. This can lead to confusion between two words containing most of the same letters. Highly phoneticized spelling - People with dyslexia also commonly spell words inconsistently, but in a highly phonetic form, such as writing "shud ...

Reading is an area that has been extensively studied via the computational model system. The dual-route cascaded model (DRC) was developed to understand the dual-route to reading in humans. [14] Some commonalities between human reading and the DRC model are: [5] Frequently occurring words are read aloud faster than non-frequently occurring words.
Parallel letter recognition is the most widely accepted model of word recognition by psychologists today. [3] In this model, all letters within a group are perceived simultaneously for word recognition. In contrast, the serial recognition model proposes that letters are recognized individually, one by one, before being integrated for word ...
These people typically adapt to their disability and are able to use a style of compensatory reading known as letter-by-letter reading. [15] This style of reading takes longer than the conventional style of reading does. As the number of letters in a word increases, the amount of time it takes for the person with pure alexia increases.
Rapid automatized naming (RAN) is a task that measures how quickly individuals can name aloud objects, pictures, colors, or symbols (letters or digits). Variations in rapid automatized naming time in children provide a strong predictor of their later ability to read, and is independent from other predictors such as phonological awareness, verbal IQ, and existing reading skills.

The National Institute of Neurological Disorders and Stroke defines reading disability or dyslexia as follows: "Dyslexia is a brain-based type of learning disability that specifically impairs a person's ability to read.
Reading by using phonics is often referred to as decoding words, sounding-out words or using print-to-sound relationships.Since phonics focuses on the sounds and letters within words (i.e. sublexical), [13] it is often contrasted with whole language (a word-level-up philosophy for teaching reading) and a compromise approach called balanced literacy (the attempt to combine whole language and ...
