Visual and Auditory Sequential Memory

Sequential memory requires items to be recalled in a specific order. In saying the days of the week, months of the year, a telephone number, the alphabet, and in counting, the order of the elements is of paramount importance.

Many dyslexics have poor visual sequential memory, i.e. a poor ability to perceive things in sequence and then remember the sequence. Naturally this will affect their ability to read and spell correctly. After all, every word consists of letters in a specific sequence. In order to read one has to perceive the letters in sequence, and also remember what word is represented by that sequence of letters. By simply changing the sequence of the letters in name, it can become mean or amen. Some also have poor auditory sequential memory, and therefore may be unable to repeat longer words orally without getting the syllables in the wrong order, for example words like preliminary and statistical.
