Learning Disabilities

Dyslexia 

Dyslexia is a neurologically based specific learning difficulty that is characterised by difficulties in one or more of reading, spelling and writing. Accompanying weaknesses may be identified in areas of language acquisition, phonological processing, working memory, and sequencing. Some factors that are associated with, but do not cause, dyslexia are poor motivation, impaired attention and academic frustration.

The extent to which dyslexia is apparent in a particular language is affected by the quantity and quality of exposure to that language and other languages. Dyslexics are likely to have greater difficulty with languages that have more complicated orthographic, phonological and/or grammatical systems.

It has been estimated that 3% to 5% of Singaporeans may be dyslexic. The difficulties caused by dyslexia can be overcome with specialist teaching and the use of compensatory strategies.

Short-term and/or Working Memory
Many dyslexics are 'quick forgetters'. They may learn and understand how to do something but they will need frequent reminders before they remember. It is not uncommon to have to keep repeating something over and over to dyslexics to try and ensure they remember it. For example, they may have excellent long-term memory for movies, experiences, locations and faces, but poor memory for sequences as well as unfamiliar facts and information

Sequencing
A lot of dyslexics have difficulty sorting or ordering information. This means that the dyslexic individual may have difficulty in Mathematics, remembering a list of instructions or giving a good verbal explanation.
