Dyslexia, in short, involves difficulties in the surface structure of language, in encoding and decoding language.
More scientifically, dyslexia manifests in two key areas:
1. Writing/Encoding Language:
Encoding is the process of ‘writing’ using symbols or letters, such as representing what I hear, what I’m copying, or what I am trying to express in my own words. This area involves difficulties with the ability to convert thoughts into written language, which includes spelling, grammar, and organizing ideas coherently on paper.
2. Reading/Decoding Language:
Decoding, is the ‘reading’ of what is written with the symbols of language. This area involves difficulties with the ability to interpret written language, including recognizing words, understanding their meaning, and reading fluently.
Each child’s experience with dyslexia is unique, necessitating individualized strategies, taking into consideration the specific cognitive profile of the child and designing tailored interventions to support not only his learning, but also his emotional development.
According to the Diagnostic and Statistical Manual (DSM, 2013), Dyslexia is used as ‘an alternative term to refer to a pattern of learning difficulties characterised by problems with accurate or fluent word recognition, and poor decoding and poor spelling abilities.”
Dyslexia in Reading affects three axes:
• Accuracy in reading words,
• Fluency, expression, and speed in reading,
• Reading comprehension.
Dyslexia with Impairment in Written Expression affects three axes:
• Spelling,
• Grammar and punctuation,
• Written expression.
Given these factors, a proper learning evaluation must identify the specific areas where dyslexic characteristics are present in each individual case.
