Evaluation of related linguistic and cognitive skills

The assessment of linguistic and cognitive skills related to dyslexia plays a fundamental role in the early identification and design of effective interventions.

This session will explore the key dimensions of assessment, from phonological awareness to working memory, highlighting the importance of a holistic approach. Specific instruments, ethical challenges and the connection between these assessments and the design of personalized educational strategies will be addressed.

Assessment of Phonological Awareness

Phonological awareness, the ability to identify and manipulate the sounds of speech, is a cornerstone in the assessment of dyslexia. The ability to distinguish and manipulate phonemes is closely related to the development of reading and writing skills.

Tools such as the Test of Phonological Awareness (CTOPP) and the Test of Phonological Awareness and Speed of Naming (CTOPP-2) assess the individual's ability to segment, merge and manipulate the sounds of language, providing a detailed view of phonological skills.

Verbal Working Memory Assessment

Verbal working memory, the ability to retain and manipulate auditory information in the short term, is involved in fundamental reading processes such as decoding and comprehension. Assessing this skill is essential to understanding the possible difficulties associated with dyslexia. Tests such as the Verbal Working Memory Test (VWMT) explore the individual's ability to remember sequences of verbal information. These instruments make it possible to identify possible deficits in working memory, which can affect reading fluency and comprehension.

Language Development Assessment

Assessing language development is crucial, as language difficulties are closely linked to dyslexia. Problems with oral expression, language comprehension and vocabulary can be early indicators of possible challenges in reading acquisition. Tests such as the Language Development Test (LDT) assess various dimensions of language, including grammar, vocabulary and comprehension. These instruments provide a comprehensive understanding of language skills and their relationship to dyslexia.

Assessment of Reading Speed and Accuracy

Reading speed and accuracy are key aspects of the assessment, as they have a direct impact on reading comprehension. Difficulties in rapid decoding and fluency can be indicators of dyslexia, and their assessment is essential for an accurate diagnosis. The Test of Reading Speed and Accuracy (TRSA) measures the individual's ability to read quickly and accurately. These instruments provide information on processing speed and reading fluency, which are critical aspects in the assessment of dyslexia.

Assessment of Writing and Spelling

Assessing writing and spelling is essential to obtain a complete picture of an individual's language skills. Difficulties in spelling can be indicators of dyslexia, and the evaluation of these aspects contributes to a more precise diagnosis. Tools such as the Spelling and Writing Test (TOR) analyze the individual's ability to express themselves in writing and spelling accuracy. These instruments complement the evaluation of reading and comprehension, providing a complete picture of linguistic skills.

Neuropsychological Evaluation and Brain Neuroimaging

Neuropsychological evaluation examines specific cognitive functions and their possible implications for dyslexia. Tests of memory, attention and executive functions provide information about the individual's cognitive profile. Functional magnetic resonance imaging (fMRI) and positron emission tomography (PET) offer images of the brain in action, allowing the neurobiological basis of dyslexia to be explored. Although they are not routinely used for individual diagnosis, they contribute to the understanding of the underlying neurobiology. Psychosocial and Emotional Assessment Dyslexia can have a significant impact on psychosocial well-being. The assessment of emotional, social and self-concept aspects provides a comprehensive view of how linguistic and cognitive difficulties affect the individual's daily life.

Tools such as the Psychosocial Adaptation Questionnaire (PAQ) explore the individual's self-esteem, anxiety and social interactions. Behavioral observation is also crucial to understanding the real impact of dyslexia in different environments.

Ethical Challenges and Cultural Considerations in Assessment

The assessment of linguistic and cognitive skills faces ethical challenges, including the privacy of the individual and the communication of sensitive results. Ensuring confidentiality and empathy in the process is essential for ethical assessment. Cultural diversity can influence the interpretation of results. The instruments must be culturally adapted, and evaluators must be sensitive to cultural differences in the expression and perception of linguistic and cognitive abilities.

Integration of Results and Design of Personalized Educational Strategies

The return of results must be done in a comprehensive manner, highlighting the strengths of the individual and providing specific recommendations. Parents, teachers and the individual themselves should participate in understanding the findings and planning interventions. The assessment lays the foundation for the design of personalized educational strategies. Intervention plans should address individual needs, capitalizing on strengths and offering specific support in areas of difficulty. Technologies such as artificial intelligence and online assessment applications offer innovative tools. These methods can be more accessible, adaptable and provide real-time data.

Dynamic assessment, which looks at how the individual learns and solves problems, is gaining relevance. This interactive approach can reveal not only difficulties but also effective learning strategies.
