Un análisis documental de la investigación en dislexia en la edad adulta

Abstract

Dyslexia in adulthood affects around 4% of the population. Thus, this study offers an overview of the methodological aspects and the areas of research in dyslexia in adulthood. From a bibliographical search conducted in the Psychological Abstracts database: PsycINFO, we identified and selected the studies the review was to focus on. Results show in relation to methodological aspects, quantitative research methods are preferred in 59.4% of cases, whereas 5.7% opted for qualitative methods. Also, in 10% of the studies, used N=1 designs and in an under 10% studies used surveys, longitudinal/ follow-up studies or neurobiological procedures. In relation to the topics of research, 40.6% analyzed cognitive processes (phonemic awareness, memory, IQ, naming speed) and/or academic achievement (word reading, pseudoword reading, spelling, and reading comprehension), the 25.4% we re neurobiological studies (neurological and genetics), the 12% were studies focusing on intervention, the 8% focused on identification/ diagnostic, and 5.4% analyzed associated problems to dyslexia in adulthood. The primary objectives of the research appear to be the characterisation of dyslexia and studies about neurobiological basis of dyslexia in adulthood. Research is also extended towards other, more practical matters.
