We are back for #DyslexiaAwarenessMonth 2020 after all the wonderful feedback we received last year! Every Day we will bust another #dyslexia and #reading myth during the month of October:
MYTH #1 for 2020:
DYSLEXIA AND READING IMPAIRMENTS ARE RARE
While the exact prevalence of #dyslexia/#reading impairments depends on many factors (e.g., the definition, the spoken and written language, diagnostic practices), we can say with great certainty that dyslexia/reading impairments are not rare.
Let's take a look at the numbers: The National Assessment of Educational Progress shows in their report that approx. 65% of 4th graders are not #reading proficiently and the numbers are similar for students in 8th grade. You can find the 2019 report here
nationsreportcard.gov/reading?grade=4
We know that dyslexia estimates range from approx. 3-12% but vary across countries. Prevalence rates for #dyslexia are difficult to estimate due to differences in definitions used, how & at what ages individuals are identified, criteria for diagnosis, & orthographic transparency
Estimates in English-speaking countries range between 5-10%, with greater variance in the US than UK. Estimates are as high as 5-10% in some Asian societies & about 7% in Japan when examining reading w Kanji. Prevalence estimates are approx. 5% in Germany, 3-4% in Italy/Spain.
Most importantly, all struggling readers benefit from early identification & evidence-based interventions regardless of where they live & what caused their difficulties. Learning to read is a basic right, lets all make sure we maximize the joy of learning to read for everyone!

Here is Myth #2 for #DyslexiaAwarnessMonth 2020:
FIRST SIGNS OF #DYSLEXIA OR #READING IMPAIRMENTS CAN ONLY BE SEEN AFTER 2-3 YEARS OF READING INSTRUCTION. Nope. Early signs can be seen as early as preschool. Here is what to look for:
Numerous studies have shown that these skills are predictive of successful #reading acquisition as early as age 4 or 5:
Phonological awareness
Pseudoword repetition
Rapid Automatized Naming
Expressive/Receptive vocabulary
Letter (sound) knowledge
Oral listening comprehension
4 follow-up readings pl look at our review paper w @olaozpa bit.ly/34jtNLd & the wonderful work of many global researchers eg @CattsHugh @yaacovp @lervag M Snowling, C Hulme, @schotz @tiffanyphogan @deevybee @TheDrPT J Malatesha, H Lyytinen, G. Schulte-Körne, & many more

Meet all the #2020 #NEInno #Finalist businesswire.com/news/home/2020…
Thank you @BostonChildrensfor all your support during the development of this! We could not have done this without your Innovation and Digital Health Accelerator!!! #grateful
Thank you @ne_inno for believing in us! #NEInnovation #NEInno

Interested in doing/analyzing #neuroimaging studies in #infants or young #children? New pre-print by @GaabLab led by the wonderful @TedTuresky:
#Neuroimaging the rapidly developing #brain: Current challenges for #MRI studies in the first five years of life
osf.io/7q4cm/
Rapid and widespread changes in #brain anatomy and physiology in the first five years of life present substantial challenges for developmental #MRI studies. One persistent challenge is that methods best suited to earlier developmental stages are suboptimal for later stages
This new review describes the data acquisition, processing, & analysis challenges that introduce these potential biases when conducting & analyzing data from infants and young children & attempts to elucidate decisions & recommendations that can optimize developmental comparisons

Many school districts are deciding to use 'survey' or 'questionnaire' #screeners (asking teachers a series of questions) for assessing #dyslexia risk instead of directly assessing the child. It's very problematic for various reasons & can harm our #dyslexia advocacy efforts1/6
1) Several research studies have shown that teacher surveys are poorly correlated with the actual performance of a child, especially at the beginning of K (or any grade since teachers are still getting to know the student). It' important to DIRECTLY assess the child's skills 2/6
For example, this study bit.ly/36Gve6e: shows "..teachers’ judgments of students’ early #literacy skills alone may be insufficient to accurately identify students at risk for #reading difficulties. So, why are we still using these? 3/6
