“My mind doesn’t work like a train track. It’s more like a web page with lots of hyperlinks.” – dyslexic honors college student. It’s refreshing to see that more researchers take an interest on dyslexia beyond reading. In this recent paper from Belgium and Missouri, the challenges of remembering sequential information for dyslexics and non-dyslexics was reviewed. Both working memory and sequencing were examined. Working memory is a type of short-term memory necessary for keeping information ‘in mind.’ Sequencing is remembering the order that things are said. It’s activities such as this that that can make something like following classroom instructions or remembering computer passwords easy or hard. Several interesting observations were made from their review of the research literature: – Dyslexic children and adults tend […]
Memory: Why Drill Can Kill – and What to Do Instead [Premium]
It would almost seem without question that repetition should be helpful for learning, but researchers have found that if repetitions are too much and too long (longer than 10 seconds in one paradigm), further repetition caused poorer memory and word retrieval rather than better! From one of the papers below: “Both Experiments 1 and 2 demonstrated a striking and clear violation of the memory benefits typically associated with repetition. Specifically, increasing the rehearsal time of a word did not yield a straightforward monotonic increase in performance on a later free association test; rather, it led to a nonmonotonic effect, with performance initially increasing, but then declining with longer repetition durations.” The reason for this effect is currently being studied, but the researchers speculated that the increased forgetting […]
Math and Dyslexia: Dyslexic Advantage Talks to Stanford & Georgetown Experts Tanya Evans and Michael Ullman
Last week, I had a chance to chat with Stanford's Tanya Evans and Georgetown's Michael Ullman about their recent research paper about procedural learning and math. In their paper, their definition of procedural learning relates to the type of learning that...
How Dyslexic MIND Strengths Integrate with Multiple Intelligences [Premium]
In our book, The Dyslexic Advantage, we spoke about the 4 MIND strengths common in adult dyslexics: M for Material Reasoning, I for Interdisciplinary Reasoning, N for Narrative Reasoning, and D from Dynamic Reasoning. These skill clusters and talent sets had parallels in brain systems and processes as well as careers, domains of expertise, and areas of innovation. Multiple Intelligences is a concept that was introduced by Howard Gardner of Harvard to identify specific modalities that went beyond a single intelligence or general ability. The seven he initially characterized were: musical-rhythmic, visual-spatial, verbal-linguistic, logical mathematical, bodily, kinesthetic, interpersonal, and intrapersonal. The ones he considered adding later were naturalistic (able to classify natural forms, ecological ‘receptiveness’), existential or spiritual, and teaching -pedagogical in telligence. Somewhat related […]
Q & A: Can Someone Be Both Dyslexic and Autistic ? [Premium]
QUESTION: Is it Possible to Have Both Dyslexia and Autism? The short answer is yes, but it’s likely not very common and in general many of the features of dyslexia and autism are opposite. By strict criteria, low IQ and autism are excluded from the diagnosis of dyslexia. However, it is not difficult to speculate that a child with family dyslexia could also have autism either through inheritance or through some environmental factor. The main thing to consider is that it may be much more common that a child with dyslexia has social factors unrelated to autism or a child with autism has reading and writing problems unrelated to dyslexia. In fact, typically dyslexic and autistic children have different cognitive, memory, and perceptual patterns although they […]
New Research: Brain Scans Predict Cognitive Performance [Premium]
“This suggests that individual differences in many cognitive tasks are a stable trait marker.” There’s a new Oxford research study circulating through scientific communities and around the world. From Science (Task-free MRI predicts individual differences in brain activity during task performance), Tavor and collegues applied machine-learning principles to test subjects in a “resting state” to see how they could predict their performances on various cognitive tasks. What was the result? They could predict subject’s responses in 46 out of 47 tasks (and maybe there’s a reason why the 47th one didn’t work…it involved more subcortical activity). Tasks included responses to mental math, sentence and story processing, but also higher order problem solving, social perception, and working memory. The data have a lot of ramifications in […]
This is Your Brain on Words [Premium]
In breaking research from UC Berkeley, researchers have found a complicated filing system when it comes to how we process words that we hear. While listening to stories, individual words triggered tiny activation explosions all over the brain associated with word associations – “Words were grouped under various headings: visual, tactile, numeric, locational, abstract, temporal, professional, violent, communal, mental, emotional and social.” So a well-working human brain responding to stories functions more like a wall filled with stickie notes rather than a linear filing cabinet? Which sounds more like the dyslexic way of wiring? Check out the video explanation below. The finding certainly points out the fallacy of viewing language in simple right-brain-left brain terms, but it does support the complexity of language and the right-left […]
