Function-based interventions for LD?

Most readers are likely familiar with the idea that one can, by carefully assessing the antecedents and consequences of a problem behavior, essentially determine what is causing that problem behavior to occur. Given that at least some—many?—students with Learning Disabilities (LD) have some problem-some behaviors, wouldn’t it be cool if there was an evidence base about using functional analysis techniques to document development of procedures for addressing the problem behaviors of students with LD?

In “A Systematic Review of Function-Based Interventions for Students with Learning Disabilities,” Professor John McKenna and his colleagues examined the research literature in search of that very evidence base. They were able to locate only a few studies that met the most rigorous standards, but those studies allowed them to conclude that this idea is a promising one. Here’s the source and the abstract with a hot DOI. I think the publisher (Wiley) may be allowing public access to the entire article, so try clicking on the PDF to download it. (I can’t tell, ’cause I’m working from my office, which has free access anyway; drop a comment to let me know.)

Students with learning disabilities (LD) experience pervasive academic deficits requiring extensive academic intervention; however, they may also engage in problem behaviors that adversely affect teaching and learning, thus lessening the potential impact of specialized instruction and supports. The learning deficits of students with LD are prevalent in the extant research, but behavioral needs appear to receive less attention. The authors report the results of a systematic review investigating the evidence-base for function-based interventions for students with LD using the What Works Clearinghouse (WWC) criteria for evaluating single-case studies. Fourteen studies with 17 participants met inclusion criteria, with the majority occurring in elementary settings. Although interventions tended to be effective, few included maintenance and generalization measures. Because of the small number of studies (n = 4) that met WWC design and effectiveness standards, the authors conclude that function-based interventions, although promising, cannot currently be considered an evidence-based practice for students with LD. Implications for practice, areas for future research, and study limitations are reported.

Testing genetic causes of dyslexia

Although at least four genes have been identified as possible markers for dyslexia, scientists have encountered considerable difficulty in coming to consensus about identifying a culprit as a contributing cause for the perplexing reading disorder. As noted previously here on LD Blog, DCDC2 (1 November 2005) and DYX1C1 (1 August 2008; 19 November 2009), among others, have been cited as possible loci for disruptions. But problems emerge when seeking to connect studies that point toward these candidate genes and studies showing the individuals with the problems. The associations between genes and problems appear in some language populations, but perhaps not in others, making one wonder about the clarity of the relationships.

Seeking a means of examining the relationships at a more abstract level, a group of European researchers collected data from a sample of individuals with dyslexia that represented people from eight different countries (Austria, France, Germany, The Netherlands, Switzerland, Finland, Hungary, and the United Kingdom). Using this diverse language sample, they reasoned, would allow them to search the the connections between genes and dyslexia at a more abstract level than when testing with a sample of people speaking just one or two languages.

Visual differences are a consequence, not a cause, of dyslexia

In an article to appear 10 July 2013 in Neuron, Olumide Olulade, Eileen Napoliello, and Guinevere Eden present a series of studies that greatly help educators, psychologists, neurologists, and others understand the relationship between visual deficits and dyslexia. Although most people interested in reading have understood that problems with phonological processes undergird dyslexia, personal accounts of those with dyslexia and some anomalous evidence about the visual cortex and the performance of individuals with dyslexia on certain visual tasks kept the possibility of a visual component open to debate. Professor Eden’s group devised studies and collected the data that shed light on these issues.

In a nutshell, in their first study, Eden’s team found the same results that others had found: When their participants with dyslexia were compared to similar aged children, they showed certain deficits in visual processing associated with a particular part of the brain shown by fMRI. However, when their participants were compared with younger children of like reading ability, there are no deficits in the visual performance; so, these children must not have had the visual problems all along. In their third study, the researchers provided even stronger evidence: The provided powerful remedial reading instruction to their participants and they observed not only improved reading outcomes, but they also found that the students had improved performance on the visual tasks as reflected in fMRI. (Click the accompanying image for a movie of Professors Eden and Olulade explaining the experiments.)

Here is the abstract:

Developmental dyslexia is a reading disorder, yet deficits also manifest in the magnocellular-domi- nated dorsal visual system. Uncertainty about whether visual deficits are causal or consequential to reading disability encumbers accurate identifica- tion and appropriate treatment of this common learning disability. Using fMRI, we demonstrate in typical readers a relationship between reading ability and activity in area V5/MT during visual motion pro- cessing and, as expected, also found lower V5/MT activity for dyslexic children compared to age- matched controls. However, when dyslexics were matched to younger controls on reading ability, no differences emerged, suggesting that weakness in V5/MT may not be causal to dyslexia. To further test for causality, dyslexics underwent a phonolog- ical-based reading intervention. Surprisingly, V5/MT activity increased along with intervention-driven reading gains, demonstrating that activity here is mobilized through reading. Our results provide strong evidence that visual magnocellular dysfunc- tion is not causal to dyslexia but may instead be consequential to impoverished reading.

Ingvar Lundberg: 1934-2012

Ingvar Lundberg—an internationally renowned psychologist who studied the psychology and pedagogy of reading and writing, learning disabilities such as dyslexia and dyscalculia, and problems in language development—died 23 April 2012. He was 77 years old.

Born in Stockholm 30 September 1934, Professor Lundberg began his academic career after teaching elementary school in the 1950s. He completed undergraduate and graduate training in the 1960s at the University of Stockholm and then began his academic career in the department of psychology at Umeå University in 1967. In 1995, he moved to Göteborg University and held dual appointments at Åbo Akademi, Finland, and Bergen University, Norway, during his tenure there. At the time of his death, he was Professor Emeritus in Psychology, University of Gothenburg, Sweden.

Although Professor Lundberg’s research ranged across many areas of psychology, we remember him here especially for his work on learning disabilities. He was a long-time member of the International Academy of Research in Learning Disability and the Society for Scientific Studies in Reading. As a perusal of the accompanying selected list of publications will show, he contributed a lot to our understanding of reading processes and problems.

As the beginning of school approaches, many schools will be considering what to do about bullying, a problem the plagues many students with Learning Disabilities (LD). But, what do we know about the connections between special ed and bullying? Can bullying mess up a student’s IEP? Here’s a little background and some suggested resources.

As one might suspect, one of the difficulties for students with LD is that they are perceived as victims of bullies. Nabuzoka and Smith’s (1993) analysis of sociometric data from ~180 pre-adolescent students, about 20% of whom had LD, showed that those with LD were more likely to be victims of bullying than their non-disabled peers, despite not being judged more aggressive. Estell et al. (2009) reported that teachers considered fifth-grade students with high-incidence disabilities likely to be victims of bullies. However, both teachers and the students’ peers rated them to as likely to be bullies. Those students with disabilities who behaved aggressively were the ones who were more likely to be nominated as bullies.

Subtyping LD

Have you been hearing a lot about subtypes of LD lately? Perhaps it’s just that I’ve been especially alert to it, but it seems I’ve heard a lot of mentions about subtypes of Learning Disabilities in the last few weeks. I want to write a longer, more thorough discussion of the topic, but I’ve found myself repeating a few foundational comments, so I thought I ought to post them here and let others have a go at them.

First, the idea of subtypes of LD is essentially a given. It has to do with the heterogeneity of LD. Because LD is essentially an umbrella category for a diverse array of learning disabilities (note the plural), there are bound to be subgroups. Some students will have problems primarily with reading, some primarily with arithmetic and mathematics, some with writing, others with combinations of these. That makes for lots of subgroups right there. That is, one could start with dyslexia, dyscalculia, and dysgraphia!

Dyscalculia gets good ink

In the prestigious journal Science, Professors Brian Butterworth, Sashank Varma, and Diana Laurillard published a review article discussing dyscalculia, the Learning Disability that makes arithmetic and mathematics an especially- miserable muddle for some students. In their review they explain why mathematical problems are important to individuals and society, what dyscalculia is, what neuroscientists know about mathematics and dyscalculia, and what they see as the outlook for dyscalculia.

Reading comprehension help for ADHD high schoolers

In “Improving the Reading Recall of High School Students With ADHD,” Joseph W. Johnson, Robert Reid, and Linda H. Mason report the results of an intensive study in which they examined the effects of teaching high-school students a comprehension strategy as a part of a self-regulated strategy development model. They found that systematically preparing the students to use what they dubbed the “Think Before Reading” (TWA) strategy helped the students with recall of passages’ main ideas and details connected to them.

Students with attention-deficit/hyperactivity disorder (ADHD) often have difficulty with reading comprehension. This multiple baseline across participants design with multiple probes study examined the effectiveness of a multicomponent reading comprehension strategy (TWA: Think Before Reading, Think While Reading, Think After Reading) taught following the self-regulated strategy development model on social studies expository text recall of three high school students with ADHD. Results showed improvement in the number of main ideas and percentage of supporting details recalled. Gains were maintained and some improvement occurred at 2- and 4-week follow-ups. Implications for future research and practice are discussed.
