When studies are not needed

Monday, August 29th, 2016

By Siegfried Othmer, PhD

studiesRecently a study showed that some people react badly to statins. Statins have been in use for twenty years, and if some people respond badly to them, then that has also been a fact for about the same number of years. So why was a study needed? And if a study was needed, why did that same reasoning not prevail many years ago? It’s surely not that the facts have been changing. Rather, it was becoming increasingly difficult to ignore the facts that we have already known all along.

Brain Hacking

Brain Hacking by Siegfried Othmer, PhDThe June issue of The Atlantic Magazine features an article on brain hacking by Maria Konnikova. The article reviews various technology options that give some hope of sprucing up brain function. First of all there are the smart pills. Already the stimulants are finding use beyond their medical applications in boosting test performance among college students.

Interpretation of the Reaction Time Distribution II

Wednesday, March 5th, 2014

by Siegfried Othmer, PhD

EEG Info NewsletterI n the previous newsletter it was established that the outliers in the distribution of reaction times could not be interpreted as the tail of the Gaussian distribution. They had to be treated as a distinct phenomenon. When it came to characterizing the distribution function that characterizes the outliers, the analysis suffered from insufficient data. After all, reaction time outliers are relatively rare, so even a database of over 1500 did not give us enough to work with.

Recent Critical Studies of Neurofeedback in Application to ADHD

Wednesday, March 5th, 2014

by Siegfried Othmer, PhD

EEG Info NewsletterA research group in the Netherlands has recently published two neurofeedback studies that failed to corroborate the claims for EEG-informed “Theta/beta” neurofeedback in application to ADHD. The first one of these of which I became aware had relied on parent and teacher ratings to establish progress (van Dongen-Boomsma et al., 2013). Such a study is easy to critique. After all, we have learned not to rely too much on parental observations on their ADHD children in our work. Is that really the best that can be done in the context of a carefully done study? Why not rely on some hard data from neuropsychological testing, for example? Well, it turns out that that was done also, and that was reported in the second paper (Vollebregt et al., 2013). Therein lay the answer that would be much more definitive. Alas, the outcomes were not favorable either. The experimental group did not distinguish itself from the control group in any meaningful way on any of the chosen tests. The tests had been selected with specific characteristics of ADHD in mind.

A Mom’s Journey Through ADHD

Wednesday, November 27th, 2013

by Lorrie Fisher

EEG Info NewsletterADHD? How could that be? My son would engage in video games for hours with no break in concentration. Robert wasn’t wiggly in class like the other ADHD kids. In fact, I suspected that ADHD might be a myth — an excuse for poor teaching or lack of parental discipline. I couldn’t understand how parents would let anyone put their kids at risk with narcotic drugs, no matter how unruly their behavior. All in all, I held a fairly typical attitude.
