These are two questions I’ve been exploring for the last three decades. Initially because I had a hard time staying focused and ultimately because I saw such huge changes in my (and others’) focusing abilities listening to certain types of music.
How do you validate it, though?
This became the persistent question I confronted these last few years, especially after accumulating tons of data and thousands of positive user experiences.
After the launch of my streaming music site, Brain Shift Radio where we noticed that almost half of the listening done was for focus, I began exploring quantitative measures that we could use to see unequivocally whether music can contribute to enhanced focusing abilities.
As it turns, out two independent studies recently conducted in the Netherlands on REI (the core technique behind my music) used Continuous Performance Tests (CPTs) to test attention. Both studies showed significant improvements while listening to my music versus either a placebo recording or silence.
So we looked closely at CPTs and they seemed like a good option. I was drawn to these types of tests for several reasons:
Continuous Performance Tests come in a few varieties. You have auditory and visual, and you have different types of triggers. The auditory tests were off the table since we would be examining the effect of music on attention and the music would compete with the auditory trigger. This left us with choosing different visual trigger options.
Like all our software, we built the framework first, leaving ourselves open when it came to choosing trigger options. We tested a ton of different triggers and decided to offer two types: symbols or numbers. Both use the same timing, variability, and duration. Where they differ is in how quickly people are able to process the stimulus. Symbols – in our case various colored squares – are easier/quicker to process, whereas a series of six numbers takes more cognitive resources.
This makes the symbol test a little easier and also makes it a good place to start. The numeric test will result in higher error rates than the symbol test but, as we’re seeing after a few hundred tests, the relative changes between the silence and music portions of the tests are virtually the same.
Here’s a quick breakdown of our two tests types:
Symbol test (left, top image): This test displays a series of 6 randomly colored squares. When a white square appears in the group, tap the left button or the left arrow key on a keyboard. When a black square appears in the group, tap the right button or arrow key. If neither white nor black appear (pictured) you do nothing.
Numeric test (left, bottom image): This test presents a series of 6 numbers. If a 0 appears in the group (pictured), you tap the left button or left arrow key on a keyboard. If a 1 appears, you tap the right button or arrow key. If neither a 0 or a 1 appear, you do nothing.
Pretty simple. The trick is that speed is important. You need to act quickly because the stimulus only shows for a short time.
Our attention tests are divided in four sections: An intake questionnaire, a test with silence, an intermission, and a test with music. Here is a breakdown of each of these sections:
Once you’re finished with the entire test, we tally your scores. You will find two graphs, each presenting different data sets.
Raw Scores (left). The first are your raw scores. Here you will see each error type – detection, commission, and omission – and your response times – fastest, slowest, and average. Here’s what each error type means:
This data can give you insights into your performance and whether you trend toward being inattentive or impulsive.
Weighted Scores (below). The second score is your weighted score. This balances your various errors against one another and factors in your response times.
Weighted Scores show you how you focus with and without BSR music. Lower numbers mean better focus.
The difference between these scores shows your performance, or more accurately, the music’s ability to help you perform.
In most cases, you should see a lower score for the music portion of the test, showing fewer errors and faster response times (as shown at right).
We’re finding that there are instances when a test-taker has not heard the BSR music before that his scores are not better on the music portion of the test. Past research has suggested that it can take up to 17 minutes for people with no experience with REI to see benefits.
To test this theory we are asking people who scored as well or better in the silence condition their first time that they either take the test again or listen to Brain Sift Radio for a couple of days before taking the test a second time.
Based on people’s responses to these two approaches so far, we’re seeing that the second test usually falls inline with the results we see from people who do respond positively to their first test.
We worked very hard to make the tests accurate by addressing the deficits and limitations that many attention tests have. Here is a look at the major areas we had to address:
Because of the databases and framework we have set up, we have the ability to parse the data in a variety of ways and hopefully see some patterns that we may not even consider at this time.
We have also built this test with the ability to rotate different music, even (gasp!) someone else’s.
The Brain Shift Radio CPTs are for more than just showing you how our music can help you focus. We are also using the data to help us understand how you focus so we can better choose great mixes for you. This data can be stored in your profile if you wish and we will draw from it whenever you choose the Focus or Brain Boost categories in Auto Select mode.
If you log into your account (trial or subscription) when you take the test, we’ll keep track of all your results and you can periodically take the test again to track your progress and make sure you’re getting all you can from BSR.
The Brain Shift Radio attention tests are compatible with both web and mobile devices.
A new article about Brain Shift Radio was just published by theSOP.org. SOP stands for Student Operated Press and this organization is a place where a lot of cutting edge student journalism happens. Check it out.
Here’s a short excerpt:
Web App Helps College Students Enhance Academic Performance
ADHD prescription drug abuse among college students is a known concern among campus officials. The percentages vary, yet studies show that illicit ADHD drug abuse rates may be as high as 34% of a campus student body. Students use these `smart` drugs to improve their concentration, help them cram for exams, and enhance their overall academic performance. The Strong Institute, a leader of auditory brain stimulation programs for individuals with neurobiological disorders, has a solution: Brain Shift Radio offers students the ability to improve their focus without the use of drugs.
The core technique used in Brain Shift Radio was developed from the Strong Institute`s 30-plus years of research exploring how auditory brain stimulation can enhance cognitive function. Called Rhythmic Entrainment Intervention (REI), their technique has been proven to be nearly twice as effective as 20mg of Ritalin for focusing. Other studies show improvements in anxiety, sleep, and cognition, among other areas. For nearly two decades, REI has been successfully used for longterm improvement in stress reduction and increased focus.
“Simply put, you can take control of your brain without the use of drugs,” said Jeff Strong, cofounder of Brain Shift Radio.
