In my last blog post I talked about my goal of gathering a large amount of objective data showing that certain types of music (mine, in this case) can have a beneficial effect on attention.
Well, we’re roughly a month into our ongoing Continuous Performance Tests and so far the results are good.
When we built our attention tests, we were focused on trying to make the most accurate, objective test possible. We hoped that we’d see some good results, but lurking in the shadows during the build was the concern that we didn’t really know what the data would present.
I can’t tell you how nervous I was as the first hundred or so tests were taken. I looked at each person’s results and nearly panicked in the few times when someone’s music-stimulated results weren’t as good as their silence score. Thankfully, only a minority of test-takers had this experience, so at least I’m able to sleep at night (as well as I do anyway).
Following is a breakdown of what we’ve seen in the first 24 days of the test. So far, the number of tests taken is greater than the number of subjects in any other study exploring the effects of music on attention or cognition. This alone is a milestone.
Looking at the Test Results
65.8% of the BSR attention test-takers have taken our Symbols test. Because this is our largest sample, I thought this would be a good test to examine first. Here are the details of the results for the period 9/3/13-9/27/13:
Detection errors: The silence (control) condition error rate was 13.15. The BSR music (stimulated) condition showed an error rate of 9.48. This is a 3.67 or 29.7% reduction of errors.
Commission errors: The silence (control) condition error rate was .71. The BSR music (stimulated) condition showed an error rate of .48. This is a .23 or 32.3% reduction of errors.
Omission errors: The silence (control) condition error rate was 6.96. The BSR music (stimulated) condition showed an error rate of 4.77. This is a 2.19 or 31.5% reduction of errors.
Fastest click: For the silence (control) condition the fastest click speed was 334 ms. The BSR music (stimulated) condition showed an average click speed of 351 ms (milliseconds). This is a 17 ms or 5.1% slower click-time.
Slowest click: For the silence (control) condition the slowest click speed was 964 ms. The BSR music (stimulated) condition showed an average click speed of 929 ms. This is a 35ms or 3.6% faster click-time.
Average click: Of the three click speeds the average offers us the best data. For the silence (control) condition the average click speed was 599 ms. The BSR music (stimulated) condition showed an average click speed of 582 ms. This is a 17 ms or 2.8% faster click-time.
What it Means
Across the board, we saw reductions in error rates with the BSR music (stimulated) condition compared to the silence (control) condition. The average error-rate reduction was 31.17% with improvements falling fairly consistently across the three error types. This is a significant change and suggests that BSR music provides increased focusing/attention abilities when played quietly in the background while working.
Where I go from here
We’ll keep collecting data. And we’ll continue to increase our samples by telling as many people as we can about both the test and the results (please share it with everyone you know).
I’ll keep tweaking the music. As part of my goal to keep the music customized, we choose what you hear in the music-stimulated portion of the test based your silence test result and intake form. This means that there are dozens of different tracks used for the test. Our internal A/B test method tracks what works and what doesn’t work as well for you. This will allow us to see patterns in the music’s effectiveness. Making sense of this data requires a large number of tests, so you need to take the test so that we can up the ante on BSR’s customization.
We’ll keep improving your BSR music experience. We tied the test into the music selection algorithms, so your results help determine the type of Focus and Brain Boost tracks you receive when you let us choose the music (in Auto-Select Mode). This satisfies my emphasis on real-world effects rather than pure research. I want you to get the best possible effects from my music. Immediately integrating your test results with the music selection makes this happen. It also provides an incentive for you to take the test.
At some point we plan to test other types of music, including classical and contemporary selections. It will be interesting to compare BSR to the types of music other studies have examined, including that used in the much-publicized Mozart Effect.
We need a lot more data to do all this. So if you haven’t yet taken the test (or taken it today), please jump in.
Not only will you help us learn more about the impact of BSR on focusing ability, you’ll also be able to see for yourself if Brain Shift Radio’s music can help you focus better.
