This document describes the background brain science, the principles upon which the brain games and courses were designed, and some of the research done using Lumosity. The goal was to break down the science of Lumosity into terms that anyone can understand while creating a comprehensive and precise presentation of the research.

Have you ever wanted to take the Lumosity experience with you everywhere you go? Now you can play your favorite Lumosity games and access your favorite parts of the program even when you are away from your computer. With Lumosity Brain Trainer, our 2 million members can now train their brain using their iPhone and iPod touch. For years, Lumosity has worked closely with the world’s leading neuroscientists from top universities — including Stanford, UCSF and Berkeley — to create the best cognitive enhancement program. This complete program is now available for the iPhone platform.

Free to download, Lumosity Brain Trainer includes 35 daily training sessions of 7 brain games designed to enhance your cognitive abilities, including memory, processing speed, attention, flexibility, and problem solving. Playing these brain games a few minutes every day will help achieve the best results.

Just like our online users, our iPhone users will experience the following benefits:

• Improved memory
• Enhanced mood
• Better problem solving skills
• Ability to think faster

Lumosity Brain Trainer also helps you track your progress in each cognitive function using the Brain Performance Index (BPI). By using Lumosity Brain Trainer, you should see your BPI improve overtime.

Existing Lumosity members can access Brain Trainer using their existing accounts and will see their performance reflected in their history and brain profile. New users who are starting with Brain Trainer will have a complete Lumosity experience on the iPhone and will also have the opportunity to further develop specific brain attributes through Lumosity.com.

Memory BPI in Lumosity Brain Trainer

Training with cognitive exercises can improve targeted mental functions, conclude the authors of a review article published recently in the journal Alzheimer’s and Dementia.  The authors (Kathryn Papp and Stephen Walsh from the University of Connecticut and Peter Snyder from Brown University) reviewed ten randomized controlled trials involving cognitive training interventions in healthy adults published since 1992.  They find that specific abilities such as memory, reasoning, and speed of processing can be improved through targeted training programs.  This is an important conclusion, and it is consistent with the growing evidence in support of the effectiveness of cognitive training.

The authors point out that the benefits of cognitive training tend to be specific to the trained domain.  So, if you want improved memory — train on games designed to improve memory.  If you want improved attention — train with attention games, and so on.  The relationship to physical exercise is apparent.  If you want big biceps — do curls.  If you want ripped abs — do sit ups.  Lumosity was designed with these principles in mind.  This is why the site contains over 30 games targeting cognitive functions spanning speed of processing, memory, attention, flexibility, and problem solving — a complete gym for the brain.

It is also clear from this review that there is still much to learn.  Few of the studies have follow-up testing longer than a few months, and many of them lack measures of real-world benefits such as activities of daily living.  However, where longer follow-ups and real-world benefits are measured, benefits are seen to be long lasting and quite general.  For example, in the ACTIVE study of cognitive training in normal healthy older adults, benefits to activities of daily living are seen 5 years after the training intervention ended.

While there is still much to learn, the weight of the evidence is showing that cognitive training can be highly effective when properly designed and executed.

So what does all this mean for you?

As you play some of our newer Lumosity games, you may notice adjustments to your overall BPI, brain area BPIs (such as Memory and Attention), attribute BPIs (such as Visual Field and Focus) as well as individual game BPI histories. For example, playing Memory Match Overload will now affect your BPI for that individual game as well as for the larger categories it is a part of. Lumosity subscribers can check their Memory Match Overload BPI history at any time by logging into lumosity.com, accessing “Your Profile,” clicking on the “History” tab,  selecting “Memory,” clicking the “Working Memory” attribute, and choosing “Memory Match Overload” from the drop-down box. Because Memory Match Overload is a Working Memory game, playing it will affect the BPI for the Working Memory attribute and the more expansive Memory category, as well as your overall BPI. You can check your category and attribute BPI history from the History section within “Your Profile.”

Don’t be discouraged if your overall BPI drops a bit after playing one of our newer games: like all Lumosity activities, practice will lead to improvement, and eventually, a higher BPI. We’ll be integrating games into our BPI system during the upcoming weeks, starting with Memory Match Overload.

We’ll make sure to update this post each time we add another game to our BPI system, so keep checking back!

And as always, if you’re curious about how we calculate BPI scales, or could use a refresher, you can learn more about it here.

UPDATE 12/07/09

BPIs have been added for Playing Koi and Brain Shift Overdrive. Why not play them now?

Can you actually become more intelligent?  For years, neuroscientists thought that this basically didn’t happen.  According to this view, you can take in more information and learn new things, but you can’t really become “more intelligent.”  Recent research conducted by scientists at the University of Michigan shows that this old view is probably dead wrong.

Susanne Jaeggi, Martin Buschkuehl, and their colleagues at Michigan did a study looking at what happens when people play a challenging working memory task called Dual N-Back.  They found that after training on this task for 25 minutes a day for a few weeks, the young adults in their study actually scored much better on tests of fluid intelligence – the ability to creatively solve new problems.  Fluid intelligence is part of standard IQ tests, so we can say that these subjects actually increased their intelligence following this training.

The Dual N-Back training is now available (free for a limited time) on Lumosity!  We have worked closely with Dr. Jaeggi and Dr. Buschkuehl to create a version of the Dual N-Back training that replicates what was used in their earlier study.  And, we’re going to support their ongoing research by hosting the program which will be used in their studies of intelligence training going forward.

Try it for yourself, but be warned: this training is not for the faint of heart. It’s hard! But the effort is worth it. After you’ve started, why not share your experiences with other users in our dual n-back forum?

Give it a try and send some feedback our way; it’s free to all members for a limited time only!

Here’s an example of a touching testimonial that we recently received from Dr. David Darbro. Dr. Darbro suffered from a stroke in 2005, and he now uses Lumosity to regain lost mental function.

“Imagine not being able to speak … you are driving home one night when suddenly out of the blue your speech becomes gibberish….then imagine what it would be like to not be able to remember what number comes after 1,2,3,4,…. That description describes what I experienced in 2005. A week or so after I went into atrial fibrillation I had a stroke that hospitalized me.

Ever since that time I have been working to regain lost mental function. Knowing that about my history hopefully allows you to understand my enthusiasm for your program. Lumosity provides me with a guide that is helping me restore lost cognitive function I suffered on that night in July 2005. Lumosity’s method for cognitive improvement contains games that are fun to take; challenge one’s mental performance; and at the same time encourage one to excel and outdo one’s previous best score.

It has been said that “no pain no gain” is as true in training the body as it is in training the brain. I believe there is some truth to that saying, and is why I work diligently taking these exercises daily and drive myself and sweat over them. The investment in time and effort required to blow out the mental cobwebs is yielding rewards. Exercising my brain to improve my mental status provides me with the confidence to go about my life. I know that nothing great is accomplished without hard work. And I also know that “if you don’t use it you will lose it.” I believe the Lumosity mental tests are keeping me from “losing it”. The tests aim at improving skill in attention, memory, speed, mental flexibility, and problem solving. These five basic skills are needed if we are to function well in today’s fast paced life. Not only am I regaining mental skills during my refreshing mental workout, but also my daily progress is documented. This documentation provides an objective measure of my brain’s healing. I can document the fact that I am regaining previously lost mental function. I am most thankful.

As a medical physician who is oriented to wellness I have a passion to help my patients and others regain lost function as I have done. Because mental functioning comprises a huge part of wellness I purpose to recommend your service to my patients and others. In short, the Lumosity method is a program of mental training that provides we members with a delightful way to prepare for whatever challenges life may have in store during our brief pilgrimage above sod. Thank you all for making this service available to us all.”

From a cognitive perspective, “planning” can actually involve several brain attributes, including working memory, spatial recall, and logical reasoning. With all of these things in play, it’s no wonder that choosing your next few moves in a game of chess can seem like a monumental task.

That’s why we’ve designed Route to Sprout, a new game that challenges you to move a seed to its planting hole using the most efficient path you can find. If you take the time to figure out the optimal route, you’ll earn extra points and give your planning skills a workout at the same time.
