Coming Soon: More BPIs!

You’ve been playing our new Lumosity games, and we’ve been working behind the scenes to collect data and generate BPI (Brain Performance Index) scales for them. Now we’re gearing up to integrate some of our more recent games into the BPI system on our site.

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.

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

Working memory training changes the brain

By Gregory Kellett, a cognitive neuroscience researcher at SFSU and science writer for Lumos Labs .

It seems that working memory training may work by physically altering the brain. Stockholm Brain Institute researchers put healthy people through working memory exercises for 35 minutes per day over a period of 5 weeks. Changes in dopamine receptor density were measured with positron emission tomography (PET) before and after the training.

Following working memory training, they found:

• An increase in the density of dopamine receptors.
• An improvement in working memory performance.

The neurotransmitter dopamine plays a central role in working memory. This research implies that improving working memory performance through several weeks of training might work by increasing the quantity of dopamine receptors in the brain.

New on Lumosity: Friends and User Profiles

Today the Lumosity team launched a couple of new features that mark the beginning of a more social Lumosity experience: Lumosity Friends and user profiles.

Now, you can see what your friends and family are doing on Lumosity and what their best cognitive attributes are. If they aren’t already on Lumosity, invite them to join so you can add them as Lumosity Friends.

Also, check out your new Lumosity profile and personalize it with a photo.

There’s a lot more to come; stay tuned in the coming weeks for more ways to communicate and coordinate with the Lumosity community.

You’ll be getting a sneak peek of new game designs starting next week! We’d love to hear what you think at games@lumoslabs.com.

New Brain Game – Top Chimp!

We’re on a roll! Following the debut of Name Tag last month, we are now ready to release Top Chimp, a brain game that sharpens visual attention and trains working memory. We think it’s more fun than a barrel of…well, monkeys, but would love to have your feedback before the game becomes part of the regular set of brain exercises. Please find the game here http://games.lumosity.com/top_chimp.html and send any suggestions to games@lumosity.com.

Brain game development: Lumos Labs raises $3 million

Since we launched Lumosity last year, we’ve heard lots of feedback from users saying you love the brain games, and the feeling of getting smarter and seeing your improvement. One thing many of you have requested is more exercises and games. Well, we’ve just raised $3 million from 2 top venture capital firms, as well as some really smart individual investors, in order to keep improving Lumosity so it’s always the best site for brain training.

Our new partners are FirstMark Capital and Norwest Venture Partners (NVP), and together we will be able to continue our research into how to increase brain performance and maintain brain health in the best – and most enjoyable – ways possible.

The official press release is on the next page.
