Building Lumosity's First Mobile Cognitive Assessment

The ability to monitor cognitive functioning across the lifespan accurately and remotely remains an essential method for understanding normal, healthy, cognitive aging and cognitive impairment or decline. Mobile, computerized neurocognitive assessments allow for less burdensome and more frequent administrations with minimal learning effects.


Building Lumosity's First Mobile Cognitive Assessment


The NeuroCognitive Performance Test is based on common cognitive assessments. It is an essential component of our ongoing efforts to establish a valid measure of cognition and it is central to our efforts to examine and understand product efficacy. Eventually, we would love to see an NCPT tool adapted to clinical and research environments.




Cognitive assessments have been traditionally administered with pen and paper since the 1930s. Even today, a licensed clinician sits in a room with a patient and administers a series of pen and paper tasks while taking notes by hand and timing the patient with a stopwatch.

Lumos Labs created their first web-based version in 2009, which we now call the NCPT or the Neurocognitive Performance Test, when the idea to do large, online, remote cognitive training studies was born. We used it as a tool to show the efficacy of Lumosity training in the Crosswords study published in 2015. We have provided it as a free tool for research partners and collaborators to help advance research in human cognition. Over a million of our users have taken the NCPT over the years, and we are also able to provide that data for our collaborators.




We need to begin efficacy studies with Lumosity Mobile to understand how the product is currently working and how we can improve.

Our research partnerships support validation and product development. Most of our research partners are requesting a mobile assessment.

MVP: Deliver a comprehensive set of cognitive assessments on tablets for use in a Lumosity mobile efficacy test.

Long-term: Someday, we also hope to offer mobile NCPT to partners for use in clinical and research studies. We also would like to use it in product to help users measure their performance gains after playing Lumosity.

We selected a subset of assessments to port and design for Unity, supporting iPad first with plans to port later to iOS and Android. Before we could conduct an efficacy study or release a consumer version of the app, we first needed to release an alpha version to the App Store in order to collect enough data and perform validation studies on the mobile NCPT and follow up with optimizations as needed.


My Role


The NCPT Team was formed in 2015 and comprised of 1 product manager, two Unity engineers, a research scientist, and myself as Senior Product Designer. My core responsibilities included but were not limited to:

Brand identity
User experience
Task flows
Information Architecture
Usability testing

Interaction design
Visual/UI design 
Game design
Motion design
Spec + asset production

I worked very closely with the product manager and research scientist on all parts of the feature’s development and partnered with Unity engineers during implementation.
