In a technologically savvy, hyper-caffeinated, on-the-go society, it can be nearly impossible to ignore distracting information. With flashing lights to deafening sounds, even our smartphones demand attention. How does the mind sort through these conflicting signals, allowing us to concentrate and process only the most important visual cues?
Ignore That! was developed by Dr. Joshua Hartshorne, a post-doctoral fellow in the Computation Cognitive Science group at MIT. Part of the Games with Words project, citizen scientists explore how the brain chooses an appropriate response when faced with conflicting information through a series of simple, 3-minute tasks. After providing your age, gender and handedness, participants identify the color of a word (white or orange), rather than the word itself, then the location (left or right), not direction, of a series of arrows. According to Dr Hartshorne, “Sometimes, it’s really hard to ignore information even when that information is irrelevant. We’re trying to understand what factors go into this… At what age are people best at ignoring irrelevant, distracting information? What about men vs. women? Or left-handers vs. right-handers?”
Known as the Stroop effect, these selective attention tasks help psychologists understand how the brain evaluates information. In the 1930s, John Ridley Stroop observed that reading words was a lot easier than reciting their color. When a word’s meaning is coupled with distracting information, such as a color, two different regions of the brain are stimulated. The right side automatically decodes letters and reads the word. The left consciously analyzes the color. When you are asked to read the color (active) rather than the word (passive), the brain becomes conflicted – the interfering data of the word slows down your response time; relying on the anterior cingulate to choose the correct visual cue to base your answer on. As one of the most famous experimental psychology experiments of all time, similar tests are used clinically to assess brain damage, dementia, mental illness, and famously the effects of altitude on Everest climbers.
Since its launch in November 2012, nearly 1100 citizen scientists have played Ignore That! exploring how our minds work. “I keep doing Stroop demos on myself because I feel like if I concentrate harder, I should be able to block out the effect.” Dr. Hartshorne reflects. “But it’s impossible. That amount of concentration doesn’t exist. Which itself is a bit of mystery: Is this an example of a failure of evolution or is it actually good that we are distractible in this way?”
Shiny, shiny, look at the shiny… How distractible are you? Can you control your mind to read the colors while blocking out the words?

It’s likely you never expected to aid cutting edge cancer research by playing computer games, but the makers of NanoDoc are asking citizen scientists to do just that. By designing nanoparticles – tiny clusters that are made up of only tens to thousands of atoms – and running simulations of how they interact in the body, players can help expert bioengineers overcome challenges in cancer treatment.
Nanoparticles are promising options for cancer treatment because they can be altered in many ways to target cancer tumors without harming healthy tissue. For example, nanoparticles can be designed to interact only with cancer cells or engineered to deliver medicine to affected areas of the body. The problem bioengineers face is that there are too many combinations of nanoparticle alterations to physically test how each one will behave in the body. To address this, Prof. Bhatia’s lab at MIT developed NanoDoc as a way to crowdsource simulated solutions.
The lead developer of NanoDoc, Dr. Sabine Hauert, states that the program “lets the crowd do the legwork” of testing the different nanoparticle solutions through a fun and educational simulation game. Participants start by playing through various training scenarios, working on challenges that have been previously solved by experts. At each level, the players learn a new skill, which allows them to alter the simulated nanoparticles in new ways. Hauert describes, “Its really a cool stepwise process. You get little diplomas at every step.”
Following the training, players are ready to address NanoDoc challenges, which are unsolved problems proposed by bioengineers. Hauert notes that the advantage of the going through the training first is that it prepares players to “go ahead and start working on the problem right away without an engineer,” enabling individual participants to make real contributions. The participants’ solutions are evaluated based on their scores in the game, and the highest scores are carefully evaluated for their potential to test with physical systems. More of these challenges will be available in the coming weeks with the release of the new version of NanoDoc, which will allow for any user to submit new challenges.
So start your NanoDoc training today and join in the challenge! Your high score could lead to tomorrow’s cure.

Pictures, puzzles, and play. Citizen Sort is a collection of interactive games in which players sort and classify photos of unidentified animals. The project is the brain child of researchers at Syracuse University School of Information. The goal is to enable scientists to use pictures of wildlife from the web to help them study changes in species populations, the health of an ecosystem or the effects of urbanization.
Just as scientists might do, the games teach you to group images based on different physical traits such as an animal’s fin shape, skin coloration, or tail length. By sorting the images into specific trait combinations it is possible to identify an animal’s species.
In Happy Match, players are asked to classify pictures of sting rays, moths or sharks. The game starts with a set of pictures. In each consecutive round, you receive a different trait to sort by. At the end, you learn how many pictures you successfully identified. The more you play the more challenging the sorting. You can challenge friends and family to see who the best sorter is.
Another game, Forgotten Island incorporates image sorting into an interactive puzzle. Players find themselves on an isolated island, confused and disoriented after an unfortunate lab accident. Forced into labor by the island’s malevolent robot, and aided his slightly nicer brother ‘bot, the players must use their image matching skills to solve the mystery of the island.
While it is all fun and games for the player, the Citizen Sort project is an experiment it is own right. The project is a model for how game play and scientific research can be combined to make citizen participation more accessible and inviting. So sharpen up those eyes and get sorting.

Human beings are remarkably capable animals when it comes to pattern recognition. The human ability to quickly and accurately recognize recurrent patterns is a skill that numerous citizen science projects have put to work on large, difficult data sets. Galaxy Zoo uses these skills to assist with the morphological classification of galaxies. Pattern recognition and also spatial reasoning contribute to the success of the protein folding project Foldit. Another project aims to take advantage of these human skills and, like Foldit, does so with a game.
Fraxinus is a game created by The Sainsbury Laboratory (TSL) to help researchers address ash dieback in the common ash tree (Fraxinus excelsior). Players attempt to match a nucleotide sequence to a reference genome to look for sites of variation. The game was designed for the social media platform Facebook and allows users to play the game as they would any other on the site. However, this game provides more than entertainment. Fraxinus also provides scientists with small pieces of data that can be aggregated to provide a better understanding of the mechanisms that protect some common ash trees while others perish.
With more than 10,000 puzzles to solve in the game there is a significant amount of work for citizen scientists, but already each of these puzzles has been examined, according to a recent report on the game. Now that each puzzle has been looked at, players will begin to “steal” patterns from one another, in an attempt to increase their game score, and at the same time they will help refine sequence patterns, which in-turn provides better quality data for researchers.
