This ‘How to’ applies to 2-back level.
When you press the “Start” button, the application will begin.
Notice that 2 things happen: A box appears and an audio recording of a letter is played.
Remember where the box appeared and also remember the letter. After a few seconds, another box appears and another letter is said. Remember these, too. You need to remember if a letter was repeated or a box appeared in the same location 2 times ago. In our example, if the third letter said is the same as the very first one, that’s an audio match. If the box appears in the same location as where the first box appeared, this is a visual match. Press “Video” for visual matches, “Audio” for audio matches and both when both match. Continue to press these keys whenever the present squares/letters match what appeared/was said 2 times ago. Eventually, you’ll be good enough that use can go to play 3-back. In 3-back, press the matching keys whenever the letter/square matches what was said/displayed 3 times ago. As you progress, the application will detect this and continue to increase the difficulty to 4 times, etc if you set the ‘Auto-Adjust N-Back’ on.
Be aware that this is a difficult application. At first, it will be difficult to press the correct buttons. Don’t worry. It was the same for the research subjects when they first started. However, after enough practice, the subjects improved in this task (as well as on measures of intelligence).

In psychology, fluid and crystallized intelligence (abbreviated Gf and Gc, respectively) are factors of general intelligence originally identified by Raymond Cattell.
Fluid intelligence is the ability to find meaning in confusion and solve new problems. It is the ability to draw inferences and understand the relationships of various concepts, independent of acquired knowledge.
Crystallized intelligence is the ability to use skills, knowledge, and experience. It should not be equated with memory or knowledge, but it does rely on accessing information from long-term memory.
The dual n-back task was proposed by Susanne Jaeggi et al. in 2003. In this variation, two independent sequences are presented simultaneously, typically using different types of stimuli, such as one auditory and one visual.
In a 2008 research paper Jaeggi et al. claim that practicing a dual n-back task can increase fluid intelligence, as measured in several different standard tests. This resulted in some attention from popular media, including an article in Wired.
In 2009, it was reported in Science that ’14 hours of training over 5 weeks’ led to measurable density changes for cortical dopamine neuroreceptors.
