## We transform science into delightful games

For decades, researchers have created tasks that measure cognitive abilities.
We’ve adapted some of these tasks and made some of our own, creating cognitive
games. It makes you smarter!

## Dual N-Back

Dual N-Back proven, pass the learning results into another brain activity.
This effect has been confirmed by a number of scientific studies.
“Fluid intelligence (Gf) refers to the ability to reason and to solve new
problems independently of previously acquired knowledge. Gf is critical for a
wide variety of cognitive tasks, and it is considered one of the most
important factors in learning. Moreover, Gf is closely related to professional
and educational success, especially in complex and demanding environments.”

How To Start

The Dual N-Back game field is a square separated to smaller squares with lines
(like 3×3 cross-zero game field).
During the game the image is shown in one of the game squares.
Your task is to find a match of the current position of the image to the
position shown one (or two) step earlier. If there was a match, press the
corresponding match key. Same thing for the auditory letters. Just listen and
try to remember the letters from the previous steps.

Tips For Beginners
There are some points you have to know to do the Dual N-Back task right. Here
is a short list of tips for you to start:
– do it at least 20 minutes a day (30-40 is better) to have significant
results;
– do it at least 5 days a week;
– subvocalizing is bad;
– chunking is not so bad;
– if you get stuck on one level for two or three weeks don’t worry, just keep
going, but don’t forget to:
– push your limits. If you get 80% success rate on the task, move up to the
next level. Don’t try to stabilize a level you are already doing good. Going
out of your comfort zone is the only way to grow.

Real Life Benefits

A lot of people report numerous benefits after doing the N-Back Task, such as:
easier to get a hold of a discussion
better verbal fluency
faster reading with better understanding
better concentration and focus
better dream recall
improvements in piano playing
All these benefits (and there are many others) were taken from the real user
feedback on the N-Back task training.

## Complex Working Memory (CWM)

Complex Working Memory (CWM) is a brain training exercise that improves
working memory and fluid intelligence.
The current implementation is based on the task used for the study “Expanding
the mind’s workspace” by Jason M. Cheyne and Alexandra B. Morrison.
In short, the study demonstrates the success in using the CWM task to improve
working memory, cognitive control and understanding of what has been read.

Overview

The CWM exercise consists of the remembering rounds and the recall stage. The
number of the rounds in an exercise equals to the current level of the CWM
exercise.
Every round in the CWM exercise consists of two parts: the Decision making
part at the beginning and the Remembering part at the end.
There are usually 4 Decision tasks in one round that are followed by an item
to Remember. So, for example, it the exercise level is 5 you’ll have to
remember 5 items in total.
After all rounds passed there is a Recall stage where you have to recall all
the remembered items.
There are two types of the CWM Span Task:
Spatial CWM
Verbal CWM
The Decision and Remembering/Recall parts of the exercise are different for
each type.

Spatial CWM

On the Decision stage of the Spatial CWM you’ll have to make a decision
whether the displayed figure is symmetric on the Y axis. (Symmetric means its
left part is its mirrored reflection of the right part)

Verbal CWM

On the Decision stage of the Verbal CWM you’ll have to make a decision whether
the displayed characters form the correct word.
If the word is spelled correctly press the Yes button (or correspondent key on
the keyboard). If not – press No.
On the Remembering stage of the Verbal CWM you are shown the alphabet letter.
Remember the letter on every round.
On the Recall stage you have to recall the letters in the order they appeared
(by clicking the cells in the grid).

## Mental Math

Mental Math is a brain game for testing / improving your mental skill
calculations.
We do calculations in the mind and improve your attention, working memory and
processing speed.

## Corsi

Exercises Corsi is the implementation of the Corsi Block-Tapping test.
Corsi Block-Tapping is a variant of the memory task. It was originally based
on the Digit Span task, but unlike Digit Span, it requires the use of visuo-
spatial memory.

The process of the Corsi block tapping task requires the subject to observe
the sequence of blocks, and then repeat the sequence back in order. The task
starts with a small number of blocks and gradually increases in length up. The
test measures both the number of correct sequences and the longest sequence
remembered.

This number is known as the Corsi Span, and averages about 5 for normal human
subjects. An fMRI study involving subjects undergoing this test revealed that
while the sequence length increases, general brain activity remains the same.
So while humans may show encoding difficulty, this is not related to overall
brain activation. Whether able to perform the task well or not the
ventrolateral prefrontal cortex is highly involved. Corsi blocks tasks with a
normal forward order requires support from the visuospatial skech pad, but not
from the phonological loop. When the sequence to be recalled becomes longer
than three or four items, central executive resources are used.

## Fastest

Fastest is a reaction rate test.
Knowing your reaction speed, it can always be compared with other people. This
is necessary in order to properly organize their training. If suddenly the
reaction rate began to fall, then urgently increase the number of exercises to
improve the reaction speed. You may not notice how fast the reaction starts to
fall. This often happens with many athletes. Look, a huge number of athletes
performed with success, and then somehow slipped unnoticed to bad results. And
no one can understand what happened. It seems that the physical form is good,
but there are no results.
