Accuracy and synesthesia

Comparing texts visually is difficult. We call upon synesthesia to help us. Each number/letter gets its own colour. Go ahead and find the differences! There is a good chance that after a while the number/colour or letter/colour association will become stronger and you will remember numbers like Daniel Tammet.

Symbol recognition

This is a pretty common exercise for “fast thinking” check-up. You need to notice the numbers within the letters and recognize them correctly. Try running the exercise faster, up to 100msec per symbol. This exercise will definitely help you speedread and potentially may help suppressing vocalization.

Multitasking computations

It is notoriously difficult to multitask. In this exercise you calculate the sum of the numbers of the same colour e.g. red with red, green with green. The idea is to keep in your head outputs of previous computations per colour, and update them with each new result.
