effect has been widely used in psychology. Among the most important uses is the
creation of validated psychological tests based on the Stroop effect permit to
measure a person’s selective attention capacity and skills, as well as their
processing speed ability. It is also used in conjunction with other
neuropsychological assessments to examine a person’s executive processing
abilities, and can help in the diagnosis and characterization of different
psychiatric and neurological disorders.
the Stroop effect can help to strengthen our reaction, left brain and right
brain. Because when we read the words, your right brain tries to say the color,
while the left brain insists on reading the word.
also use the Stroop effect during brain imaging studies to investigate regions
of the brain that are involved in planning, decision-making, and managing
We can read
the meaning of words quickly. It is already an automated process, because we
knew it before. Therefore, when we change to read the “color”, the “meaning”
will disturb our original cognition, and make our reaction time longer. The
reason is the parts of our brain deal with the color and word’s meaning are
we don’t know the character at all, the result will be different and simple.
For example, if a person totally has no contact with Korean, he/she will read
the word’s color smoothly without interference. There is an interesting
experiment call “How To Catch A Russian Spy”. In the Cold War period, CIA wants
to catch a Russian spy, but spy has an authentic American English, so they used
the Stroop effect that the characters are printed in Russian. Finally, only the
spy spends more time to read the Russian part because for American people who
didn’t know Russian he/she can only read the color. But for the spy, like the
result of Stroop effect, his/her native language interfere brain to transform
the language and said the word’s color.
