For example if you write red using blue ink it takes more time to read blue aloud than when writing red using red ink.

This phenomenon is due to the Stroop effect, and the following experiment aim to induce that same effect into the participants and observe the difference between reading the congruent and incongruent words. Twelve participants took part in the experiment. The data collected was analysed using the Inferential Statistical tests method, because this method enable us to assume that the whole population may behave in the same way as the participants in this experiment. The t-test value has been calculated and is found to be equal to 10.48. With this value of t-test, I have achieved a level of significance of
