In the online stroop task experiment: http://www.psytoolkit.org/experiment-library/stroop.html

I am having difficulty understanding it, in relation to what I am studying. My research paper is on the effect of increased heart rate, on the online stroop task experiment. My findings are, increased heart-rate actually enchances Stroop-Effect Response Time. So what does this all mean, and what would be a written analyze about it?

What do psychology papers say about the effect of stress on stroop effect? And what are examples of such papers..

Thank-you so much.

Explanation / Answer

Note: This response is in UK English, please paste the response to MS Word and you should be able to spot discrepancies easily. Since you require an explanation, I will not be entirely prosaic but more conversation in the response. If you use the explanations below, please make sure to refurbish the answer.

(Answer) The Stroop-effect response time is the difference in time between a compatible response (green is printed in green ink) and an incompatible response (green is printed in red ink). The cause of this difference is simply that the brain is being fed with two different sets of information simultaneously.

For the sake of understanding this experiment, let us consider a case-study. You are writing a history test. You are asked to write an essay question about a certain leader named John Doe. This leader is known for gaining massive rights for the downtrodden of the society, liberating the labour class, saving kittens from high branches and so on. When you write about Doe’s works, your heart-rate is as normal as it should be during a test that requires you to write memorised answers.

The question in your paper that follows this one is about your philosophical views on how John Doe actually achieved all this. He was an extremist, adopted methods of extremely questionable ethics in order to achieve his goals. If you have to answer an essay question about how he tortured members of the ruling party, you will have to apply philosophy and facts. In some cases, you may have to synthesize your response by considering what you have read versus what you have felt.

Now even though answering this question is not one of life’s dilemmas, you will be pondering a bit more on this response and your heart-rate may also increase in comparison to the previous answer.

The difference was that in the first situation, you had to merely make an account of Doe’s reforms. In the second situation, you actually had to merge two opposing sides. The facts and the ethics needed to be deciphered rationally by your brain, in order to produce the correct answer.

Therefore, the reason for an increased heart-rate is a simple case of confusion. Mental confusion and anxiety are catalysts that increase heart-rate. The stroop method only attempts to measure the confusion and put it in an empirical value. When the brain is fed two different types of information, it gets confused; the confusion or anxiety leads to an increased heart-rate. The stroop method tries to determine this measure by measuring the time difference between a compatible and an incompatible colour response.

A good example of such a study is “The context-specific proportion congruent Stroop effect: Location as a contextual cue by MATTHEW J. C. CRUMP, ZHIYU GONG, and BRUCE MILLIKEN McMaster University, Hamilton, Ontario, Canada”
