STROOP EFFECT internal asse. part one

Throughout time physicological advances have permitted our knowledge about humans grow. Once we start to wonder and question ourselves about the functions of our bodies we come to realize that the brain muscles and other body parts have helped us evolve over time. One of the most important experiments in history is the Stroop Effect, conducted by John Ridley Stroop in the 1930’s. What’s really important is the demonstration of interference in the brain through this experiment; this experiment shows the true capacity of mental flexibility. Interference is the process by which the brain is trying to sort two different concepts or ideas. This in the case of this experiment would be shape and color. This causes a delay in your brain. There are two theories that support the Stroop Effect “Speed of Processing Theory: the interference occurs because words are read faster than colors are named. Selective Attention Theory: the interference occurs because naming colors requires more attention than reading words. “ Both of these theories help explain the experiment. Its important also to state it importance in neurophysiology. When given the word and the color the process in which one has to identify both of the is called the anterior cingulate. This part of the brain lies between the frontal left and right part of the brain, which also involves the emotions and thoughts one receives. The true process of this experiment by hand is through simple task. It involves the handing out of a paper contains various words shaded in the colors they aren’t truly. For example in this experiment the paper would have written purple and had shaded it pink. You are later asked to please say the name of the word that you see without having previously analyzed it. This is the part in which interference takes part and truly works its way to complete the assignment, although taking way longer. Although this may sound quite easy it is contrary to that completely, this is one of the most difficult experiments to explain. Researchers have developed through time a hypothesis to this experiment concluding that “words are processed better than colors” . But we have come to realize that it has to do with response compatibility. In search of removing the color interference that we obtain others have created matching color experiments like the ones of Pritchatt(1968) and McClain(1983) with the use of colored buttons. Stroop interference has been greatly impacting to the world and most definitely to the branches of psychology.
