This assessment has two parts, Part A and Part B. Please complete this assessment in one document. You are required to use headings that stand alone and that are not incorporated into the content of the answers. Required headings have been provided for Part A, but you will need to use the questions from Part B as the stand-alone headings.
The famous “Stroop Effect” is named after J. Ridley Stroop, who discovered this strange phenomenon in the 1930s. For this task, words are printed in various colors. It is easy to name the printed colors of the words if the words are not color related or if each word is the name of the color in which it is printed; however, the task is very difficult when the words are color names that conflict with their printed color, for example, RED printed in blue ink. The discordant information (what the words say and the color of the print) produces interference in the brain. There are two hypotheses that may explain the Stroop effect:
Speed of Processing Hypothesis: the interference occurs because words are read faster than colors are named.
Selective Attention Hypothesis: the interference occurs because naming colors requires more attention than reading words.
The anterior cingulate is hypothesized to play a role in this task. If you wish, you can research images from MRI scans of what happens in the brain during a Stroop Test.
To inform your assessment, you may want to complete the following tasks. You will need someone to assist you.
Open Stroop Handout 1 (linked in the Resources). Ask someone to time this exercise with a stopwatch while you complete it. Begin by naming out loud as many of the COLORS on Handout 1 as fast as you can in 20 seconds. If you make an error, correct it before moving on to the next word. Ask your assistant to keep track of how many colors you name correctly. Write down the results.
Open Stroop Handout 2 (linked in the Resources). Repeat the same task. Name as many colors on the handout out loud and as fast as you can in 20 seconds. Write down the results.
As an alternative, you may use the Internet to find information about the Stroop test, such as a demo video or articles that describe how it works and the various results people who have taken the test have experienced.
After you have finished the two tasks listed above or conducted your own research on the Stroop test, respond to the following. Use the headings below to organize this part of your paper.
Based on your own experience with the Stroop test or the research you conducted about it, explain which of the two tasks above would be harder and why.
Briefly explain the role of the anterior cingulate in audiovisual processing and the symptoms of brain injury to this area. Use the Capella library to research the material and support your answers.
Discuss whether a person with dyslexia or a brain injury would have more or less trouble with this task. Comment on how someone would do on this task if he or she did not speak English. What other observations did you have?
Below are the required headings for Part A of this assessment. These should stand alone and should not be incorporated into the content of the answer:
Which task would be harder? Why?
What is the role of the anterior cingulate in audiovisual processing and the symptoms of brain injury to this area?
Discuss whether a person with dyslexia or a brain injury would have more or less trouble with this task.
How would someone do on this task if he or she did not speak English?
The blind spot is the area on the retina without photoreceptors. Therefore, the part of an image that falls on this region will not be seen. It is in this region that the optic nerve exits the eye on its way to the brain. Humans may use different parts of their brain to discriminate objects from people. In particular, we may have specialized neurons for recognizing faces.
For this part of the assessment, answer the following questions. Use the Capella library to research the material and support your answers. Format your paper by using the questions as headings; do not incorporate the questions into the content of the answers.
What is the problem of final integration of visual information?
What kind of problem(s) does this present regarding our understanding of how the brain works?
Is this a problem that needs to be solved?
What research has been conducted into this issue? Are there any recent papers in the scientific literature that address this issue?
