  • Do you think, with the differences in the processing of sensory input, all of us experience the world (that is, colors and smells) differently? Is it possible that the perception of sensory input is different for every person? If this is the case, then how can we know if there is a problem with final integration?
  • How does the brain process what we see in the world? Resources

Assessment Instructions 
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. 
Part A 
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:

1.Speed of Processing Hypothesis: the interference occurs because words are read faster than colors are named.

2.Selective Attention Hypothesis: the interference occurs because naming colors requires more attention than reading

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.

1.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.

2.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.
