Shaping Your Thoughts
Our purpose for this project was to find out
if the wrong word of a shape in another shape would effect how fast the person reacted to the outside shape.
Data & Results
If we change the word inside the shape then the reaction time will increase.
Independent Variables: different shapes shown
Dependent Variable: how fast the human volunteer responds
Control Variable: shape with no distraction
Shapes that are printed out
The pressure of answering the questions might result in the human getting angry for not answering with the correct shape

Human volunteer had different reactions from the start of the beginning to the middle point.
When they mess up they tend to go back and their brows furrowed up.
They start reading the word but stop and then say the outer shape.
Some human volunteers seem angry when they get confused about what they are reading and seeing.
Some confuse the words with the shape and keep going other times they correct themselves.
Print out the shapes (shapes, shapes with correct name & shapes with mix names.)
Make sure to cut the paper you printed into strips (horizontally)
Write the number of order behind the strip.
Put strips in different piles.
Turn over the shapes strip (the shapes should be facing down)
Give volunteer strips and record time.
Repeat this over until trials are completed.
Record your results.
The stroop effect (sometimes called the stroop test) is basically a demonstration of meddling in the reaction time of a challenge. The effect is related to the ability of most people to read words more quickly and automatically than they can name colors. For example, if the word is written in a color different from the color itself like for instance “blue” is composed as green we will blurt out the word “blue” more quickly than we can name the color in what it is written, which in this case is “green.”
The different color and the actual word both require more time to be understood. The whole reaction of the stroop effect is because of interference. Interference is a processing delay in the brain that is caused by incompatible functions in the brain.
The word would be the first thing that your brain would think to process. The words have more influence over the colors. There are two theories that scientists have come up with to explain why the stroop effect happens. The first theory, the Speed of Processing Theory happens because the words would be read faster than the colors that would be named. The second theory, the Selective Attention Theory occurs because actually naming the colors requires more attention than reading words.
Two incompatible things combined would result in a slower reaction time than with no distractions. The reaction time could be caused by either rushing or the time it takes to name the colors. These different tests depend on how and where the information is processed. The task of telling what answer you think is correct is processed in the anterior cingulate. The anterior cingulate is associated with the stroop test because you have to make a decision fast and correct.
The process of cognitive mechanism (a general term of thinking) is called directed attention. This resource is used to focus our thoughts by preventing one response in order to say or do something else. In any case, researchers indicates that directed attention is rare and limited mental resource. Another condition is called directed attention fatigue (or DAF) that reduces our mental effectiveness. It also causes irritation and lack of interest that results in thoughtless behavior and impatience that has us making poor decision and focus acknowledge that affects our decisions.
Nothing really majorly dangerous
-Same strip order given to each volunteer
-Same person taking trials every time
It was predicted that if we place distractions in a shape the distractions would cause the amount of time it takes to respond to the correct shape to increase. Our hypothesis was supported by the data we collected because the average reaction time for the shapes with no distractions was less than the average time with the different word placed in the shape. Our ability to read the word inside the shape is stronger than our ability to say a shape. The wrong word trail took the longest because the volunteers tried to speed up but then ended up saying the word instead of the shape.The constant of this project were the same room, same strip order given to each volunteer, same timer, and the same person that will be taking the trial every time.
This means that our hypothesis was valid because that was supported of what we were looking for. What we did in this project is a lot like a stroop effect which basically demonstrates between reaction time of the challenge. We came to the conclusion that most people read words automatically rather than them naming shapes. There are two theories that scientists have come up with to explain why the stroop effect happens. The first theory, the Speed of Processing Theory, suggests that the interference happens because the words would be read faster than the colors that would be named. The second theory, the Selective Attention Theory, suggests the interference occurs because actually naming the colors requires more attention than reading words. But in this case we are were shapes with their names instead of colors and words itself.
We could learn more about why people read faster than they see. One study I would like to do is to take a kid who knows there shapes but not the words and give them the test. I think the results would differ from this study.
According to our results of shaping our thoughts, we found out that the human volunteer had different reactions from the start of the beginning to the end point. When they messed up, their brows furrowed up and some of the volunteers had seemed angry due to the fact that they got confused about what they were reading seeing versus what they were reading. These observations made us realize that our ability to read the word is stronger. The volunteers had the least reaction time with the control study (shapes with correct word inside). The volunteers had the slowest reaction time with the shapes with the wrong word in them.
