How fast the brain works

For the project I conducted a test with my roommate. For the test I used a standard ruler, a desk, a chair, and my roommate Ethan. The results were the test were very surprising to me.

The test went like this:

1. Ethan sat close to the table where is dominant hand was hanging over the edge.

2. I was holding the ruler to the where the bottom of it was at Ethan's hand and my instructions to Ethan were as soon as you saw the ruler drop catch it.

3. I did this process 3 more times.

4. To add a variable into this test I had Ethan close his eyes and when I said go to try and catch the ruler. I tested this again 4 times.

5. To add a different variable I had Ethan close his eyes again but instead of me saying go I would touch his shoulder to signal to him when to try and catch the ruler.

6. If Ethan did not catch the ruler I put 80 to represent where the ruler would have hit the floor.

Here are the results from all the test:

Visual test:
trial 1                         80 cm
trial 2                         19 cm
trial 3                         18 cm
trial 4                         21 cm

 Auditory test:
trial 1                         80 cm
trial 2                         80 cm
trail 3                         25 cm
trial 4                         24 cm

Touch test:
trial 1                        80 cm
trial 2                        24 cm
trial 3                        23 cm
trial 4                        26 cm

Averages:
Visual test                34.5 cm
Auditory test            52.5 cm
Touch test                38.25 cm

After the test most of the statistics went as I thought they would. The visual test I knew from the get go was going to be the best. But what came surprising to me was the touch test was better than the auditory test. The average for the auditory test was 14 cm worst than the touch test. But that was not the biggest surprise from testing this. The biggest surprised was how fast my roommate was able to catch the ruler on my que. I thought it was going to be a lot slower on how fast he was going to be able to catch the ruler because he was without the main sense he had to use for this test.

The brain has once again amazed me on how it works. To me it is mind blowing on how fast the brain is able to work even if it without one of the main senses.

    wow that is surprising that the touch test was better than the auditory. But maybe if I really think about it, as someone who has cooked most of their life, touching something produces a pretty quick reaction!! sometimes I can hear something in the kitchen when I used to cook professionally and it took much longer to respond. so I can see how that would be true

    This seemed like fun. When reading the directions I could not get a hang of how it all worked out, but now after reading your blog I know feel like I should have went with this experiment with my cousin. Good Job.

Final post

Ending my first year as a college student was interesting. But even with that said I learned a lot about psychology. From this semester I learned how the brain works and psychological disorders. Our first lesson was over brain and behavior. In a Ted talk a scientist talked about how the brain works. I found it interesting that a neuroscientist helped design a exoskeleton suit that helped a paralyzed man kick the first ball at the 2014 World Cup. I also learned about sensation. This involved our 5 senses that we use to be aware of our surroundings and adapt to what is happening. In week 5 we learned about a development of a child. The biggest thing that stuck out to me was the nature vs nurture debate. After that lesson we learned about memory and learning. The studying of memory has blown scientist minds away when they study and look at the brain. Scientist have studied how we receive information and translate that into our memory bank. In module 5 we learned about motivations and em...

Gratitude Visit

I wrote a letter to my youth ministers that are leaving the church that I grew up at and taught me all the years I was in the youth group. Here is the letter. Dear John and Crysty,      There are not enough thank you's I could say to the both of y'all for how much y'all did for me and the others in the youth group as I grew up. I still remember my first Sunday class I ever had in the youth group. John made me stand up and say my name and who was my favorite super hero and of course I was going to say Batman because I knew who was asking me the question. Some of my favorite memories growing up were from youth group events. From Pine Springs, The Houston Mission trip, or even Guatemala. I am still so thankful that I got to experience Guatemala and it wouldn't have been without John and my Dad basically forcing me to go. I learned so many lessons from that trip that I still think about as I write this letter to y'all.      I want to say thank you ...
