Imperfect Perception

                 

            Number of Dots                        Percentage Change

Trial 1         36                                                   n/a
Trial 2         39                                               .083333
Trial 3         37                                               .027777
Trial 4         39                                               .083333
Trial 5         38                                               .05555




I think I did pretty well, according to the website only about 8% of people who do the test and say how many they get, did better than I did. The first trial I did was my lowest, although not by much, which was to be expected. As I did the test more, I was able to react a little faster, which made my score go up a little bit. I think I used sense perception and reason by using my eyes to scan the block where the dots where showing up, and processing that in my brain to get the fastest reaction signal to my hands. I think that I had a bit of Signal-Detection Theory because occasionally I clicked a dot that I thought was there, but wasn't, because I was too busy trying to react as fast as possible and made mistakes that way.

I experience different emotions when I listen to music. If some of the lyrics are really sad, or the song is directly linked in my mind to an event that experienced, I may feel extremely upset, angry, happy, or a combination. I also may use reason if I'm listening to a song I've never heard before, trying to make sense of the lyrics, or even language if the song has words I don't recognize, whether they be a different language or just slang words I've never heard.

Occasionally I may see a picture in my head that I relate to a song, but songs don't directly put images in my head or relate to colors.

The Stroop effect is the difference in the reaction time it takes you to say a color, for example "blue", if it is printed with blue ink, and the time it takes if a color, for example "red" is printed in green ink for you to name the color it is printed in. The time to name the color if the word and color do not correspond is longer than if they do correspond.


The interference of stimuli that is not related to what you are focusing on can be very significant. The excess information your brain is taking in makes it longer for you to process what should be a relatively simple task. Other stimuli slows your reaction and can interfere with your "knowing" because it takes time to be thorough and make sure you're only focusing on the important stimuli, and if you rush, it is much easier to make errors.
