Transcript of Right Brained vs. Left Brained: Do they see optical illusions differently?

Results Conclusion Right Brained Vs. Left Brained:
Do they see optical illusions differently? Procedures Six optical illusions and a reliable right brained vs. left brained test were found on the Internet. (Images as shown below) However, in general the results of this experiment showed that on the images, it took both of the dominances about the same amount of time. The times did not differ dramatically. Through this experiment, I have discovered that brain dominance is not linked to how you perceive images such as optical illusions. Here are the two reasons why:

There have been theories that say that brain dominance is actually a myth.
Optical illusions are caused by movements of the eye, not the brain. By Ashlee Trotter
5th hour/ CPBio I believed that people of right brained dominance would be able to see the illusions easier.
This is because of the fact that they are known to be more open-minded and creative than the logical left brained thinkers. The goal of this experiment was to see whether or not brain dominance is related to how a person perceives optical illusions. Illusion 1: Illusion 2: Illusion 3: Illusion 4: Illusion 5: Illusion 6: A group of people were given the dominance quiz. The subjects were then sorted into two groups based on their brain dominance. Ten people of each dominance were chosen to go onto the next part. Each subject was brought into an area where they were each shown six different optical illusions, each of which had two possibilities of what could be seen. The subjects were timed to find out how quickly they saw the first image. They continued to look at the illusion until they found the second image, which was also timed. The person showing the illusions recorded the brain dominance of the subject (as previously tested) and how long it took the subject to see both images. These procedures were then repeated with the other five optical illusions. Once the subjects were categorized according to dominance, the average time that it took for either categories to see the first image and the second image were found for all six illusions. The average time of how long it took the subjects to see the second image after they found the first image was also calculated and recorded. Illusions used in experiment It is helpful for a person to know his or her brain dominance in order to understand their strong/weak points. The brain dominance theory was first discovered by Nobel Prize winner Roger W. Sperry while he was studying the effects of epilepsy. Brain Dominance Traits Right brain: intuitive
creative often unorganized
no concern for priorities
depend on their "gut" Left brain: logical
tend to make lists priorities are important
use rules
do tasks in order Although Sperry was correct when he stated that the left hemisphere controls language, it is now known that the right side also contributes to language through intonation and emphasis. A healthy brain has to have both halves operating together in order for a person to process information and complete tasks. Is Brain Dominance a Myth? Therefore, the brain dominance theory is incorrect. What are Optical Illusions? Optical illusions are any illusions that trick the human visual system into either seeing something that is not actually there or incorrectly perceiving it. Can occur naturally or be created by visual tricks Types of Illusions Eye or Brain? Studies at the Barrow Neurological Institute and the University of Vigo show that there is a direct connection between the false motions of optical illusions and tiny eye movements know as microsaccades. Mark Changizi has also discovered that it is the visual system that causes illusions because neural delays in the eye. These neural delays attempt to guess what will be seen in the illusions, which in turn misleads the brain. For Illusions 2, 4, and 6, the people of right brained dominance saw the illusions slightly quicker than the left brainers. Physiological and cognitive are the two main types. Cognitive branches into several types: ambiguous, distorting, paradox, and fictional All of these illusions fall into the category of visual illusions, which causes confusion between what is reality and what is not. Meanwhile, for Illusions 1, 3, and 5, the left brain dominant subjects saw the illusions slightly quicker than the right brain dominant subjects. The End!
