Review of Literature
Introduction:
Optical illusions are usually described as visual images that differ from reality. The eyes and brain “sees” something that does not really match the physical measurement of the image. Optical illusions can function in many ways, they can be images that are different from the objects that make them up, they can also be ones that come from the effects on the eyes and brain through excessive stimulation, and others where the eye and brain creates unconscious inferences. For my science fair project I will be seeing if gender affects visual selective attention. I picked this project so that I could learn more about the science of humans and other animals by means of observable response and the interpretation …show more content…
There’s fast thinking and slow thinking. When your brain figures out an optical illusion your fast thinking part of your brain can't stop seeing the illusion. On the other hand, when you see a multiplication problem you automatically know that you're able to solve it, but if you actually solved it your muscles will tense, your pupils will dilate, and your heart rate will increase, those are effects of slow thinking. No one knows why, but many people with perfect vision don't see what they're supposed to see in an illusion. Each of our eyes has an area where there are no receptors. In other words, there is no organ or cell able to respond to light, heat, or other external stimulus. This area is where the retinal ganglia as the optic nerve. The retina is located on the back of the eye. The purpose of the retina is to collect light that lens has focused on, convert the light into neural signals, and send these signals to your brain for visual …show more content…
Some forms are common to males, some forms are common to females, and some are common to both, male and female. This new study was by researchers led by Daphna Joel. Joel tried to be as comprehensive as possible. Using sets of brain images, the research group measured the volume of gray matter and white matter in the brain of over 1400 people. They also studied data from images of diffusion tensors. The data from diffusion tensor imaging showed how areas of white matter extend throughout the brain, connecting different regions of the brain. The research group found few differences between the male and female brain structure. In the end Joel says, “There is no one type of male brain or female brain.” Between 23% and 53% had a mix of regions that fell on their category (male end of the spectrum and female end of the spectrum). “There is no one person that has all the male characteristics and another person that has all the female characteristics. Or if they existed there really, really rare to find,” Joel claims. So from this study I have learned that the 2 genders, male and female, have brains very much alike. Which leads me to thinking, it may not be the brain, making the different
