Do Boys and Girls See Optical Illusions Differently?

The goal of this paper is to focus on how gender affects what people see in optical illusions. The differences of male and female brains affect how boys and girls act and perceive the world. If there’s a difference in the vision of boys and girls then there will probably be a difference in how they see an optical illusion. Studies show that there are multiple differences in the male and female brain. There are different types of optical illusions, but this paper is mainly about ambiguous illusions because that is what will be used in the experiment. Ambiguous illusions are pictures with multiple images in them. Evidence

Though there are many differences in the male and female brain, there are little differences that may affect vision. Our eyes are set up a lot like a camera. The pupil is an opening where light enters the eye. The pupil has two curved, transparent structures; the cornea and the lens. They control the path taken by lights and create, on the back of the eye, an inverted image of what is being observed. This image falls on the retina, a sheet of neurons in the back of the eye. The retina transforms the three dimensional world into a pattern of activity in a two dimensional sheet of neurons. While it does this, it throws away a lot of information and leaves the brain to fill in additional information in its own way. The retinal neurons are a sheet of pixels that detect the intensity of light. Three different types of cone cells in the retina detect red, green, and blue in bright light. Other colors are formed by different levels of activity on combinations of three cell types. Rods detect light intensity in dim light, but do not contribute to color vision. Rods and cones communicate with other neurons. The retina also includes a layer of photoreceptors. Photoreceptors are neurons that measure light intensity and translate into a signal which the nervous system can understand. Each photoreceptor generates a signal related to the intensity of the light coming from a corresponding point of the observed object. Signals from light falling on
