through the pupils of my eyes. My pupils widened and narrowed to control the amount of light that was brought Into my eyes. This light then went through the pupil and also the vitreous humor, a clear and Jelly-Like substance Inside of the eyeball.

The light struck the retina. Because it was not too dark or dim outside, the cones of the retina were mainly activated, but rods were also activated.

The cornea and lens focused and fine-tuned the light on the retina in order to focus the distances of the objects in my sight, as well as other factors. Because the person I was preparing myself to speak with was within a close distance to where I as standing, my lens became thicker and more round and my eye muscles tightened.

Then, ganglion cells, which get their information from bipolar cells, use their axons in the retina to gather information, which leaves the eye from the blind spot, which is the area where the optic nerves goes away from the retina. The data travels through the optic schism and on to the visual cortex, in the occipital lobe of the brain, which is pinpointed as the lobe in the back of the brain.

From the visual cortex, the Information will be coded to process the person whom I was going to meet ere quickly, as well as all of the other details of her, and the background to where we were.

However, the occipital lobe is not the only part of the brain that is stimulated. Though seemingly unusual, the temporal lobe is also roused. In James W.

Slat's, Introduction to Psychology Koala states

that the temporal lobe "... Is the main area for hearing and some of the complex aspects of vision.

.. One area... Responds only to the sight of faces" (Koala 2008, peg.

81). So, I talk with this stranger, and find out that she, rather, from Thailand. Filled with inquiries, I move to shake hands with my new friend.

As I see her bring her hands up from her sides, my perception is challenged.

Perception is defined as "the interpretation of that information" (Koala 2008, peg. 97). "That information" refers to the material gathered in sensation. When my friend swings her hands from their resting place, I recognize that her hand does not actually get physically larger, and I exhibit size constancy, which is the inclination to see objects as keeping their size, though there are certain alterations in the light tatters that reach my retinas.

Depth perception is also demonstrated when, unconsciously, my eyes come together a specific distance, and turn in at a particular angle to focus on the "close object" (essentially, my new friend. ) My eyes will not be completely parallel, because my acquaintance is at a close distance to me, and the muscles in my eye pull from tension to focus on an object that is close to me.

I held conversation with my friend, and bonded over Asian food, the excitement of being at college, and all of the fascinating opportunities that lay ahead for the both of us at Berkeley.

In the end, it turned out that she and I both lived on the same floor in the same building. After exchanging numbers and promises to see each other

the next day for lunch, we both turned to meet and greet others around us. As she walked away from where I was standing, perception once again played a large role, as size constancy ensured that I knew that my first friend in college was not actually shrinking in size, but was merely Just walking further and further away from me.
