In this fun optical illusion, you can see how your visual system and  brain  are actually able to briefly create a color image from a negative photo. How to Perform the Illusion Stare at the dots located at the center of the womans face for about 30 seconds to a minute.Then turn your eyes immediately to the center x of the white image on the right of the womans face.Blink quickly several times. What do you see? If youve followed the directions correctly, you should see an image of a woman in full-color. If you are having trouble seeing the effect, try staring at the negative image a bit longer or adjusting how far you are sitting from your computer monitor. Explanations How does this fascinating visual illusion work? What you are experiencing is known as a negative  afterimage. This happens when the photoreceptors, primarily the cone cells, in your eyes become overstimulated and fatigued causing them to lose sensitivity. In normal everyday life, you dont notice this because tiny movements of your eyes keep the cone cells located at the back of your eyes from becoming overstimulated. Why Do People Experience Afterimages as an Optical Illusion? If, however, you look at a large image, the tiny movements in your eyes arent enough to reduce overstimulation. As a result, you experience what is known as a negative afterimage. As you shift your eyes to the white side of the image, the overstimulated cells continue to send out only a weak signal, so the affected colors remain muted. However, the surrounding photoreceptors are still fresh and so they send out strong signals that are the same as if we were looking at the opposite colors. The brain then interprets these signals as the opposite colors, essentially creating a full-color image from a negative photo. According to the  opponent process theory of color vision, our perception of color is controlled by two opposing systems: a magenta-green system and a blue-yellow system. For example, the color red serves as an antagonist to the color green so that when you stare too long at a magenta image you will then see a green afterimage. The magenta color fatigues the magenta photoreceptors so that they produce a weaker signal. Since magentas opposing color is green, we then interpret the afterimage as green.

The Effects Of Post Traumatic Stress Disorder - 1600 Words

In recent years there has been much dispute over the effects of Post-Traumatic Stress Disorder, or PTSD, on the armed forces. Post-Traumatic Stress Disorder is a medical condition that affects the physiology of the brain. It commonly affects those who have experienced or witnessed stressful events, such as war. PTSD was generally referred to as â€Å"shell-shock† in the military, until an improved and more inclusive definition of the disease was discovered. Wartime environments contain a multitude of factors which are all potential causes of PTSD such as duress accredited to resounding explosions, pressure to survive, being far from home, and moral injury. Even though PTSD manifests itself so frequently in soldiers, there is little care provided for treatment of PTSD. This is a dangerous issue considering the close link between PTSD, suicide, and depression. Readily available, empathetic, and compassionate health care is a necessity for combatting this illness. Soldiers fight to protect the lives of American citizens, and deserve to be protected by those for whom they fought. The military should provide more funding, and better, more available health care for their soldiers because of the rise of Post-Traumatic Stress Disorder in the armed services and the unfavorable effects it has on the armed services.

Night by elie weisel essays

Night by elie weisel essays The novel Night, by Elie Weisel, is a emotional-filled volume of a first person account of the horrors and unthinkable cruelty dealt to a innocent child during the holocaust. Critics throughout the world raved at this literary masterpiece calling it A Slim Volume Of Terrifying Power# and exclaiming To the best of my knowledge no one has left behind him so moving a record.# This truly horrific account is a must read for any young adult, and should be put onto reading lists worldwide indefinitely. This novel uses many accounts of symbolism to paint a vivid picture of death and to set a dreary atmosphere. Cold images of people being brutally beaten, towering chimneys used to burn family and friends symbolizing death and suffering, German SS officers symbolizing fear to all that succumbs to them. Right next to us the high chimney of the crematory oven rose up. It no longer made any impression on us. It scarcely attracted our attention, this line symbolizes the loss of hope and extremely low moral these refugees became to know as life. This book was written in a very descriptive style, taking full advantage of his first-person experience to write with gruesome detail. The writer uses descriptive sentences to immerse the reader in the experience. Another key aspect of technique in his writing is his use of rhetorical questions. Where is the divine mercy? Where is god? How can I believe, how can anyone believe, in this merciful god?, is a line containing three rhetorical questions used to work on a readers emotion. Major characters in the story are Eliser, Moshe the Beadle, and Elisers father. Eliser is the main charactor and author of the book. The novel follows young Eliser through the ups and downs of his visits through the concentration camps. He is a timid young man, not well educated and not emotionally equipped for this journey.

Demographic Trends of Gun Ownership in the U.S.

Demographic Trends of Gun Ownership in the U.S. The perception of who owns guns in the U.S. is heavily shaped by stereotypes perpetuated by news media, film, and television. The armed black man (or boy) is one of the most pervasive images in our media culture, but the image of the armed white southerner, the military veteran, and the hunter are common too. The results of a 2014 Pew Research Center survey revealed that while some of these stereotypes hold true, others are way off the mark, and possibly quite damaging in their mischaracterization. 1 in 3 Americans Live in a Home With Guns Pews survey, which included 3,243 participants from across the country, found that just over a third of all American adults have guns in their homes. The rate of gun ownership is slightly higher for men than for women, and fairly even across the nation, with the exception of the northeast, where just 27 percent have them, as compared with 34 percent in the west, 35 percent in the midwest, and 38 percent in the south.  Pew also found similar rates of ownership among those with children in the home and those without about a third across the board. Thats where the general trends end and significant differences emerge around other variables and characteristics. Some of them may surprise you. Older, Rural, and Republican Americans Are More Likely to Own Guns The study found that gun ownership is highest among those over 50 years of age (40 percent) and lowest among young adults  (26 percent), while ownership among middle-aged adults mimics the overall trend. At 51 percent, gun ownership is far more likely among rural residents than all others and lowest in urban areas (25 percent). Its also far more likely among those who affiliate with the Republican party (49 percent) than among those who are Independents (37 percent) or Democrats (22 percent). Ownership by ideology conservative, moderate, and liberal shows the same distribution. White People Are Twice as Likely to Own Guns Than Blacks and Hispanics The really surprising result given the way violence is present within racial stereotypes has to do with race. White adults are twice as likely to have guns at home than are blacks and Hispanics. While the overall rate of ownership among whites is 41 percent, it is just 19 percent among blacks and 20 percent among Hispanics. In other words, while more than 1 in 3 white adults lives in a house with guns, just 1 in 5 black or Hispanics adults do the same. It is gun ownership among white people, then, that drives the national rate up to 34 percent. However, despite this disparity in ownership by race, blacks and Hispanics are far more likely than whites to be the victims of gun homicide. That rate is highest for Blacks,  which is likely influenced by the over-representation of homicide by police among this racial group, especially since they are the  racial group  least likely to actually own guns. Pews data also reveal a significant trend at the intersection of race and geography: nearly half of all white southerners have guns in the home. (The low rate of ownership among blacks in the south brings the overall rate for the region down by nine percentage points.) Gun Owners Are More Likely to Identify as a Typical American Perhaps most fascinating (and troubling) among the findings is the set of data that show a connection between gun ownership and American values and identity. Those who own guns are more likely than the general population to identify as a typical American,  to claim honor and duty as core values, and to say that they often feel proud to be American. And, while those who own guns are also more likely to consider themselves outdoor people, just 37 percent of gun owners identify as hunters, fishers, or sportsmen. This finding would seem to debunk the common sense notion that people keep firearms for hunting. In fact, most do not actually hunt with them. Pews Findings Raise Questions About Gun Crime in the U.S. For those concerned about the high rate of gun crime in the U.S. compared with other nations, the findings pose some serious questions. Why are police far more likely to kill black men than any others, especially given that most of those killed by police are unarmed? And, what are the public health consequences of the centrality of firearms to American values and identity? Perhaps its time to frame media representation of black men and boys which overwhelmingly portrays them as perpetrators and victims of gun crime as a national public health crisis. Certainly, this pervasive imagery has an effect on the expectation among police that they will be armed, despite the fact that they are the  least  likely racial group to be. Pews data also suggest that tackling gun crime in the U.S. will require the decoupling of American values, traditions, rituals, and identity from firearms, as they seem to be tightly linked for many gun owners. These associations likely fuel the scientifically debunked good guy with a gun thesis that suggests that gun ownership makes society safer. Sadly, a mountain of scientific evidence shows that  it does not, and its important that we understand the cultural underpinnings of gun ownership if we really want to have a safer society.
