Effect of Face Blindness on Emotions
Face Blindness Affects Emotions
It is common for face blind people to say their emotional life is different than that of most people. For some this difference is slight, but others have gone so far as to say they felt they were more "emotion blind" than face blind, and that their emotion blindness affected their life more than their face blindness. To help in understanding why this occurs, we'll first look at how emotions work in most people, and then we'll consider how it may be different in face blind people.
A Look at Emotions
Emotions are how we feel - things like happiness, sadness, anger, and fear. We have feelings ourselves, and so do other people. We communicate those feelings to others. And some of our greatest joys come from feeling the emotions of others. It is possible to have a neurological deficiency that prevents one from having normal emotions. Since the presence of one neurological problem such as face blindness sometimes indicates others are present, too, a face blind person having difficulties with emotions must not rule such a deficiency out. However, many face blind people do not have such, and thus, it is beyond the scope of this discussion to delve into details about that. I would feel remiss to not mention having such a deficiency as a possibility, though, that one with face blindness must consider. A person with normal emotional capabilities can still have difficulties if he is unable to receive and send emotional information during his encounters with people. As we shall see, face blindness can interfere with one's

On the right you see a rotating array of blue crosses and 3 yellow dots. Now fixate the centre (watch the flashing green spot). Note that the yellow spots disappear once in a while: singly, in pairs or all three simultaneously. In reality, the 3 yellow spots are continuously present, honest! You can click on the ←/→ buttons to change speed. Disappearence persists down to surprisingly low speeds. Comment Steady fixation favours disappearance, blinks or gaze shifts induce reappearance. All in all reminiscent of the Troxler effect, but stronger and more resistant against residual eye movements.

Study: Vitamins combat age-related blindness
Story Tools HEALTH LIBRARY Health Library YOUR E-MAIL ALERTS Macular degeneration Blindness Vitamins or Create your own Manage alerts What is this? CHICAGO, Illinois (Reuters) Hundreds of thousands of people could benefit from vitamin supplements shown to help prevent macular degeneration, a condition that is the leading cause of blindness from age 65, a study reported. In 2001, researchers announced they had found a reduced risk of advanced age-related macular degeneration and vision loss for test subjects who had been given high-dose antioxidant supplements vitamins C, E and beta carotene as well as zinc or zinc oxide. In Monday's report, researchers at the Johns Hopkins Medical Institutions in Baltimore tried to estimate how many people in the United States alone would benefit from increasing supplement use. They concluded there are 8 million Americans at least 55 years old thought to be at high risk for the problem. If all the people at risk took the supplements used in the earlier study, more than 300,000 of them would avoid advanced macular degeneration and any associated vision loss during the next five years, the study said.

blindness. From Wikipedia, the free encyclopedia. blindness can be defined Causes of blindness. Diseases of the eye. The most common causes
From Wikipedia, the free encyclopedia.
Blindness can be defined physiologically as the condition of lacking sight . The definition as it applies to people thus legally classified is, however, more complex. In North American and most of Europe, legal blindness is defined as vision of 20/200 (6/60) or less in the better eye with correction. People with normal acuity who nonetheless have a visual field of less than 20 degrees - the norm being 180 degrees - are also classified as being legally blind The World Health Organization defines legal blindness as vision of 20/400 (3/60) or less in the better eye with correction. They also accept people with a visual field of less than 10 degrees under that heading. Approximately ten percent of those classified as being legally blind are actually sightless. The rest have some vision, from light perception alone to relatively good acuity. Table of contents 1 Low vision 2 Causes of blindness 2.1 Diseases of the eye

Many countries also have a legal provision for people who, though not legally blind, have vision poor enough to affect their performance of daily tasks using traditional methods.

52. Vision Impairment (part 1), NCBDDD, CDC
blindness is defined as a visual acuity worse than 20/400, with the best possible correction, or a visual field of 10 degrees or less.
NCBDDD Home Vision Impairment What Is Vision Impairment? How Common Is It? ... Click here to contact the National Center on Birth Defects and Developmental Disabilities. What is vision impairment? Vision impairment means that a person's eyesight cannot be corrected to a "normal" level. It is a loss of vision that makes it hard or impossible to do daily tasks without specialized adaptations. Vision impairment may be caused by a loss of visual acuity, where the eye does not see objects as clearly as usual. It may also be caused by a loss of visual field, where the eye cannot see as wide an area as usual without moving the eyes or turning the head. There are different ways of describing how severe a person's vision loss is. The World Health Organization defines "low vision" as visual acuity between 20/70 and 20/400, with the best possible correction, or a visual field of 20 degrees or less. "Blindness" is defined as a visual acuity worse than 20/400, with the best possible correction, or a visual field of 10 degrees or less. Someone with a visual acuity of 20/70 can see at 20 feet what someone with normal sight can see at 70 feet. Someone with a visual acuity of 20/400 can see at 20 feet what someone with normal sight can see at 400 feet. A normal visual field is about 160-170 degrees horizontally. Vision impairment severity may be categorized differently for certain purposes. In the United States, for example, we use the term "legal blindness" to indicate that a person is eligible for certain education or federal programs. Legal blindness is defined as a visual acuity of 20/200 or worse, with the best possible correction, or a visual field of 20 degrees or less.

53. Conditioned Ethical Blindness
Excerpted from Lori Gruen and Peter Singer, 'Animal Liberation A Graphic Guide' (London, 1987).
Conditioned Ethical Blindness By Lori Gruen and Peter Singer Excerpted from Animal Liberation: a Graphic Guide , London, 1987, pp. 78-80 ANIMAL LIBERATION A Graphic Guide by Lori Gruen and Peter Singer other books How can otherwise decent citizens do these things? How can they become so insensitive to what they are doing? Don Barnes, who spent sixteen years as a biomedical scientist experimenting on animals, and now heads the Washington, DC office of the National Anti-Vivisection Society , calls the state in which he used to do his work 'conditioned ethical blindness'. From his early years growing up on the farm, and continuing into his time as a Ph. D. student, Barnes accepted the idea that non-human animals exist to serve human purposes. As a student of psychology, he was also taught a whole new vocabulary which served to distance the experimenter from the animal. The monkeys on which he worked became 'research subjects'; the electric shocks he gave them were called 'negative reinforcement' and their vain efforts to escape were classified as 'avoidance behaviour'. As Barnes says: 'During my sixteen years in the laboratory the morality and ethics of using laboratory animals were never broached in either formal or informal meetings prior to my raising the issues during the waning days of my tenure as a vivisector'. Don Barnes is not the only one to have escaped his conditioning. In 1977 the magazine

, but it affects only .4 percent of women. The fact that color blindness is so much more prevalent among men implies that, like hemophilia, it is carried on the X chromosome, of which men have only one copy. (As in hemophilia, women are protected because they have two X chromosomes; a normal gene on one chromosome can often make up for a defective gene on the other.) Nathans himself is not color-blind. Before using his own DNA, he thoroughly tested his color vision to ensure that it was normal. Nevertheless, one of his initial findings presented a puzzle: Lying head to tail along his X chromosome were not just the two genes for the red and green receptors, but also an extra copy of the green receptor gene. Here was the explanation for the prevalence of color blindness, he realized. Because the DNA sequences of the red and green receptor genes are so similar, and because they lie head to tail, it is easy for mistakes to occur during the development of egg and sperm, as genetic material is replicated and exchanged between chromosomes.
