Definition and Examples of Semantic Satiation

Definition and Examples of Semantic Satiation Definition Semantic satiation is a phenomenon whereby the uninterrupted repetition of a word eventually leads to a sense that the word has lost its meaning. This effect is also known as  semantic saturation or verbal satiation. The concept of semantic satiation was described by E. Severance and M.F. Washburn in The American Journal of Psychology in 1907. The term was introduced by psychologists Leon James and Wallace E. Lambert in the article Semantic Satiation Among Bilinguals in the Journal of Experimental Psychology (1961). For most people, the way theyve experience semantic satiation is in a playful context: deliberately repeating a single word over and over again just to get to that sensation when  it stops feeling like an actual word. However, this phenomenon can appear in more subtle ways. For instance, writing teachers will often insist that students use repeated words with care, not just because it demonstrates a better vocabulary  and a more eloquent style,  but to avoid the loss of significance. Overuse of strong words, such as words with intense connotations or profanity, can also fall victim to semantic satiation and lose their intensity.   See Examples and Observations below.

I fell to repeating the word Jersey over and over again, until it became idiotic and meaningless. If you have ever lain awake at night and repeated one word over and over, thousands and millions and hundreds of thousands of millions of times, you know the disturbing mental state you can get into.(James Thurber, My Life and Hard Times, 1933)Have you ever tried the experiment of saying some plain word, such as dog, thirty times? By the thirtieth time it has become a word like snark or pobble. It does not become tame, it becomes wild, by repetition.(G.K. Chesterton, The Telegraph Poles. Alarms and Discursions, 1910)A Closed LoopIf we pronounce a word over and over again, rapidly and without pause, then the word is felt to lose meaning. Take any word, say, CHIMNEY. Say it repeatedly and in rapid succession. Within some seconds, th e word loses meaning. This loss is referred to as semantic satiation. What seems to happen is that the word forms a kind of closed loop with itself. One utterance leads into a second utterance of the same word, this leads into a third, and so on. . . . [A]fter repeated pronunciation, this meaningful continuation of the word is blocked since, now, the word leads only to its own recurrence.(I.M.L. Hunter, Memory, rev. ed. Penguin, 1964) The MetaphorSemantic satiation is a metaphor of sorts, of course, as if neurons are little creatures to be filled up with the word until their little bellies are full, they are sated and want no more. Even single neurons habituate; that is, they stop firing to a repetitive pattern of stimulation. But semantic satiation affects our conscious experience, not just individual neurons.(Bernard J. Baars, In the Theater of Consciousness: The Workspace of the Mind. Oxford University Press, 1997)Disconnection of Signifier and Signified- If you stare continuously at a word (alternatively, listen to it over and over), the signifier and signified eventually appear to fall apart. The aim of the exercise is not to alter vision or hearing but to disrupt the internal organization of the sign. . . . You continue to see the letters but they no longer make the word; it, as such, has vanished. The phenomenon is called semantic satiation (first identified by Severance Washburn 1907), or loss of the sign ified concept from the signifier (visual or acoustic).(David McNeill, Gesture and Thought. University of Chicago Press, 2005)- [B]y saying a word, even a significant one, over and over again . . . you will find that the word has been transformed into a meaningless sound, as repetition drains it of its symbolic value. Any male who has served in, let us say, the United States Army or spent time in a college dormitory has had this experience with what are called obscene words . . .. Words that you have been taught not to use and that normally evoke an embarrassed or disconcerted response, when used too often, are stripped of their power to shock, to embarrass, to call attention to a special frame of mind. They become only sounds, not symbols.(Neil Postman, Technopoly: The Surrender of Culture to Technology. Alfred A. Knopf, 1992) OrphanWhy has my fathers death left me feeling so alone, when he hasnt been a part of my life in seventeen years? Im an orphan. I repeat the word out loud, over and over again, listening to it bounce off the walls of my childhood bedroom until it makes no sense.Loneliness is the theme, and I play it like a symphony, in endless variations.(Jonathan Tropper, The Book of Joe. Random House, 2004)Boswell on the Effects of Intense Inquiry (1782)Words, the representations, or rather signs of ideas and notions in the human race, though habitual to all of us, are, when abstractly considered, exceedingly wonderful; in so much, that by endeavouring to think of them with a spirit of intense inquiry, I have been affected even with giddiness and a kind of stupor, the consequence of having ones faculties stretched in vain. I suppose this has been experienced by many of my readers, who in a fit of musing, have tried to trace the connection between a word of ordinary use and its meaning, repeating th e word over and over again, and still starting in a kind of foolish amazement, as if listening for information from some secret power in the mind itself.(James Boswell [The Hypochondriack], On Words. The London Magazine, or, Gentlemans Monthly Intelligencer, Volume 51, February 1782)

Element Abundance of the Universe

Element Abundance of the Universe The element composition of the universe is calculated by analyzing the light that is emitted and absorbed from stars, interstellar clouds, quasars,  and other objects. The Hubble telescope greatly expanded our understanding of the composition of galaxies and gas in the intergalactic space between them. About 75% of the universe is believed to consist of dark energy and dark matter, which are different from the atoms and molecules that make up the everyday world around us. Thus, the composition of most of the universe is far from understood. However, spectral measurements of stars, dust clouds, and galaxies tell us the elemental composition of the portion that consists of normal matter. Most Abundant Elements in the Milky Way Galaxy This is a table of elements in the Milky Way, which is similar in composition to other galaxies in the universe. Keep in mind, elements represent matter as we understand it. Much more of the galaxy consists of something else! Element Element Number Mass Fraction (ppm) hydrogen 1 739,000 helium 2 240,000 oxygen 8 10,400 carbon 6 4,600 neon 10 1,340 iron 26 1,090 nitrogen 7 960 silicon 14 650 magnesium 12 580 sulfur 16 440    Most Abundant Element in the Universe Right now, the most abundant element in the universe is hydrogen. In stars, hydrogen fuses into helium. Eventually, massive stars (around 8 times more massive than our Sun) run through their supply of hydrogen. Then, the core of helium contracts, supplying enough pressure to fuse two helium nuclei into carbon. Carbon fuses into oxygen, which fuses into silicon and sulfur. Silicon fuses into iron. The star runs out of fuel and goes supernova, releasing these elements back into space. So, if helium fuses into carbon you may be wondering why oxygen is the third most abundant element and not carbon. The answer is because the stars in the universe today are not first generation stars! When newer stars form, they already contain more than just hydrogen. This time around, stars fuse hydrogen according to whats known as the C-N-O cycle (where C is carbon, N is nitrogen, and O is oxygen). A carbon and helium can fuse together to form oxygen. This happens not just in massive stars, but also in stars like the Sun once it enters its red giant phase. Carbon really comes out behind when a type II supernova occurs, because these stars undergo carbon fusion into oxygen with almost perfect completion! How Element Abundance Will Change in the Universe We wont be around to see it, but when the universe is thousands or millions times older than it is now, helium may overtake hydrogen as the most abundant element (or not, if enough hydrogen remains out in space to far from other atoms to fuse). After a much longer time, its possible oxygen and carbon may become the first and second most abundant elements! Composition of the Universe So, if ordinary elemental matter doesnt account for most of the universe, what does its composition look like? Scientists debate this subject and revise percentages when new data becomes available. For now, the matter and energy composition is believed to be: 73% Dark Energy: Most of universe seems to consist of something we know next to nothing about. Dark energy probably doesnt have mass, yet matter and energy are related.22% Dark Matter: Dark matter is stuff that doesnt emit radiation in any wavelength of the spectrum. Scientists are unsure what, exactly, dark matter is. It has not be observed or created in a lab. Right now, the best bet is that its cold dark matter, a substance consisting of particles comparable to neutrinos, yet much more massive.4% Gas: Most of the gas in the universe is hydrogen and helium, found between stars (interstellar gas). Ordinary gas does not emit light, although it does scatter it. Ionized gases glow, but not brightly enough to compete with the light of stars. Astronomers use infrared, x-ray, and radio telescopes to image this matter.0.04% Stars: To human eyes, it appears the universe is full of stars. Its amazing to realize they account for such a small percentage of our reality.0.3% Neutrinos: Neutrinos are tiny, electrically neutral particles that travel at near light speed. 0.03% Heavy Elements: Only a tiny fraction of the universe consists of elements heavier than hydrogen and helium. Over time this percentage will grow.
