Milgram experiment The experimenter (E) orders the teacher (T), the subject of the experiment, to give what the latter believes are painful electric shocks to a learner (L), who is actually an actor and confederate. The subject believes that for each wrong answer, the learner was receiving actual electric shocks, though in reality there were no such punishments. Being separated from the subject, the confederate set up a tape recorder integrated with the electro-shock generator, which played pre-recorded sounds for each shock level.[1] The experiments began in July 1961, three months after the start of the trial of German Nazi war criminal Adolf Eichmann in Jerusalem. Milgram devised his psychological study to answer the popular question at that particular time: "Could it be that Eichmann and his million accomplices in the Holocaust were just following orders? The experiment[edit] Milgram Experiment advertisement The subjects believed that for each wrong answer, the learner was receiving actual shocks.
Donner Party 19th-century group of American emigrants who became trapped in the Sierra Nevada mountains The Donner Party, sometimes called the Donner–Reed Party, were a group of American pioneers who migrated to California in a wagon train from the Midwest. Delayed by a multitude of mishaps, they spent the winter of 1846–1847 snowbound in the Sierra Nevada mountain range. Some of the migrants resorted to cannibalism to survive, primarily eating the bodies of those who had succumbed to starvation, sickness or extreme cold, but in one case two Native American guides were deliberately killed for this purpose.[1] The Donner Party originated from Springfield, Illinois, and departed Independence, Missouri, on the Oregon Trail in the spring of 1846, behind many other pioneer families who were attempting to make the same overland trip. By early November, the migrants had reached the Sierra Nevada but became trapped by an early, heavy snowfall near Truckee Lake (now Donner Lake) high in the mountains.
Semantic satiation History and research[edit] The phrase "semantic satiation" was coined by Leon Jakobovits James in his doctoral dissertation at McGill University, Montreal, Canada awarded in 1962.[1] Prior to that, the expression "verbal satiation" had been used along with terms that express the idea of mental fatigue. The dissertation listed many of the names others had used for the phenomenon: "Many other names have been used for what appears to be essentially the same process: inhibition (Herbert, 1824, in Boring, 1950), refractory phase and mental fatigue (Dodge, 1917; 1926a), lapse of meaning (Bassett and Warne, 1919), work decrement (Robinson and Bills, 1926), cortical inhibition (Pavlov, 192?), adaptation (Gibson, 1937), extinction (Hilgard and Marquis, 1940), satiation (Kohler and Wallach, 1940), reactive inhibition (Hull, 1913 [sic]), stimulus satiation (Glanzer, 1953), reminiscence (Eysenck, 1956), verbal satiation (Smith and Raygor, 1956), and verbal transformation (Warren, 1961b)."

Black Death Spread of the Black Death in Europe (1346–53) The Black Death is thought to have originated in the arid plains of central Asia, where it then travelled along the Silk Road, reaching the Crimea by 1343.[6] From there, it was most likely carried by Oriental rat fleas living on the black rats that were regular passengers on merchant ships. Spreading throughout the Mediterranean and Europe, the Black Death is estimated to have killed 30–60% of Europe's total population.[7] In total, the plague reduced the world population from an estimated 450 million down to 350–375 million in the 14th century. The aftermath of the plague created a series of religious, social, and economic upheavals, which had profound effects on the course of European history. It took 150 years for Europe's population to recover.[citation needed] The plague recurred occasionally in Europe until the 19th century. Chronology Origins of the disease European outbreak There appear to have been several introductions into Europe.
Pareidolia A satellite photo of a mesa in Cydonia, often called the Face on Mars. Later imagery from other angles did not contain the illusion. Examples[edit] Projective tests[edit] The Rorschach inkblot test uses pareidolia in an attempt to gain insight into a person's mental state. Art[edit] In his notebooks, Leonardo da Vinci wrote of pareidolia as a device for painters, writing "if you look at any walls spotted with various stains or with a mixture of different kinds of stones, if you are about to invent some scene you will be able to see in it a resemblance to various different landscapes adorned with mountains, rivers, rocks, trees, plains, wide valleys, and various groups of hills. Religious[edit] Publicity surrounding sightings of religious figures and other surprising images in ordinary objects has spawned a market for such items on online auctions like eBay. Divination[edit] Various European ancient divination practices involve the interpretation of shadows cast by objects. Fossils[edit]
Andrée's Arctic balloon expedition Failed attempt to reach the North Pole by balloon Andrée's Arctic balloon expedition of 1897 was an effort to reach the North Pole in which all three Swedish expedition members – S. A. Andrée, Knut Frænkel, and Nils Strindberg – perished. Andrée, the first Swedish balloonist, proposed a voyage by hydrogen balloon from Svalbard to either Russia or Canada, which was to pass, with luck, straight over the North Pole on the way. The scheme was received with patriotic enthusiasm in Sweden, a northern nation that had fallen behind in the race for the North Pole. Andrée ignored many early signs of the dangers associated with his balloon plan. After Andrée, Strindberg, and Frænkel lifted off from Svalbard in July 1897, the balloon lost hydrogen quickly and crashed on the pack ice after only two days.

Sense of agency The "sense of agency" (SA) refers to the subjective awareness that one is initiating, executing, and controlling one's own volitional actions in the world.[1] It is the pre-reflective awareness or implicit sense that it is I who is executing bodily movement(s) or thinking thoughts. In normal, non-pathological experience, the SA is tightly integrated with one's "sense of ownership" (SO), which is the pre-reflective awareness or implicit sense that one is the owner of an action, movement or thought. If someone else were to move your arm (while you remained passive) you would certainly have sensed that it were your arm that moved and thus a sense of ownership (SO) for that movement. However, you would not have felt that you were the author of the movement; you would not have a sense of agency (SA).[2] Definition[edit] Neuroscience of the sense of agency[edit] Agency and psychopathology[edit] Marc Jeannerod proposed that the process of self-recognition operates covertly and effortlessly.
Bubbly Creek Bubbly Creek originates near 38th Street, at the Racine Avenue Pump Station of the Metropolitan Water Reclamation District of Greater Chicago. It flows in a generally northward direction for approximately 6,600 feet (2,000 m), and joins with the South Branch of the Chicago River.[2] History[edit] A man standing on slaughterhouse-derived waste in Bubbly Creek in Chicago in 1911. The area surrounding Bubbly Creek was originally a wetland; during the 19th century, channels were dredged to increase the rate of flow into the Chicago River and dry out the area to increase the amount of habitable land in the fast-growing city. The South Fork became an open sewer for the local stockyards, especially the Union Stock Yards. In 1906, author Upton Sinclair wrote The Jungle, an unflattering portrait of America's meat packing industry. Present situation[edit] Bubbly Creek and Bridgeport Village Some fish and vegetation have returned in recent decades.[4] References[edit] External links[edit]
