Wilhelm Wundt's Psychology: Judgment - Wilhelm Wundt's Psychology: Judgment It is almost impossible to write historically informed essays about any given topic in modern psychology without making reference to the work of Wilhelm Wundt. In part, this is because he produced a tremendous amount of written work (over 53,735 published pages1), and because he is widely regarded as the first experimental psychologist.2 So, it’s no surprise that Wundt has something to say about the psychology of judgment. Given the historical context in which his work took place, however, you might be surprised to learn that Wundt was keenly aware of both the problems with traditional associationist accounts of psychology and the temptations of psycholo...   [tags: Wilhelm Wundt Psychology Essays]

Critique on Gottfried Wilhelm von Leibniz's Theories on the Mind - Gottfried Wilhelm von Leibniz has the view that the mind of a substance, including humans, is not a composite entity. To Leibniz, the mind is similar to a mill, in the sense that it is like a machine where all of the parts of it work together. When, in reality, the mind is something that is complex, and needs both an intellectual and a technical side to it for it to function –quite unlike the machine Leibniz claims it is. His argument, known as “The Mill Argument”, states that if a person were to walk into a mill, he or she would observe the inner workings of it, and not know what the parts are made of, or how they are related....   [tags: mind, thinking]

The ROAD to Success - The R.O.A.D. to Success Today in America, one prominent field is always in need of new workers: the medical field. The demand for physicians has steadily increased over the past few decades. Logically, this makes sense considering that the United States’ population has increased by nearly 70 million people in a span of 30 years (“Population”). Patients are limited to the doctors that are employed within a convenient distance; with a limited number of doctors being put out every year (approximately 25,000), hospitals are providing more with less (Cauchon)....   [tags: Medical Field]

The History of Chemistry - ... In 1774-1794, Joseph Priestley discovered a colorless gas he called “dephlogisticated air”, which is actually oxygen, by taking a calx of mercury and burning it. Antoine Lavoisier disapproved the Phlogiston Theory. He named the “dephlogisticated air” oxygen when he realized oxygen combines with substances as the burn. Lavoisier is now called the “Father of Modern Chemistry” because of his attributions.

Radiation and Its Uses, Specifically in South Africa - What is radiation. Radiation is energy that comes from a source and travels in the form of waves or high speed particles. Radiation is mainly released from atoms, which is the smallest particle of matter. When radiation is emitted, it excites the orbiting electrons in atoms and causes the electrons to vibrate, which emits the energy. There are two types of radiation, namely Ionizing radiation and non-ionizing radiation. Non- ionizing radiation has a low energy level and therefore cannot change the chemical properties of a substance that it is exposed to....   [tags: Ionization, Energy, Cancer] 1923 words
