The Cannon-Washburn Hunger Experiment was conducted in 1912 by American physiologist Walter Cannon and his colleague, graduate student A.L. Washburn. This experiment investigated the physiological mechanisms of hunger by examining the relationship between stomach contractions and the sensation of hunger.
Walter Cannon began his career in science as a Harvard undergraduate in the year 1892. Henry Pickering Bowditch, who had worked with Claude Bernard, directed the laboratory in physiology at Harvard. Here Cannon began his research: he used the newly discovered x-rays to study the mechanism of swallowing and the motility of the stomach.
Washburn's equation is also used commonly to determine the contact angle of a liquid to a powder using a force tensiometer. [ 5 ] In the case of porous materials, many issues have been raised both about the physical meaning of the calculated pore radius r {\displaystyle r} [ 6 ] and the real possibility to use this equation for the calculation ...
The main concepts of the Cannon–Bard theory are that emotional expression results from the function of hypothalamic structures, and emotional feeling results from stimulations of the dorsal thalamus. The physiological changes and subjective feeling of an emotion in response to a stimulus are separate and independent; arousal does not have to ...
Charles Haldat made some penetrating criticisms of the reproducibility of Rumford's results [15] and it is possible to see the whole experiment as somewhat tendentious. [16] However, the experiment inspired the work of James Prescott Joule in the 1840s. Joule's more exact measurements were pivotal in establishing the kinetic theory at the ...
Sham rage is behavior such as biting, clawing, hissing, arching the back, and "violent alternating limb movements" produced in animal experiments by removing the cerebral cortex, which are claimed to occur in the absence of any sort of inner experience of rage. [1] These behavioral changes are reversed with small lesions in hypothalamus. [2]
Washburn published many of her students' studies during her career. The students would collect and work with the data while she wrote up and published the experiments. Between 1905 and 1938, she published 68 studies from the Vassar Undergraduate Laboratory. These studies were the largest series of studies from any American university at the time.
Robert Sessions Woodworth (October 17, 1869 – July 4, 1962) was an American psychologist and the creator of the personality test which bears his name.A graduate of Harvard and Columbia, he studied under William James along with other prominent psychologists as Leta Stetter Hollingworth, James Rowland Angell, and Edward Thorndike.
