Define,describe and give examples of classical and operant conditioning - Essay Example If the neutral and unconditioned stimuli are repeatedly paired together, according to the classical conditioning model, the association will produce a behavioral response, which is the â€Å"conditioned response†. Classical conditioning supports the idea that organisms develop responses to particular stimuli that are not naturally occurring but instead generalized from one stimulus onto a neutral stimulus that is paired with it. For instance, in the case of Pavlov’s dog, the meat powder was good, the experimenter was associated with the meat powder, and therefore, the experimenter was associated with good. This syllogistic relationship is a natural and very powerful concept. When Pavlov began pairing a bell sound with the meat powder, he discovered that even when the meat powder did not come, the dogs still responded with salivation. This finding indicated that the dogs prepared for food, even though there was no actual food being presented to them. Operant conditioning is different because it describes a situation in which an individual modifies the content of its behaviors due to an association of that behavior with a stimulus. The classic example involves placing a cat in a box with only one way out.

Communicable Diseases for District of Columbia, Maryland, and Virginia Assignment

Communicable Diseases for District of Columbia, Maryland, and Virginia - Assignment Example Health officials moved with speed to intervene such that by 16th November, the number of deaths significantly dropped to 5,000. The epidemic was one of the worst in the American history. The influenza had a high virulence hence not easy to contain. The influenza is believed to have been transmitted by sailors in Norfolk (Dinh et al., 2006). About 200,000 people were reportedly infected within the first month of the outbreak. The District of Columbia was hit by the dengue fever epidemic in late September, 2010. By October 1st, 160 cases had been reported. The dengue fever spread exponentially such that by October 8th, about 2000 people had been infected with the flu. 450 victims of dengue fever were reported by mid October (Modis et al., 2004). By the third week of October, 750 people had been infected with the virus. The dengue fever was feared to become a pandemic in the rural areas and along the border. It took the intervention of the health and State authorities in Columbia to warn the people about the high prevalence of the fever along the borders since the disease is mostly transmitted through water and humidity (Gubler, 2002). To effectively contain the disease, there was need for the government of Columbia to work hand in hand with the authorities in regions neighboring Columbia. There was an Ebola outbreak in Reston, Virginia in 1989. An outbreak spread relatively fast; however it was nonlethal to humans. Several lab monkeys died, though. Many people tested positive. It was a unique Ebola outbreak in the U.S. history. Although the Ebola virus could only kill monkeys, it was a major health scare (Geisbert et al., 1992). Fortunately, the U.S. authorities were able to move with speed to contain the Reston virus. Patients exposed to the virus never really got sick. Many Americans viewed the Reston crisis as a health horror. Health officials who tried to contain the situation were exposed to the virus, albeit
