(JEFFREY MOUSSAIEFF MASSON & SUSAN MCCARTHY‚ When Elephants Weep) Now a days is common to listen that more and more kind of animals are going to be part of a long list of species in extinction called “the red list”‚ When a animal is endangered it means that they are disappearing fast or have a very small population. Every day we can see in the media the great campaign that is carried out to preserve these animals‚ as for example: they

Spontaneous Recovery and Extinction Spontaneous recovery from extinction is one of the most basic phenomena of Pavlovian conditioning. Although it can be studied by using a variety of designs‚ some procedures are better than others for identifying the involvement of underlying learning processes. A wide range of different learning mechanisms has been suggested as being engaged by extinction‚ most of which have implications for the nature of spontaneous recovery. However‚ despite

Let A be the event that the student passes the first test and B be the event that he passes the second. Suppose that : P(A) = 0.6 P(B) = 0.8 P(A ∩ B) = 0.5 a.

Carl Zimmer discusses the idea of bringing back a species from extinction throughout his essay. With examples such as the Pyrenean ibex‚ mammoths‚ passenger pigeons‚ and gastric brooding frogs‚ he discusses how technology and science have advanced to the point that de-extinction is close to being a reality. Zimmer then shifts to the benefits and problems that could arise if we are able to revive an extinct species. As a result‚ Zimmer raises the question that should we bring back an extinct species

The Destruction of Biodiversity Why should you care? You should care‚ because there exists a chain to which all life is linked. Humans stand not apart‚ and there is no beginning or end. Extinction is like a trickling stream that grows to threaten riverbanks before drowning the world with oceans. We are foolish and naïve to assume that our creek can be maintained as we constantly introduce new species into foreign ecosystems‚ and destroy biodiversity with the detrimental effects of human integration

What do you think are the differences and similarities between Classical conditioning and Operant conditioning? Many people believe that Classical and Operant are similar. Several people don’t know what the similarities and differences of Classical and Operant are‚ several people think it is the same learning method‚ which in this case I’m going to compare and contrast each behavior and give you information about each one‚ so you could have a better understanding of each method and what they do.
