That was until February 28th‚ 1953 when scientists James Watson‚ Francis Crick‚ Rosalind Franklin‚ Raymond Gosling‚ and Maurice Wilkins made breakthroughs in the discovery the double helix structure of DNA. The story of their fame and success is portrayed in the movie The Race for the Double Helix. In this film‚ the scientists use two different techniques in their research of DNA. In the end‚ the double helix is discovered when Watson and Crick read a thesis that was written by Franklin. The thesis

The Effects of the Little Albert Studies on Classical Conditioning Classical conditioning has been impacted by many studies. The Little Albert experiment which was done by Watson and Rayner in 1920 showed empirical evidence of classical conditioning in humans. Although this case study is widely disputed in it’s methods‚ it added a world of knowledge to the field of psychology. This was a huge breakthrough for behavioral studies. Up until this time it was shown that classical conditioning was possible

Austin Wilmot Biotechnology Russo 4/21/13 There were many pieces of evidence that led Watson and Crick to their discovery of the structure of DNA. This included Chargaff’s rules‚ X-ray diffraction studies‚ and the use of brass and wire models of sugars‚ and phosphate groups. This revelation contributed heavily to scientific research and studies. They deduced that from their studies that DNA is structured in a Double Helix. With all of the evidence they accumulated they were able to achieve

A more formal recap is as follows: In an effort to demonstrate whether or not emotional responses could be conditioned‚ Watson introduced a baby Albert (nine months) to various stimuli such as a white rat‚ a rabbit‚ dog‚ monkey and various textiles. The “training” involved having an assistant make a loud noise out of Albert’s view and then Watson would record his reaction. When Albert just had the objects‚ he was a very

Piaget’s focus was on the intellectual or cognitive development of children and on the way in which their mind’s processed and progressed in knowledge. Piaget’s central thesis was that children develop self-centric theories about their environment‚ and about objects or persons in that environment‚ and they grow that children base these theories on their
