These A-B intermediate forms adopt the sugar pucker properties and/or the base conformation of both DNA forms. In one study, the characteristic C3'-endo pucker is found on the first three sugars of the DNA strand, while the last three sugars have a C2'-endo pucker, like B-DNA. [ 2 ]
The Stanford marshmallow experiment was a study on delayed gratification in 1970 led by psychologist Walter Mischel, a professor at Stanford University. [1] In this study, a child was offered a choice between one small but immediate reward, or two small rewards if they waited for a period of time.
The Bobo doll experiment (or experiments) is the collective name for a series of experiments performed by psychologist Albert Bandura to test his social learning theory. Between 1961 and 1963, he studied children's behaviour after watching an adult model act aggressively towards a Bobo doll . [ 1 ]
Its favored conformation is at low water concentrations. A-DNAs base pairs are tilted relative to the helix axis, and are displaced from the axis. The sugar pucker occurs at the C3'-endo and in RNA 2'-OH inhibits C2'-endo conformation. [13] Long considered little more than a laboratory artifice, A-DNA is now known to have several biological ...
"Behavioral sink" is a term invented by ethologist John B. Calhoun to describe a collapse in behavior that can result from overpopulation.The term and concept derive from a series of over-population experiments Calhoun conducted on Norway rats between 1958 and 1962. [1]
The sugar experiment lasted until 1949 when the trials were revised again, now to test a more "normal" carbohydrate-rich diet. By then, the teeth of about fifty of the 660 subjects in the experiment had been completely damaged. [8] Nonetheless, the researchers felt that, scientifically speaking, the experiment was a success. [2]
The Little Albert experiment was an unethical study that mid-20th century psychologists interpret as evidence of classical conditioning in humans. The study is also claimed to be an example of stimulus generalization although reading the research report demonstrates that fear did not generalize by color or tactile qualities. [ 1 ]
The test was created by Gerald S. Blum in 1947, [1] who was later Professor of Psychology at the University of Michigan. [2] The drawings depicted a family of cartoon dogs in normal situations which could be related to psychoanalytic theory. The main character, "Blacky", was accompanied by a sibling Tippy, and by a mother and father.
