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 ]
Picture arrangement test is a test that consists of a series of comic-strip-like pictures that are presented in a random order. The subject is given the task to arrange the pictures as quickly as possible so that a reasonable and meaningful story is formed. This is an example of a common feature found in intelligence tests. [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 ...
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.
"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 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.
Gollin conducted four experiments. In experiment I, 53 children aged 30–65 months and a comparison group of 20 adults were recruited. The test consisted in a series of 11 objects [bell, bird, birthday cake, chair, cow, fish, goose, horse, table (viewed from above and from below), umbrella] each drawn five times (set I, II, III, IV and V) with black ink on a white 14 in × 9 in (360 mm × 230 ...
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 ]
