Hawthorne Study
The Hawthorne effect is a type of human behavior reactivity in which individuals modify an aspect of their behavior in response to their awareness of being observed. The effect was discovered in the context of research conducted at the Hawthorne Western Electric plant; however, some scholars think the descriptions are fictitious. The original research involved workers who made electrical relays at the Hawthorne Works, a Western Electric plant in Cicero, Illinois. Between 1924 and 1927, the lighting study was conducted, wherein workers experienced a series of lighting changes that were said to increase productivity. This conclusion turned out to be false. In an Elton Mayo study that ran from 1927 to 1928, a series of changes in work structure were implemented (e.g. changes in rest periods) in a group of six women. However, this was a methodologically poor, uncontrolled study from which no firm conclusions could be drawn. Elton Mayo later conducted two additional experiments to ...

Reactivity (psychology)
Reactivity is a phenomenon that occurs when individuals alter their performance or behavior due to the awareness that they are being observed. The change may be positive or negative, and depends on the situation. It is a significant threat to a research study's external validity and is typically controlled for using blind experiment designs. There are several forms of reactivity. The Hawthorne effect occurs when research study participants know they are being studied and alter their performance because of the attention they receive from the experimenters. The John Henry effect, a specific form of Hawthorne effect, occurs when the participants in the control group alter their behavior out of awareness that they are in the control group, out of rivalry with the experimental group. Reactivity is not limited to changes in behaviour in relation to being merely observed; it can also refer to situations where individuals alter their behavior to conform to the expectations of th ...

Max Weber
Maximilian Carl Emil Weber (; ; 21 April 186414 June 1920) was a German Sociology, sociologist, historian, jurist, and political economy, political economist who was one of the central figures in the development of sociology and the social sciences more generally. His ideas continue to influence social theory and social research, research. Born in Erfurt in 1864, Weber studied law and history in Humboldt University of Berlin, Berlin, University of Göttingen, Göttingen, and Heidelberg University, Heidelberg. After earning his doctorate in law in 1889 and habilitation in 1891, he taught in Berlin, University of Freiburg, Freiburg, and Heidelberg. He married his cousin Marianne Weber, Marianne Schnitger two years later. In 1897, he had a breakdown after Max Weber Sr., his father died following an argument. Weber ceased teaching and travelled until the early 1900s. He recovered and wrote ''The Protestant Ethic and the Spirit of Capitalism''. During the First World War, he initia ...

Harry Braverman
Harry Braverman (December 9, 1920 – August 2, 1976) Agitating during the Red Scare After serving in the shipbuilding industry during World War II, Braverman began to deepen his commitment to revolutionary struggle, joining the first Trotskyist party in the United States: the Socialist Workers Party (United States), Socialist Workers Party (SWP). His political engagement coincided the wave of political repression against socialists and communists known as the Red Scare. Even before the end of World War II, 18 SWP leaders were imprisoned, becoming "the first victims of the notorious Smith Act, which made it a crime of treason to publish and proclaim the ideas of Marx, Engels, Lenin, and Trotsky." Braverman himself was fired from his job at Republic Steel as a result of red-baiting tactics used by the FBI. Undeterred by the witch-hunts, Braverman continued his political work but disguised his activities by writing under the pseudonym "Harry Frankel". Socialist Unity In the 1950 ...

Educational Research
Educational research refers to the systematic collection and analysis of evidence and data related to the field of education. Research may involve a variety of methods and various aspects of education including student learning, interaction, teaching methods, teacher training, and classroom dynamics. Educational researchers generally agree that research should be rigorous and systematic. However, there is less agreement about specific standards, criteria and research procedures. As a result, the value and quality of educational research has been questioned. Educational researchers may draw upon a variety of disciplines including psychology, economics, sociology, anthropology, and philosophy. Methods may be drawn from a range of disciplines. Conclusions drawn from an individual research study may be limited by the characteristics of the participants who were studied and the conditions under which the study was conducted. General characteristics Gary Anderson outlined ten aspect ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mica
Micas ( ) are a group of silicate minerals whose outstanding physical characteristic is that individual mica crystals can easily be split into fragile elastic plates. This characteristic is described as ''perfect basal cleavage''. Mica is common in igneous and metamorphic rock and is occasionally found as small flakes in sedimentary rock. It is particularly prominent in many granites, pegmatites, and schists, and "books" (large individual crystals) of mica several feet across have been found in some pegmatites. Micas are used in products such as drywalls, paints, and fillers, especially in parts for automobiles, roofing, and in electronics. The mineral is used in cosmetics and food to add "shimmer" or "frost". Properties and structure The mica group comprises 37 phyllosilicate minerals. All crystallize in the monoclinic system, with a tendency towards pseudohexagonal crystals, and are similar in structure but vary in chemical composition. Micas are translucent to opa ...

Experimenter Effect
The observer-expectancy effect is a form of reactivity in which a researcher's cognitive bias causes them to subconsciously influence the participants of an experiment. Confirmation bias can lead to the experimenter interpreting results incorrectly because of the tendency to look for information that conforms to their hypothesis, and overlook information that argues against it. It is a significant threat to a study's internal validity, and is therefore typically controlled using a double-blind experimental design. It may include conscious or unconscious influences on subject behavior including creation of demand characteristics that influence subjects, and altered or selective recording of experimental results themselves. Overview The experimenter may introduce cognitive bias into a study in several in the observer-expectancy effect, the experimenter may subtly communicate their expectations for the outcome of the study to the participants, causing them to alter their beh ...

Manipulation Checks
Manipulation check is a term in experimental research in the social sciences which refers to certain kinds of secondary evaluations of an experiment. Overview Manipulation checks are measured variables that show what the manipulated variables concurrently affect besides the dependent variable of interest. In experiments, an experimenter manipulates some aspect of a process or task and randomly assigns subjects to different levels of the manipulation ("experimental conditions"). The experimenter then observes whether variation in the manipulated variables cause differences in the dependent variable. Manipulation checks are targeted at variables beside the dependent variable of interest. Manipulations are not intended to verify that the manipulated factor caused variation in the dependent variable. This is verified by random assignment, manipulation before measurement of the dependent variable, and statistical tests of effect of the manipulated variable on the dependent variabl ...

Martin Theodore Orne
Martin Theodore Orne (October 16, 1927, Vienna, Austria – February 11, 2000, Paoli, Pennsylvania, US) was a professor of psychiatry and psychology at the University of Pennsylvania. Orne is best known for his pioneering research into demand characteristics, illustrating the weakness of informing participants that they are taking part in a psychology experiment and yet expecting them to act normally. He was well known as a researcher in the field of hypnosis and is also noted for his involvement with the poet Anne Sexton, and with the trials of Patty Hearst and Kenneth Bianchi. Personal life and education Orne was born on October 16, 1927, to Frank Orne, a surgeon and Martha Brunner, a psychiatrist in Vienna, Austria. His family moved from Austria to escape the Nazi Anschluss and relocated to New York City in 1938. He studied at the Bronx High School of Science. He later moved to Boston and studied at Harvard University. Orne enlisted in the U.S. Army during World War II a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Peer Group
In sociology, a peer group is both a social group and a primary group of people who have similar interests ( homophily), age, background, or social status. Members of peer groups are likely to influence each others' beliefs and behaviour. During adolescence, peer groups tend to face dramatic changes. Adolescents tend to spend more time with their peers and have less adult supervision. Peer groups give a sense of security and identity. A study found that during the adolescent phase as adolescents spend double time with their peers compared to the time youth spend with their parents. Adolescents' communication shifts during this time as well. They prefer to talk about school and their careers with their parents, and they enjoy talking about sex and other interpersonal relationships with their peers. Children look to join peer groups who accept them, even if the group is involved in negative activities. Children are less likely to accept those who are different from them. Friendship ...
