John Henry Effect
The John Henry effect is an experimental bias introduced into social experiments by reactive behavior by the control group. In a controlled social experiment if a control is aware of their status as members of the control group and is able to compare their performance with that of the treatment group, members of the control group may actively work harder to overcome the "disadvantage" of being in the control group. For example, if in an educational trial where the school classes who are in the treatment receive an extra support teacher, students who are in the control group may be induced to work harder to overcome that disadvantage. The term was first used by Gary Saretsky (1972) to describe the behavior of John Henry, a legendary American steel driver in the 1870s who, when he heard his output was being compared with that of a steam drill, worked so hard to outperform the machine that he died in the process.

Social Experiment
A social experiment is a type of Psychology, psychological or Sociology, sociological research for testing people's reactions to certain situations or events. The experiment depends on a particular social approach where the main source of information is the point of view and knowledge of the participants of the experiment. To carry out a social experiment, specialists usually split participants into two groups — active participants (people who take action in particular events) and respondents (people who react to the action). Throughout the experiment, participants are monitored by specialists to identify the effects and differences as a result of the experiment. Intentional community, Intentional communities are generally considered as social experiments. Social psychology offers insight into how individuals act in groups and how behavior is affected by social burdens and pressures. In most social experiments, the subjects are unaware that they are partaking in an experiment. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. 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 the observer.

Control Group
In the design of experiments, hypotheses are applied to experimental units in a treatment group. In comparative experiments, members of a control group receive a standard treatment, a placebo, or no treatment at all. There may be more than one treatment group, more than one control group, or both. A placebo control group can be used to support a double-blind study, in which some subjects are given an ineffective treatment (in medical studies typically a sugar pill) to minimize differences in the experiences of subjects in the different groups; this is done in a way that ensures no participant in the experiment (subject or experimenter) knows to which group each subject belongs. In such cases, a third, non-treatment control group can be used to measure the placebo effect directly, as the difference between the responses of placebo subjects and untreated subjects, perhaps paired by age group or other factors (such as being twins). For the conclusions drawn from the results of an e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Henry (folklore)
John Henry is an American folk hero. An African American, he is said to have worked as a "steel-driving man"—a man tasked with hammering a steel drill into rock to make holes for explosives to blast the rock in constructing a railroad tunnel. The story of John Henry is told in a classic blues folk song, which exists in many versions, and has been the subject of numerous stories, plays, books, and novels. Legend According to legend, John Henry's prowess as a steel driver was measured in a race against a steam-powered rock drilling machine, a race that he won only to die in victory with a hammer in hand as his heart gave out from stress. Various locations, including Big Bend Tunnel in West Virginia, Lewis Tunnel in Virginia, and Coosa Mountain Tunnel in Alabama, have been suggested as the site of the contest. The contest involved John Henry as the hammerman working in partnership with a shaker, who would hold a chisel-like drill against mountain rock, while the hammerman st ...

Hawthorne Effect
The Hawthorne effect is a type of 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 feel the descriptions are apocryphal. 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. Workers experienced a series of lighting changes in which productivity was said to increase with almost any change in the lighting. This turned out ''not'' to be true. In the study that was associated with Elton Mayo, which ran from 1928 to 1932, a series of changes in work structure were implemented (e.g., changes in rest periods) in a group of five women. However, this was a methodologically poor, uncontrolled study that did not permit any firm conclusions to be drawn. One of ...

John Henryism
John Henryism (JH) is a strategy for coping with prolonged exposure to stresses such as social discrimination by expending high levels of effort which results in accumulating physiological costs. Origins The term was conceived in the 1970s by African-American epidemiologist and public health researcher Sherman James while he was investigating racial health disparities between Black people and others in North Carolina. One of the people he interviewed was a black man, who, despite being born into an impoverished sharecropper family and having only a second grade education, could read and write. The man had freed himself and his children from the sharecropper system, had of farmed land by age 40, but by his 50s, he had hypertension, arthritis, and severe peptic ulcer disease. His name, John Henry Martin, and his circumstances were evocative of folk hero John Henry, an African American who worked vigorously enough to compete successfully with a steam powered machine but die ...

Social Phenomena
Social phenomena or social phenomenon (singular) are any behaviours, actions, or events that takes place because of social influence, including from contemporary as well as historical societal influences. They are often a result of multifaceted processes that add ever increasing dimensions as they operate through individual nodes of people. Because of this, social phenomenon are inherently dynamic and operate within a specific time and historical context. Social phenomena are observable, measurable data. Psychological notions may drive them, but those notions are not directly observable; only the phenomena that express them. See also * Phenomenological sociology * Sociological imagination Sociological imagination is a term used in the field of sociology to describe a framework for understanding social reality that places personal experiences within a broader social and historical context. It was coined by American sociologist C ... References {{Reflist Sociological t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
