Maximilien Ringelmann
Maximilien Ringelmann (10 December 1861, Paris – 2 May 1931, Paris) was a French professor of agricultural engineering and agronomic engineer who was involved in the scientific testing and development of agricultural machinery. Ringelmann's interests were wide-ranging: he developed the Ringelmann scale which is still used to measure smoke. He also discovered the Ringelmann effect in social psychology, viz, that when working in groups, individuals slacken. Education After graduating from the public schools of Paris, Ringelmann studied at the Institute National Agronomique (National Institute of Agronomy), where he was an outstanding student. He also attended Hervé Mangon’s evening course in rural engineering at the Conservatoire National des Arts et Métiers (National Conservatory of Arts and Crafts). (Charles-François Hervé Mangon (1821–1888) had been trained as a civil engineer, but his interest shifted to agriculture, where he studied irrigation, drainage, fert ...

Social Psychologists
Social organisms, including human(s), live collectively in interacting populations. This interaction is considered social whether they are aware of it or not, and whether the exchange is voluntary or not. Etymology The word "social" derives from the Latin word ''socii'' ("allies"). It is particularly derived from the Italian ''Socii'' states, historical allies of the Roman Republic (although they rebelled against Rome in the Social War of 91–87 BC). Social theorists In the view of Karl Marx,Morrison, Ken. ''Marx, Durkheim, Weber. Formations of modern social thought'' human beings are intrinsically, necessarily and by definition social beings who, beyond being "gregarious creatures", cannot survive and meet their needs other than through social co-operation and association. Their social characteristics are therefore to a large extent an objectively given fact, stamped on them from birth and affirmed by socialization processes; and, according to Marx, in producing and reproduci ...

Social Psychology
Social psychology is the methodical study of how thoughts, feelings, and behaviors are influenced by the actual, imagined, or implied presence of others. Although studying many of the same substantive topics as its counterpart in the field of sociology, psychological social psychology places more emphasis on the individual, rather than society; the influence of social structure and culture on individual outcomes, such as personality, behavior, and one's position in social hierarchies. Social psychologists typically explain human behavior as a result of the relationship between mental states and social situations, studying the social conditions under which thoughts, feelings, and behaviors occur, and how these variables influence social interactions. History 19th century In the 19th century, social psychology began to emerge from the larger field of psychology. At the time, many psychologists were concerned with developing concrete explanations for the different aspe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Draught Animals
A working animal is an animal, usually domesticated, that is kept by humans and trained to perform tasks. Some are used for their physical strength (e.g. oxen and draft horses) or for transportation (e.g. riding horses and camels), while others are service animals trained to execute certain specialized tasks (e.g. hunting and guide dogs, messenger pigeons, and fishing cormorants). They may also be used for milking or herding. Some, at the end of their working lives, may also be used for meat or leather. The history of working animals may predate agriculture as dogs were used by hunter-gatherer ancestors; around the world, millions of animals work in relationship with their owners. Domesticated species are often bred for different uses and conditions, especially horses and working dogs. Working animals are usually raised on farms, though some are still captured from the wild, such as dolphins and some Asian elephants. People have found uses for a wide variety of abilities in ...

Social Loafing
In social psychology, social loafing is the phenomenon of a person exerting less effort to achieve a goal when they work in a group than when working alone. It is seen as one of the main reasons groups are sometimes less productive than the combined performance of their members working as individuals. Research on social loafing began with rope pulling experiments by Max Ringelmann, who found that members of a group tended to exert less effort in pulling a rope than did individuals alone. In more recent research, studies involving modern technology, such as online and distributed groups, have also shown clear evidence of social loafing. Many of the causes of social loafing stem from individual members' feeling their individual effort will not matter to the group. This is seen as one of the main reasons groups are sometimes less productive than the combined performance of their members working as individuals, but should be distinguished from the accidental coordination problems th ...
