Displacement Activity
Displacement activities occur when an animal experiences high motivation for two or more conflicting behaviours: the resulting displacement activity is usually unrelated to the competing motivations. Birds, for example, may peck at grass when uncertain whether to attack or flee from an opponent; similarly, a human may scratch their head when they do not know which of two options to choose. Displacement activities may also occur when animals are prevented from performing a single behaviour for which they are highly motivated. Displacement activities often involve actions which bring comfort to the animal such as scratching, preening, drinking or feeding. In the assessment of animal welfare, displacement activities are sometimes used as evidence that an animal is highly motivated to perform a behaviour that the environment prevents. One example is that when hungry hens are trained to eat from a particular food dispenser and then find the dispenser blocked, they often begin to pace a ...

Nikolaas Tinbergen
Nikolaas "Niko" Tinbergen (; ; 15 April 1907 – 21 December 1988) was a Dutch biologist and ornithologist who shared the 1973 Nobel Prize in Physiology or Medicine with Karl von Frisch and Konrad Lorenz for their discoveries concerning the organization and elicitation of individual and social behavior patterns in animals. He is regarded as one of the founders of modern ethology, the study of animal behavior. In 1951, he published ''The Study of Instinct'', an influential book on animal behaviour. In the 1960s, he collaborated with filmmaker Hugh Falkus on a series of wildlife films, including ''The Riddle of the Rook'' (1972) and ''Signals for Survival'' (1969), which won the Italia prize in that year and the American blue ribbon in 1971. Education and early life Born in The Hague, Netherlands, he was one of five children of Dirk Cornelis Tinbergen and his wife Jeannette van Eek. His brother, Jan Tinbergen, won the first Bank of Sweden Prize in Economic Sciences in Memory o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Procrastination
Procrastination is the action of unnecessarily and voluntarily delaying or postponing something despite knowing that there will be negative consequences for doing so. The word has originated from the Latin word ''procrastinatus'', which itself evolved from the prefix ''pro-'', meaning "forward," and ''crastinus'', meaning "of tomorrow." Oftentimes, it is a habitual human behaviour. It is a common human experience involving delay in everyday chores or even putting off salient tasks such as attending an appointment, submitting a job report or academic assignment, or broaching a stressful issue with a partner. Although typically perceived as a negative trait due to its hindering effect on one's productivity often associated with depression, low self-esteem, guilt and inadequacy, it can also be considered a wise response to certain demands that could present risky or negative outcomes or require waiting for new information to arrive. From a cultural and a social perspective, studen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ethogram
An ethogram is a catalogue or inventory of behaviours or actions exhibited by an animal used in ethology. The behaviours in an ethogram are usually defined to be mutually exclusive and objective, avoiding subjectivity and functional inference as to their possible purpose. For example, a species may use a putative threat display, which in the ethogram is given a descriptive name such as "head forward" or "chest-beating display", and not "head forward threat" or "chest-beating threat". This degree of objectivity is required because what looks like "courtship" might have a completely different function, and in addition, the same motor patterns in different species can have very different functions (e.g. tail wagging in cats and dogs). Objectivity and clarity in the definitions of behaviours also improve inter-observer reliability. Often, ethograms are hierarchical in presentation. The defined behaviours are recorded under broader categories of behaviour which may allow functiona ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Displacement (psychology)
In psychology, displacement (german: Verschiebung, lit=shift, move) is an unconscious defence mechanism whereby the mind substitutes either a new aim or a new object for goals felt in their original form to be dangerous or unacceptable. Freud The concept of displacement originated with Sigmund Freud. Initially he saw it as a means of dream-distortion, involving a shift of emphasis from important to unimportant elements, or the replacement of something by a mere illusion. Freud called this “displacement of accent.” Displacement of object: Feelings that are connected with one person are displaced onto another person. A man who has had a bad day at the office, comes home and yells at his wife and children, is displacing his anger from the workplace onto his family. Freud thought that when children have animal phobias, they may be displacing fears of their parents onto an animal. Displacement of attribution: A characteristic that one perceives in oneself but seems unacceptable ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Julian Huxley
Sir Julian Sorell Huxley (22 June 1887 – 14 February 1975) was an English evolutionary biologist, eugenicist, and internationalist. He was a proponent of natural selection, and a leading figure in the mid-twentieth century modern synthesis. He was secretary of the Zoological Society of London (1935–1942), the first Director of UNESCO, a founding member of the World Wildlife Fund, the president of the British Eugenics Society (1959-1962), and the first President of the British Humanist Association. Huxley was well known for his presentation of science in books and articles, and on radio and television. He directed an Oscar-winning wildlife film. He was awarded UNESCO's Kalinga Prize for the popularisation of science in 1953, the Darwin Medal of the Royal Society in 1956, and the Darwin–Wallace Medal of the Linnaean Society in 1958. He was also knighted in that same year, 1958, a hundred years after Charles Darwin and Alfred Russel Wallace announced the theory of evoluti ...

The Little White Bird
''The Little White Bird'' is a novel by the Scottish writer J. M. Barrie, ranging in tone from fantasy and whimsy to social comedy with dark, aggressive undertones. It was published in November 1902, by Hodder & Stoughton in the UK and Scribner's in the US (and the latter also published it serially in the monthly '' Scribner's Magazine'' from August to November). The book attained prominence and longevity thanks to several chapters written in a softer tone than the rest of the book, which introduced the character and mythology of Peter Pan. In 1906, those chapters were published separately as a children's book, ''Peter Pan in Kensington Gardens''. The Peter Pan story began as one chapter and grew to an "elaborate book-within-a-book" of more than one hundred pages during the four years Barrie worked on ''The Little White Bird''. The complete book has also been published under the title ''The Little White Bird, or Adventures in Kensington Gardens''. Plot introduction ''The L ...

Adriaan Kortlandt
Prof. Dr. Adriaan Kortlandt (25 January 1918, Rotterdam - 18 October 2009, Amsterdam) was a Dutch ethologist. He was famous for his work on displacement activities (Dutch: ''overspronggedrag)'' and the hierarchy of instincts. Already in the thirties he realised the common characteristics between instincts in humans and other animals. In one of his experiments in Western Africa he exposed a stuffed panther with an electronic moving head to chimpanzees, who attacked it with sticks, thus illustrating to which extent early man could have kept wild animals at bay even before spears and other weapons were invented. He also was the author of the "Rift Valley theory",Kortlandt, A. (1972) - ''New perspectives on ape and human evolution'', Amsterdam, Stichting voor Psychobiologie. better known under the name given by French paleoanthropologist Yves Coppens Yves Coppens (9 August 1934 – 22 June 2022) was a French anthropologist.

Konrad Lorenz
Konrad Zacharias Lorenz (; 7 November 1903 – 27 February 1989) was an Austrian zoologist, ethologist, and ornithologist. He shared the 1973 Nobel Prize in Physiology or Medicine with Nikolaas Tinbergen and Karl von Frisch. He is often regarded as one of the founders of modern ethology, the study of animal behavior. He developed an approach that began with an earlier generation, including his teacher Oskar Heinroth. Lorenz studied instinctive behavior in animals, especially in greylag geese and jackdaws. Working with geese, he investigated the principle of imprinting, the process by which some nidifugous birds (i.e. birds that leave their nest early) bond instinctively with the first moving object that they see within the first hours of hatching. Although Lorenz did not discover the topic, he became widely known for his descriptions of imprinting as an instinctive bond. In 1936 he met Tinbergen, and the two collaborated in developing ethology as a separate sub-discipline ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Motivation
Motivation is the reason for which humans and other animals initiate, continue, or terminate a behavior at a given time. Motivational states are commonly understood as forces acting within the agent that create a disposition to engage in goal-directed behavior. It is often held that different mental states compete with each other and that only the strongest state determines behavior. This means that we can be motivated to do something without actually doing it. The paradigmatic mental state providing motivation is desire. But various other states, such as beliefs about what one ought to do or intentions, may also provide motivation. Motivation is derived from the word 'motive', which denotes a person's needs, desires, wants, or urges. It is the process of motivating individuals to take action in order to achieve a goal. The psychological elements fueling people's behavior in the context of job goals might include a desire for money. Various competing theories have been proposed co ...

Negative Affect
Negative affectivity (NA), or negative affect, is a personality variable that involves the experience of negative emotions and poor self-concept. Negative affectivity subsumes a variety of negative emotions, including anger, contempt, disgust, guilt, fear, and nervousness. Low negative affectivity is characterized by frequent states of calmness and serenity, along with states of confidence, activeness, and great enthusiasm. Individuals differ in negative emotional reactivity.Tellegen, A. (1985). Structures of mood and personality and their relevance to assessing anxiety, with an emphasis on self-report. In A. H. Tuma & J. D. Maser (Eds.), Anxiety and the Anxiety disorders, (pp. 681-706), Hilssdale, NJ: Erlbaum. Trait negative affectivity roughly corresponds to the dominant personality factor of anxiety/neuroticism that is found within the Big Five personality traits as emotional stability. The Big Five are characterized as openness, conscientiousness, extraversion, agreeableness, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
