Instinct Killers
Instinct is the inherent inclination of a living organism towards a particular complex behaviour, containing both innate (inborn) and learned elements. The simplest example of an instinctive behaviour is a fixed action pattern (FAP), in which a very short to medium length sequence of actions, without variation, are carried out in response to a corresponding clearly defined stimulus. Any behaviour is instinctive if it is performed without being based upon prior experience (that is, in the absence of learning), and is therefore an expression of innate biological factors. Sea turtles, newly hatched on a beach, will instinctively move toward the ocean. A marsupial climbs into its mother's pouch upon being born. Other examples include animal fighting, animal courtship behaviour, internal escape functions, and the building of nests. Though an instinct is defined by its invariant innate characteristics, details of its performance can be changed by experience; for example, a dog can imp ...

Life
Life is a quality that distinguishes matter that has biological processes, such as signaling and self-sustaining processes, from that which does not, and is defined by the capacity for growth, reaction to stimuli, metabolism, energy transformation, and reproduction. Various forms of life exist, such as plants, animals, fungi, protists, archaea, and bacteria. Biology is the science that studies life. The gene is the unit of heredity, whereas the Cell (biology), cell is the structural and functional unit of life. There are two kinds of cells, prokaryotic and eukaryotic, both of which consist of cytoplasm enclosed within a membrane and contain many biomolecules such as proteins and nucleic acids. Cells reproduce through a process of cell division, in which the parent cell divides into two or more daughter cells and passes its genes onto a new generation, sometimes producing genetic variation. Organisms, or the individual entities of life, are generally thought t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wilhelm Wundt
Wilhelm Maximilian Wundt (; ; 16 August 1832 – 31 August 1920) was a German physiologist, philosopher, and professor, known today as one of the fathers of modern psychology. Wundt, who distinguished psychology as a science from philosophy and biology, was the first person ever to call himself a psychologist. He is widely regarded as the "father of experimental psychology"."Wilhelm Maximilian Wundt" in ''Stanford Encyclopedia of Philosophy''. In 1879, at the , Wundt founded the first formal laboratory for psychological research. This marked psychology as an independent field of study. By creating this laboratory he was able to establish psychology a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Comparative Psychology
Comparative psychology refers to the scientific study of the behavior and mental processes of non-human animals, especially as these relate to the phylogenetic history, adaptive significance, and development of behavior. Research in this area addresses many different issues, uses many different methods and explores the behavior of many different species from insects to primates. Comparative psychology is sometimes assumed to emphasize cross-species comparisons, including those between humans and animals. However, some researchers feel that direct comparisons should not be the sole focus of comparative psychology and that intense focus on a single organism to understand its behavior is just as desirable; if not more so. Donald Dewsbury reviewed the works of several psychologists and their definitions and concluded that the object of comparative psychology is to establish principles of generality focusing on both proximate and ultimate causation.Dewsbury, D. (1984). ''Comparative Psy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Frank Beach
Frank Ambrose Beach, Jr. (April 13, 1911 – June 15, 1988) was an American ethologist, best known as co-author of the 1951 book ''Patterns of Sexual Behavior.'' He is often regarded as the founder of behavioral endocrinology, as his publications marked the beginnings of the field. Early education and career Frank Ambrose Beach, Jr. was born in Emporia, Kansas, the first of three children to Frank Ambrose Beach and Bertha Robinson Beach.Dewsbery, Donald A. (2000) "Frank A. Beach, Master Teacher," ''Portraits of Pioneers in Psychology, Volume 4,'' p269-281 Although he respected his father, a distinguished Professor of Music at Kansas State Teachers College (now Emporia State University), Frank Beach Jr. often rebelled against him. Frank A. Beach Jr. rarely used the Jr. associated with his name. Beach began an English major at Emporia, with the intent to become a high school English teacher. Beach was a poor student, receiving D's and F's at Emporia, so he was sent to Antioch Co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Imprinting (psychology)
In psychology and ethology, imprinting is any kind of phase-sensitive learning (learning occurring at a particular age or a particular life stage) that is rapid and apparently independent of the consequences of behaviour. It was first used to describe situations in which an animal or person learns the characteristics of some stimulus, which is therefore said to be "imprinted" onto the subject. Imprinting is hypothesized to have a critical period. Filial imprinting The best-known form of imprinting is ''filial imprinting'', in which a young animal narrows its social preferences to an object (typically a parent) as a result of exposure to that object. It is most obvious in nidifugous birds, which imprint on their parents and then follow them around. It was first reported in domestic chickens, by Sir Thomas More in 1516 as described in his treatise ''Utopia'', 350years earlier than by the 19th-century amateur biologist Douglas Spalding. It was rediscovered by the early ethologist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
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] |
Abraham Maslow
Abraham Harold Maslow (; April 1, 1908 – June 8, 1970) was an American psychologist who was best known for creating Maslow's hierarchy of needs, a theory of psychological health predicated on fulfilling innate human needs in priority, culminating in self-actualization. Maslow was a psychology professor at Brandeis University, Brooklyn College, New School for Social Research, and Columbia University. He stressed the importance of focusing on the positive qualities in people, as opposed to treating them as a "bag of symptoms". Hoffmann (1988), p. 109. A ''Review of General Psychology'' survey, published in 2002, ranked Maslow as the tenth most cited psychologist of the 20th century. Biography Youth Born in 1908 and raised in Brooklyn, New York, Maslow was the oldest of seven children. His parents were first-generation Jewish immigrants from Kiev, then part of the Russian Empire (now Kyiv, Ukraine), who fled from Czarist persecution in the early 20th century. They had deci ...

Neuroplasticity
Neuroplasticity, also known as neural plasticity, or brain plasticity, is the ability of Neural circuit, neural networks in the brain to change through growth and reorganization. It is when the brain is rewired to function in some way that differs from how it previously functioned. These changes range from individual neuron pathways making new connections, to systematic adjustments like cortical remapping. Examples of neuroplasticity include circuit and network changes that result from learning a new ability, environmental influences, practice, and psychological stress. Neuroplasticity was once thought by neuroscientists to manifest only during childhood, but research in the latter half of the 20th century showed that many aspects of the brain can be altered (or are "plastic") even through adulthood. However, the developing brain exhibits a higher degree of plasticity than the adult brain. Activity-dependent plasticity can have significant implications for healthy development, le ...

Propensity
The propensity theory of probability is a probability interpretation in which the probability is thought of as a physical propensity, disposition, or tendency of a given type of situation to yield an outcome of a certain kind, or to yield a long-run relative frequency of such an outcome.'Interpretations of Probability', Stanford Encyclopedia of Philosophybr> Retrieved 23 December 2006. Propensities are not relative frequencies, but purported ''causes'' of the observed stable relative frequencies. Propensities are invoked to ''explain why'' repeating a certain kind of experiment will generate a given outcome type at a persistent rate. A central aspect of this explanation is the law of large numbers. This law, which is a consequence of the axioms of probability, says that if (for example) a coin is tossed repeatedly many times, in such a way that its probability of landing heads is the same on each toss, and the outcomes are probabilistically independent, then the relative freq ...

Emotion
Emotions are mental states brought on by neurophysiological changes, variously associated with thoughts, feelings, behavioral responses, and a degree of pleasure or displeasure. There is currently no scientific consensus on a definition. Emotions are often intertwined with mood, temperament, personality, disposition, or creativity. Research on emotion has increased over the past two decades with many fields contributing including psychology, medicine, history, sociology of emotions, and computer science. The numerous theories that attempt to explain the origin, function and other aspects of emotions have fostered more intense research on this topic. Current areas of research in the concept of emotion include the development of materials that stimulate and elicit emotion. In addition, PET scans and fMRI scans help study the affective picture processes in the brain. From a mechanistic perspective, emotions can be defined as "a positive or negative experience that is as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
William McDougall (psychologist)
William McDougall FRS (; 22 June 1871 – 28 November 1938) was an early 20th century psychologist who spent the first part of his career in the United Kingdom and the latter part in the United States. He wrote a number of influential textbooks, and was important in the development of the theory of instinct and of social psychology in the English-speaking world. McDougall was an opponent of behaviourism and stands somewhat outside the mainstream of the development of Anglo-American psychological thought in the first half of the 20th century; but his work was known and respected among lay people. Biography He was born at Tonge, Middleton in the Manchester area on 22 June 1871, the second son of Isaac Shimwell McDougall and his wife Rebekah Smalley. His father was one of the McDougall brothers who developed self-raising flour, but concentrated on his own business as a chemical manufacturer. McDougall was educated at a number of schools, and was a student at Owens College, Man ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
