Ethology is the scientific study of animal behaviour, usually with a focus on behaviour under natural conditions, and viewing behaviour as an evolutionarily adaptive trait. Behaviourism as a term also describes the scientific and objective study of animal behaviour, usually referring to measured responses to stimuli or to trained behavioural responses in a laboratory context, without a particular emphasis on evolutionary adaptivity. Throughout history, different naturalists have studied aspects of animal behaviour. Ethology has its scientific roots in the work of Charles Darwin and of American and German ornithologists of the late 19th and early 20th century, including Charles O. Whitman, Oskar Heinroth, and Wallace Craig. The modern discipline of ethology is generally considered to have begun during the 1930s with the work of Dutch biologist Nikolaas Tinbergen and Austrian biologists Konrad Lorenz and Karl von Frisch, the three recipients of the 1973 Nobel Prize in Physiology or Medicine. Ethology combines laboratory and field science, with a strong relation to some other disciplines such as neuroanatomy, ecology, and evolutionary biology. Ethologists typically show interest in a behavioural process rather than in a particular animal group, and often study one type of behaviour, such as aggression, in a number of unrelated species.
Konrad Zacharias Lorenz 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.
Perception is the organization, identification, and interpretation of sensory information in order to represent and understand the presented information or environment. All perception involves signals that go through the nervous system, which in turn result from physical or chemical stimulation of the sensory system. Vision involves light striking the retina of the eye; smell is mediated by odor molecules; and hearing involves pressure waves.
Operant conditioning is a type of associative learning process through which the strength of a behavior is modified by reinforcement or punishment. It is also a procedure that is used to bring about such learning.
Nikolaas "Niko" Tinbergen 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.
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.
A supernormal stimulus or superstimulus is an exaggerated version of a stimulus to which there is an existing response tendency, or any stimulus that elicits a response more strongly than the stimulus for which it evolved.
Animal cognition encompasses the mental capacities of non-human animals including insect cognition. The study of animal conditioning and learning used in this field was developed from comparative psychology. It has also been strongly influenced by research in ethology, behavioral ecology, and evolutionary psychology; the alternative name cognitive ethology is sometimes used. Many behaviors associated with the term animal intelligence are also subsumed within animal cognition.
Neuroethology is the evolutionary and comparative approach to the study of animal behavior and its underlying mechanistic control by the nervous system. It is an interdisciplinary science that combines both neuroscience and ethology. A central theme of neuroethology, which differentiates it from other branches of neuroscience, is its focus on behaviors that have been favored by natural selection rather than on behaviors that are specific to a particular disease state or laboratory experiment.
Content theory is a subset of motivational theories that try to define what motivates people. Content theories of motivation often describe a system of needs that motivate peoples' actions. While process theories of motivation attempt to explain how and why our motivations affect our behaviors, content theories of motivation attempt to define what those motives or needs are. Content theory includes the work of David McClelland, Abraham Maslow and other psychologists.
Salience is the state or condition of being prominent. The Oxford English Dictionary defines salience as "most noticeable or important." The concept is discussed in communication, semiotics, linguistics, sociology, psychology, and political science. It has been studied with respect to interpersonal communication, persuasion, politics, and its influence on mass media.
A fixed action pattern is an ethological term describing an instinctive behavioral sequence that is highly stereotyped and species-characteristic. Fixed action patterns are said to be produced by the innate releasing mechanism, a "hard-wired" neural network, in response to a sign/key stimulus or releaser. Once released, a fixed action pattern runs to completion.
Roger Newland Shepard was an American cognitive scientist and author of the "universal law of generalization" (1987). He was considered a father of research on spatial relations. He studied mental rotation, and was an inventor of non-metric multidimensional scaling, a method for representing certain kinds of statistical data in a graphical form that can be apprehended by humans. The optical illusion called Shepard tables and the auditory illusion called Shepard tones are named for him.
The term Cartesian linguistics was coined by Noam Chomsky in his book Cartesian Linguistics: A Chapter in the History of Rationalist Thought (1966). The adjective "Cartesian" pertains to René Descartes, a prominent 17th-century philosopher. As well as Descartes, Chomsky surveys other examples of rationalist thought in 17th-century linguistics, in particular the Port-Royal Grammar (1660), which foreshadows some of his own ideas concerning universal grammar.
A sense is a biological system used by an organism for sensation, the process of gathering information about the world through the detection of stimuli. Although traditionally five human senses were identified as such, it is now recognized that there are many more. Senses used by non-human organisms are even greater in variety and number. During sensation, sense organs collect various stimuli for transduction, meaning transformation into a form that can be understood by the brain. Sensation and perception are fundamental to nearly every aspect of an organism's cognition, behavior and thought.
Deirdre Barrett is an American author and psychologist known for her research on dreams, hypnosis and imagery, and has written on evolutionary psychology. Barrett is a teacher at Harvard Medical School, and a past president of the International Association for the Study of Dreams and of the American Psychological Association’s Div. 30, the Society for Psychological Hypnosis. She is editor-in-chief of the journal Dreaming: The Journal of the Association for the Study of Dreams and a consulting editor for Imagination, Cognition, and Personality and The International Journal for Clinical and Experimental Hypnosis.
Motivating operation (MO) is a behavioristic concept introduced by Jack Michael in 1982. It is used to explain variations in the effects in the consequences of behavior. Most importantly, an MO affects how strongly the person is reinforced or punished by the consequences of their behavior. For example, food deprivation is a motivating operation; if a person is hungry, food is strongly reinforcing, but if a person is satiated, food is less reinforcing. In 2003 Laraway suggested subdividing MOs into those that increase the reinforcing or punishing effects of a stimulus, which are termed establishing operations, and MOs that decrease the reinforcing or punishing effects of a stimulus, which are termed abolishing operations.
Human ethology is the study of human behavior. Ethology as a discipline is generally thought of as a sub-category of biology, though psychological theories have been developed based on ethological ideas. The bridging between biological sciences and social sciences creates an understanding of human ethology. The International Society for Human Ethology is dedicated to advancing the study and understanding of human ethology.
How Art Made the World is a 2005 five-part BBC One documentary series, with each episode looking at the influence of art on the current day situation of our society.
Waistland: The R/evolutionary Science Behind Our Weight and Fitness Crisis is a book by Harvard psychologist Deirdre Barrett published by W. W. Norton & Company in 2007. The book examines the obesity and fitness crisis from an evolutionary standpoint. Barrett argues that our bodies, our metabolisms, and our feeding instincts evolved during humanity’s hunter-gatherer phase. We're programmed to forage for sugar and saturated fats because these were once found only in hard-to-come-by fruit and game. Now, these same foods are everywhere—in vending machines, fast food joint, restaurants, grocery stores, and school cafeterias—they're nearly impossible to avoid. She describes this as related to the focus of another of her books " supernormal stimuli"—the concept of artificial creations that appeal more to our instincts than the natural objects they mimic—supernormal stimuli for appetite have led to the obesity epidemic. The book opens with a vignette about how zoos post signs saying "Don't Feed the Animals." People respect these orders, allowing veterinarians to prescribe just the right balanced diet for the lions, koalas, and snakes. Meanwhile, everyone stops for chips, sodas, and hot dogs on the way out of the zoo. The book explores solutions from behavior modification to willpower to change diet and exercise habits. One of the main messages of the book is that big changes in diet are actually easier than small ones, that the addictive nature of junk food means that, after a few days, eating no cookies or chips is easier than eating fewer cookies or chips.
