Edwin Ray Guthrie
Edwin Ray Guthrie (; January 9, 1886 – April 23, 1959), a behavioral psychologist, began his career in mathematics and philosophy in 1917. He spent most of his career at the University of Washington, where he was a full-time professor and later became an emeritus professor in psychology. Guthrie is best known for his works regarding stimulus–response association, which has been variously described as one-trial theory, non-reinforcement, and contiguity learning. He theorized: :"A combination of stimuli which has accompanied a movement, while on its recurrence, tend to be followed by that movement". Guthrie's works and theories were described as "simple" by his peers,Sheffield F.D. 1959. Edwin Ray Guthrie: 1886-1959. ''American Journal of Psychology'', 642-650. referring to how he described complex ideas in simple terms. Critics of Guthrie have considered his teaching style defective, mistaking "incompleteness for simplicity".Mueller C.G. Jr & Schonfeld W.N. 1954. Edwin R. G ...

Origin Of Species
''On the Origin of Species'' (or, more completely, ''On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life'')The book's full original title was ''On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life''. In the 1872 sixth edition, "On" was omitted, so the full title is ''The origin of species by means of natural selection, or the preservation of favoured races in the struggle for life.'' This edition is usually known as ''The Origin of Species.'' The 6th is Darwin's final edition; there were minor modifications in the text of certain subsequent issues. See Freeman, R. B. In Van Wyhe, John, ed. ''Darwin Online: On the Origin of Species'', 2002. is a work of scientific literature by Charles Darwin that is considered to be the foundation of evolutionary biology.

William Kaye Estes
William Kaye Estes (June 17, 1919 – August 17, 2011) was an American psychologist. A ''Review of General Psychology'' survey, published in 2002, ranked Estes as the 77th most cited psychologist of the 20th century. In order to develop a statistical explanation for the learning phenomena, William Kaye Estes developed the Stimulus Sampling Theory in 1950 which suggested that a stimulus-response association is learned on a single trial; however, the learning process is continuous and consists of the accumulation of distinct stimulus-response pairings. Background and education As an undergraduate, Estes was a student of Richard M. Elliott at the University of Minnesota. As a graduate student he stayed at the University of Minnesota, and worked under B. F. Skinner, with whom he developed the conditioned suppression paradigm (Estes & Skinner, 1941). After receiving his doctorate, Estes joined Skinner on the faculty of Indiana University. After Estes got out of the U. S. Army at t ...

Horse Whispering
Natural horsemanship is a collective term for a variety of horse training techniques which have seen rapid growth in popularity since the 1980s. The techniques vary in their precise tenets but generally share principles of "a kinder and gentler cowboy" to develop a rapport with horses, using methods said to be derived from observation of the natural behavior of free-roaming horses and rejecting abusive training methods. Natural horsemanship practitioners often describe the approach as being a radical departure from "traditional" techniques, which are often portrayed as being based in the use of unnecessary force. Users and practitioners tend to relate benefits both in relation to the quasi-scientific narrative of the ethology of horse behavior, viewing the horse as "other", but also to the idea of an anthropomorphic partnership. High-profile practitioners of natural horsemanship such as Monty Roberts and Pat Parelli market their methods and equipment extensively through book ...

Operant Conditioning
Operant conditioning, also called instrumental conditioning, is a learning process in which voluntary behaviors are modified by association with the addition (or removal) of reward or aversive stimuli. The frequency or duration of the behavior may increase through reinforcement or decrease through punishment or Extinction (psychology), extinction. Origins Operant conditioning originated with Edward Thorndike, whose law of effect theorised that behaviors arise as a result of consequences as satisfying or discomforting. In the 20th century, operant conditioning was studied by Behaviorism, behavioral psychologists, who believed that much of mind and behaviour is explained through environmental conditioning. Reinforcements are environmental stimuli that increase behaviors, whereas punishments are stimuli that decrease behaviors. Both kinds of stimuli can be further categorised into positive and negative stimuli, which respectively involve the addition or removal of environmental stim ...

Classical Conditioning
Classical conditioning (also respondent conditioning and Pavlovian conditioning) is a behavioral procedure in which a biologically potent Stimulus (physiology), stimulus (e.g. food, a puff of air on the eye, a potential rival) is paired with a neutral stimulus (e.g. the sound of a Triangle (musical instrument), musical triangle). The term ''classical conditioning'' refers to the process of an automatic, conditioned response that is paired with a specific stimulus. It is essentially equivalent to a signal. The Russian physiology, physiologist Ivan Pavlov studied classical conditioning with detailed experiments with dogs, and published the experimental results in 1897. In the study of digestion, Pavlov observed that the experimental dogs salivated when fed red meat. Pavlovian conditioning is distinct from operant conditioning (instrumental conditioning), through which the strength of a voluntary behavior is modified, either by reinforcement or by Punishment (psychology), punishment ...

Pierre Janet
Pierre Marie Félix Janet (; ; 30 May 1859 – 24 February 1947) was a pioneering French psychologist, physician, philosopher, and psychotherapist in the field of dissociation and traumatic memory. He is ranked alongside William James and Wilhelm Wundt as one of the founding fathers of psychology. He was the first to introduce the link between past experiences and present-day disturbances and was noted for his studies involving induced somnambulism. Biography Janet studied under Jean-Martin Charcot at the Psychological Laboratory in the Salpêtrière Hospital in Paris. He first published the results of his research in his philosophy thesis in 1889 and in his medical thesis, ''L'état mental des hystériques'', in 1892. He earned a medical doctorate the following year after completing a study on the mental state of hysterics. In 1898, Janet was appointed lecturer in psychology at the Sorbonne. In 1901, he founded the French Psychological Society and a year later h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Psychophysics
Psychophysics is the field of psychology which quantitatively investigates the relationship between physical stimulus (physiology), stimuli and the sensation (psychology), sensations and perceptions they produce. Psychophysics has been described as "the scientific study of the relation between stimulus and Sensation (psychology), sensation" or, more completely, as "the analysis of perceptual processes by studying the effect on a subject's experience or behaviour of systematically varying the properties of a stimulus along one or more physical dimensions". ''Psychophysics'' also refers to a general class of methods that can be applied to study a perceptual system. Modern applications rely heavily on threshold measurement, ideal observer analysis, and Detection theory, signal detection theory. Psychophysics has widespread and important practical applications. For instance, in the realm of digital signal processing, insights from psychophysics have guided the development of models a ...

Just Noticeable Difference
In the branch of experimental psychology focused on sense, sensation, and perception, which is called psychophysics, a just-noticeable difference or JND is the amount something must be changed in order for a difference to be noticeable, detectable at least half the time. This limen is also known as the difference limen, difference threshold, or least perceptible difference. Quantification For many sensory modalities, over a wide range of stimulus magnitudes sufficiently far from the upper and lower limits of perception, the 'JND' is a fixed proportion of the reference sensory level, and so the ratio of the JND/reference is roughly constant (that is the JND is a constant proportion/percentage of the reference level). Measured in physical units, we have: \frac = k, where I\! is the original intensity of the particular stimulation, \Delta I\! is the addition to it required for the change to be perceived (the JND), and ''k'' is a constant. This rule was first discovered by Ernst ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aesthesiometer
An esthesiometer (British spelling aesthesiometer) is a device for measuring the tactile sensitivity of the skin (or mouth, or eye, etc.). The measure of the degree of tactile sensitivity is called aesthesiometry. The device was invented by Edward Henry Sieveking. There are different types of aesthesiometers depending on their particular function. Two-point discrimination The simplest is a manual tool with adjustable points similar to a caliper. It can determine how short a distance between two impressions on the skin can be distinguished. To differentiate between two points and one point of equal area (the sum of the areas of the two points equals the area of the third point), Dr. Sidney Weinstein created the three-point esthesiometer. A scale on the instrument gives readings in millimeter gradients. Monofilaments Another type of manual aesthesiometer is used to test lower thresholds of touch or pain. The tool uses nylon monofilaments with varying calibrated diameters. The f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Harry Kirke Wolfe
Harry Kirke Wolfe (November 10, 1858 – July 30, 1918) was a prominent early American psychologist. Early life Harry Kirke Wolfe was born on November 10, 1858, to Jacob Vance Wolfe and Eliza Ellen Batterhorn in Bloomington, Illinois. Both of his parents were teachers. Before her marriage, Ellen Batterhorn taught in public schools and was eventually elected the chair of mathematics at Glendale Woman's College in Glendale, Ohio. After their marriage Jacob Wolfe taught for many years in Illinois and in Gosport, Indiana. Harry was the oldest of their nine children, two of whom died before the age of two. When Harry was thirteen his family moved to a farm near Lincoln, Nebraska. As the eldest son Harry was responsible for working on the farm. He had a deep love of books and often read while walking behind the plow.Benjamin, Ludy T. (1991). ''Harry Kirke Wolfe: pioneer in psychology''.
