Flashcards in Chapter 12-Behaviorism Deck (48)
Shared Sechenov's goal of creating a totally objective psychology. Focused his study on the conditioned and unconditioned stimuli that control behavior and on the physiological processes that they initiate. For him, all human behaviour is reflexive
The reduction or cessation of activity caused by stimulation, such as when extinction causes a conditioned stimulus to inhibit a conditioned response. It was Sechenov's Discovery of inhibitory mechanisms in the brain that led him to believe that all human behavior could be explained in terms of brain physiology
Describe Pavlov's work in studying the digestive processes
Using a patient who had suffered a severe gunshot wound to the stomach and recovered but had an open hole in his body through which his internal organs could be observed, Pavlov observed his internal processes, including those of the digestive system and perfected his technique for studying digestion.
He prepared a gastric fistula-a channel-leading from a dog's digestive organs to outside the dogs body. He performed hundreds of experiments to determine how the amount of secretion through the fist you love varied as a function of different types of stimulation to the digestive system which one him the 1904 Nobel Prize in physiology
A learned reflex
Describe Pavlov's discovery of the conditioned reflex
While studying the secretion of the dogs gastric juices in response to such substances as meat powder, pavlov noticed that objects or events associated with meat powder also caused stomach secretions-for example, the mere sight of the experimenter or the sound of his or her footsteps. He referred to these latter responses as conditional because they depended on something else-for example, meet powder
Describe Pavlov's personality
He was a positivist and was totally dedicated to his laboratory work. He wrote very little. He encouraged both women and Jewish students to study in his laboratory, a practice very uncommon at the time. One thing he had no tolerance for was mentalism-if researchers in his laboratory used mentalistic terminology to describe their feelings, he fined them
In his private life, however, Pavlov was a completely different person. He was sentimental, impractical, and absent-minded-often arousing the wonder and amusement of his friends. He often forgot to pick up his pay, and often loaned it to irresponsible acquaintances. Him and his wife lived in extreme poverty during the early years of their marriage but she continued to give him her complete support.
An unlearned reflex
A stimulus that elicits an unconditioned response
An innate response elicited by the unconditioned stimulus that is naturally associated with it
A previously biologically neutral stimulus that, through experience, comes to elicit a certain response
A response elicited by a conditioned stimulus
Describe Pavlov's Believe about the process of formation of a conditioned reflex
And unconditioned reflex is innate and is triggered by an unconditioned stimulus, for example, placing food powder in a hungry dogs mouth will increase the dog saliva flow. The food powder is the unconditioned stimulus, and the increased salvation is the unconditioned response.
Pavlov called a biologically neutral stimulus a conditioned stimulus. Because of its contiguity with an unconditioned stimulus, in this case food, this previously neutral stimulus developed the capacity to elicit some fraction of the unconditioned response, in this case salivation.
When a previously neutral stimulus a conditioned stimulus, elicits some fraction of an unconditioned response, the reaction is called a conditioned response. Thus, a dog salivating to the sound of an attendants footsteps exemplifies a conditioned response
According to Pavlov, brain activity that leads to overt behavior of some type
According to Pavlov, the pattern of points of excitation and inhibition that characterizes the cortex at any given moment
The elimination or reduction of a conditioned response that results when a conditioned stimulus is presented but is not followed by the unconditioned stimulus
The reappearance of a conditioned response after a delay following extinction
The inhibition of an inhibitory process. Is demonstrated when, after extinction, a loud noise causes the conditioned response to appear
The assumption was that the fear caused by the strong stimulus displaces the inhibitory process, thus allowing the return of the conditioned response
The neurotic behavior that pavlov created in some of his laboratory animals by bringing excitatory and inhibitory tendencies into conflict
Example: showing a dog a circle is always followed by food and showing a dog an ellipse is never followed by food. According to Pavlov, the circle will come to elicit salivation and the ellipse will inhibit salivation. If the circle increasingly becomes more elliptical and the circle and the ellipse become indistinguishable, The excitatory and the inhibitory tendencies will conflict, and the animals behavior will break down
According to Pavlov, those objects or events that become signals for the occurrence of biologically significant events, such as when a tone signals the eventuality of food
Innate processes are expanded by conditioning. As biologically neutral stimuli (CSs) are consistently associated with biologically significant stimuli (USs), The former come to signal the biologically significant events. The adaptive significance of such signals should be obvious; if an animal is warned that something either conducive or threatening to survival is about to happen, it will have time to engage in appropriate behavior
According to Pavlov, the symbols of objects or events that signal the occurrence of biologically significant events. Seeing fire and withdrawing from it would exemplify the first-signal system, but escaping in response to hearing the word fire exemplifies the second-signal system
Describe Pavlov's view of psychology
He had a low opinion of psychology not because it studied consciousness but because it used introspection to do so
Describe Pavlov's view of associationism as it had been previously discussed in philosophy
He believed that he had discovered the physiological mechanism for explaining the associationism that philosophers and psychologists had been discussing for centuries. He believed that by showing the physiological underpinnings of Association, he had put associationism on an objective footing and that speculation about how ideas become associated with each other could finally end.
The temporary connections formed by conditioning or precisely the associations that had been the focus of philosophical and psychological speculation
The founder of behaviorism who established psychology's goal as the prediction and control of behavior. In his final position, he denied the existence of mental events and concluded that instincts play no role in human behavior. On the mind-body problem, he finally became a physical monist, believing that thought is nothing but implicit muscle movement
John B. Watson
Describe Watsons undergraduate experiences
Despite his history of laziness and violence in school, Watson somehow managed to get himself excepted to Furman University at the age of 15. Continued to live at home and worked at a chemical laboratory to pay his fees. He learned the psychology of Wundt and James and had problems with his brother Edward, who considered him a sinner like his father and therefore a disgrace to the family
He should have graduated in 1898, but an unusual event set him back a year. Moore, his favorite teacher, warned that he would flunk any student who handed his or her examination in backward. Absentmindedly, Watson handed in his examination backward and was flunked.
It actually ended up benefiting Watson, however, because during the extra year he earned a masters degree
Describe Watson's graduate school years at the university of Chicago
Watson began to investigate the learning process in the white rat at the time when very little was known about animal learning. By the end of 1902, Watson knew more about the white rat than anyone else in United States and begin to develop a feeling for behaviorism but his mentor Angelle responded negatively and silenced Watson for four years.
In 1906, he began his researched designed to determine what sensory information rats used as they learned to solve a complex maze. Using six month old brass that had previously learned the maze, Watson began systematically removing one sensory system after another, in hopes of learning which sensory system the rats used to traverse the maze correctly. He removed the senses a vision, hearing, and smell and nothing appeared to make a difference. Found that the rats were relying on kinesthetic sensation-sensations from the muscles
Describe Watsons professorship at John Hopkins University
He did not want to leave the University of Chicago but was offered a $3000 A year salary that was irresistible. He taught human psychology using Ticheners manuals.
Baldwin was chairman of the department and was caught in a brothel and was forced to resign from John Hopkins immediately. Upon Baldwin's resignation, Watson became the editor of the psychological review, and ultimately he used to journal to publish his views on behaviorism.
After many years of being discouraged for his behavioristic positions, he publicly announced his behavioristic views in 1908 at a meeting at Yale University and was severely criticized and again fell silent. In 1913 he gained courage again and decided to state his views at a series of lectures at Columbia University. That lecture is usually taken as a formal founding of behaviorism and was published in 1913 in the psychological review. His ideas did not gain immediate popularity but grew steadily over a period of several years
Describe Watsons scandalous divorce
In 1920 his wife discovered that he was having an affair with Rosalie Rayner with whom he was doing research on infant behavior and she sued him for divorce. The scandal was too much for Johns Hopkins: Watson was asked to resign and he did. This marked the end of Watsons professional career in psychology
Describe Watson's work in advertising
An opportunity arose for him to work for the advertising company J. Walter Thompson. The job contrasted sharply with what he had grown accustomed to.
His job was to study the rubber boot market on each side of the Mississippi River.
He was hired in 1921 at a salary of $10,000 a year and was considered one of the leading people in advertising and was made a vice president of the company. By 1928 he was earning over $50,000 a year, and by 1930 over $70,000.
He introduced the concept of market research and found, for example, that blindfolded smokers cannot differentiate among different brands of cigarettes. Because preference must be based on the images associated with various brand names, Watson concluded that sales could be influenced by manipulating the images associated with branding. Following the strategy, he increased the sales of such products as Johnson's baby powder, toothpaste, Ponds cold cream, maxwell house coffee, and Odorono one of the early deodorants
Describe Watsons objective psychology
Like the Russian objective psychologists, Watson completely rejected introspection and any explanation of behavior based on mentalism. Both thought that consciousness could not cause behavior; it was merely a phenomenon that accompanied certain physiological reactions caused by stimuli- and epiphenomena on.
