Mand (psychology)
Mand is a term that B.F. Skinner used to describe a verbal operant in which the response is reinforced by a characteristic consequence and is therefore under the functional control of relevant conditions of deprivation or aversive stimulation. One cannot determine, based on form alone, whether a response is a mand; it is necessary to know the kinds of variables controlling a response in order to identify a verbal operant. A mand is sometimes said to "specify its reinforcement" although this is not always the case. Skinner introduced the mand as one of six primary verbal operants in his 1957 work, ''Verbal Behavior''. Chapter three of Skinner's work, ''Verbal Behavior'', discusses a functional relationship called the mand. A mand is a form of verbal behavior that is controlled by deprivation, satiation, or what is now called motivating operations (MO), as well as a controlling history. An example of this would be asking for water when one is water deprived ("thirsty"). It is tempti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Verbal Behavior
''Verbal Behavior'' is a 1957 book by psychologist B. F. Skinner, in which he describes what he calls verbal behavior, or what was traditionally called linguistics. Skinner's work describes the controlling elements of verbal behavior with terminology invented for the analysis - ''echoics, mands, tacts, autoclitics'' and others - as well as carefully defined uses of ordinary terms such as ''audience''. Origins The origin of ''Verbal Behavior'' was an outgrowth of a series of lectures first presented at the University of Minnesota in the early 1940s and developed further in his summer lectures at Columbia and William James lectures at Harvard in the decade before the book's publication. Research Skinner's analysis of verbal behavior drew heavily on methods of literary analysis. This tradition has continued. The book ''Verbal Behavior'' is almost entirely theoretical, involving little experimental research in the work itself. Many research papers and applied extensions based o ...

Stimulus Control
In behavioral psychology, stimulus control is a phenomenon in operant conditioning that occurs when an organism behaves in one way in the presence of a given Stimulus (psychology), stimulus and another way in its absence. A stimulus that modifies behavior in this manner is either a wikt:discriminative stimulus, discriminative stimulus or wikt:stimulus delta, stimulus delta. For example, the presence of a stop sign at a traffic intersection alerts the driver to stop driving and increases the probability that braking behavior occurs. Stimulus control does not force behavior to occur, as it is a direct result of historical reinforcement three-term contingency, contingencies, as opposed to reflexive behavior elicited through classical conditioning. Some theorists believe that all behavior is under some form of stimulus control. For example, in the analysis of B. F. Skinner, Verbal Behavior, verbal behavior is a complicated assortment of behaviors with a variety of controlling stimuli. ...

Intermittent Reinforcement
In behavioral psychology, reinforcement refers to consequences that increase the likelihood of an organism's future behavior, typically in the presence of a particular '' antecedent stimulus''. For example, a rat can be trained to push a lever to receive food whenever a light is turned on; in this example, the light is the antecedent stimulus, the lever pushing is the '' operant behavior'', and the food is the ''reinforcer''. Likewise, a student that receives attention and praise when answering a teacher's question will be more likely to answer future questions in class; the teacher's question is the antecedent, the student's response is the behavior, and the praise and attention are the reinforcements. Punishment is the inverse to reinforcement, referring to any behavior that decreases the likelihood that a response will occur. In operant conditioning terms, punishment does not need to involve any type of pain, fear, or physical actions; even a brief spoken expression of disapp ...

Developmental Disabilities
Developmental disability is a diverse group of chronic conditions, comprising mental or physical impairments that arise before adulthood. Developmental disabilities cause individuals living with them many difficulties in certain areas of life, especially in "language, mobility, learning, self-help, and independent living".Center for Disease Control and Prevention. (2013)Developmental disabilities.Retrieved October 18, 2013 Developmental disabilities can be detected early on and persist throughout an individual's lifespan. Developmental disability that affects all areas of a child's development is sometimes referred to as global developmental delay. The most common developmental disabilities are: * Motor disorders, and learning difficulties such as dyslexia, Tourette's syndrome, dyspraxia, dysgraphia, dyscalculia, and nonverbal learning disorder. * autistic spectrum disorders, Autism spectrum disorder (ASD, formerly the pervasive developmental disorders, PDD umbrella covering Asperg ...

Imperative Mood
The imperative mood is a grammatical mood that forms a command or request. The imperative mood is used to demand or require that an action be performed. It is usually found only in the present tense, second person. They are sometimes called ''directives'', as they include a feature that encodes directive force, and another feature that encodes modality of unrealized interpretation. An example of a verb used in the imperative mood is the English phrase "Go." Such imperatives imply a second-person subject (''you''), but some other languages also have first- and third-person imperatives, with the meaning of "let's (do something)" or "let them (do something)" (the forms may alternatively be called cohortative and jussive). Imperative mood can be denoted by the glossing abbreviation . It is one of the irrealis moods. Formation Imperative mood is often expressed using special conjugated verb forms. Like other finite verb forms, imperatives often inflect for person and nu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tact (psychology)
Tact is a term that B.F. Skinner used to describe a verbal operant which is controlled by a nonverbal stimulus (such as an object, event, or property of an object) and is maintained by nonspecific social reinforcement ( praise). Less technically, a tact is a label. For example, a child may see their pet dog and say "dog"; the nonverbal stimulus (dog) evoked the response "dog" which is maintained by praise (or generalized conditioned reinforcement) "you're right, that is a dog!" Chapter five of Skinner's ''Verbal Behavior'' discusses the tact in depth. A tact is said to "make contact with" the world, and refers to behavior that is under the control of generalized reinforcement. The controlling antecedent stimulus is nonverbal, and constitutes some portion of "the whole of the physical environment." The tact described by Skinner includes three important and related events, known as the 3-term-contingency: a stimulus, a response, and a consequence, in this case reinforcement. A v ...
