  • 1. Learning Theories

2. Definitions of Learning 1. a persisting change in human performance or performance potential . . . (brought) about as a result of the learners interaction with the environment (Driscoll, 1994, pp. 8-9).the relatively permanent change in a persons knowledge or behavior due to experience (Mayer, 1982, p. 1040). 3. an enduring change in behavior, or in the capacity to behave in a given fashion, which results from practice or other forms of experience (Shuell, 1986, p. 412). 2. 3. Classical Conditioning Ivan Pavlov (1849-1936) 4. Ivan Pavlov Pavlov, a Russianphysiologist, first described classical conditioning in 1899 while conducting research into the digestive system of dogs. 5. Pavlovs Research Pavlov used anapparatus to measure the amount of saliva produced when a dog ate. The flow of saliva occurred naturally whenever food was placed in the dogs mouth, as salivation is an involuntary, reflex response. 6. Pavlovs Observation A stimulus is any event that elicits a response from an organism. A response is a reaction by an organism to a stimulus. In Pavlovs experiment, the stimulus of food initially produced the response of salivation. The salivation response is controlled by the autonomic division of the PNS. Involuntary. The salivation had become associated with, and conditioned to, a new stimulus the lab tech. 7. Pavlovs Basic Principles Acquisition- period during which aresponse is being learned. Unconditioned Stimulus (UCS) Unconditioned Response (UCR) Conditioned Stimulus (CS) Conditioned Response (CR) 8. Before conditioning CarNo fear, no anxietyDuring conditioning Car (CS) + Traumatic accident (UCS) After conditioningCars (CS)Fear, AnxietyFear, Anxiety 9. Pavlovs Basic Principles Extinction- the CS is presentedrepeatedly in the absence of UCS, causing the CR to weaken and eventually disappear. (Extinction Trial) Spontaneous Recovery- the reappearance of a previously extinguished CR after a rest period and without new learning trials. Generalization- stimuli similar to the initial CS elicit a CR. 10. Pavlovs Basic Principles Discrimination- demonstrated when aCR (alarm reaction) occurs to one stimulus (sound) but not to others. Higher-order Conditioning- a neutral stimulus becomes a CS after being paired with an already established CS. 11.

Instrumental Learning Thorndikes Law of effect > In a given situation, a response followed by a satisfying consequence will become more likely to occur and a response followed by an annoying consequence will become less likely to occur. 15. Instrumental Learning A procedure in which an organismlearns that certain responses are instrumental in producing desired effects in the environment 16. Operant Conditioning Came from B.F. Skinners studyon how an organism learns to operate on its environment to produce an effect Is a type of learning in which behavior is influenced by the consequence that follow it. 17. Skinner Box a specialchamber used by Skinner to study operant conditioning experimentally 18. Events Of The Three-part Consistency A.) ANTECEDENTS stimuli that are present before a behavior occurs B.) BEHAVIORS action or response an organism emits C.) CONSEQUENCES follows the behavior CONTINGENCY is the relation between the behaviorand consequence 19. Consequences That Shape Behavior 1. Reinforcement response is strengthened by an outcome that follows it Reinforcer o The outcome that increases the frequency of a response 20. Reinforcements 1.1. PositiveReinforcement when the response is strengthened bythe subsequent Presentation of a stimulus 1.2. Negative Reinforcement a response is strengthened by the subsequent Removal of an aversive stimulus 21. Shaping And Chaining 1. Shapingreinforcing successive approximations toward a final response2. Chaining use to develop a sequence of responses by reinforcing each responses with the opportunity to perform the next response 22. Shaping And Chaining 23. Immediate And Delayed Reinforcers 1. ImmediateReinforcers Occurs INSTANTLY after a behavior2.Delayed Reinforcers Delayed in time for a certain behavior Man is inclined to pursue small immediate reinforcers rather than large delayed reinforcers. 24. Reinforcement Schedules Continuous Reinforcement Every response of a particular type is reinforced 2. Partial (Intermittent) Reinforcement1. only a portion of the responses of a particular type are reinforced 25. Ratio Schedule 2.1. Fixed-ratio Schedule (FR) Reinforcement is given after a fixednumber of responses2.2 Variable-ratio Schedule (VR) Reinforcement is given after a variable(unpredictable)number of responses Averaged around some mean 26. Ratio Schedule 2.3. Fixed-interval Schedule (FI) Reinforces the first response displayed after a fixed time interval 2.4. Variable- Interval Schedule (VI) reinforces a response at unpredictable time intervals ( averaged around a mean) Produces slow, steady responses 27. Consequences That Shape Behavior 2. Punishment When response is weakened byoutcomes that follow it PUNISHER o Consequence that weakens the behavior 28. Punishments 2.1 . Aversive Punishment o Positive punishment or punishment by application o A response is weakened by the subsequent presentation of a stimulus 2.2. Response Cost o Negative punishment or punishment by removal o Response is weakened by a subsequent removal of a stimulus 29. Consequences That Shape Behavior 3. Extinction weakening and eventual disappearance of aresponse because it is no longer reinforced A good alternative for punishment Resistance To Extinction o Degree to which nonreinforced responses still persist low resistance high resistance 30. Consequences That Shape Behavior 31. Generalization And Discrimination 1. GENERALIZATIONOccurs to a new antecedent stimulus or situation that is similar to the original one2.DISCRIMINATION Operant response will occur to oneantecedent stimulus but not to another STIMULUS CONTROL obehavior that is influenced by discriminative stimuli 32. Observational Learning Albert Bandura (1925- present) 33. Observational Learning Identified by Albert Bandura Learning through observation and imitation Most common during childhood Significant role in the socialization process Belief that people can adapt new informationwithout committing new behaviors. 34. Factors That Influence Observational Learning People we perceive as warm and nurturing People who receive rewards for theirbehavior When you have been rewarded for imitatingthe behavior in the past When we lack confidence in our ownknowledge or abilities 35. Factors That Influence Observational Learning People who are in a position of authority overour lives People who are similar to us in age, sex, andinterests People who we admire or who are of a highersocial status When the situation is confusing, ambiguous,or unfamiliar 36. Social-learning theory Also known as Social-cognitive theory Learning that processes through observationof a certain models behavior Acquiring belief that people can produce behaviors to influence events in their lives Modeling mans ability to learn by observation Self-efficacy peoples belief in their capability toproduce a particular situation they desired 37. Three basic models of observational learning 1. A live model an individual demonstrating abehavior 2. A verbal instructional model descriptions andexplanations of a behavior 3. A symbolic model real or fictional charactersdisplaying behaviors 38. Factors in the Four-step process of modeling Attention paying attention to the modelsbehavior Retention storing the information in memory Reproduction performing the modelsbehavior Motivation being motivated to display the 39.
