Introduction of Learning Concepts

  • ==Learning== – any relatively permanent change in behavior that occurs due to experience

  • ==Behaviorism== – school of psychology that accounts for behavior in terms of observable events

  • ==Conditioning== – involves forming associations between environmental stimuli and responses

    • Classical conditioning

    • Operant conditioning

  • Other theories reject the idea of omitting mental processes from explanations of human behavior

    • Social learning theories

    • Cognitive theories

Classical Conditioning

New reflexes from old
  • ==Pavlov== was the first to describe and document the form of learning we now call classical conditioning

  • Terminology :

    • ==Unconditioned stimulus (US)== – stimulus eliciting an automatic or reflexive response

    • ==Unconditioned response (UR)== – response that is automatically produced

    • ==Conditioned stimulus (CS)== – an originally neutral stimulus that comes to elicit a conditioned response after being paired with a US

    • ==Conditioned response (CR)== – response that is elicited by a CS

  • ==Learning== occurs when a neutral stimulus is regularly paired with a US and the neutral stimulus becomes a CS that elicits a CR that is similar to the original, unlearned one

  • Classical conditioning is also called Pavlovian or respondent conditioning

Principles of Classical Conditioning
  • ==Extinction== – when the conditioned stimulus is presented repeatedly without the unconditioned stimulus, the conditioned response eventually disappears

  • ==Spontaneous recovery== – after a response has been extinguished, it may spontaneously reappear after the passage of time, with exposure to the conditioned stimulus

  • ==Higher‐order conditioning== – a neutral stimulus can become a conditioned stimulus by being paired with an already established conditioned stimulus

  • ==Stimulus generalization== – after a stimulus becomes a conditioned stimulus for some response, similar stimuli may produce the same reaction

  • ==Stimulus discrimination== – different responses are triggered by stimuli that resemble the conditioned stimulus in some way

What is really learned in classical conditioning?
  • For effective conditioning to occur, it is not enough to pair the stimuli; the neutral stimulus must reliably signal the unconditioned one

  • Conditioning is less certain in everyday life

Classical Conditioning in Real Life

  • Learning to like

  • Learning to fear

    • Some things may be more easily learned because of a biological predisposition based on evolutionary considerations

    • Little Albert example

    • Therapy techniques that have developed to reverse classically conditioned fears include ==counterconditioning== and ==systematic desensitization==

  • Accounting for taste – food and odor likes and dislikes

  • Reacting to medical treatments

Operant Conditioning

The birth of radical behaviorism
  • Introduced at the turn of the twentieth century

  • Thorndike observed that behavior is controlled by its consequences

  • B.F. Skinner – behavior is explainable by looking outside of the individual

The Consequences of Behavior
  • A response can lead to three types of consequences: neutral consequences, ==reinforcers== : increase the probability that the response they follow will recur, and ==punishers== : make the response they follow less likely to recur

  • Consequences are most effective when there is no delay between response and consequence

Primary and secondary reinforcers and punishers
  • ==Primary reinforcers== satisfy biological needs

  • ==Primary punishers== are inherently unpleasant

  • ==Secondary reinforcers== are reinforcing through association with other (possibly primary) reinforcers

  • ==Secondary punishers== are punishing through association with other punishers

Positive and negative reinforcers and punishers
  • ==Reinforcers== – always increase the likelihood of a response

    • ==Positive reinforcement== – something pleasant is presented

    • ==Negative reinforcement== – something unpleasant is removed

  • ==Punishers== – decrease the likelihood of a response

    • ==Positive punishment== – something unpleasant occurs

    • ==Negative punishment== – something pleasant is removed

Principles of operant conditioning
  1. Skinner boxes and cumulative recorders are often used when conditioning animals

  2. ==Extinction== – a previously learned response stops occurring because it is no longer
    reinforced

  3. ==Spontaneous recovery== is the return of a response that has been extinguished

  4. ==Stimulus generalization== – a response occurs to stimuli that resemble the stimuli present during the original learning

  5. ==Stimulus discrimination== – the ability to distinguish between similar stimuli and to respond only to the one that results in the reinforcer

  6. ==Discriminative stimulus== is a signal whether a response will pay off; it is said to exert stimulus control over the response because it signals whether the conditions in which the response will be reinforced are present

  7. ==Schedule of reinforcement== – the pattern of delivery of reinforcements; can have powerful effects on rate, form, and timing of behavior

    • ==Continuous reinforcement== – reinforcing a response each time it occurs; most effective for initial learning

    • ==Partial or intermittent schedules== – reinforcement occurs only after a certain amount of time has passed or only after a certain number of responses have been made

    • ==Superstitious behavior== can be learned when behavior is coincidentally reinforced

    • ReinforcementonanintermittentschedulemakesaresponsemoreresistanttoextinctionwhenreinforcementisdiscontinuedReinforcement on an intermittent schedule makes a response more resistant to extinction when reinforcement is discontinued$$Reinforcement on an intermittent schedule makes a response more resistant to extinction when reinforcement is discontinued$$

  8. ==Shaping== - method of getting a response to occur in the first place by reinforcing successive approximations to the desired response

  9. Principles of conditioning are limited by genetic dispositions and physical characteristics

    1. Skinner : The man and the myth

Operant Conditioning in Real Life

  • ==Operant principles== may explain why people do not always behave as we or they would like

  • ==Behavior modification== – the use of classical and operant conditioning techniques in real world settings
