Title: What is learning


1
What is learning?
  • A relatively permanent change in organisms
    behavior due to experience provided that the
    behavior is not due to a native response tendency
    or temporary state
  • Learned association are an important part of
    learning theories
  • associate stimuli together anticipate events
  • associate responses and consequences
  • Observation and experience are another key part
    of learning

2
Classical Conditioning
  • Who was Pavlov and his dogs?
  • Experiments on salivary conditioning
  • Observed that dogs salivate when presented with
    food
  • Noticed that dogs would also begin to salivate
    when items were associated with food
  • Classic experiments with bells/tone

Key Terms in Classical Conditioning
  • Unconditioned stimulus
  • e.g., food
  • Unconditioned response
  • e.g., salivation
  • Conditioned stimulus
  • e.g., tone
  • Conditioned response
  • e.g., salivation to bell

Example 1 This camper makes me sick!
  • UCS
  • UCR
  • CS
  • CR

6
Key Processes
  • Acquisition-initial learning
  • Extinction and spontaneous recovery
  • neutral stimulus will go back to not having an
    effect if repeatedly presented without UCS
  • suppression rather than elimination of response
  • Generalization-responding to a similar stimuli
  • Discrimination

Spontaneous Recovery

Example
  • UCS
  • UCR
  • CS
  • CR

10
Operant Conditioning
  • Who is Skinner and what is a Skinner box?
  • Focus on associations between behavior and
    consequences
  • Process includes shaping
  • reinforces approximations of appropriate behaviors

11
Key Terms
  • Reinforcement-any event that increases frequency
    of response
  • Positive Reinforcement adds something positive
  • Negative reinforcement takes away something
    aversive
  • Punishment an event intended to decrease the
    behavior

Reinforcement Increases a behavior
  • Is it negative reinforcement?
  • Taking an aspirin to relieve a headache
  • Giving in to your toddlers whining for candy
  • Putting a child in time out for whining
  • Turning down the volume of a very loud radio
  • Giving your child dessert for eating a good
    dinner
  • Smoking to relieve anxiety
  • Not having to take a final because of good
    performance

14
Reinforcement schedules
  • Continuous vs partial reinforcement
  • Types of Schedules
  • Fixed ratio
  • Variable ratio
  • Fixed interval
  • Variable interval

15
Intermittent Reinforcement Schedules
16
Punishment
  • How is punishment different than negative
    reinforcement?
  • Punishment decreases in a behavior
  • What are some problems with punishment?
  • Behavior may continue when punisher is not
    present
  • May be related to increased aggression levels
  • Does not guide people towards desired behavior

17
Role of cognition in association theories
  • To a strict behaviorist-expectations (or thinking
    about events) to not have an effect
  • To those who consider a cognitive perceptive,
    there is evidence that we do think about
    associations
  • over justification effect
  • More likely to learn associations that help us
    survive

18
Observation Learning
  • Bandura suggested that we learn through direct
    experience as well as associations
  • Modeling observing and imitating others
    behaviors
  • Experiments with the Booboo Dolls
