Key Questions What sort of learning does Classical
Conditioning explain? How do we learn new behaviors by operant
conditioning? How does cognitive psychology explain
learning?
The Psychology of Learning?
… a process through which experience produces a lasting change in behavior or mental processes.◦ Lasting Change
Not Reflexes: An action that is performed involuntary or automatic as a response to a stimulus.
◦ Behavior and mental processes Behavior: The way one acts in response to stimulus Mental Processes: the things we do with our mind
What is Learning?
Empirical and Measureable Evidence Behaviorists Belief Cognitive Psychologists Belief
Observing Mental Processes
Instincts: An ability to behave in a certain way coupled with a tendency to behave that way at appropriate times.
Fight-or-flight Nursing Eating; drinking Seeking better resources Blink, flinch Display emptions
What does learning do for us?
Habituation◦ Not responding to stimuli
Mere exposure effect◦ Attraction to stimuli previously experienced
Sensitization◦ Becoming sensitive to emotional events or
situations

Classical ConditioningWhat sort of learning does Classical
Conditioning explain?
Russian Physiologist studying digestion Dogs: salivating before eating
Classical Conditioning: a basic form of learning in which a stimulus that produces an innate reflex becomes associated with a previously neutral stimulus, which then acquires the power to elicit essentially the same response.
Ivan Pavlov (1849-1936)
Neutral Stimulus Unconditioned Stimulus ● UCS Unconditioned Response ● UCR Acquisition Conditioned Stimulus ●CS Conditioned Response ● CR

Extinction: Conditioned responses fade
Spontaneous Recovery: Conditioned responses may reappear
ICE CREAM
Generalization: Bit by one dog but afraid of all dogs
Discrimination: Not all bells cause salivation

Little Albert White rat (NS)+ loud noise (Aversive UCS)= fear of white rat (CR)
Generalized fear of other furry objects

Conditioning Human Fear*
Mary Cover Jones Peter-fear of white rats “Degrees of Toleration” Extinction + learning relaxation to CS =
relaxed response to CS
Counterconditioning Therapy
Learning in which a stimulus that produces an innate reflex becomes associated with a previously neutral stimulus, which then elicits essentially the same response.
What is Classical Conditioning?
Answer the following question on paper and turn in it to the box by the door as you leave.
What sort of learning does Classical Conditioning explain?
Operant ConditioningHow do we learn new behaviors by operant
conditioning?
Psychologist Radical Behaviorist Consequences change behavior Remove subjectivity – only observable data
Operant Conditioning is a form of learning where the consequences of behavior, such as rewards and punishments, influence the chance that the behavior will occur again.
B. F. Skinner (1904-1990)
Reinforcer: Reward-a condition that strengthens a response
Positive Reinforcement: A condition that encourages a response by giving a incentive
Negative Reinforcement: A condition that encourages a response by removing an aversion
Reinforcement
Continuous Reinforcement◦ The best strategy for teaching and learning new
behavior Intermittent Reinforcement
◦ The most efficient way to maintain behaviors already learned
◦ Resistance to Extinction
Reinforcement Contingencies
Ratio Schedules: Reward given based on numbers of responses◦ Fixed Ratio: number of responses for
reward remains constant◦ Variable Ratio: number of responses
for reward varies Interval Schedules: Reward is
based on responses made in side a time period◦ Fixed Interval: Time period between
rewards remains constant◦ Variable Interval: Time period
between rewards varies
Schedules of Reinforcement
Shaping Behavior
Shaping: Teaching a new behavior by reinforcing responses that are similar to the desired response

Positive Punishment: Application of aversive stimulus
Negative Punishment: Removal of reinforcer
Punishment
Reflection What is something you have learned that
was the result of positive or negative reinforcement?

Cognitive PsychologyHow does cognitive psychology explain
learning?
The Core Concept of Cognitive Psychology is that some forms of learning must be explained as changes in mental processes rather than as changes in behavior alone.
Cognitive Psychology
Wolfgang Köhler German Psychologist Marooned in the Canary Islands WWI
Köhler: Thinking/Accessing memory essential components to learning
Sudden perception of familiar objects in new forms or relationships

Insight Learning
Can you see any plausible explanation for the chimps learning to get the fruit using Classical or Operant conditioning?
Edward Tolman Learning resulted from bits of knowledge
and thoughts about the environment and how an organism relates to it
Mental Images = Cognitive Maps
Cognitive Maps
Albert Bandura (Social Learning) Rewards can be effective at motivating a
response even if we see others get them
BoBo doll experiment Watching violent behavior influenced
observer to act aggressively

Observational Learning
Anagrams Group 1
◦ BAT◦ LEMON
Group 2◦ WHIRL◦ SLAPSTICK
Learned Helplessness Martin Seligman Results from experiencing uncontrollable
events that cause an individual to expect future lack of control
Decreased motivation, failure to learn, sadness, anxiety, frustration
Latent Learning Hidden learning that occurs without
reinforcement, becoming apparent only when a reward is introduced.
Group A-Always rewarded Group B- Never rewarded Group C-Rewarded later
State Dependent Learning You recall information easily when you are
in the same physiological or emotional state or setting you were when you originally encoded the information.
Motivation
Intrinsic
Internal desires to engage in a task; actions that promote happiness, develop a skill, or is just the right thing to do (moral)
Extrinsic
Factors outside of the individual and the task itself; Earning money, grades, other rewards
With a partner discuss…In general, are people you know more driven by intrinsic or extrinsic motivation?

Think-Pair-Share
Think of a time during your school career when you were able to learn the subject you were studying very easily.
What do you think the reasons were that you were able to learn the subject so easily?
Is it easier to work on and finish jobs that you are interested in?
