Types of Learning 1) Habituation 2) Classical Conditioning 3) Operant Conditioning
Operant Conditioning Edward Thorndike
Gradually it escapes quicker A specific response become “strengthened” by being paired with a pleasant outcome
Law of Effect "Of several responses made to the same situation those which are accompanied or closely followed by satisfaction to the animal will, other things being equal, be more firmly connected with the situation, so that, when it recurs, they will be more likely to recur; those which are accompanied or closely followed by discomfort to the animal will, other things being equal, have their connections to the situation weakened, so that, when it recurs, they will be less likely to occur. Note: It is missing information about the internal state of the animal Thorndike used hungry cats and rats!
Clark Hull
Needs Behavior is not just a function of the environment but also. . . Properties of the organism
All animals have certain needs (food) Creates drives (drive for food) Reducing drive (by eating) reinforces the behavior (eating)
Learning Both Hull and Thorndike felt their learning was the same as Pavlov’s classical conditioning
Hot and Cold Game
Skinner
B. F. Skinner Noted differences between the types of learning. How is classical conditioning different then either Thorndike’s or Hull’s theories?
Operant Conditioning Classical = animal does nothing to its environment. Operant = The animal alters its environment.
Reinforcement Theory Operant Conditioning Behavior Reward Used to control behavior Behavior Reward Behaviors that are rewarded are more likely to be performed in the future

Group Activity Identify one behavior in yourself that you would like to change Determine a system of rewards and punishments that you could use to change this behavior Do you think this would work?
Did Skinner really raise his daughter in a Skinner Box? Picture from Ladies' Home Journal: "Baby in a Box.”
Question Why are you going to college? What are you dating someone? Why are you listening to this lecture? You do all of these things because of a long history of rewards and punishments!
Classical vs. Operant Conditioning “Reactions” to the world Emotions Traits: anxiousness, neuroticism, depression Operant “Actions” toward the world Behaviors Traits: Extraversion, argumentativeness, kindness
Behaviorism Pros Cons Controlling behavior Focus on the observable Mental life Motivation Thought Cognition
Next theories Keep the empirical rigor of behaviorism and add. . . . Cognition, thought, motivation, etc. Social learning In Skinner box animals are alone We learn by watching others! Treat humans as active in selecting their environment In Skinner box a rat is placed in there We select our environments and they will change because we are in them You at a party!
Theories Dollard and Miller’s Social Learning Theory Rotter’s Social Learning Theory Bandura’s Social Learning Theory
Dollard & Miller
Dollard and Miller Combines behaviorism and Freudian theory!
Habit Hierarchy All the behaviors a person might do From most likely to least likely
Habit Hierarchy Talk to Ponch Get a drink Talk to a woman Comb hair In a bar Comb hair But, this can change based on reinforcement or punishment Flex muscles
Activity Create your own habit hierarchy for being in the classroom List Top 5 habits Why do you think these are the top 5? How do you think we could change these?
In order to learn -- John (an organism) must 1) Want something (a woman) 2) Notice something (perceive the woman) 3) Do something (talk to the woman) 4) Get something (a smile)
Note This is already different than behaviorism Dollard and Miller Motivation (want something) Perception (notice something)
Note This is already different than behaviorism Behaviorism Learning changes behavior Dollard and Miller Learning changes the HH HH is a non-observable psychological entity
What do you want? Drives A psychological tension that feels good when it is reduced. Need Drive
Drives Primary Drives Biologically built-in drives Secondary Drives Food, water, sex, avoid pain, etc. Secondary Drives Psychologically based Love, prestige, money, power, etc. Learned by being paired with primary drives
Imagine John asks the Charlie's Angels out on a date John gets rejected! Is upset so he goes riding with Ponch Arrests a person for no reason at all!
Why? Freud Frustration-Aggression Hypothesis Natural reaction for any person (or animal) to being blocked from a goal, will be the urge to lash out or injure. The more important the goal, the greater will be the aggressive impulse
Frustration-Aggression Hypothesis Different than Freud No ID is needed (or ego) Same as Freud Displacement e.g., riots Sublimation (can be constructive)
What is fun? The story about me in the book
Approach-Avoidance Conflict Conflict between desire and fear Changes over time
Approach-Avoidance Conflict 1) An increase in drive strength will increase the tendency to approach or avoid a goal VS. If John wants to relieve a drive more than Ponch, John will also want the goal more!
Approach-Avoidance Conflict 2) Whenever there are two competing responses, the stronger one (the one with the greater drive) will win out. Drive: Companionship Drive: Avoid rejection
Approach-Avoidance Conflict 3) The tendency to approach a positive goal increases the closer the one is to the goal John sees the Angels across the room John talks to them John asks them back to his place
Approach-Avoidance Conflict 3) The tendency to approach a positive goal increases the closer the one is to the goal
Approach-Avoidance Conflict 4) The tendency to avoid a negative goal also increases the closer one is to the goal John sees the Angels across the room John talks to them John asks them back to his place
Approach-Avoidance Conflict 5) Tendency 4 is stronger than tendency 3. Avoidance Approach
Approach-Avoidance Conflict 5) Tendency 4 is stronger than tendency 3. Avoidance Approach
Approach-Avoidance Conflict 5) Tendency 4 is stronger than tendency 3. Avoidance Approach
Approach-Avoidance Conflict 5) Tendency 4 is stronger than tendency 3. Avoidance Approach
Group Activity Have you ever had something in the future that you were both looking forward to and dreading? Did your feelings about it change over time in the way Dollard and Miller describe?
Defense Mechanisms Freud’s explanation Dollard and Miller Negative Reinforcement A reward that consists of the withdrawal of aversive stimuli
Defense Mechanisms Negative Reinforcement Any stopping of pain or anxiety is negatively reinforcing The behavior that occurred before such cessation will become more likely Put your hand in the fire!
Defense Mechanisms Dollard and Miller DM are cognitive behaviors that are negatively reinforced because they remove anxiety
Defense Mechanism Denial Repression Reaction Formation Projection Rationalization Intellectualization
Defense Mechanisms Freud vs. Dollard and Miller Freud was right . . . . Perhaps too complicated Principle of Parsimony

Rotter Behaviorism would predict you would go for the biggest reward However, your beliefs (i.e., expectancies) are also important! Expectancy Value Theory
Elements Behavior Potential (BP) The probability that you will perform the behavior in question Higher the BP, more likely you will do it!
Elements Expectancy (E) A persons belief about how likely a behavior will bring about a goal
Expectancy If you think so: If you do not think so: If you ask a person out will they say yes? If you think so: “Asking out” has high expectancy If you do not think so: “Asking out” has low expectancy
Expectancy It is a belief Objective odds matter less then subjective odds Lottery!
Questionnaire LC questionnaire
Expectancy General Expectancy Like a trait High GE (Internal locus of control) Energetic, highly motivated Low GE (External locus of control) Depressed, low motivation
Elements Reinforcement Value (RV) The subjective benefit of a reward How much do you really care about the outcome?
Reinforcement Value How much do you care about getting that date? How much do you care if you are rejected? How much do you care about doing school work instead? Note: RV is a relative term!
Putting it all together How do you predict BP?
Putting it all together How do you predict BP? Psychological Situation These values change as a result of the situation

Imagine High RV Low E What might happen?
John wants a date really bad! Doesn’t think he can get one.
Maladjustment Excessive time spent fantasizing Failure to develop social relationships Failure to develop social skills Self-fulfilling prophecy
Imagine Two behaviors have high RV? What might happen?
John wants to dedicate his life to the ladies! John wants to dedicate his life to police work!
Maladjustment Feel conflict Erratic and unpredictable behavior Neither may be accomplished
Therapy Focuses on the conscious and rational mind 1) What can you do? 2) What do you want? Importance of minimal goal level Importance of prioritizing desires
