Module 26: How We Learn and Classical Conditioning
How Do We Learn?
How Do We Learn? Learning Habituation Stimulus Associative learning Classical conditioning Operant conditioning Cognitive learning Observational learning
Learning the process of acquiring new and relatively enduring information or behaviors. Enables humans to be especially adaptable to our environments, perhaps our most outstanding trait as human beings.
Basic Forms of Learning Habituation- an organism’s decreasing response to a stimulus with repeated exposure to it. Habituation is NOT the same thing as sensory adaptation. Both involve a diminished response, but in the case of habituation, it is a form of learning, not a function of the sensory system. Essentially, through experience, you learn to react to a stimulus less.
Basic Forms of Learning Cognitive Learning- the acquisition of mental information, whether by observing events, by watching others, or through language. Ex. Observational Learning- learning by observing others. Also called social learning.
Basic Forms of Learning Continued Associative Learning- learning that certain events occur together. The events may be two stimuli (as in classical conditioning) or a response and its consequence (as in operant conditioning). Stimulus- any event or situation that evokes a response.
Conditioning Two Basic Forms Classical Conditioning- we learn to associate two stimuli and thus to anticipate events. Operant Conditioning- We learn to associate a response (our behavior) and its consequences, thus we (and other animals) learn to repeat acts followed by good results and avoid acts followed by bad results.

Classical Conditioning
Classical Conditioning Ivan Pavlov John B. Watson Behaviorism
Classical Conditioning a type of learning in which one learns to link two or more stimuli and anticipate events.* First explored, very famously, by Ivan Pavlov. https://www.youtube.com/watch?v=S6AYofQchoM http://www.discovery.com/tv-shows/head-games/videos/pavlovs-bell/ *the unconditioned response must be automatic.
Classical Conditioning Pavlov’s Experiments Ivan Pavlov
Classical Conditioning Pavlov’s Experiments Parts of Classical Conditioning Neutral Stimulus (NS) Unconditioned stimulus (US) Unconditioned response (UR) Conditioned stimulus (CS) Conditioned response (CR)
Parts of Classical Conditioning Neutral Stimulus (NS)- in classical conditioning, a stimulus that elicits no response before conditioning (NS). Unconditioned Stimulus (US)- in classical conditioning, a stimulus that unconditionally – naturally and automatically – triggers a response (UR). Unconditioned Response (UR)- in classical conditioning, an unlearned, naturally occurring response to the unconditioned stimulus (US), such as salivation when food is in the mouth. Conditioned Stimulus (CS)- in classical conditioning, an originally irrelevant stimulus that, after association with an unconditioned stimulus (US), comes to trigger a conditioned response (CR). Conditioned Response (CR)- in classical conditioning, a learned response to a previously neutral (but now conditioned) stimulus (CS).
Pavlov’s device for recording (a tube in the dog’s cheek collects saliva, which is measured in a cylinder outside the chamber).

Classical Conditioning Pavlov’s Experiments
Classical Conditioning Pavlov’s Experiments Pavlov presented a neutral stimulus (a tone) just before an unconditioned stimulus (food in mouth). The neutrals stimulus then became a conditioned stimulus, producing a conditioned response.

Classical Conditioning
Classical Conditioning Psychologist Michael Tirrell recalled that his first girlfriend loved onions, so he came to associate onion breath with kissing.
Typical Example: A mild electric shock is used to teach a rat to flex his forepaw when he hears a tone. US UR NS CS CR Shock Paw flex Tone Tone Paw flex
Office Example In the groundbreaking TV show, The Office, there is, allegedly, a famous example of classical conditioning. https://www.youtube.com/watch?v=9i2rlymfLbE Looking at it more closely, there are a few problems with this example. Why?
Office Example US Altoid? UR NS Hand extension CS CR Reboot sound? Is the Altoid really an Unconditioned Stimulus? Is the Hand extension really an Unconditioned Stimulus?
Classical Conditioning Acquisition Higher-order conditioning
Acquisition in classical conditioning, the initial stage, when one links a neutral stimulus and an unconditioned stimulus so that the neutral stimulus begins triggering the conditioned response. In operant conditioning, the strengthening of a reinforced response.
Higher Order Conditioning a procedure in which the conditioned stimulus in one conditioning experience is paired with a new neutral stimulus, creating a second (often weaker) conditioned stimulus. For example, an animal that has learned that a tone predicts food might then learn that a light predicts the tone and begin responding to the light alone. (Also called second-order conditioning.)
Classical Conditioning Extinction and Spontaneous Recovery The rising curve shows that the CR grows stronger as the NS is repeatedly paired with the US to become the CS (acquisition), then weakens as the CS is presented alone (extinction).
Extinction the diminishing of a conditioned response; occurs in classical conditioning when an unconditioned stimulus (US) does not follow a conditioned stimulus (CS); occurs in operant conditioning when a response is no longer reinforced.
Spontaneous Recovery the reappearance, after a pause, of an extinguished conditioned response.
Classical Conditioning Extinction and Spontaneous Recovery After a pause, the CR reappears (spontaneous recovery)
Classical Conditioning Generalization
Generalization the tendency, once a response has been conditioned, for stimuli similar to the conditioned stimulus to elicit similar responses. Ex. A dog conditioned to one tone, would also respond to a new and somewhat different tone. https://www.youtube.com/watch?v=UfE5HfQvQ-k
Classical Conditioning Discrimination
Discrimination in classical conditioning, the learned ability to distinguish between a conditioned stimulus and stimuli that do not signal an unconditioned stimulus. Ex. Guard dog vs guide dog.
Classical Conditioning Pavlov’s Legacy Classical conditioning applies to other organisms Showed how to study a topic scientifically
Pavlov Was a Huge Influence on Watson and Behaviorism John Watson used the ideas of Pavlov as a basis for his work, which is the foundation of behaviorism. Behaviorism- the view that psychology (1) should be an objective science that (2) studies behavior without reference to mental processes. Most research psychologists today agree with (1) but not with (2).

Module 27: Operant Conditioning
Operant Conditioning
Operant Conditioning Classical Conditioning Operant conditioning Respondent behavior Operant conditioning Actions associated with consequences Operant behavior
Operant Conditioning a type of learning in which behavior is strengthened if followed by a reinforcer or diminished if followed by a punisher. The focus is on using positive consequences to encourage the continuance of behavior, and negative consequences to encourage the avoidance of behavior. The underlying principle is what Thorndike called, the Law of Effect.
Skinner’s Experiments
Skinner’s Experiments Edward Thorndike’s Law of Effect B.F. Skinner Behavioral technology Behavior control
Law of Effect Thorndike’s principle that behaviors followed by favorable consequences become more likely, and that behaviors followed by unfavorable consequences become less likely. Edward L. Thorndike was a tremendous influence on psychology, and Behaviorism. Thorndike use a fish reward to entice cats to find their way out of a puzzle box. This would be a huge influence on B.F. Skinner.
B.F. Skinner B.F. Skinner used the ideas of Thorndike to develop his operant chamber, or Skinner box, in which he could measure the impact of reinforcement on behavior, without interference from outside sources.
Operant Chamber and Reinforcement Operant Chamber- in operant conditioning research, a chamber (also known as a Skinner Box) containing a bar or key that an animal can manipulate to obtain a food or water reinforcer; attached devices record the animal’s rate of bar pressing or key pecking. Reinforcement- in operant conditioning, any event that strengthens the behavior it follows.
Skinner’s Experiments Operant Chamber (Skinner Box) Reinforcement https://www.youtube.com/watch?v=yhvaSEJtOV8
Classical vs Operant https://www.youtube.com/watch?v=H6LEcM0E0io Classical Conditioning- we learn to associate two stimuli and thus to anticipate events. Operant Conditioning- We learn to associate a response (our behavior) and its consequences, thus we (and other animals) learn to repeat acts followed by good results and avoid acts followed by bad results.
Skinner’s Experiments Shaping Behavior Successive approximations Discriminative stimulus
Shaping an operant conditioning procedure in which reinforcers guide behavior toward closer and closer approximations of the desired behavior. By making rewards contingent on desired behaviors, researchers and animal trainers gradually shape complex behaviors.
Shaping and Perception Shaping can demonstrate how non-verbal organisms perceive. For example, when researchers can get a baby, or dog to respond to a particular stimulus and not to others, it demonstrates that the organism does recognize that particular stimulus. Discriminative Stimulus- in operant conditioning, a stimulus that elicits a response after association with reinforcement (in contrast to related stimuli not associated with reinforcement).
Positive vs Negative Reinforcement Positive Reinforcement- increasing behaviors by presenting positive reinforcers. A positive reinforcer is any stimulus that, when presented after a response, strengthens the response. Negative Reinforcement- increases behaviors by stopping or reducing negative stimuli, such as shock. A negative reinforcer is any stimulus that, when removed after a response, strengthens the response Note: negative reinforcement is NOT punishment.

Primary Reinforcer vs Conditioned Reinforcer Primary Reinforcer- an innately reinforcing stimulus, such as one that satisfies a biological need. -food, water, eliminating pain, etc. Conditioned Reinforcer- a stimulus that gains its reinforcing power through its association with a primary reinforcer; also known as a secondary reinforcer. -A pleasant tone of voice, a smile, money, good grades, etc.
Immediate vs Delayed Reinforcers Immediate reinforcers are those provided very soon after a desired act. Delayed reinforcers are those that do not come immediately. Animals typically need reinforcements that come within 30 seconds of the desired behavior for them to learn. An essential element of being human is the ability to delay reinforcement.
Conditioned reinforcer Immediate vs delayed reinforcers Skinner’s Experiments Types of Reinforcers: Primary and Secondary Reinforcers Primary reinforcer Conditioned reinforcer Secondary reinforcer Immediate vs delayed reinforcers
Skinner’s Experiments Reinforcement Schedules Continuous reinforcement-reinforcing the desired response every time it occurs. Reinforcement Schedule- a pattern that defines how often a desired response will be reinforced. Partial (intermittent) reinforcement- reinforcing a response only part of the time; results in slower acquisition of a response but much greater resistance to extinction than does continuous reinforcement. Fixed-ratio schedule- in operant conditioning, a reinforcement schedule that reinforces a response only after a specific number of responses. Variable-ratio schedule- in operant conditioning, a reinforcement schedule that reinforces a response after an unpredictable number of responses.
Reinforcement Schedules Continued Fixed-interval schedule- in operant conditioning, a reinforcement schedule that reinforces a response only after a specific time has elapsed. Variable-interval schedule- in operant conditioning, a reinforcement schedule that reinforces a response at unpredictable time intervals.

Previous Chart Skinner’s laboratory pigeons produced these response patterns to each of four reinforcement schedules (reinforcers are indicated by diagonal marks). For people, as for pigeons, reinforcement linked to number of responses (a ratio schedule) produces a higher response rate than reinforcement linked to amount of time elapsed (an interval schedule). But the predictability of the reward also matters. An unpredictable (variable) schedule produces more consistent responding than does a predictable (fixed) schedule.

Skinner’s Legacy
Skinner’s Legacy Controversies surrounding Skinner’s Operant Conditioning
Skinner’s Legacy B.F. Skinner insisted that outside forces shaped behavior, and encouraged using the methods of reinforcement to produce positive results. He believed reinforcement and punishment were already shaping behavior anyway, so why not control the process, and thus, shape behavior in a desirable way. Critics felt that Skinner ignored individuality and free-will, essentially stripping people of their humanity.
Module 28: Operant Conditioning’s Applications, and Comparison to Classical Conditioning
Application of Operant Conditioning
Application of Operant Conditioning At school- Quizlet, Socrative, candy. https://www.youtube.com/watch?v=jTH3ob1IRFo In sports- Starting with a task that is easier to accomplish, and working up. Superstitions, i.e. certain socks, batting box routine, etc. At work- Boss passing out praise, bonuses, little competitions, etc. Notice someone doing things right, and reinforce it). At home- Potty training, putting kids to bed, etc. For self improvement- getting your spouses to do things you want, conditioning yourself to study, or exercise, etc.
Keys to Using Conditioning State your goal measurable terms, and announce it. Monitor how often you engage in your desired behavior. Reinforce the desired behavior. Reduce the rewards gradually.
Biofeedback A system for electronically recording, amplifying, and feeding back information regarding a subtle physiological state, such as blood pressure or muscle tension. In the 1960’s, there was some research that made the possibilities of Biofeedback seem fantastic. As it turns out, research indicates that tension headaches are the most impacted by biofeedback.

Biological Constraints on Conditioning
Biological Constraints on Conditioning Limits on Classical Conditioning John Garcia (and Robert Koelling) Conditioned Taste Aversion: rats were exposed to a particular taste, sight, or sound, and then exposed to material that would make them sick. The rats would then become averse to the taste, but not the sight or sound. When the rats were sickened significantly later, they would still become taste averse. This is likely because the best way for the rat (or the human) to avoid eating toxic food, is to develop the sense of taste to discern the toxic nature, and then develop aversion to it. Biologically primed associations are associations that develop because we are predisposed toward them. An example of natural selection at work.
A tainted bit of sheep meat was intentionally left out for the wolves to find. When they became sick from the meat, they later avoided attacking sheep altogether

Biological Constraints on Conditioning Limits on Operant Conditioning We most readily learn and retain behaviors that reflect our biological predispositions, or put another way, biological constraints Predispose organisms to learn associations that are naturally adaptive. Ex. Horses
Cognition’s Influence on Conditioning
Cognition’s Influence on Conditioning Cognitive Processes and Classical Conditioning Cognitive processes, i.e.thoughts, perceptions, expectations can impact classical conditioning. Animals can learn the predictability of an event. Ex. Rats and Dogs get a shock after every tone, but will sometimes have a light precede the tone, the light is neutral. Latent Learning- learning that occurs but is not apparent until there is an incentive to demonstrate it. Cognitive Map- a mental representation of the layout of one’s environment. For example, after exploring a maze, rats act as if they have learned a cognitive map of it. Insight- a sudden realization problem’s solution. Intrinsic Motivation- a desire to perform a behavior effectively for its own sake. vs Extrinsic Motivation- a desire to perform a behavior to receive promised rewards or avoid threatened punishment.

Learning and Personal Control
Learning and Personal Control Cope Problem-focused coping Emotion-focused coping
Learning and Personal Control Cope- alleviating stress using emotional, cognitive, or behavioral methods. Problem Focused Coping- attempting to alleviate stress directly – by changing the stressor or the way we interact with that stressor. Emotion Focused Coping- attempting to alleviate stress by avoiding or ignoring a stressor and attending to emotional needs related to one’s stress reaction.
Learned Helplessness The hopelessness and passive resignation an animal or human learns when unable to avoid repeated aversive events. Ex. Dogs repeatedly given shocks with no way out, became cowardly and defeated later when facing a shock, but this time, having a path to escape. Dogs who had never been given a no way out scenario, quickly escaped every time. People who are repeatedly faced with traumatic events, over which they have no control, will often develop the learned helplessness. What are the social implications?

Mirrors and Imitation in the Brain
Mirrors and Imitation in the Brain Observational learning Social learning Modeling Bandura’s Bobo Doll Experiment
Learning by Observation Observational Learning- learning by observing others. Also called social learning. Modeling-the process of observing and imitating a specific behavior. Ex. Albert Bandura had kids draw a picture, while in a room with an adult working with tinker toys. The adult throws a temper tantrum, and beats up a large inflatable doll called Bobo. Later, when the children are confronted with adversity, they behaved in a strikingly similar way, when compared to children who had not been exposed.

Mirror Neurons frontal lobe neurons that some scientists believe fire when performing certain actions or when observing another doing so. The brain’s mirroring of another’s action may enable imitation and empathy. First observed in monkeys who had a sensor placed in their brains to show activity when they moved. When the monkey saw people moving, the sensor would show activity, even though the monkey did not move.
