Learning vs. Instincts
Learning
A process through which experience produces lasting change in behavior or mental processes

Habituation
Learning not to respond to repeated presentation of a stimulus

Instincts
Motivated behaviors that have a strong innate basis

Copyright © 2012 Pearson Education, Inc. All rights reserved.
Behavioral Learning
Forms of learning that can be described in terms of stimuli and responses (e.g., classical and operant conditioning)

Learning
Mere Exposure Effect
Learned preference for stimuli to which we have been previously exposed

Classical conditioning is 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.

Key Question 4.1: What sort of learning does classical conditioning explain?

Copyright © 2012 Pearson Education, Inc. All rights reserved.
Classical Conditioning
Neutral Stimulus
Any stimulus that produces no conditioned response prior to learning

Acquisition
Initial learning stage in classical conditioning
Conditioned response (CR) becomes elicited by the conditioned stimulus (CS)

Figure 4.1 Basic Features of Classical Conditioning
Before conditioning, the food (UCS) naturally elicits salivation (UCR). A tone from a tuning fork is a neutral stimulus (NS) and has no effect. During conditioning (the acquisition phase), the tone (NS) is paired with the food (UCS), which continues to elicit the salivation response (UCR). Through its association with the food, the previously neutral tone becomes a conditioned stimulus (CS), gradually producing a stronger and stronger salivation response (CR).

Biological Predispositions:
A Challenge to Pavlov
Conditioned aversions involve both nature and nurture.
Garcia & Koelling (1966):
Selective CS-UCS connection
Innate disposition to associations

Why are some stimuli-consequence combinations readily learned while other combinations are highly resistant to learning?
What any organism can or cannot learn in a given setting is due in part to its genetic preparedness.

In operant conditioning, the consequences of behavior—such as rewards and punishments—influence the probability that the behavior will occur again.

*
Key Question 4.2: How do we learn new behaviors by operant conditioning?

Copyright © 2012 Pearson Education, Inc. All rights reserved.
How Do We Learn
New Behaviors by
Operant Conditioning?
Operant Conditioning
Learning in which the probability of a response or changed by its consequences—that is, by the stimuli that follow the response

Copyright © 2012 Pearson Education, Inc. All rights reserved.
How Do We Learn
New Behaviors by
Operant Conditioning?
Law of Effect
Responses that produced desirable results would be learned or “stamped” into the organism.

Reinforcer
Condition (involving either the presentation or removal of a stimulus) that occurs after a response and strengthens that response

Copyright © 2012 Pearson Education, Inc. All rights reserved.
Skinner’s Radical Behaviorism
B.F. Skinner believed that the most powerful influences on behavior are its consequences.
“The power of reinforcement”
Operant Chamber
Barlike apparatus that delivers reinforcers and punishers contingent on an animal’s behavior

Copyright © 2012 Pearson Education, Inc. All rights reserved.
The Power of Reinforcement
Positive Reinforcers
Stimulus presented after a response; increases the probability of that response happening again
Positive = add or apply

Negative Reinforcers
Removal of an unpleasant stimulus; increases the probability of that response happening again
Negative = subtract or remove

Varying the timing and frequency of reinforcement
Continuous Reinforcement
Reinforcement schedule in which all correct responses are reinforced

Intermittent (Partial) Reinforcement
Reinforcement schedule in which some, but not all, correct responses are reinforced

Copyright © 2012 Pearson Education, Inc. All rights reserved.
Schedules of Reinforcement
Ratio Schedules
Reinforcement depends on the number of correct responses.

Interval Schedules
Reinforcement depends on the time interval elapsed since the last reinforcement.

Fixed Ratio (FR)
Fixed Interval (FI)
Variable Ratio (VR)
Variable Interval (VI)

Schedules of Reinforcement
Fixed Ratio (FR)
Fixed Interval (FI)
Variable Ratio (VR)
Variable Interval (VI)
Reinforcement is contingent on a certain, unchanging number of responses.
e.g., factory workers getting paid after every ten cases of product are completed

Schedules of Reinforcement
Fixed Ratio (FR)
Fixed Interval (FI)
Variable Ratio (VR)
Variable Interval (VI)
Reinforcement presented after a certain number of responses, but that number varies from trial to trial
e.g., slot machine pay-offs

Copyright © 2012 Pearson Education, Inc. All rights reserved.
Schedules of Reinforcement
Fixed Ratio (FR)
Fixed Interval (FI)
Variable Ratio (VR)
Variable Interval (VI)
reinforcement presented after a certain fixed amount of time, regardless of number of responses
e.g., weekly or monthly paychecks

Copyright © 2012 Pearson Education, Inc. All rights reserved.
Schedules of Reinforcement
Fixed Ratio (FR)
Fixed Interval (FI)
Variable Ratio (VR)
Variable Interval (VI)
Reinforcement presented after a certain amount of time, but that amount varies from trial to trial
e.g., random visits from the boss, who delivers praise

Patterns of Responding

The Power of Reinforcement
Primary Reinforcers
Reinforcers that fulfill basic biological needs or desires, such as food and sex, that have an innate value to an organism

Copyright © 2012 Pearson Education, Inc. All rights reserved.
The Power of Reinforcement
Secondary (Conditioned) Reinforcers
Stimuli, such as money or tokens, that acquire their reinforcing power by their learned association with primary reinforcers

Copyright © 2012 Pearson Education, Inc. All rights reserved.
Factors that Can Influence
the Effectiveness of Reinforcement
Instinctive Drift
Innate response tendencies interfere with learned behaviors; innate tendencies can override behaviors learned through reinforcement
E.g., attempting to train your cat to not scratch the furniture

Premack Principle-
A preferred activity can reinforce a less preferred activity
E.g., children sitting quietly in class in order to go out for recess

Copyright © 2012 Pearson Education, Inc. All rights reserved.
Punishment
Punishment
An aversive consequence that diminishes the strength of the response it follows

How does this differ from negative reinforcement?

Negative Punishment
Removal (-) of an attractive stimulus after a response

Both attempt to decrease the likelihood
that a behavior will reoccur.

Four Kinds of Consequences
STIMULUS
Table 4.1 Four Kinds of Consequences
Three important points to keep in mind as you study this table:
1. “Positive” and “negative” mean that a stimulus (consequence) has been added (presented) or subtracted (removed). These terms have nothing to do with “good” or “bad, pleasurable or painful.”
2. We can often predict what effect a particular consequence will have, but the only way to know for sure whether it will be a reinforcer or a punisher is to observe its effect on behavior. For example, although we might guess that a spanking would punish a child, the attention might actually serve as a reinforcer to strengthen the unwanted behavior.
3. From a cognitive viewpoint, we can see that reinforcement consists of the presentation of a pleasant stimulus or the removal of an unpleasant one. Similarly, punishment entails the presentation of an unpleasant stimulus or the removal of a pleasant one.

Copyright © 2012 Pearson Education, Inc. All rights reserved.
When Does Punishment Work?
When presented without delay
When consistent
When limited in duration and intensity
When the consequence is logical
When limited to the specific situation at hand
When no mixed messages are sent
When negative punishment is used

Copyright © 2012 Pearson Education, Inc. All rights reserved.
Uses and Abuses of Punishment
Problems associated with punishment:
Power of use usually disappears when threat of punishment is removed
Rewards can override/overpower the punishment
Often triggers escape or aggression
Teaches legitimate use of aggression to influence others
May inhibit learning new and better responses
Is often applied unequally

Positive reinforcement
encourage desirable behaviors
Punishment
use logical consequences, swiftly, without undue harm
Negative reinforcement
Extinction
control all possible reinforcers

According to cognitive psychology, some forms of learning must be explained as changes in mental processes rather than as changes in behavior alone.
