Types of Learning
Learning
…a systematic, relatively permanent change in
behavior that occurs through experience
Behaviorism
Associative Learning/Conditioning

Classical Conditioning:
Terminology

helps to explain involuntary behavior

unconditioned stimulus (UCS)

unconditioned response (UCR)

neutral stimulus (NS)

conditioned stimulus (CS)

conditioned response (CR)

Classical Conditioning:
Procedure

acquisition




UCS produces a UCR (reflex)
neutral stimulus (NS) paired with a UCS
after pairings, NS produces a CR
the NS has become a CS

contiguity – time between CS and UCS

contingency – is CS regularly followed by
the UCS?

Classical Conditioning: Pavlov

Unlearned/Reflexive



UCS – meat powder
UCR – dog salivates
NS – sound of Pavlov’s bell (prior to
pairings with meat powder)

Learned


CS – sound of Pavlov’s bell
CR – dog salivates

Classical Conditioning: Pavlov

Classical Conditioning

Generalization


CRs may appear after various NS that
are similar to the CS
Discrimination


CRs appear after the CS but not after
other CSs
discrimination generally learned by
presenting other CSs without the UCS

Classical Conditioning

Extinction



Spontaneous Recovery



CR is weakened by presenting the CS without the UCS
Pavlov rang the bell but did not present food, and the dog
stopped salivating
CR recurs after a time delay and without additional learning
when Pavlov rang the bell the next day, the dog salivated
Renewal

recovery of the CR when organism is placed in novel
context

Classical Conditioning

Classical Conditioning:
Applications

Phobias



Watson and Rayner (1920) – Little Albert
white rat (CS) paired with loud noise (UCS)
Counterconditioning



associate CS with new, incompatible CR
CS paired with new UCS
aversive conditioning

Classical Conditioning:
Applications





placebo effect
immune and endocrine responses
taste aversion
advertising
drug habituation

Operant Conditioning
 better at explaining voluntary behaviors
 the consequences of a behavior change
the probability of that behavior’s
occurrence
© 2011 The McGraw-Hill Companies, Inc.
Operant Conditioning
Thorndike’s Law of Effect

consequence strengthens or
weakens a S – R connection
B.F. Skinner


expanded on Thorndike’s work
shaping (reward approximations
of the desired behavior)

Reinforcement
Reinforcement increases behavior.
Positive Reinforcement


behavior followed by rewarding consequence
rewarding stimulus is “added”
Negative Reinforcement


behavior followed by rewarding consequence
aversive (unpleasant) stimulus is “removed”

Reinforcement
© 2011 The McGraw-Hill Companies, Inc.
Types of Reinforcers
Primary Reinforcers

innately satisfying
Secondary Reinforcers



become satisfying through experience
repeated association with a pre-existing
reinforcer
token economy

Schedules of Reinforcement
Generalization


stimulus “sets the occasion” for the response
responding occurs to similar stimuli
Discrimination

stimuli signal when behavior will or will not be
reinforced
Extinction and Spontaneous Recovery

behavior decreases when reinforcement stops
© 2011 The McGraw-Hill Companies, Inc.
Schedules of Reinforcement
Continuous Reinforcement
Partial Reinforcement




fixed
variable
ratio
interval
© 2011 The McGraw-Hill Companies, Inc.
Schedules of Reinforcement
Fixed Ratio (FR)

reinforcement follows a set # of
behaviors
Variable Ratio (VR)

reinforcement follows an
unpredictable # of behaviors
(e.g., an average)
© 2011 The McGraw-Hill Companies, Inc.
Schedules of Reinforcement
Fixed Interval (FI)

reinforcement follows behavior that occurs
after a set amount of time has elapsed
Variable Interval (VI)

reinforcement follows behavior that occurs
after an unpredictable amount of time has
elapsed

Punishment
Punishment decreases behavior.
Positive Punishment


behavior followed by aversive consequence
aversive (unpleasant) stimulus is “added”
Negative Punishment


behavior followed by aversive consequence
rewarding stimulus is “removed”

 immediate versus delayed reinforcement and
punishment
Applied Behavior Analysis

Observational Learning

learning that occurs when a person observes and
imitates behavior (modeling)

Albert Bandura – Social Cognitive Theory

four processes
- attention
- retention
- motor reproduction
- reinforcement

Cognitive Factors in Learning
Do cognitions matter?
Does learning involve more than
environment-behavior connections?
Purposive Behavior in Humans
- goal directed
- goal setting
- self-regulation and self-monitoring

Cognitive Factors in Learning

expectancy learning


latent learning/implicit learning

insight learning
