Classical Conditioning
Generalization
◦ Conditioned responses can occur in response to
stimuli similar to the conditioned stimulus
Discrimination
◦ Learning to tell the difference between different
stimuli, responding only to the conditioned stimulus
and not to similar stimuli

Classical Conditioning
Extinction
◦ When the pairing of the conditioned and
unconditioned stimulus stops
◦ Gradual decrease in the response to the conditioned
stimulus

emotional aspects of personality
◦ neurotic behavior
◦ phobias
◦ superstitious behavior
◦ etc.

The Radical Behaviorism of
B. F. Skinner Personality IS a group of responses to the
environment
Radical determinism
◦ All behavior is caused
Operant Conditioning
◦ Behavior is changed by its consequences
◦ “Skinner box” (operant chamber)

Operant Conditioning
The status of a consequence as reinforcement or
punishment is empirically determined
◦ If the preceding response increases after the consequence
occurs, it is a reinforcement
◦ If the preceding response decreases after the consequence
occurs, it is a punishment
Reinforcement or punishment can occur through
adding or removing a stimulus
◦ For rats: food, noise, electric shock
◦ For humans: money, praise, hugs, candy, chores, spanking,
prison

Skinner’s Walden Two
Applied the principles of operant conditioning to design a society
Sets up a controlling environment by using positive reinforcement
Several communities were founded on behaviorist principles

Modern Behaviorist Approaches
to Personality Behaviorism’s limitation to observable behavior is
inconsistent with the focus of most personality
approaches
Reinforcement Sensitivity Theory connects individual
differences in the nervous system to the response to
reward versus punishment
◦ Reward works through Behavioral Activation System (Behavioral
Approach System)
◦ Punishment works through Behavioral Inhibition System
Act Frequency Approach as a way to connect
observable actions to traits

Timeline: The Behaviorist and
Learning Approach
Behaviorist and Learning Aspects
Societal and Scientific Context
Philosophers and theologians view individual deviations as games of the gods or possession by the devil
Ancient times and Middle Ages
Humans are seen primarily in religious terms, as created by a divine presence
Individual is increasingly understood to be shaped by social class and by work (Locke’s tabula rasa)
1700s -1800s
Increasing emphasis on reason and rationality, philosophers search for the core of human nature

Behaviorist and Learning Aspects
Societal and Scientific Context
Pavlov studies classical conditioning; other studies of animal learning begin in earnest
1880s-1900s
Darwin’s evolutionary approach leads to experimental studies in animals in search of universals applicable to people
Watson founds behaviorism
1900-1920
Experimental psychology develops; increased industrialization of society

Societal and Scientific Context
Skinner dramatically expands behaviorism; Hull develops broader learning theory
1920s-1940s
Experimental psychology is increasingly dominated by behaviorism; attempts to combine behaviorism and psychoanalysis
Influence of social psychology increases; child rearing practices are studied
1940s-1950s
In reaction to world war, studies of propaganda and attitude-formation increase

Timeline: The Behaviorist and
Learning Approach
Behaviorist and Learning Aspects
Societal and Scientific Context
Existentialists challenge behaviorists; cognitive psychology grows; behaviorism declines
1950s-1960s
Economic boom with huge new middle class; new affluence removes old fears from workers
Learning approaches increasingly combined with cognitive and social approaches; personality seen as interacting with the demands of social situations
1970s-1980s
Societal problems of crime, delinquency lead to searches for more sophisticated models of teaching and learning

Advantages

◦ Looks for general laws that apply to all organisms
◦ Forces attention to the environmental influences on
behavior

Limits
◦ Ignores insights and advances from cognitive and
social psychology
◦ May tend to dehumanize unique human potentials
◦ Explains all differences between individuals as a
consequence of their reinforcement histories
◦ Views humans as objects to be trained

Implications for therapy
◦ Since personality is conditioned and learned, therapy
is based on teaching desirable habits and behaviors,
and on extinguishing undesirable ones
