John B. Watson (1878-1958)
• Founded behaviorism (did not originate it)
• His efforts are a crystallization of the ideas
already emerging within psychology
• Distinction between Watson and his
predecessors:
• Watson announced an intentional goal
of founding a new school
John B. Watson (1878-1958)
The Development of Behaviorism
•
Watson:
• 1903-1908: Instructor, at University of Chicago
• Psychic or mental concepts have no value for a science of psychology
• Official launch of behaviorism: Psychology as the Behaviorist Views it.
Psychological Review (Watson, 1913)
• Argued for the acceptance of animal psychology and described the
advantages of using animal subjects in psychological research
• Wanted behaviorism to be of practical value; applied to the real world as
well
The Reaction to Watson’s Program
Major points of Watson’s Psychology:
•
Psychology is the science of behavior
•
Rejected the introspective method
•
Use of animals
Psychologists should discard all mentalists ideas and use only behavior concepts such
as stimulus and response
• Psychology’s goal is to predict and control behavior
•
•
Watson’s program was not embraced immediately or universally
•
•
Critics questioned his rejection of introspection
By the 1920s:
• Universities were offering courses in behaviorism
• Term was becoming acceptable in the professional journals
The Methods of Behaviorism
•
Watson insisted that psychology restrict itself to the data of
the natural sciences (what could be observed)
•
Methods:
• Observation with and without the use of instruments
• Testing methods
• The verbal report method
• The conditioned reflex method
•
New methods = change in the nature and role of the human subject
in the psychology laboratory
•
•
•
Subjects no longer responsible for the observing
Role of experimenter is now more important than the subject
Subjects merely behaved: reinforced the view of people as machines
The Subject Matter of Behaviorism
•
Focus on elements of behavior: body’s muscular movements and glandular secretions
•
Psychology would deal only with acts that could be described objectively, without using
subjective or mentalistic terminology
•
Four types of behavior
•
Explicit (overt) learned behavior
• talking, writing, etc.
•
Implicit (covert) learned behavior
• increased heart rate caused by a feared stimulus
•
Explicit unlearned behavior
• grasping, blinking, sneezing, etc.
•
Implicit learned behavior
• glandular secretions
•
Underlying belief: all areas of behavior would be considered in objective S-R terms
Instincts
•
1914, Watson accepted the role of
instincts in behavior
•
1925: Watson revised his position and
eliminated the concept of instinct
• Refused to admit to his system any
inherited capacities, temperaments, or
talents of any kind
• Behaviors that seemed inherited were
traced to early childhood training
• Optimistic viewpoint: children could be
trained to be whatever one wanted
them to be
Emotions
•
Emotions: physiological responses to specific
stimuli
• Physical manifestations: blushing, perspiration,
increased pulse rate
• Denies any conscious perception of the emotion
or the sensations from the internal organs
•
Three primary unlearned emotions:
• Fear-produced by loud noises and loss of support
• Rage-restriction of bodily movements
• Love-rocking, patting, caressing
Thought Processes
•
Watson: thought processes occur in the absence
of muscular movements
• They are not accessible to observation and
experimentation
• Attempted to reduce thinking to implicit motor
behavior
• Reduced thinking to sub-vocal talking that relies
on the same muscular habits we learn for overt
speech
On Childrearing Practices
Psychological Care of the Infant (1928)
The Psychologist, the Baby, and the Hammer:
Don’t Try This at Home!
•
“Little Albert” study:
• John Watson and Rosalie Rayner conducted experiments
to test learning
• A child is distracted while Watson strikes a steel rod with a
hammer
• The child reacts violently and begins crying
• Once the hammer strike is paired with previously neutral
stimuli (white rat), the stimuli begins to elicit fear response
•
Watson’s conditioning works when associations are made
between stimuli and response
• Fear generalized to other fuzzy objects (e.g., dog, fur coat,
Santa Claus mask)
Little Albert
•
Conclusion: adult fears, anxieties, and phobias are conditioned emotional
responses that were established in infancy and childhood and stay with us
throughout our lives

Albert, Peter, and the Rabbits
•
Conditioning of little Albert leads Watson to reject the
notion of the unconscious because it could not be
objectively observed
•
Mary Cover Jones: conducts a study with three-yearold Peter, who already showed a fear of rabbits
•
The rabbit cage was placed at a distance
•
Each day the cage was moved closer to Peter
• Successfully eliminates the fear response through
counter conditioning
• Precursor to behavioral therapy
Behaviorism’s Popular Appeal
•
Reasons for popularity of behaviorism
• Possibility of controlled behavior; free of myths, customs, and
conventional behaviors
• Studies provide evidence that all undesirable behaviors can be
eliminated, especially in childhood
• Theory does not blame individual for negative behaviors
• Replace religion-based ethics with experimental ethics
An Outbreak of Psychology
•
1920s, following behaviorism’s announcement:
• General public was convinced that psychology
provided the path to health, happiness, and
prosperity
• Practical topics: curing the blues, the psychology
of crooks, fears and worries, the meaning of IQ
scores, inferiority complexes, family conflicts, and
why we drink coffee
• Teaches the public how to explore one’s mind
Criticisms of Watson’s Behaviorism
•
Criticized because system:
• Proposes sweeping revision
• Blatantly attacks the existing order
• Suggests that the earlier version of
the truth be discarded
• Is said to have omitted important
components (e.g., sensory and
perceptual processes)
Criticisms of Watson’s Behaviorism
(cont’d.)
•
Karl Lashley (1890-1958):
• Former advocate of Watson’s behaviorism
• Two famous principles:
• Law of mass action
• Principle of equipotentiality
•
William McDougall (1871-1938):
• Forceful opponent of Watson
• Known for his instinct theory of behavior: suggests there are innate tendencies
to thought and action
Contributions of Watson’s Behaviorism
•
An effective agent of the Zeitgeist
•
More objective in methods and terminology
•
Overcame earlier positions in psychology
•
Strong conceptual base for modern psychology
•
Watsonian behaviorism was replaced by other forms of psychological objectivism
that built on it
