II. The Reaction to Watson’s Program

A. His major points

1. Psychology is the science of behavior

2. a purely objective experimental natural
science

3. both animal and human behavior are
studied
II. The Reaction to Watson’s Program

A. His major points

4. discard all mentalistic concepts & used
only behavior concepts (e.g., stimulus &
response)

5. Goal of psychology: prediction and
control of behavior
The Reaction to Watson’s Program

B. Initial reactions



1. behaviorism was not embraced
2. his 1919 book provided the movement’s impact
C. Calkins: adhered to introspection as the sole
method for some processes


D. Washburn: called Watson an enemy of
psychology
The Reaction to Watson’s Program

E. 1920s

1. university offered courses in behaviorism


2. the word "behaviorist" appeared in journals

3. McDougall: against behaviorism publicly


4. Titchener: complained of its force and extent

5. Other forms of behaviorism have developed
III. The Methods of Behaviorism

A. Psychology must restrict itself to the
objective study of behavior.

B. Adoption of the methods of the natural
sciences
 1. observation, with and without instruments
 2. testing methods
 3. verbal report method
 4. conditioned reflex method
The Methods of Behaviorism

C. Observation:


a necessary basis for the other methods
D. Testing methods


Were already in use
But Watson thought that test results are samples
of behavior, not indices of mental qualities
The Methods of Behaviorism

D. Verbal reports

1. A controversial issue


2. speech reactions are objectively observable


3. thinking is speaking silently


4. admitted the lack of precision and limitations


5. limited it to situations where it could be verified
The Methods of Behaviorism

D. Conditioned reflex method

1. adopted in 1915

2. Watson responsible for widespread use


3. conditioning is stimulus substitution


4. selected as an objective method of behavior
analysis
The Methods of Behaviorism

5. Reinforced the concept of people as
machines.

6. human subject: the observed rather than the
observer
 a. designation changed from "observer" to
"subject“
 b. experimenter became the observer
IV. The Subject Matter of Behaviorism

A. Elements of behavior


1. The primary subject matter of behaviorism
was the elements of behavior
2. goal: understand the organism’s total
behavior
The Subject Matter of Behaviorism

2. explicit versus implicit

a. Responses can be explicit or implicit

b. explicit responses: overt and observable


c. implicit responses: occur inside of the organism
(e.g., nerve impulses)
 1) observable
 2) must be observable through the use of
instruments
The Subject Matter of Behaviorism

3. simple versus complex stimuli



a. Stimuli may be simple or complex
B. stimulus situation can be reduced to specific
component stimuli
4. laws of behavior


a. specific behavior can be analyzing the S-R
complexes into their elementary S-R units.
b. all areas of behavior must be considered as
objective S-R events
The Subject Matter of Behaviorism

B. Instincts


1. 1914: Watson described 11 instincts
2. 1925: eliminated the concept of instinct
 a. an extreme environmentalist
 b. denied inherited capacities, temperaments,
talents
 c. children can become anything one desires
 d. this viewpoint became popular in America
society
The Subject Matter of Behaviorism

C. Emotions

1. Emotion was physiological responses to
specific stimuli


E.g., threatening (Stimuli)  produces internal
physical changes such as rapid heart rate (response).
2. Denied any conscious perception of emotion
or sensations from internal organs
The Subject Matter of Behaviorism

C. Emotions



3. Emotion is a form of implicit behavior:
internal responses are evident in physiology
(e.g., pulse rate)
4. Criticized James’s theory of emotion
5. fear, love, and rage are 3 innate emotional
responses
The Subject Matter of Behaviorism

D. Albert, Peter, and the rabbits
 1. the Albert study never
successfully replicated

2. Mary Cover Jones
 a. study of Peter
 b. generalized fear responses
eliminated
 c. Later: modern systematic
desensitization techniques.
The Subject Matter of Behaviorism

E. Thought processes

1. Watson attempted to reduce thinking to
implicit motor behavior
 a. Thought was a type of sensorimotor
behavior.
 b. The behavior of thinking must involve
implicit speech reactions or movements
 c. reduced thinking to subvocal talking
The Subject Matter of Behaviorism

2. Thinking is a way of talking silently.

3. We also express thought through gestures
(e.g., frowns), which are overt reactions to
stimuli
V. Behaviorism’s Popular Appeal

A. Watson called for a society based on
scientifically shaped and controlled behavior

B. Emphasis on childhood environment and
minimization of heredity (Hope to public)
Behaviorism’s Popular Appeal

C. Conditioned reflex experiments



(e.g., Albert study)
1. implied emotional disturbances in adulthood
due to conditioned responses during earlier years
2. implies proper childhood conditioning should
prevent adult disorders
D. Experimental ethics


1. a framework for research
2. elaborated by Skinner
VIII. Criticism of Watson’s Behaviorism

A. McDougall against Watson’s view

a. agreed data of behavior are a proper focus for
psychology

b. argued data of consciousness also necessary



c. questioned Watson's view that human behavior is
fully determined; left no room for free will
d. critical of Watson’s use of the verbal report method
IX. Contributions of Watson’s Behaviorism

A. Made psychology more objective in methods
and terminology

B. Stimulated a great deal of research


C. Effectively overcame the earlier positions in
psychology

D. Objective methods and language became part
of the mainstream
