Behaviorism
-Definition - objective study of behavior
-Goal - explain behavior without appealing to mentalistic notions
--"Discard all references to consciousness...
"
--Rejection of structuralism and functionalism
--Stimulus-response associationism
-Methodology
--Observation (with and without instruments)
--Animal models
The Scope of Watson's Influence
-Diminished human thinking
--Implicit behavior
-APA president 1916
-"Psychological Care of the Infant and Child"
--Environmentalism
--No emotional expressions were necessary - in fact, harmful
-Baby Albert
William McDougall
-Ardent supporter of free will and other mental ideas
--Instincts
--"Hormic" psychology
-A "Sane" behaviorist
-Classic debate with Watson in Washington D.C.
Edward Tolman
-Exposed to Munsterberg, Titchener, McDougall, and Koffka
-Started teaching at Northwestern then to UC Berkeley
-Used mentalistic notions to explain behavior
-Did not seek converts or disciples
-Resisted McCarthy-style loyalty pledge at Berkeley
Tolman's Contributions
-Rats and Mazes
-"Purposive Behavior in Animals and Men"
-Molar over molecular behavior
-Criticized "muscle-twitch" theory of thinking and speech
-Learning was more than a series of S-R links
-Learning vs performance
Tolman's Contributions cont.
-Cognitive view of maze learning
-Latent learning
-Learning cannot be reduced to mere motor responses
-Tolman and Honzik study
-Intervening variables
-Hypothesis testing model
-Place theory vs response theory
-Offered a major alternative to Hull's neo-behaviorism
Clark Hull
-Harsh early life
--Typhoid fever
--Polio
Hull's Contributions
-Psychology is a natural science
-All behavior could be broken down to S-R bonds
--Also used intervening variables, but not mentalistic ones
-Studied aptitude testing
-Studied hypnosis
--32 papers and a book "Hypnosis and Suggestibility: An Experimental Approach"
-Comprehensive deductive learning theory
-Model had four stages
--Independent variables
--Intervening variables (two stages)
--Dependent variables
-Strong mechanistic view of behavior
-Dominated research in 30's and 40's
B. F. Skinner
-Developed a "Skinner Box"
-Several disappointing business ventures
--Project pigeon
--Baby tender (or air crib)
--Teaching machines
Skinner's Contributions
-"The Behavior of Organisms"
-Introduced the term "operant" to differentiate between his and Pavlov's form of conditioning
-Introduced the concept "shaping"
-"Beyond Freedom and Dignity"
-Schedules of reinforcement
--Fixed vs variable (time between reinforcements)
--Ratio vs interval (# of responses between reinforcements)
-"Verbal Behavior"
--Speech comes from reinforcement
--Shattered by Noam Chomsky
Skinner's System
-Subject matter - behavior
--Insisted behaviorism did "consider events taking place in the private world within the skin"
--Method - experimentation
--Single-subject designs
-Research strategy
--Environmental control
--Non-statistical analysis of behavior
--Atheoretical - theories are harmful
Albert Bandura
-Social-Cognitive Theory
--Observational learning
--Bobo doll study
--Self-efficacy
Julian Rotter
-Social Learning Theory
--Cognitive form of behaviorism (more so than Bandura)
-Locus of Control
Radical vs Methodological Behaviorists
-Radical - Watson and Skinner
-Methodological - Hull(?), Tolman, Bandura, Rotter, and others
-Many today refer to themselves as behaviorists or cognitive/behaviorists
