Clark Hull
The spirit of mechanism
omitted mentalistic terms, including consciousness and purpose
used mechanistic terms
human behavior
mechanistic, robotic
automatic
reducible to the language of physics
machines could be constructed that would display human cognitive functions
Clark Hull
Objective methodology & quantification
objective experimental methods
quantitative
laws of behavior expressed in language of mathematics
equations
empirical constants
theorems and corollaries
Clark Hull
objective definitions
rigorous deduction
four methods
simple observation
systematic controlled observation
experimental testing of hypotheses
the hypothetico-deductive method
establish postulates
deduce experimentally testable hypotheses
submit them to experimental test
method necessary for psychology to be a science
Clark Hull
Drives
motivation
a state of bodily need
arises from a deviation from optimal biological conditions
drive
an intervening variable
a stimulus arising from a state of tissue need
arouses or activates the behavior
Clark Hull
its strength is empirically determined
is nonspecific
energizes behavior
does not direct behavior
direction of behavior determined by environmental stimuli
reinforcement: reduction or satisfaction of a drive
Clark Hull
primary drives
arise from a state of physical need
are vital to the organism’s survival
secondary
