  • 3rd side (hint)
Who is Clark Leonard Hull?
What was Hull's approach to theory?
Basic features of much modern psychological research (e.g., Hypothetical/Deductive theory)
Postulates (“first principles”)
Theorems and hypotheses deduced from postulates (actually tested)
There are three
What is the Drive Reduction Theory?
Behavior occurs in response to "drives" such as hunger, thirst, sexual interest, feeling cold, etc.
When the goal of the drive is attained (food, water, mating, warmth) the drive is reduced, at least temporarily.
Reduction of drive serves as a reinforcer for learning.
What did Hull not include in his theoritical construsts?
Unobservable congnative aspects
When was Hull's original theory? And when was it revised?
1943, and 1952
40's and 50's
What is a stimulus trace?
neutral impulse
What does a neutral response generate?
And overt response (S-R top S-s-r-R)
What is Habitat Strength (sHr)?
Early reinforced pairings have more effect on learning (habit strength) than later ones
What is reaction potential, sEr?
a function of Drive and Habit Strength
Reaction potential = SER = SHR x D
When either SHR or D are zero, then SER is zero
What is reactive inhibition (IR)?
Reactive inhibition (IR) =muscular fatigue related to task difficulty
What is Effective Reaction Potential?
Effective React. Poten.=SER = SHR x D – (IR + SIR)
What is the oscillation effect, SOR?
Momentary effective reaction potential = [SER =[SHR x D – (IR + SIR)] – SOR
What is sLr?
Reaction Threshold
