-pacifist during WWI -rebel: opposed war when popular, opposed Watsonian behaviorism when popular
answer
Tolman
question
Gestalt theory and behaviorism -freer with terms than most behaviorists, but dealt with observable stimuli/overt responses
answer
Tolman's theory is a blend of
question
Unit of behavior-by being elementistic, the behaviorists were throwing away the baby with the bathwater -Molar behavior should be studied
answer
Main disagreement with behaviorists
question
Purposive, always directed toward some goal -Whole behavior patterns had a meaning that would be lost if studied from an elementistic viewpoint
answer

question
goal-directed behavior
answer
purposive behavior
Unlock the answer
question
-used to describe behavior, just as the terms slow, fast, correct, incorrect, etc. describe behavior -behavior will look "as if" its behavior is goal-directed or purposive, i.e. as long as the organism is seeking something in the environment

Organism learns what is there, gradually develops a picture of the environment that can be used to get around in it. -picture=cognitive map
answer
cognitive map
Unlock the answer
question
it is futile to look at individual responses -once the organism has developed a cognitive map, it can reach a particular goal from any number of directions
answer
Cognitive map concept vs behaviorists

question
the organism will choose the shortest route or the one requiring the least amount of work -similar to habit family hierarchy (Hull)
answer

question
unimportant as a learning variable, but there is some similarity between what Tolman called confirmation and what other behaviorists called reinforcement
answer
Reinforcement to Tolman
Unlock the answer
question
early tentative expectations -expectations are hunches about what leads to what -hypotheses that are confirmed are retained --> cognitive map develops
answer
hypotheses
Unlock the answer
question
learning that one event leads to another -a belief or hypothesis about the occurrence of a future event -an expectancy that is consistently confirmed develops into a means-end readiness
answer
expectancy
Unlock the answer
question
a belief -when an expectation is consistently confirmed, the organism ends up "believing" that if it acts in a certain way, a certain result will follow
answer
means-end readiness

question
similar to the notion of reinforcement, however, it does not have to involve overt behavior -when the prediction made about some future event is found to be accurate

question
Often, a rat pauses at a choice point and looks around as if thinking about the various alternatives available to it-pausing and looking around at the choice point. -different approaches are tested cognitively rather than behaviorally (one response tried, then another until solution)

question
3 groups of rats learning to solve a maze 1: never reinforced for correctly traversing the maze 2: always reinforced 3: reinforced on the 11th day
answer
Tolman and Honzik experiment with latent learning
Unlock the answer
question
1. Slight improvement in performance even in the group never receiving reinforcement 2. The reinforced group shows steady imporvement. 3. The third group reinforced on the 11th day performed even better than the consistently reinforced group

question
When animals are reinforced after a period of nonreinforcement, their performance very rapidly equals or exceeds that of animals that had been reinforced from the onset of the experiment.
answer
Conclusion of Tolman/Hoznik experiment

question
If an animal has learned an S-S expectancy and is given the opportunity to observe that that response will no longer lead to food, such observation will itself lead to extinction. i.e. rat learned to traverse maze to obtain food --> empty goal box: stop traversing maze
answer
Latent extinction

question
motivational factors -reinforcement provides an incentive for performing a response

question
Tolman maintained that animals learn WHERE things are, whereas S-R theorists maintained that specific responses are earned to specific stimuli

question
Two groups of rats Response Learning: Had to turn in same direction to be reinforced Place Learning: Had to be in same place to be reinforced

question
Place learners learned much faster. It was more "natural" for the animals to learn places than to learn specific responses.

when reinforcers were changed, behavior would be disrupted because a particular reinforcer becomes part of what is experienced

-attempted to make Tolman's terms more precise and his concepts more easily tested -describe Tolman's theory as S1-R1-S2 S1 elicits expectancy of some kind, R1 indicates the manner in which the expectancy is acted on, and S2 indicates what the organism thinks will happen as a result of its actions
