Unit Five Flashcards
Stimulus discrimination
A processes in which a response becomes apt to occur in one stimulus but not in others because of reinforcement of the response in that stimulus situation but not in others
Discriminative stimulus Sd or S+
A stimulus for which a response is apt to occur owing to reinforcement of the response of the presence of that stimulus
S delta or S-
A stimulus for which a response is not apt to occur because no reinforcers follow the response when the stimulus is present
Excitatory Stimulus control
Exists when a response is more likely to occur in the presence of s stimulus than in the absence of the stimulus
Inhibitory stimulus control
A response is more likely to occur in the absence of a stimulus than in the presence of a stimulus
Exciting stimulus generalization
A process in which a response reinforced in one stimulus situation becomes apt to occur in different although similar stimulus situation
Inhibitory stimulus
A process in which a response extinguished in one stimulus situation becomes less spot to occur in a different though similar stimulus situation
Response generalization
Aka response induction occurs when reinforcing one class of responses results in s strengthening of similar responses outside the reinforced class
Discrimination definition
The tendency to behave differently in different situations
Generalization definition
Ex
Learned behavior to spread to situations not involved in training
The conditional response spreads or generalizes to stimuli somewhat different from the CS
Alberta fear of white rats spread to other white furry objects
Thorndike study with generalization
Dog learned to escape s box by pulling on s loop. Then put in s new box with loop in a different location and learned it faster, then put into new box with it higher and learned that faster .
The more experiences the animal has escaping boxes the more quickly it learned to escape from new boxes
Learned industriousness
High level of effort on one task increases the level of effort on other tasks
One way to increase generalization
Provide training and practice in a wide variety of settings
Study that showed that generalization can work against teschers and their students
Teacher first gave children unsolvable problems. Later gave them new solvable problems and they failed to solve them. When a new teacher gave the same problems they were able to solve them
Another issue with generalization
Problem behaviors can generalize to other situations
Similarity and generalization when plotted called
The more similar a novel stimulus is to training the more likely that the participant is to behave as though they were the training stimulus
When plotted they are called s generalization gradient
A generalization gradient shows what
The tendency of s behavior to occur in situations that differ systematically from the training situation/stimulus
Why are fire drills sometimes not effective to prepare for s real fire
A building on fire presents a very different situation from a building that is not on fire
The razan study involved what kind of training procedure
Pavlovian
Racial prejudice probably involves
Semantic generalization
In operant discrimination training the stimulus that indicates the more reinforcing consequence of a behavior is designated
S+
In errorless discrimination training how is the s- presented
Weak form and gradually faded in
The doe implies discrimination training vs. be improved how
By providing different outcomes for different behaviors
Marlatts work suggests that drug abuse is partly due to
Stimulus control
How is pavlovs explanation of discrimination and generalization circular
He infers the physiological events from observations about generalization and discrimination and then explains the two by using the physiological events
Suppose Hanson has used a disk of 530 nm as the s- . Where would the peak of the responding have occurred
Shifted in the opposite direction possibly to 560nm
