PSYCH 104 Final (Learning: Operant conditioning) Flashcards
(29 cards)
Respondent conditioning function and controlling event?
Function: behavior is elicited by a stimulus
Controlling event: stimuli preceding response
Operant conditioning function and controlling event?
Function: behavior is emitted to produce/remove a stimulus
Controlling event: Stimuli following the response
Operant conditioning (Definition)
The study of how consequences effect behavior
Operant conditioning chambers (What are they designed to do?)
- Operant conditioning chambers
○ Designed to exhibit maximum control over all variables
What does a reinforcer result in?
Increased behavior = reinforced
What does a punishment result in?
Decreased behavior = punish
What are the 5 effects of reinforcers?
Effect of reinforcing consequences
- Increase frequency
- Increase duration
- Increase intensity
- Increase in quickness
- Increase in variability
Two ways of reinforcing (What are they?)
Two ways of reinforcing
- Add a stimulus + positive reinforcement
- Remove a stimulus - negative reinforcement
What is important to remember about Rewards?
Reward (does not always =) reinforcer
- (if you give a dog a treat for rolling over that does not mean he will do it again)
Learning (Operant conditioning: reinforcement)
- Reinforcement:
○ The procedure of providing consequences for a behavior that increase or maintain the probability of that behavior occuring in the future
Learning (Operant conditioning: reinforcer)
- Reinforcer:
○ any event or stimulus that follows an operant response and increases or maintains its future
Learning (Operant conditioning: Positive reinforcement)
- Positive reinforcement:
○ Any event or stimulus that, when presented as a consequence of a behavior, increases or maintains the future probability of that behavior
Learning (Operant conditioning: negative reinforcement)
- Negative reinforcement:
○ Any event or stimulus that, when removed as a consequence of a behavior, increases or maintains the future probability of that behavior
Two ways of punishing (What are they?)
Two ways of punishing
- Add a stimulus + positive punishment
- Remove a stimulus - negative punishment
What are punishments defined by?
- Punishment
○ Punishers are defined by their effect on behavior
§ If the behavior doesn’t decrease the behavior its not a punishment
○ Can be highly effective and work over the long term when used properly
○ Drawbacks (this list is not exhaustive):
§ Only decreases behavior (it doesn’t teach new acceptable behaviors)
§ Will usually foster undesirable emotional responses
□ Aggression
□ Fear and anxiety responses
□ Crying
□ Apathy and/or depression
§ Can foster subversive practices to escape punishment
§ Limitation of the punisher
What does punishment have to do in order to be one?
(it has to actually elicit a change in the probability of occurrence to actually be a punishment)
Operant conditioning (Discriminative stimulus)
Discriminative stimulus
- A stimulus or event that sets the occasion for reinforcement
○ Example: signals that a behavior will be reinforced when it occurs
Operant conditioning (Discrimination)
Discrimination:
- The effect of response being more likely to occur in the Prescence of the discriminative stimulus or event than its absense
○ Example: the rat is more likely to press the lever when the light is on than when it is off
§ The light is said to be “controlling” the rats behavior
Three term contingency (What is it?)
- The discriminative stimulus
- The behavior
- The reinforcer
Operant conditioning (Operant/stimulus generalization)
- Operant/stimulus generalization:
○ When an organism responds to values of the discriminative stimulus that are different than the originally trained values
§ Produces a generalization gradient
Operant conditioning (Generalization gradients)
- Generalization gradients: a description about how much control a stimulus has over behavior
○ Discrimination = only one stimulus is likely
○ Generalization = several stimulus may be present
Operant conditioning (operant extinction)
- Operant extinction:
○ The procedure of withholding reinforcers that maintain a behavior
Operant conditioning (Spontaneous recovery)
- Spontaneous recovery:
○ The tendancy for extinguished behavior to occur again in situations similar to those it had been previously reinforced after time has elapsed
○ Repeated sessions of extinction (usually in multiple settings) are required to prevent spontaneous recovery
§ Demonstrates that extinction is not simply “forgetting” what was learnt
Operant conditioning (Excitation bursts)
- Excitation bursts:
○ Short lived rapid burst in responding following the initial exposure to extinction- Extinction also produces
○ Aggression
○ Variability of responding
- Extinction also produces
