A schedule determining how often reinforcement is delivered in an operant conditioning paradigm | What is a reinforcement schedule? |
A type of operant conditioning in which the response causes a einforcer to be 'added' to the environment; over time, the response becomes more frequent | Define positive reinforcement |
A type of operant conditioning in which the response causes a punisher to be 'added' to the environment; over time, the response becomes less frequent | Define positive punishment |
A type of operant conditioning in which the response causes a punisher to be taken away or 'subtracted from' the environment; over time, the response becomes more frequent | Define negative reinforcement |
A type of operant conditioning in which the response causes a reinforcer to be taken away or 'subtracted from the environment; over time, the response becomes less frequent | Define negative punishment |
Clean room -> get weekly allowance (reinforcement). Tease little sister -> receive parental scolding (punishment) | Positive example: |
Take aspirin -> headache goes away (reinforcement). Fight with other children -> time-out from play (punishment) | Negative example: |
Where every instanse of the response is followed by the consequence | Define continuous reinforcement schedule |
Only some responses are reinforced | Define partial reinforcement schedule |
In operant conditioning, a reinforcement schedule in which a specific number of responses are required before a reinforcer is delivered; for exampled FR5 means that reinforcement arrives after every fifth response | What is a fixed-ratio (FR) schedule? |
In operant conditioning with a fixed-ratio (FR) schedule of reinforcement, a brief pause following a period of fast responding leading to reinforcement | What is postreinforcement pause? |
In operant conditioning, a reinfocement schedule in which the first response after a fixed amount of time is reinforced; thus, FI 1-m means that reinforcement arrives for the first response made after a one-minute interval since the last reinforcement | Define Fixed-interval (FI) schedule |
In operant conditioning, a reinforcement schedule in which a certain number of responses, on average, are required before a reinforcer is delivered; thus, VR5 means that, on average, every fifth response is reinforced | Define Variable-ratio (VR) schedule |
A reinforcement schedule in which the first response after a fixed amount of time, on average, is reinforced; thus, VI 1-m means that the first response after one minute, on average, is reinforced | Define variable-interval (VI) schedule |
A reinforcement schedule in which the organism can make any of several possible responses, each of which may lead to a different outcome reinforced according to a different reinforcement schedule | Define concurrent reinforcement schedule |
The principle that an organism, given a choice between multiple responses, will make a particular response at a rate proportional to how often that response is reinforced relative to the other choices | Define Matching law of choice behaviour (Hernstein, 1961) |
The study of how organisms allocate their time and resources among possible options | What are behavioural economics? |
In behavioural economics, the allocation of resources that maximises subjective value or satisfaction | What is a bliss point? |
The theory that the opportunity to perform a highly frequent behaviour can reinfoce a less frequent behaviour; later refined as the response deprivation hypothesis | What is the Premack principle? |
A refinement of the Premack principle stating that the opportunity to perform nay behaviour can be reinforcing if access to that behaviour is restricted | What is the response deprivation hypothesis? |
Time it took for a cat to escape from a puzzle box. Time declined over trials. Behaviour that leads to a satisfying outcome increases in the future | What was Thorndike's experiment? |
Operant | If the outcome occurs regardless of response, this is ____ conditioning |
Classical | If the outcome is contingent on a response, this is ____ conditioning |
Instrumental response -> Appetitive stimulus -> response increases | Positive Reinforcement stages |
Instrument response (avoidance) -> aversive stimulus stops -> response increases OR instrumental response - No aversive stimulus -> response increases | Negative reinforcement (escape) stages |
Instrumental response -> aversive stimulus -> response decreases | Positive punishment stages |
Previously rewarded response -> no appetitive stimulus (no reward) -> response decreases | Negative Punishment (extinction) stages |
