Reinforcer
In operant conditioning, any event that strengthens the behavior it follows
A stimulus or an event that follows a response and increases the likelihood that the response will be repeated
Successive Approximation
Steps taken to achieve a desired behavior
Positive reinforcement
Increasing behaviors by presenting positive stimuli; such as food. A positive reinforcer is any stimulus that, when presented after a response, strengthens the response
Negative reinforcement
Increasing behaviors by stopping or reducing negative stimuli; such as shock. A negative reinforcer is any stimulus that, when removed after a response, strengthens the response. NOT A PUNISHMENT
Primary reinforcers
An innately reinforcing stimulus, such as one that satisfies a biological need
Conditioned reinforcers (secondary)
A stimulus that gains its reinforcing power through its association with a primary reinforcer
Punishment
An event that decreases the behavior that it follows
Positive Punishment
Adding something aversive that decreases the likelihood the behavior will be repeated
Negative Punishment
Withdraw a desirable stimulus to decrease the likelihood the behavior will be repeated
Continuous reinforcement
Reinforcing the desired response every time it occurs
Partial (intermittent) reinforcement
Reinforcing a response only part of the time; results in slower acquisition of a response but much greater resistance to extinction than does continuous reinforcement
Fixed-ratio schedule
In operant conditioning, a reinforcement schedule that reinforcers a response only after a specified number of responses
Variable-ratio schedule
In operant conditioning, a reinforcement schedule that reinforces a response after an unpredictable number of responses
Fixed-interval schedule
In operant conditioning, a reinforcement schedule that reinforces a response only after a specified time has elapsed
Variable-interval schedule
In operant conditioning, a reinforcement schedule that reinforces a response at unpredictable time intervals
