Unconditioned Stimulus (UCS)
The learned ability to tell the conditioned stimulus apart from other, similar stimuli that don’t signal the UCS.
The initial stage of classical conditioning, when a neutral stimulus is repeatedly paired with a UCS until it becomes a CS.
Reinforcement delivered after a set, unchanging number of correct responses (e.g., every 5th response).
Using a behavior someone already does often as the reinforcer for a behavior they do less often.
Removing a desirable stimulus after a behavior to make the behavior less likely to happen again.
Reinforcement delivered after an unpredictable number of responses — produces the highest, steadiest response rate (e.g., slot machines).
Removing an unpleasant stimulus after a behavior to make the behavior more likely to happen again.
An unlearned, automatic response to an unconditioned stimulus (e.g., salivating at food).
A stimulus that naturally and automatically triggers a response, with no learning required (e.g., food).
Reinforcing successively closer approximations of a target behavior until the exact behavior appears.
Responding the same way to stimuli that merely resemble the original conditioned stimulus.
The learned response to a conditioned stimulus, once that stimulus has been paired with a UCS.
The reappearance of an extinguished conditioned response after a rest period, with no new conditioning.
Reinforcement delivered for the first correct response after an unpredictable amount of time has passed.
Reinforcement delivered for the first correct response after a set amount of time has passed.
Adding an unpleasant stimulus after a behavior to make the behavior less likely to happen again.
The gradual weakening and disappearance of a conditioned response when the CS is no longer paired with the UCS.
A previously neutral stimulus that, after repeated pairing with a UCS, comes to trigger a learned response on its own.
Adding a desirable stimulus after a behavior to make the behavior more likely to happen again.
Using an already-established CS to condition a new, neutral stimulus, without the original UCS present.
