Generalization: responding to a Generalization: responding to a second stimulus that’s similar to the second stimulus that’s similar to the original CSoriginal CS
Discrimination: ability to distinguish Discrimination: ability to distinguish between different stimuli between different stimuli
Extinction: gradual disappearance of a Extinction: gradual disappearance of a CR when the CS is repeatedly CR when the CS is repeatedly presented without the UCSpresented without the UCS
Spontaneous recovery: reappearance Spontaneous recovery: reappearance of a previously extinguished response of a previously extinguished response after time without exposure to the CSafter time without exposure to the CS
