								Autoshaping									 
								 | 
							
							
								 
								Movement toward and possibly contact with a stimulus that signals the availability of a positive reinforce, such as food. Also called sign tracking									 
								 | 
						
| 
								 
								Backward conditioning									 
								 | 
							
							
								 
								A procedure in which the conditioned stimulus is presented shortly after the unconditioned stimulus on each trial									 
								 | 
						
| 
								 
								Compound-stimulus test									 
								 | 
							
							
								 
								A test procedure that identifies a stimulus as a conditioned inhibitor if that stimulus reduces the responding elicited by a conditioned excitatory stimulus. Also called summation test									 
								 | 
						
| 
								 
								Conditional or Conditioned Response (CR)									 
								 | 
							
							
								 
								The response that comes to be made to the conditioned stimulus as a result of classical conditioning									 
								 | 
						
| 
								 
								Conditional or Conditioned Stimulus (CS)									 
								 | 
							
							
								 
								A stimulus that does not elicit a particular response initially, but comes to do so as a result of becoming associated with an unconditioned stimulus									 
								 | 
						
| 
								 
								Conditioned Emotional Response (CER)									 
								 | 
							
							
								 
								Suppression of positively reinforced instrumental behavior (e.g., lever pressing for food pellets) caused by the presentation of a stimulus that has become associated with an aversive stimulus. Also called conditioned suppression									 
								 | 
						
| 
								 
								Conditioned Suppression									 
								 | 
							
							
								 
								Suppression of positively reinforced instrumental behavior (e.g., lever pressing for food pellets) caused by the presentation of a stimulus that has become associated with an aversive stimulus. Also called Conditioned Emotional Response									 
								 | 
						
| 
								 
								Conditioning Trial									 
								 | 
							
							
								 
								A training episode involving presentation of a conditioned stimulus with (or without) an unconditioned stimulus									 
								 | 
						
| 
								 
								CS-US interval									 
								 | 
							
							
								 
								The amount of time that elapses between presentations of the conditioned stimulus (CS) and the unconditioned stimulus (US) during a classical conditioning trial. Also called Interstimulus Interval									 
								 | 
						
| 
								 
								Evaluative Conditioning									 
								 | 
							
							
								 
								Changing the hedonic value or liking of an initially neutral stimulus by having that stimulus associated with something that is already liked or disliked 									 
								 | 
						
| 
								 
								Explicitly unpaired control									 
								 | 
							
							
								 
								A procedure in which both conditioned and unconditioned stimuli are presented, but with sufficient time between them so that they do not become associated with each other									 
								 | 
						
| 
								 
								Inhibitory Conditioning									 
								 | 
							
							
								 
								A type of classical conditioning in which the conditioned stimulus becomes a signal for the absence of the unconditioned stimulus									 
								 | 
						
| 
								 
								Interstimulus interval									 
								 | 
							
							
								 
								The amount of time that elapses between presentations of the conditioned stimulus (CS) and the unconditioned stimulus (US) during a classical conditioning trial. Also called the CS-US interval									 
								 | 
						
| 
								 
								Intertrial interval									 
								 | 
							
							
								 
								The amount of time that elapses between two successive trials									 
								 | 
						
| 
								 
								Latency									 
								 | 
							
							
								 
								The time elapsed between a stimulus (or the start of a trial) and the response that is made to the stimulus
