To do well on the exam, you will need to know the material covered in class notes and the text that addresses the concepts listed below. Learning (Ch 7) Classical conditioning: A set procedures used to investigate how organisms learn about the signaling properties of events. Classical conditioning involves learning relations between events condititioned and unconditioned stimuli that occur outside of ones control. US- Unconditioned Stimulus – A stimulus that automatically leads to an observable response prior to any training. NATURAL STIMULUS UR- Unconditioned Response – The observable response that is produced automatically, prior to training, on presentation of an unconditioned stimulus. NATRUAL RESPONSE CS- Conditioned Stimulus – the neutral stimulus that is paired with the unconditioned stimulus during classical conditioning. (RINGING OF BELL) CR- The acquired response that is produced by the conditioned stimulus in anticipation of the unconditioned stimulus. (BELL RINGS DOG EXPECTS FOOD) forming the CS-US connection- CS should function as a signal that the US is about to occur Acquisition, Conditioned responding becomes stronger with repeated CS-US pairings. The more times a dog hears the stimulus (tone) paired with the US (food), the stronger the conditioned response becomes. extinction, Conditioned responding diminishes when the CS (after conditioning) is presented repeatedly without the US. spontaneous recovery, Conditioned responding that has disappeared in extinction is recovered spontaneously with the passage of time. After extinction, a dog no longer responds to the CS (tone). After a rest period the dog will again respond when presented with a CS(tone).

stimulus generalization- In CS occurs when a new stimulus that resembles the conditioned stimulus, elicits the conditioned response. Responding to a new stimulus in a way similar to the response to an established CS stimulus discrimination- A stimulus similar to the conditioned stimulus(cs) fails to evoke a conditioned response (CR). Occurs when original CS predicts US, but similar stimuli don’t. Subject learns to discriminate original stimulus form similar ones. second-order
