Question

5) In conditioned emotional (fear) response experiments, the central structure that is highly implicated in mediating the learning and organization of the behavioral response is the medial prefrontal cortex a. True False 6) I am interested in understanding CRs to a stimulus that predicts delivery ofa reward. If my results demonstrate that animals sit by the CS and interact with it, in theory we could say that these animals are goal trackers. a. True b. False Relative to conditioned excitation, a conditioned inhibition (or CS-) is generally thought to serve asa safety signal or a signal for the absence of the US 7) a. True b. False Higher-order conditioning is: a. Also known as sensory preconditioning b. Involves generalizing a conditioned response to settings in which the CS is present without the US c. Involves demonstrating a conditioned response in a setting other than where the initial learning took place d. B&C;

Explanation / Answer

5. False. The prefrontal cortext is believed to exert top down control over subcortical structures to regulate appropriate behavioral responses. The medial prefrontal cortex plays role in the exinction of conditioned fear.

6.True. if the animals are watching over the conditioned stimulus, they are goal trackers, for example, if I feed dog, (biscuit) on visiting the shop on a daily basis, the dog would recognise me every time I step in to the shop anticipating for the biscuit.

7.True. Conditioned inhitbitions serves as a safety signal if the conditioned stimulus and unconditioned stimuls produce opposite reactions.

8.(d), the answer is "both b and c", In high order conditioning a second order conditioned stimulus is created by pairing it to the formerly conditioned stimulus. Sensory preconditioning is learning of association between two stimuli in the initial phase.
