Answer to Question 1

Answer: Surgeons removed portions of the medial temporal lobe in Patient H.M. in 1953 in order to treat his epilepsy. H.M. shows a severe case of anterograde amnesiahe is unable to learn new information, but can recall information he learned prior to the surgery. Subsequent research suggests that the anterograde amnesia reflects bilateral damage to the hippocampus. No impairments are noted in him for perceptual memory, motor memory, or sensory-motor memory.

Answer to Question 2

Answer: Perceptual learning allows us to recognize stimuli. An example would be knowing that a photo is that of your aunt. Stimulus-response learning involves connections between perceptual and motor systems; classical conditioning would be an example of a form of this type of learning (which involves a neutral stimulus taking on the capacity to elicit a reflexive response). Motor learning involves changes in neural circuits that control the musclesan example would be the changes that occur when a person first learns to drive a car. Relational learning is the most complex form, and can include the ability to recognize a stimulus using different sensory modalities or to recognize the relative location of an object among other objects in an environment.
