PSYC 2050U Chapter Notes - Chapter 13: Temporal Lobe, Anterograde Amnesia, Retrograde Amnesia
Document Summary
There are several kinds of learning and memory. Amnesia is a severe impairment of memory, usually a result of accident or disease: retrograde amnesia common, loses memories before an event. Difficulty retrieving memories: anterograde amnesia difficulty forming new memories after an event. Loss of the medial temporal lobe that involves the hippocampus, can include memory loss. The hippocampus is a medial temporal lobe structure that is important for learning and memory. Delayed non-matching to sample task this is a test for object recognition: declare what objects they have not seen previously. Individual must respond to the unfamiliar stimulus in a pair of stimuli. Removal of the adjacent hippocampus impairs performance on tests. We need at least one functioning medial temporal lobe that includes the hippocampus in order to make new declarative memories. Lesions of the amygdala had no effect on declarative memories. Lesions of hippocampus paired with nearby cortex profoundly impaired the formation of new declarative memories.
