Document Summary
How do memories get from short to long term: not merely time, build meaningful links, repetition (most effective when distributed over time; massed vs spaced training) Enhancement and impairment of consolidation: evaluation of importance: >evaluation of something as exciting or important can enhance its consolidation. However excessive adrenaline can also be detrimental; people in a panic may often have trouble remembering details. Adrenaline helps enhance memory not by acting directly on synapses in the brain but by raising levels of glucose in the blood and thus making it available to the brain. >injection of glucose shortly after an experience enhances memory of it. >animals that eat after a learning trial learn faster too. >tested human memory using list of words; 25g of glucose given before or after learning showed enhanced memory. Recent study (2011) claims that money enhances memory consolidation, but only for boring material.
