Document Summary
Psyc 251 - chapter 8 & 9: long-term memory: memory: how we acquire information from experience, maintain it over time, & use it when relevant in order to guide behaviour & plan future action. Must determine which experiences to remember, & how to retrieve it when needed. Without memory, we wouldn"t be able to change & improve. Involves multiple processes, types, systems & tasks. Requires physical change in the nervous system. Is pervasive - most of the brain is involved in some type of memory. All types of memory have a common underlying representation: # & strength of synaptic connections between neurons. Location of memory processing & storage coincide. Interpretation of representations depend on its location in nervous system: strength of synaptic connections represent different things depending on where in the brain they are found. Accessed based on its content (not location in the brain: dissociation: performance differs across 2 tasks. Suggests that short-term & long-term memory are separable systems.
