Document Summary
Encoding & retrieval and exceptional memory: overview, causes of forgetting, interactions between encoding and retrieval, exceptional memory performance, stage theory of memory, hypothetical stages. Forgetting: retrieval might be insufficient: causes of forgetting in ltm, inadequate encoding. Information is not attended to or not transferred to. Never reached ltm to begin with: decay. Memory traces decay in strength over time. Passage of time, memory traces decay (not a huge factor) Memories learned before or after some given memory: interference interfere with retrieval. Doesn"t play as important a role in forgetting as interference. Interpretation; gradually modify to suit until original is gone: retention functions, the longer the retention interval (time between learning and retrieval), the greater the chance of forgetting. Possible explanations: primary effect (many first times, more memorable) or neurological account: time of best cognitive functioning (optimal state, remember more; brain functions better: interference. Caused by one memory competing with another memory.
