Document Summary
Encoding (gaining new information and placing in memory) Composed of different system with different properties memory stages. Duration: how long is it retained ended (memory trace) What is the capacity and duration for both? to find out, use tachistoscope. Implication: sensory memory has high capacity but low duration. Echoic memory last longer but still brief. Why is sensory memory important? we need to turn our attention to survive. Holds information from sensory memory that you are currently paying attention. Why can some remember more than 7? bc of chunking. Amount of information held varies, depends on what is being retained. Nonsense syllable (3 consonants with no meaning) More items on a list = more repetitions. Memory is quite fragile after remembering following questions. Recency effect (good for remembering first things on list bc it still in working. Rehearsing is not enough memory) vs primary effect (good for remembering last things on list)
