Document Summary
Memory is a process of encoding (memorizing), storing, and retrieval. Iconic memory- a momentary sensory memory of visual stimuli; a photographic or picture image memory lasting no more than a few tenths of a second; Echoic memory- momentary sensory memory of auditory stimuli. George miller (1956)- magical number of 7 +/- 2 chunks (like abc vs. tzx)for memorizing string of numbers/letters; capacity limit . Acoustic similarity is similarity in sound; semantic similarity is similar in. When people need to memorize in a short term, acoustic similarity seems to meaning be the process behind it (memorizing by sound rather than meaning) Word length effect - the longer a string of words, the harder it is to remember more. Information in long-term memory is stored as a network of chunks. A chunk is a familiar pattern that can be used as a unit. It takes about 8 seconds to create a chunk. Need about 50,000 chunks to be a master.
