Document Summary

Input processed & stored in short or long-term. Participants saw displays of letters & asked to recall as many as possible. Row recall- participants see same kind of array in 2nd part. Longer time before recall, worse memory for contents of row (decay in memory) High capacity to store full arry in order to perform row-report. Very brief: starts to decay immediately (<1000 ms) Compare memory for visual task to auditory version: Echoic memory (mental echo)- much longer than vision. How much info can we pass thru copper wire & can people acquire. Or conversation (information source, transmitted as speech, send thru channel, reciever recieves & decodes & processed) Channel capacity - amount of info that comes thru. Messages are transmitted & encoded & decoded i. e. binary. Incoming info (sensory memory) ---> early analysis (process information) ---> short-term memory buffer (rehearse or loss) ---> information) ---> short-term memory buffer (rehearse or loss) ---> long-term or secondary memory.
