German Psychologist
-First to measure and test memory
-Countered Wundt's claims about opacity of higher mental processes
-Nonsense Syllables (CVC)
-----Dealt with problem of associated meaning
-----Serial learning task
-Studied memory process as it happened
-Confounds: N=1 controlled life conditions; scrupulously consistent
-Method of Savings - Findings:
-----(early) what we now know as 'STM Capacity'; Max CVCs repeasted accurately after just one reading = 7
-----Effect of increased repititions
-----Advantage of distributed practice
-----The time course of forgetting-->the forgetting curve
-Forgetting Curve:
-----x-axis = interval between original learning of CVCs and memory test (days)
-----y-axis = average percentage of information retained
-----rapid forgetting of some information relatively soon after Ebbinghaus learned the CVCs
-----very little memory loss of the remaining information over the course of the followinf several weeks
