Limitations To Memory Research
There are several limitations to his work on memory. The most important one was that Ebbinghaus was the only subject in his study. This limited the study’s generalizability to the population. Although he attempted to regulate his daily routine to maintain more control over his results, his decision to avoid the use of participants sacrificed the external validity of the study despite sound internal validity. In addition, although he tried to account for his personal influences, there is an inherent bias when someone serves as researcher as well as participant. Also, Ebbinghaus' memory research halted research in other, more complex matters of memory such as semantic and procedural memory and mnemonics

Famous quotes containing the words limitations, memory and/or research:
“The limitations of pleasure cannot be overcome by more pleasure.”
—Mason Cooley (b. 1927)
“‘Tis of the essence of life here,
Though we choose greatly, still to lack
The lasting memory at all clear,
That life has for us on the wrack
Nothing but what we somehow chose;
Thus are we wholly stripped of pride
In the pain that has but one close,
Bearing it crushed and mystified.”
—Robert Frost (1874–1963)
“If politics is the art of the possible, research is surely the art of the soluble. Both are immensely practical-minded affairs.”
—Peter B. Medawar (1915–1987)
