One Problem with using a single-subject design to examine memory (as Ebbinghaus did) is that:
1) The subject tested may not be representative of the larger population. 2) The results of the study may not generalize to the larger population.
The fact that participants in Sperling's whole report experiment reported having briefly seen all the items in the display suggested to Sperling that:
Participants had stored all the items in iconic memory but that they faded too quickly to be recalled.
Assume that an individual is given a repeated memory task involving the following items presented in the following order: B, C, D, E, F, G. According to Hulls Theory (Trace Conditioning) which item is between no remote associations?
