Table 1.

Relative Levels of Search, Strength Differences, and Retrieval Success Presented for Each of the Three Comparisons: Remembered versus Classify, Forgotten versus Classify, and Study Level

	Remembered vs. Classify	Forgotten vs. Classify	Study Level
Search	++ vs. absent	+++ vs. absent	Some decrease with strength
Strength	++ vs. absent	+ vs. absent	+ vs. ++ vs. +++
Retrieval success	+++ vs. absent	Absent	Equal

The overlap of all three comparisons involves varying degrees of search and strength. Search is engaged during remembered and forgotten recall trials, relative to a baseline classification task, and can be isolated from strength by excluding effects of study level. Differences in memory strength are highlighted by comparing successful recall of low-, medium-, and high-study word pairs, and effects of search can be minimized by excluding the forgotten-versus-classify contrast. +++ = high; ++ = medium; + = low.
