*
False alarm rates and the difference score (Re-paired false alarm rate minus Single Repeat false alarm rate) used by Kroll et al. (1996) to assess associative memory for Experiments 1–5. Numbers in parentheses indicate the standard error of the mean. In all five experiments, the difference score was smaller for the patients with hippocampal damage (H) than for the control volunteers (CON).
