Memory. There may be nothing more important to human beings than our ability to enshrine experience and recall it. While philosophers and poets have elevated memory to an almost mystical level, psychologists have struggled to demystify it. Now, according to Daniel Schacter, one of the most distinguished memory researchers, the mysteries of memory are finally yielding to dramatic, even revolutionary, scientific breakthroughs. Schacter explains how and why it may change our understanding of everything from false memory to Alzheimer's disease, from (...) recovered memory to amnesia with fascinating firsthand accounts of patients with striking—and sometimes bizarre—amnesias resulting from brain injury or psychological trauma.

The relationship between emotional arousal and long-term memory is addressed in two experiments in which subjects viewed either a relatively emotionally neutral short story or a closely matched but more emotionally arousing story and were tested for retention of the story 2 weeks later. Experiment 1 provides essential replication of the results of Heuer and Reisberg and illustrates the common interpretive problem posed by the use of different stimuli in the neutral versus emotional stories. In Experiment 2, identical slides were (...) used in both the neutral and arousal stores. Two different stories were created by varying the narration that accompanied each slide. In both experiments, subjects who viewed the arousal story both experienced a greater emotional reaction to the story than did the subjects who viewed the neutral story, and subsequently exhibited enhanced memory for the story. Subjects in Experiment 2 who viewed the arousal story also recalled more slides than did the subjects who viewed the neutral story. This effect was greatest for story phase 2, the phase in which the emotional slide narration occurred. Because this enhanced retention of the story slides cannot be explained by any differences in the slides themselves, the results provide new evidence to support the contention that emotional arousal influences long-term memory in normal human subjects.
