Flashbacks and memory phenomena. A comment on "Flashback phenomena--clinical and diagnostic dilemmas".
Alarcon, Dickinson, and Dohn (J. Nerv. Ment. Dis., 170: 217-223, 1982) recently reviewed the phenomenon of memory flashback following use of hallucinogenic drugs. They point out that while there are a considerable number of explanations concerning the flashback mechanism, little is known about the real causes. This paper examines flashback following drug ingestion in the light of other memory phenomena concerned with "cued retrieval" effects. Such phenomena may include dream recall, delayed post-traumatic stress, mood influence on memory, and drug effects on memory. Rather than view flashbacks as "pathological" in some sense, it may be better to view them as instances of normal memory processes, which may, nevertheless, be accompanied by emotional distress. Such a view relates flashbacks to a wider memory literature, and also makes them amenable to investigation using research designs derived from that literature.
