Brown, Lewis, Brown, Horn, and Bowes (1982) investigated drug-induced amnesia as a way of shedding light on organically produced amnesia. They first presented participants with a list of words to learn and then injected the participants with either lorazepam (which pro- duces amnesia) or saline. After 1.5 hours they asked all participants to recall the words they had learned. They also asked the same participants to learn a list after the drug had been injected and to recall it after 1.5 hours. If lorazepam interferes with the storage of material in memory, then recall only of the second list should be affected. If lorazepam interferes with retrieval rather than storage, then recall of both lists should be disrupted. What statis- tical test would be appropriate for analyzing these data? This is a case in which you do not know how to perform the analysis, but you should be able to describe the design. (Note: Recall of the list learned before the injection was unaffected, but the list studied after the administration of the drug was poorly recalled.)
