Fig. 1.

Controls (CON, black bars, n = 4) and E.P. (open bars) studied 48 three-word sentences (e.g., “Shark killed octopus”). Retention tests were given to controls after 2 weeks of study (1 session per week, 2 training trials per session) and to E.P. on 2 consecutive days (T1–T6) after each 4 week study period (2 sessions per week, 2 training trials per session). A,Percent correct cued recall of target words in response to the first two words in each sentence. Performance is shown for the pretest (Pre, before study) and after each study period.B, Percent correct forced-choice recognition when the first two words of each sentence were presented together with two possible target words. Performance is shown after each study period. The dashed line shows the score obtained by a group (n = 10) that received no study. Error bars show SEM. Asterisks indicate significant difference versus the no-study group (p < 0.05).
