Mean (±SEM) number of correctly remembered details per recalled image during the free-recall test for each reactivation group across all three retention intervals: 1 h, 9 days, and 28 days. This index is more revealing of the quality/precision of the memory for each recalled image. In the 28-day condition, the participants in the Descriptive group recalled significantly more details per image than the participants in the Distractor and Control groups (ps < 0.05), a finding that was not observed in the Component group. Hence, only the descriptive reactivation improved precision retention
