Choice-induced preference predicts delayed but not immediate decision-related memory benefits

Agency has been shown to enhance memory, such that when individuals have the opportunity to choose what they learn, they form stronger memories. Previous research shows that giving individuals the opportunity to choose increases the value of selected options, and this mechanism could generalize to learning environments and drive memory enhancements. Fifty-three participants completed rating, encoding, and recognition phases of a choice-memory task. The ratings were used to determine preexisting preferences for the hiragana characters that were used as occluder screens in the encoding task. During encoding, participants either actively selected (choice trials) or were instructed to select (fixed) occluder screens to reveal object images that were intentionally encoded for a later memory test. Memory was tested at a 24-hour delay test, and a subset also completed a test immediately after encoding. We found that the opportunity to choose increased both memory (p < 0.001) and selection-induced preference for occluder screens (p < 0.001). There was a significant positive relationship between choice-memory benefits (choice>fixed) at the delayed test and choice-related increases in selection-induced preference (choice>fixed; p < 0.05). However, this relationship was not apparent at the immediate test (p = 0.76) suggesting a role for consolidation-related processes. These results suggest that giving individuals agency increases value for learning, which in turn drives consolidation-dependent memory enhancements.
