The role of age of acquisition in memory: Effects on judgements of learning and recall

摘要

Judgements of learning (JOLs) are self-made predictions of the likelihood that one will later recall information. The influence of stimulus characteristics on JOLs and recall continues to receive attention, yet there are still a number of unexplored lexical word features that may exert an effect on mnemonic processing. Using a standard cue-target paradigm, we focused on the role of word age of acquisition (AoA) and evaluated the role of both cue and target AoA on responses. We replicated the robust delayed-JOL effect and used a novel items analysis approach to examine the relationship between intrinsic word features and accuracy and reaction times for both JOLs and recall. A consistent effect of target AoA was found, even after controlling for a range of covariates previously shown to impact JOLs and recall. These results expand the role of AoA in word processing and suggest that it is a key variable in memory and metacognition; they also support Koriat's (1997) cue utilization framework.
