Metamemory judgments have dissociable reactivity effects on item and interitem relational memory.

Abstract

Making metamemory judgments reactively changes item memory itself. Here we report the first investigation of reactive influences of making judgments of learning (JOLs) on interitem relational memory-specifically, temporal (serial) order memory. Experiment 1 found that making JOLs impaired order reconstruction. Experiment 2 observed minimal reactivity on free recall and negative reactivity on temporal clustering. Experiment 3 demonstrated a positive reactivity effect on recognition memory, and Experiment 4 detected dissociable effects of making JOLs on order reconstruction (negative) and forced-choice recognition (positive) by using the same participants and stimuli. Finally, a meta-analysis was conducted to explore reactivity effects on word list learning and to investigate whether test format moderates these effects. The results show a negative reactivity effect on interitem relational memory (order reconstruction), a modest positive effect on free recall, and a medium-to-large positive effect on recognition. Overall, these findings imply that even though making metacognitive judgments facilitates item-specific processing, it disrupts relational processing, supporting the item-order account of the reactivity effect on word list learning.
