Metamemory Reactivity in Source Monitoring
SymposiumTalk-03
Presented by: Marie Luisa Schaper
Soliciting metamemory judgments can alter memory—a phenomenon known as judgment reactivity. While reactivity effects on item memory (e.g., enhanced recognition) are well established, little is known about their impact on other memory components such as source memory (remembering where information came from). Across a series of experiments, we compared reactivity effects of item-memory predictions (Judgments of Learning, JOLs) and source-memory predictions (Judgments of Source, JOSs) on both item and source memory within a source-monitoring paradigm. Participants studied items (statements or words) presented by one of two sources and either made JOLs, JOSs, or no judgments (control). At test, they remembered both the items and their sources. Replicating prior work, metamemory judgments enhanced item memory relative to control, particularly for simple word materials. This positive reactivity occurred for both JOLs and JOSs. In contrast, source memory was impaired by both types of judgments. This dissociation suggests that making metamemory judgments may shift participants’ goal toward item encoding at the expense of source encoding—potentially reflecting a goal prioritization when resources are limited. Theoretical implications for reactivity and metamemory monitoring are discussed.
