When is schematic knowledge used in source monitoring?
1Department of Psychology, The University of North Carolina at Chapel Hill, 27599, USA.
Summary
When memory for information origin is poor, people use schematic knowledge to guess. This study found schema use in source monitoring only when recognition accuracy was low, with retrieval following an exponential growth pattern.
Area of Science:
- Cognitive Psychology
- Human Memory Research
Background:
- Source monitoring is crucial for distinguishing information origins.
- When source memory fails, individuals may rely on prior schematic knowledge to make inferences.
Purpose of the Study:
- To investigate the specific conditions influencing the use of schematic knowledge in source monitoring.
- To analyze the temporal dynamics of schema-based guessing.
Main Methods:
- Employed a response-signal technique to track the time course of responses.
- Utilized multinomial models to differentiate memory accuracy from guessing bias.
Main Results:
- Schema-based guessing in source monitoring was evident only when recognition performance was low.
- The retrieval of schematic knowledge followed an exponential growth function over time.
Conclusions:
- Schematic knowledge serves as a compensatory mechanism for deficient source memory.
- The findings offer insights into the interplay between memory retrieval and schematic processing in decision-making.
