Summary
A source-monitoring model accurately explained recognition memory data, suggesting similar cognitive processes underlie different memory tasks. This highlights item detection and source identification in memory judgments.
Area of Science:
- Cognitive Psychology
- Psychology
Background:
- Source monitoring and process-dissociation are key memory research paradigms.
- Understanding the cognitive processes in recognition judgments is crucial for memory research.
Purpose of the Study:
- To test a 2-high-threshold model of source monitoring against empirical data.
- To compare the fit of the source-monitoring model with process-dissociation and extended process-dissociation models.
Main Methods:
- Applied a 2-high-threshold source-monitoring model to source-monitoring and process-dissociation data.
- Collected data varying source and distracter similarity to test model predictions.
Main Results:
- The 2-high-threshold source-monitoring model demonstrated a good fit to both data sets with identical parameters.
- Process-dissociation and extended process-dissociation models did not fit the collected data.
- Parameter values for detection (D) and source discrimination (d) behaved as predicted.
Conclusions:
- The cognitive processes underlying recognition judgments are consistent across source-monitoring and process-dissociation procedures.
- Four core cognitive processes are identified: item detection, source identification, recognition guessing, and source guessing.
- The study discusses the potential influence of unconscious memory through guessing processes.
