Summary
Perceptual fluency, or ease of processing, influences memory recognition. This study shows that perceptual fluency impacts both familiarity and recollection, affecting memory judgments even with deep encoding.
Area of Science:
- Cognitive Psychology
- Neuroscience
- Memory Research
Background:
- Perceptual fluency enhances item familiarity and past attribution in recognition tests.
- Its influence on recollection-based memory remains unclear.
- This study replicates Lucas and Paller (2013) using a letter-segregated method.
Purpose of the Study:
- To investigate if perceptual fluency affects recognition memory under conditions that promote recollection.
- To examine the role of low-level perceptual information in memory judgments.
- To replicate and extend findings on perceptual fluency and memory.
Main Methods:
- Participants performed a recognition task using event-related potentials (ERPs).
- Two block types were used: letter-segregated (LS) and letter non-segregated (LNS).
- In LNS blocks, new words were related or unrelated to studied words.
Main Results:
- Deep encoding enhanced recollection-based memory.
- An early P200 old/new effect (180-260 ms) in LNS blocks indicated early perceptual discrimination.
- Late LPC old/new effects (500-700 ms) suggested high recollection levels.
- Recognition was more accurate in LS blocks; LNS blocks showed more false alarms for related words.
Conclusions:
- Perceptual fluency, driven by low-level features, influences familiarity and recollection.
- Early perceptual differences can support recognition memory.
- The findings suggest perceptual fluency impacts both familiarity and recollection-based memory judgments.
