Conceptual automaticity in recognition memory: levels-of-processing effects on familiarity

Area of Science:

• Cognitive Psychology
• Neuroscience
• Human Memory

Background:

• Recognition memory involves conscious recollection and familiarity.
• Prior research linked familiarity primarily to perceptual factors.
• Conceptual processing's role in familiarity remained less understood.

Purpose of the Study:

• To investigate if conceptual (meaning-based) processing influences familiarity in recognition memory.
• To differentiate the roles of processing levels and response timing on memory components.
• To explore the functional independence of recollection and familiarity.

Main Methods:

• Three experiments manipulated level of processing (LoP) and response-signal delays (500 ms, 1500 ms).
• Utilized recognition memory tasks with varying encoding depths (perceptual vs. conceptual).
• Employed the process dissociation procedure to quantify recollection and familiarity.

Main Results:

• Conceptual processing reliably enhanced recognition memory at both fast and slow response speeds.
• Semantic encoding led to more false alarms than non-semantic encoding, especially with fast responses.
• Recollection estimates increased with conceptual processing, while familiarity also showed an increase; recollection, unlike familiarity, was affected by response delay.

Conclusions:

• Familiarity in recognition memory can arise from prior conceptual processing, extending beyond perceptual influences.
• Recollection and familiarity appear to be functionally independent memory processes.
• Response-signal delay differentially impacts recollection and familiarity, supporting dual-process models of memory.
