Systematically reducing schematic information during encoding differentially impacts true and false memory at...

Area of Science:

• Cognitive Psychology
• Neuroscience
• Human Memory

Background:

• Schemas aid memory encoding and retrieval, particularly benefiting older adults.
• Schema reliance can increase false memories for related information and impair memory for unrelated information.

Purpose of the Study:

• To investigate how manipulating contextualization and schematic information density affects true and false memory.
• To examine memory performance for schematic and nonschematic information in younger and older adults.

Main Methods:

• Systematically varied the ratio of schematic to nonschematic information during encoding.
• Tested memory for schematic and nonschematic targets across four encoding conditions.
• Included healthy younger and older adult participants.

Main Results:

• Both age groups showed better accuracy for schematic compared to nonschematic information.
• Reduced schematic information at encoding improved memory discriminability.
• Decreased false alarms to schematic lures and increased hits to nonschematic targets were observed with less schematic information.
• Decontextualization reduced false alarms to nonschematic lures.

Conclusions:

• Schemas significantly influence memory across the lifespan, but this effect is malleable.
• Manipulating the amount of schematic information at encoding can optimize memory performance.
• Findings offer insights into the effective use of schemas as memory supports for all ages.
