Generative processing and emotional false memories: a generation "cost" for negative false memory formation but only...

Area of Science:

• Cognitive Psychology
• Memory Research
• False Memory

Background:

• Memory-enhancing techniques often increase false memories.
• The generation effect (creating information) typically reduces false memories.
• Previous studies found generation reduced false memories, possibly via item distinctiveness.

Purpose of the Study:

• Investigate how generative processing affects memory for valenced stimuli.
• Examine the impact of delayed retention on the generation effect and false memories.
• Determine if valence and encoding method interact to influence long-term false recognition.

Main Methods:

• Utilized the Deese/Roediger-McDermott (DRM) paradigm.
• Participants either read or generated list items.
• Tested memory for critical lures (potential false memories) immediately and after a one-week delay.
• Stimuli included negative and neutral valenced items.

Main Results:

• Immediate testing showed no difference in false recognition between read and generate conditions for any valence.
• After a one-week delay, false recognition increased in the generate condition, but only for negative stimuli.
• This indicates a valence-specific generation effect for false memories under long-term retention.

Conclusions:

• Generative processing can increase false memories, particularly for negative stimuli, after a long delay.
• Item-specific and relational processing during encoding interact with long-term retention and stimulus valence.
• The findings challenge the notion that generation always reduces false memory susceptibility.
