Are emotionally charged lures immune to false memory?

Area of Science:

• Cognitive Psychology
• Memory Studies

Background:

• The Deese-Roediger-McDermott (DRM) paradigm is a standard method for inducing false memories.
• Emotional stimuli are known to influence memory processes, but their role in DRM-induced false memories requires further investigation.

Purpose of the Study:

• To investigate whether emotional words elicit the false memory effect within the DRM paradigm.
• To examine how the presence and presentation format of emotional words at study impact false recognition of emotional critical lures.

Main Methods:

• Utilized the DRM task with lists of nonemotional associates targeting emotional or nonemotional critical lures.
• Employed remember-know judgments for recognition memory assessment.
• Manipulated the presence and study-test overlap of emotional nonlure words.

Main Results:

• Significant false "remembering" of emotional critical lures occurred even without their initial presentation.
• Including emotional nonlure words at study more than doubled false recognition of emotional lures.
• False memory for emotional lures decreased when emotional study words were also present on the recognition test.
• Participants misremembered nonemotional lures more frequently but rated emotional lures as "remembered" more often post-recognition.

Conclusions:

• Emotional stimuli can indeed induce false memories in the DRM paradigm.
• The presentation context of emotional words significantly modulates false memory effects, with study-list emotional words offering a protective effect.
• Distinctions exist between recognizing an item as "old" and the subjective experience of "remembering" it, particularly for emotional content.
