Self-referential false associations: A self-enhanced constructive effect for verbal but not pictorial stimuli

Area of Science:

• Cognitive Psychology
• Neuroscience

Background:

• Memory is understood as a reconstructive process, but the mechanisms of false association formation and the self's role are not well-understood.
• Experimental evidence for the construction of false associations involving non-presented stimuli in episodic memory is limited.
• The specific influence of self-reference on the creation of these false memories requires further investigation.

Purpose of the Study:

• To investigate the construction of false associations involving non-presented stimuli in episodic memory.
• To determine the role of self-reference in the formation of these false associations.
• To explore whether self-enhanced effects differ between word and picture stimuli.

Main Methods:

• Two experiments utilized Deese/Roediger-McDermott (DRM) word and picture lists.
• Participants were exposed to stimuli paired with either their own name (self-reference) or another name ('Adele', other-reference).
• Memory for presented and non-presented (lure) items and their associations was subsequently tested.

Main Results:

• Participants falsely recalled non-presented lure words and pictures as presented.
• Participants misremembered the pairing of lures with the referenced name (self or 'Adele').
• A greater number of critical lure-self associations were constructed compared to critical lure-other associations for word stimuli, but not for picture stimuli.

Conclusions:

• False associations involving non-presented stimuli can be constructed in episodic memory.
• Self-reference enhances the construction of false associations, particularly for word stimuli, suggesting a self-enhanced constructive effect.
• Findings support the spreading-activation account of constructive episodic memory, highlighting the interplay of relational and item-specific processing.
