How gist and association affect false memory: False recognition and gist rating norms

Area of Science:

• Cognitive Psychology
• Memory Research
• False Memory

Background:

• The Deese/Roediger/McDermott (DRM) paradigm is a standard method for investigating false memories.
• Previous research identified backward associative strength (BAS) as a key predictor of false memory in the DRM task, often confounded by prior recall tests.

Purpose of the Study:

• To collect new recognition norms for DRM lists, unconfounded by prior recall.
• To assess gist strength (GS) as a predictor of false memory.
• To disentangle the predictive roles of BAS and GS in false recall and recognition.

Main Methods:

• Norming of true and false recognition for 55 DRM lists without prior recall.
• Norming of DRM lists for perceived gist strength (GS).
• Multiple linear regression analyses using recognition data (with and without prior recall) and prior false memory norms.

Main Results:

• Prior recall tests inflated true recognition and the correlation between recall and recognition.
• Gist strength (GS) emerged as the strongest predictor of false recognition.
• Backward associative strength (BAS) was the strongest predictor of immediate false recall.
• A significant interaction showed that the influence of BAS decreased as GS increased, suggesting competition between these factors.

Conclusions:

• Gist strength (GS) is a more robust predictor of false recognition than backward associative strength (BAS) when prior recall is absent.
• Backward associative strength (BAS) remains crucial for predicting immediate false recall.
• The findings challenge the notion that BAS and GS simply reinforce each other, indicating a competitive relationship in false memory formation.
