Presentation modality and mode of recall in verbal false memory

Area of Science:

• Cognitive Psychology
• Memory Studies
• Human Memory

Background:

• False memories, or the recollection of events that did not occur, are a significant area of research in cognitive psychology.
• Understanding the factors influencing false memory formation is crucial for various applications, including eyewitness testimony and therapeutic interventions.

Purpose of the Study:

• To investigate the influence of presentation modality (auditory vs. visual) on the formation and recall of false memories for semantically associated words.
• To determine the role of orthographic (spelling-based) information in modulating the presentation modality effect on false memory recall.

Main Methods:

• Experiment 1: Participants studied lists of semantically associated words presented either aurally or visually. Recall was then assessed through written or spoken responses.
• Experiment 2: The presentation modality effect was examined with an orienting task designed to promote orthographic encoding of aurally presented words.

Main Results:

• False written recall of critical intrusions was significantly lower for visually presented word lists compared to aurally presented lists.
• This presentation modality effect was eliminated when recall was spoken instead of written.
• The modality effect in written recall was also eliminated when participants engaged in an orthographic encoding task for aurally presented words.

Conclusions:

• The presentation modality effect in false memory recall is dependent on the use of orthographic information.
• Visual presentation facilitates the use of orthographic features, enabling better discrimination between true and false memories during written recall.
• The findings highlight the importance of encoding and retrieval processes, particularly the role of orthographic information, in the formation and susceptibility to false memories.
