Imagery Rescripting induced transient forgetting of negative autobiographical memories

Area of Science:

• Cognitive Psychology
• Clinical Psychology
• Neuroscience

Background:

• Imagery Rescripting (ImRs) shows promise for emotional disorders linked to distressing memories.
• The effect of ImRs on memory recall, particularly the underlying mechanisms, needs further exploration.
• The retrieval competition hypothesis suggests ImRs may inhibit original memory representations, reducing their availability.

Purpose of the Study:

• To investigate the impact of ImRs on autobiographical memory recall.
• To test the retrieval competition hypothesis as a mechanism for ImRs-induced forgetting.
• To examine the temporal dynamics of memory recall following ImRs.

Main Methods:

• Two laboratory studies adapted the retrieval-practice paradigm using negative autobiographical memories from healthy participants.
• Experiment 1 compared ImRs and Imaginal Exposure (ImE) effects on memory recall.
• Experiment 2 explored temporal boundary conditions of ImRs-induced forgetting, using extralist cuing for recall testing.

Main Results:

• ImRs led to transient forgetting of negative autobiographical memories in healthy individuals.
• Memory recall for ImRs-intervened memories recovered after a 24-hour delay.
• Phenomenological ratings (valence, vividness, arousal) were collected pre- and post-intervention.

Conclusions:

• ImRs can induce temporary forgetting of negative memories, likely via inhibition of original representations.
• The forgetting effect is not permanent and memory recollection recovers over time.
• Caution is advised when applying ImRs-induced forgetting findings to clinical interventions or forensic contexts.
