Effects of imagery rescripting and imaginal exposure on voluntary memory

Area of Science:

• Psychology
• Clinical Psychology
• Trauma Studies

Background:

• Trauma-focused imagery-based interventions like Imagery Rescripting (ImRs) and Imaginal Exposure (ImE) effectively reduce PTSD symptoms.
• Concerns exist that these interventions might negatively impact voluntary memory recall.

Purpose of the Study:

• To investigate whether ImRs and ImE distort voluntary memory of an analogue trauma in healthy participants.
• To assess the impact of these interventions on different types of memory recall.

Main Methods:

• 120 healthy participants watched a trauma film.
• Participants were randomly assigned to receive one session of ImRs, ImE, or a no-intervention control (NIC).
• Voluntary memory was assessed via free recall, cued recall, and recognition tasks across multiple sessions.

Main Results:

• Neither ImRs nor ImE impaired performance on cued recall or recognition tasks compared to NIC.
• Imaginal Exposure (ImE) significantly increased correct details in the free recall task compared to ImRs and NIC.
• No evidence was found to support the hypothesis that these interventions impair voluntary memory.

Conclusions:

• The findings suggest that ImRs and ImE do not impair voluntary memory recall in healthy individuals.
• ImE may even enhance certain aspects of memory recall, such as free recall accuracy.
• Imagery-based interventions appear to be safe concerning voluntary memory function.
