The Role of Implicit Memory in the Development and Recovery from Trauma-Related Disorders

Abstract

Post-traumatic Stress Disorder is a chronic condition that occurs following a traumatic experience. Information processing models of PTSD focus on integrating situationally triggered sensory-emotional memories with consciously accessible autobiographical memories. Review of the nature of implicit memory supports the view that sensory-emotional memories are implicit in nature. Dissociation was also found to be associated with the development and severity of PTSD, as well as deficits in autobiographical memory. Moreover, disorganized attachment (DA) was associated with greater degrees of dissociation and PTSD, and like the defining neural activation in PTSD, was found to be associated with basal ganglia activity. In addition, subcortical neuroception of safety promotes a neurophysiological substrate supportive of social engagement and inhibition of fear-based responses. Furthermore, activation of representations of co-created imagined scenes of safety and secure attachment are associated with increases in this neurophysiological substrate. Repeated priming of secure attachment imagery was associated with modification of internal working models of DA along with reductions in dissociation and recovery from complex PTSD. In conclusion, it is posited that adequate recovery from extensive trauma experiences requires more than conscious elaboration of traumatic autobiographical memories and that the application of implicit nonconscious memory modification strategies will facilitate more optimal recovery.

Utilization of Presence Awareness in Trauma Therapy

“…Because the details and nuance of psychological trauma often exist in implicit memory [33], while accessing and processing trauma it is helpful to provide treatment interventions that helps clients access and process implicit traumatic memory. Implicit memory can be accessed through body awareness [33] EMDR (Eye Movement Desensitization Reprocessing (EMDR), (IFS) Internal Family Systems, (SE) Somatic Experiencing Body, and (AEDP) Accelerated Experiential Dynamic Reprocessing are all somatic-based treatments that have shown to be effective in treating the effects of implicit memory [34][35][36][37][38].…”

: The Effect of Traumatic Brain Injury on Memory

“…Both types of memory are differentiated in terms of conscious recollection. Implicit memory does not require conscious effort to retrieve, such as riding a bike and having a conversation ( 67 ). Conversely, explicit memory is a form of memory that requires conscious effort, such as facts or event recollection ( 68 ).…”
