Implicit Memory
Implicit memory is described as memory that impacts an indi- vidual without his or her conscious awareness (see Schacter, 1987). According to the Ehlers and Clark cognitive model (Ehlers & Clark, 2000), individual differences in the salience of traumatic cues at the time of the trauma result in differential priming of perceptual cues, privileging traumatic stimuli with a processing advantage. This model posits that individuals with PTSD may orient readily to idiosyncratic trauma cues in the environment, and have difficulty shifting their attention away from these cues. These cues may be activated with extremely brief exposure to cues, or to cues which only partially or tangentially resemble the original stimulus. The heightened perceptual awareness may then trigger memories of the trauma via cue-driven, involuntary retrieval. Thus, according to this model of PTSD, the susceptibility to perceptual priming, or implicit memory, for trauma cues will
contribute to PTSD symptom development and maintenance in survivors of trauma. A survivor of an assault, for instance, may not understand what triggered a recent flashback, without realizing that someone near her was wearing the same aftershave as her assailant. In this example, she would have unconsciously oriented to a trauma cue (the aftershave), and experienced involuntary retrieval of the traumatic memory (the flashback).
Explicit Memory
The Ehlers and Clark cognitive model of PTSD also posits that trauma survivors with PTSD will evidence decreased explicit memory for traumatic stimuli as compared to survivors without PTSD and nontraumatized controls.
Explicit memory, or concep- tual priming, consists of memory that has been integrated into the autobiographical memory in an organized fashion. Increased ex- plicit memory for traumatic material competes with stimulus- driven implicit memory for traumatic material. Thus, increased explicit memory for traumatic material can inhibit implicit mem- ory (which facilitates involuntary, cue-driven retrieval) for this material, decreasing the symptoms of PTSD."

Also, just to add, I do notice a correlation in my ability to recognise and, more importantly acknowledge and self validate my bodily sensations, with a decrease in frequency of unexplained physical symptoms such as rashes on skin. My chronic back pain is linked to pent up emotion and I have more recently had phases where I have no pain at all. ( I have had every test to rule out anything physical) So when I talk about the self validation, I think this has only come with internalising my therapist. It has taken a long time to build up trust, not surprising at all, but I think this plays a big part in recovery and it’s just not automatic that one will gain this in any therapy session in a set amount of time. The brain is very malleable, at age 22 ( I think the last post said) and , even at my age (50) it has every chance of creating neural pathways that are there waiting to be connected. ‘The neuroscience of human relationships’ Cozolino, is a really interesting book and makes you realise how key close human relationships are in our brain development as a baby/child. But also beyond that....my relationship with my therapist will be my key to my recovery.
