PTSD is also often treated with exposure therapy including ____ _____ therapy
trauma narrative
Explicit memory
Memory that can be consciously and deliberately retrieved and reported
Implicit memory
memory that is difficult or impossible to consciously and deliberately retrieve or report
Explicit and implicit memory are mediated by different _____ _____
neural circuits
explicit memory is largely mediated by (2)
- Hippocampus
- Neocortex
The hippocampus mediates the consolidation of _____ into _____
STM into LTM
The hippocampus is sensitive to _____ ______
context information i.e time and place
The hippocampus is sensitive to _______ _____ between stimuli, helping to “bind” various stimuli into a ______ _______
relational properties
unitary representation
During stress _____ is released from the adrenal glands.
Cortisol
High levels of cortisol _______ hippocampal functioning
decreases
High levels of cortisol result in a decrease in hippocampal functioning which then in turn: (3)
- Impairs LTM consolidation (why some people don’t remember)
- Impairs context information (why some people have flashbacks)
- Impairs binding sensory experiences into unitary representations (why some people recall fragments of a traumatic event)
High levels of cortisol can _____ amygdala functioning
Increase
The amygdala mediates (3), resulting in _____ ____ ____ without the benefits of hippocampal processing
- Fear
- Anxiety
- Conditioning
Strong fear conditioning
Explicit memories are mediated in the _____ which has ______ connections to the amygdala
cortex
inhibitory
Trauma narrative therapy aims to _____ the discrepancy between _____ memories of traumatic events and _____ memories of those events
reduce the discrepancies between explicit an implicit memories of traumatic events
Trauma narrative therapy aims to do what to the hippocampus and amygdala (2)
- increase activation of the hippocampus (more real/coherent memory of the trauma)
- increase inhibition of amygdala by the neocortex (reduce fear and anxiety)
Sometimes in narrative therapy, patients are asked to (2)
- Write out details of traumatic events
- Read the narrative repeatedly
Just like in anxiety and depression people with trauma tend to have _____ _____
cognitive distortions
